Marine Pollution Essay Example

Marine Pollution Paper In the late 1 sass and early 1 sass, there were several controversies about dumping radioactive waste off the coasts of the United States by companies licensed by the Atomic Energy Commission, into the Irish Sea from the British processing facility at Windscreen, and into the Mediterranean Sea by the French Commissariat lingerie Atomize. After the Mediterranean Sea controversy, for example, Jacques Coaster became a worldwide figure in the campaign to stop marine pollution. Marine pollution made further international headlines after the 1967 crash of the oil tanker Torero Canyon, and after the 1 969 Santa Barbara oil spill off the coast of California. Marine pollution was a major area of discussion during the 1972 United Nations Conference on the Human Environment, held in Stockholm. That year also away the signing of the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, sometimes called the London Convention. The London Convention did not ban marine pollution, but it established black and gray lists for substances to be banned (black) or regulated by national authorities (gray). Cyanide and high-level radioactive waste, for example, were put on the black list. The London Convention applied only to waste dumped from ships, and thus did nothing to regulate Waste discharged as liquids from pipelines.

B) Specific Statement of the Problem * Direct discharge Pollutants enter rivers and the sea directly from urban sewerage and industrial waste discharges, sometimes in the form of hazardous and toxic wastes. Inland mining for copper, gold. Etc. , is another source of marine pollution. Most of the pollution is simply soil, which ends up in rivers flowing to the sea. However, some minerals discharged in the course of the mining can cause problems, such as copper, a common industrial pollutant, which can interfere with the life history and development of coral polyps. Mining has a poor environmental track record. For example, according to the united States Environmental Protection Agency, mining has contaminated portions of the headwaters of over 40% of watersheds in the western continental US. Much of this pollution finishes up in the sea. Land runoff Surface runoff from farming as well as urban runoff and runoff from the construction of roads, buildings, ports, channels, and harbors, can carry oil and particles laden with carbon, nitrogen, phosphorus, and minerals. This nutrient-rich water can cause fleshy algae and phytoplankton to thrive in coastal areas; known as algal blooms, which have the potential to create hypochondriacs by using all available oxygen. Polluted runoff from roads and highways can be a significant source of water pollution in coastal areas. About 75 percent of the toxic chemicals that flow into Upset Sound are carried postmaster that runs off paved roads and driveways, rooftops, yards and other developed land. * Ship pollution Ships can pollute waterways and oceans in many ways. Oil spills can have devastating effects. While being toxic to marine life, polycyclic aromatic hydrocarbons (Pass), found in crude oil, are very difficult to clean up, and last for years in the sediment and marine environment. Discharge of cargo residues from bulk carriers can pollute ports, waterways and oceans. In many instances vessels intentionally discharge illegal wastes despite foreign and domestic regulation prohibiting such actions. It has been estimated that container ships lose over 10,000 containers at sea each year (usually during storms). Ships also create noise pollution that disturbs natural lilied, and water from ballast tanks can spread harmful algae and authoritative species. Ballast water taken up at sea and released in port is a major source of unwanted exotic marine life. The invasive freshwater zebra mussels, native to the Black, Caspian and Capo Seas, Were probably transported to the Great Lakes via ballast water from a transoceanic vessel. Mines believes that one of the worst cases of a single invasive species causing harm to an ecosystem can be attributed to a seemingly harmless jellyfish. Nepotisms eyelid, a species of comb jellyfish that spread so it now inhabits estuaries in many parts of the world. It was first introduced in 1 982, and thought to have been transported to the Black Sea in a ships ballast water. The population of the jellyfish shot up exponentially and, by 1988, it was wreaking havoc upon the local fishing industry. Tenancy catch fell from 204,000 tons in 1 984 to 200 tons in 1993; sprat from 24,600 tons in 1 984 to 12,000 tons in 1 993; horse mackerel from 4,000 tons in 1 984 to zero in Now that the jellyfish have exhausted the zooplankton, including fish larvae, their numbers have fallen dramatically, yet they continue to maintain a stranglehold on the ecosystem. Invasive species can take over once occupied areas, facilitate the spread of new diseases, introduce new genetic material, alter underwater seascapes and jeopardize the ability of native species to obtain food. Invasive species are responsible for about $138 billion annually in lost revenue and management costs in the US alone. * Deep Sea Mining Deep sea mining is a relatively new mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of politically nodules or active and extraterritoriality vents at about 1 ,400 3,700 meters below the oceans surface. The vents create sulfide deposits, which contain precious metals such as silver, gold, copper, manganese, cobalt, and zinc. The deposits are mined using either hydraulic pumps or bucket systems that take ore to the surface to be processed. As with all mining operations, deep sea mining raises questions about environmental damages to the surrounding areas Because deep sea mining is a relatively new field, the complete consequences of full scale mining operations are unknown. However, experts are certain that removal of parts of the sea floor will result in disturbances to the benthic are, increased toxicity of the water column and sediment plumes from tailings. Removing parts of the sea floor disturbs the habitat of benthic organisms, possibly, depending on the type of mining and location, causing permanent disturbances. Aside from direct impact of mining the area, leakage, spills and corrosion would alter the mining areas chemical makeup. Among the impacts of deep sea mining, sediment plumes could have the greatest impact. Plumes are caused when the tailings from mining (usually fine particles) are dumped back into the ocean, creating a cloud of particles floating in the water. Two types of plumes occur: near bottom plumes and surface plumes. Near bottom plumes occur when the tailings are pumped back down to the mining site. The floating particles increase the turbidity, or cloudiness, Of the water, clogging filter-feeding apparatuses used by benthic organisms. Surface plumes cause a more serious problem. Depending on the size of the particles and water currents the plumes could spread over vast areas. The plumes could impact zooplankton and light penetration, in turn affecting the food web of the area. * Oil Oil spills cause huge damage to the marine environment but in fact are responsible for only around of he oil entering the seas each year. According to a study by the US National Research Council, 36% comes down drains and rivers as waste and runoff from cities and industry. Fertilizers Fertilizer runoff from farms and lawns is a huge problem for coastal areas. The extra nutrients cause transportation flourishing of algal blooms that deplete the waters dissolved oxygen and suffocate other marine life. Transportation has created enormous dead zones in several parts of the world, including the Gulf of Mexico and the Baltic Sea. * Seas of Garbage Solid garbage also makes its way to the ocean. Plastic gas, balloons, glass bottles, shoe s, packaging material if not disposed of correctly, almost Everett inning we throw away can reach the sea. Plastic garbage, which decomposes very slowly, is often mistaken for food by marine animals. High concentrations of plastic material, particularly plastic bags, have been found blocking the breathing passages and stomachs of many marine species, including whales, dolphins, seals, puffins, and turtles. Plastic six-pack rings for drink bottles can also choke marine animals. This garbage can also come back to shore, where it pollutes beaches and other coastal habitats. Sewage disposal In many parts of the world, sewage flows untreated, or under-treated, into the ocean. For example, 80% of urban sewage discharged into the Mediterranean Sea is untreated. This sewage can also lead to transportation. In addition, it can cause human disease and lead to beach closures. * Toxic chemicals Almost every marine organism, from the tiniest plankton to whales and polar bears, is contaminated with man-made chemicals, such as pesticides and chemicals used in common consumer products. Some of these chemicals enter the sea through deliberate dumping. For centuries, the oceans have been a convenient dumping ground or waste generated on land. This continued until the 1 sass, with dumping at sea the accepted practice for disposal of nearly everything, including toxic material such as pesticides, chemical weapons, and radioactive waste. Dumping of the most toxic materials was banned by the London Dumping Convention in 1 972, and an amended treaty in 1996 (the London Convention) further restricted what could be dumped at sea. However, there are still the problems of already-dumped toxic material, and even the disposal of permitted substances at sea can be a substantial environmental hazard. Chemicals also enter the sea from land-based activities. Chemicals can escape into water, soil, and air during their manufacture, use, or disposal, as well as from accidental leaks or fires in products containing these chemicals. Once in the environment, they can travel for long distances in air and water, including People once assumed that the ocean was so large that all ocean currents. Laotians would be diluted and dispersed to safe levels. But in reality, they have not disappeared and some toxic man-made chemicals have even become more concentrated as they have entered the food chain. Tiny animals at the bottom of the food chain, such as plankton in the oceans, absorb the chemicals as they feed. Because they do not break down easily, the chemicals accumulate in these organisms, becoming much more concentrated in th eir bodies than in the surrounding water or soil. These organisms are eaten by small animals, and the concentration rises again. These animals are in turn eaten by larger animals, which can travel large distances with their even further increased chemical load. Animals higher up the food chain, such as seals, can have contamination levels millions of times higher than the water in which they live. And polar bears, which feed on seals, can have contamination levels up to 3 billion times higher than their people become contaminated either directly from household environment. Products or by eating contaminated seafood and animal fats. Evidence is mounting that a number of man-made chemicals can cause serious health problems including cancer, damage to the immune system, behavioral problems, and reduced fertility.

A Deeper Understanding of the Stressors of Psoriasis Professor Ramos Blog

A Deeper Understanding of the Stressors of Psoriasis Society dictates of how beauty should be defined when it comes to how proportionate the person’s facial features are as it fits the golden ratio, and more importantly, how flawless a persons skin has as visibly seen by the eyes of the beholder. Nevertheless, the skin is the first line of defense when it comes to protecting the body from external harsh environment. Skin problems and illnesses are frequently noticeable and visible to others that even a physician can generally diagnose what a person has by looking at the abnormal skin level. The social stigma customarily correlated with different types of skin conditions is hard for people to cope with their skin issues and diseases, as well as negative reaction they receive from others. Moreover, many people suffer from variety of skin problems whether it is hereditary, autoimmune, infectious, environmental, or of unknown cause. Thus, it is the goal of this paper to look into a deeper understanding of one of the prevalent skin d iseases, such as psoriasis, though untreatable, yet can be prevented as long as the underlying causes are known intracellularly and externally. Fig. 1. Healthy skin and skin with psoriasis. â€Å"Growth and Shedding of Keratinocytes in Psoriasis.†Psoriasis Plaque, PubMed Health, https://www.ncbi.nlm.nih.gov/pubmedhealth/PMHT0030407/ Normally, the skin regenerates itself about once a month, or approximately every twenty-eight days (Pagano 18) or 4 weeks as shown in Fig. 1 in a healthy skin (Growth and Shedding of Keratinocytes in Psoriasis). However, in psoriasis, the process speeded up; the skin attempts to renew itself every three or four days instead of the twenty-eight days. The surface area becomes red, inflamed, extremely sensitive, visibly raised, and scaly (19). The word psoriasis is from the Greek word psora, which means â€Å"itch† (Raychaudhuri et al. 61). Psoriasis is a long term, immune-mediated inflammatory disease (IMID , a disease that lacks definitive etiology) that occurs from the hyperproliferation of skin cells, thus thickening the layer of skin, which causes erythema or redness, scaly silvery plaques, itching, and bleeding. It is genetically inherited from a mother or father who has the disease. Psoriasis is not an unusual disorder; a prevalence of 2%-4%, with a peak incidence between 15 and 25 years age and without sex predilection, has been reported (45). Fig. 2. Common affected areas in psoriasis. â€Å"Main Features of Psoriasis.†Psoriasis E-Chart.HC-HealthComm, loc. 63, hc-healthcomm.com The manifestation of psoriasis can be triggered by many factors. It can be triggered by external and internal environmental factors in genetically susceptible individuals. These factors include infections, drugs such as allergic drug reaction, antimalarial drugs, lithium, beta blockers, interferon alpha, withdrawal of systemic corticosteroids, local trauma (Koebner’s phenomenon), and emotional stress, as these correlates with the onset or flares of psoriatic lesions (Weinberg 11). These lesions are distributed symmetrically and frequently occur on the elbows, knees, lower back, and scalp. These plaques can be intensely pruritic and bleed when manipulated, referred to as Auspitz sign (12). Thus, emotional stress, drugs, and infections can trigger clinical signs and symptoms experienced by psoriatics such as itching, bleeding, and lesion at the more prominent body sites such as the knees, elbows, back, and scalp as shown in fig. 2. Fig. 3. Pathophysiology of psoriasis at a cellular level. â€Å"Evolution of Psoriasis and Immune Factors.† Psoriasis E-Chart.HC-HealthComm, loc. 51, hc-healthcomm.com In many diseases that most people suffer, it seemed psychological distress plays a huge role in the exacerbation of the disease. Doctors and many people believe psychological ‘stress’ to be a major triggering factor in many skin diseases, specifically psoriasis (Shuster 614). The correlation between skin and mind may be a result of the skin’s role as biological structure of transmitting information, and perhaps also the social response to the infectious nature of skin disease in the recent past; consequently a disorder of the skin may have a very severe effect on the mind (615). He infer this is the basis of the erroneous belief that mind is a significant etiological aspect in skin disease. Moreover, he believes that there is a strong proof that both mind and ‘stress’ transform certain skin circulatory and immune responses but in a direction which might be anticipated to improve psoriasis (615). Therefore, based on the belief by many expertise in the field of medicine, psychological stress can worsen psoriasis. There are many cases have been reported that stress can exacerbate psoriasis. Scientific research reports roughly 40% of cases in the beginning or worsening of psoriasis, psychosocial stress has been reported to play an important role (Gupta et al. 166). A few studies have been published that about 80% of patients with psoriasis are stress reactors. Many psychosocial intercessions have been reported to be a vital addition in the typical therapeutic management of psoriasis (166). Based on the study of 127 patients with plaque psoriasis who got admitted to Dermatology inpatient unit, the psychosocial stress measures such as major life events, psychological or personality factors, social support, and minor daily stressful events or hassles were used to evaluate the severity of the disease of psoriatic patients (168). Based on the result of the dermatologic measures that were done, it revealed that the high stress reactors (i.e. stress exacerbates psoriasis) had extensive psoriasis on he ad (face and scalp), neck, upper extremities, and genital area which are classified as â€Å"emotionally charged† because psoriasis in these anatomical parts are more likely to induce emotional reactions in the patients †¦ In retroactive study, the high stress reactors also reported a larger number of flare-ups of their psoriasis during the 6 months prior to admission (170). In this study, the psychocutaneous traits have identified the high stress reactors from the low stress reactors (i.e. less significant link of stress and psoriasis). The high stress reactors had more disfiguring psoriasis because it affected many regions of their body. Aside from what Gupta and his colleagues had mentioned above, another scientific study suggests that stress can cause psoriasis. Based on Al’Abadie et al research on the effects of stressful life events on the beginning and progress of psoriasis, their studies showed that psoriasis patients’ disease is affected by stressful events differing from 40 to 80% based on whether it is an acute or chronic stress, and based on patients self reports or responses based on standardized check-lists (199). They also added that stress can affect the immune system directly through neuroendocrine changes or indirectly through poor healthy habits in regards to diet and sleep, or by taking drugs such as alcohol and therefore lowering their immune system (199). They found that chronic stress of everyday struggles can worsen psoriasis (200). The results of the study supports that the experience of stress may take a significant part in the onset and exacerbation of psoriasis. Many credible researchers continue to emphasize stress as one of the causes of the progression of psoriasis. In the study performed by Griffiths and Richards, they stated that psoriasis suggested as a psychosomatic disorder wherein stress or psychological distress is a cause in expressing the disease. Also, in their article, â€Å"Psychological influences in Psoriasis,† emotional stress was mentioned as the most convincing precipitating factor in psoriasis (338). The result of their study reported over 60% of a sample of psoriasis patients who attended a specialty clinic were convinced that stress was the main reason to the cause of their psoriasis, and this was not related to the clinical severity of their condition as measured by the Psoriasis Area Severity Index (PASI) (338). In addition, they also examined the Psoriasis Life Stress Inventory (PLSI) which is another way in rating everyday life struggles or recurring substandard stress associated with having to live with pso riasis. They were able to identify that the two main factors to stress in psoriasis were â€Å"engaging in anticipatory and avoidance coping behavior, and belief of being evaluated on the basis of their skin† (qtd 339). Furthermore, they deduce that if psoriasis patients engage themselves in anticipatory and avoidance coping behavior which is not related to their skin condition, then it might be hypothesized that â€Å"thoughts related to stigmatization and rejection may be influencing such behavior† (qtd 339). In other terms, psoriasis patients are expecting horrible situation when they are not aware that this will actually happen. One good example would be a psoriasis patient will not take her children to a public water park for fear of being asked to leave the premise due to the fact that they have psoriasis even though this might never have occurred to them in the past. They tried to avoid this kind of situation because they feel being stigmatized because of the cl inical condition of their skin. Therefore, emotional or psychological stress of daily struggles with psoriasis manifests the progression of the disease. Fig. 4. Commonly affected areas of psoriasis and types of treatment. Armstrong, April W. â€Å"Psoriasis is a Common Condition Where the Skin Gets Red and Scaly; Psoriasis can Cause Itching, Discomfort, and Sometimes pain.† JAMA Dermatology, vol. 153, no. 9, Sep. 2017, p. 956. There are different types of treatment for psoriasis (see fig. 4). It can be topical medication, phototherapy, biological agents, oral medication, and diet. Though psoriasis can be stress related, having psoriasis self-help groups and group therapy that help the psoriatic patients to deal with the daily stresses related with their disease should be part of the whole therapeutic programs (Gupta et al. 172). The dermatologist should tailor the treatment plan based on patient individual needs since everybody has different and unique biochemical makeup. Though there is no cure for psoriasis, all the possible treatment mentioned above can possibly prevent the onset and exacerbation of the disease. Topical medications are used to treat the symptoms of psoriasis. Salicylic acid, corticosteroids and vitamin D analogues are few of the topical agents used to alleviate the symptoms of psoriasis. Raychaudhuri states that due to increased water loss and increased formation of keratinocytes in the skin, the skin becomes dry and itchy (246). Salicylic acid emollients are applied on the psoriatic skin to moisten the epidermal layer and prevent it from pruritus or itching (246). On the other hand, inflammation of the skin is another symptoms experienced by psoriatic patients. Since psoriasis can be an autoimmune disease, the keratinocytes in psoriasis are not well regulated causing an inflammatory response. Vitamin D has many important roles in immunity and the absorption of calcium according to Fett (163). Vitamin D supplement added in diet of psoriasis patients has a moderate or greater improvement in psoriasis in at least 50 percent of patients in five separate studies that have been r eported (164). Some psoriatic patients who take higher doses of vitamin D supplements completely resolved their disease (164). Vitamin D analogues are used to strengthen the immune system, and it binds to intracellular vitamin D receptors to regulate the genes responsible in the proliferation of keratinocytes and keratin (Raychaudhuri 249-50). The same effect as vitamin D ointment happens when corticosteroid is used to treat inflammation in psoriasis. Corticosteroid, a steroid hormone, is produced in the adrenal cortex regulates inflammatory response. It attaches to glucocorticoid receptor in the cell and regulates the gene responsible in inflammation (248). Therefore, the symptoms of psoriasis such as itching and inflammation can be treated with salicylic acid, vitamin D compounds, and corticosteroid topical agents. Another treatment used to relieve the symptom of psoriasis is by the use of phototherapy. Ultraviolet (UV) light therapy is used as a phototherapy to slow the growth of the affected skin cells in psoriasis (Raychaudhuri 170). Since psoriasis is a T cell mediated disease, the abnormal functioning T lymphocytes attacks the skin cells causing an inflammatory response by increasing the keratinocyte proliferation and keratinization (Dolgin 1219). Thus, with phototherapy, it slows down the process of the T lymphocytes in attacking the keratinocytes. Aside from the topical agents and phototherapy, diet also plays a vital role in the treatment of psoriasis. It is very essential to maintain the proper pH balance in the chemistry of psoriasis patients. Diet assists in the maintenance of a proper acid-base homeostasis of the chemical activity in the body according to Pagano (71). He suggests that psoriatic patients should be on the basic (alkaline) side than the acidic side as nature demands. The body chemistry that is leaning more towards the alkaline is more resistant to all kinds of disease (71). Furthermore, he recommends eating alkaline-forming foods such as raw carrot, celery, beets, parsley, romaine, lettuce, and spinach juice extracts, and avoids acid-forming foods such as strawberries, citrus fruits, citrus juices, and avocados (73-75). He mentions that a person’s blood should be always on the slight alkaline side (pH 7.3-7.5) to maintain the ideal health and immunity (71). Therefore, psoriatic patients should be awar e of their diet to maintain alkalinity in the blood and body chemistry to have a better resistance to disease and strengthen their immunity. Psoriasis is a very serious disease when it comes to the personal well being of a person who suffers from it. Knowing the possible stressors of psoriasis can help psoriatic patient treat its symptoms before its onset and exacerbation. Though the exact cause of psoriasis is unknown, bacterial or viral infections, toxic drugs, and psychosocial distress are few possible stressors of psoriasis. These stressors can cause the skin cell to behave erratically causing itchiness and inflammation of the skin. Many clinical studies have suggested that psychosocial stress can cause the exacerbation of psoriasis. Furthermore, a good mental attitude towards the disease is important to look at because they need a strong support group as they live their life daily with all the struggles they experience with the disease. In addition, different types of treatments such as topical agents (salicylic acid, vitamin D compounds, and corticosteroids), phototherapy (ultraviolet light), and diet are used to tr eat itching, inflammation, and other symptoms of psoriasis. Diet plays a very important role in alleviating the symptoms of psoriasis as long as the body chemical atmosphere is within the alkaline side for it aids a person from being resistant to diseases and increase its immunity. A deeper understanding of the stressors of psoriasis can help many people to win their battle with psoriasis. Al’ Abadie, M.
