Effects Of Chemical Leakage On Humans And The Environment

To prevent water pollution, chemicals themselves also have to be regulated more strictly. In Australia, only chemicals on the NICNAS Australian Inventory of Chemical Substances (AICS) can be imported or manufactured for industrial use("Chemicals…”).. Moreover, new chemicals have to be tested by four major Commonwealth schemes of registration and assessment ("Chemicals…”). On the other hand, the Environmental Protection Agency (E.P.A) that acts as our chemical regulators has mandated safety testing for only a small percentage of the 85,000 industrial chemicals available for use today (Urbina,

Water contamination is vastly becoming an alarming issue across the world. We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that we tap for drinking water are being overdrawn or tainted with pollution (www.nrdc.org). Clean and plentiful water is the cornerstone of prosperous communities. Yet as we enter the 21st century, swelling demand and changing climate patterns are

There are three main mechanisms by which the chemical composition of groundwater, which is our natural source of drinking water, may be changed: by natural processes, by man's waste-disposal practices such as those for sanitary wastes, liquid industrial wastes, solid wastes, and radioactive wastes, and by spills, leaks, and agricultural activities and other sources unrelated to disposal. The degree of risk posed by contaminants varies according to many factors. These include the volume and toxicity of the contaminant, its concentration in the aquifer, its persistence in the environment, and the degree of human and environmental exposure to the contaminant. In addition, the number of persons affected, or likely to be affected, over time and the percentage of available groundwater both locally and regionally should be taken into consideration. If the contaminants in the groundwater exceed the standards set for drinking water by the federal government, for example, then the water is hazardous for the use for which it was designated under the standards. These standards include, however, only a limited number of chemicals, and thus they do not necessarily protect humans or the environment against either the short-term or the long-term effects of every contaminant that might be found in

Chemicals harm the growth of plants and animals, chemicals can lead animals to death. Many of the water animals

This analysis of case studies from Los Alamos National Laboratory, and the case study to predict the effects of pesticides on aquatic systems and the waterfowl that uses them. Comparing the two processes of these case studies, along with analysis of the assessments. Describing the case study on the effects of pesticides in aquatic ecosystem, the risk assessment correlated to observed field studies and evaluate the importance of this type of correlation in general for all risk assessment efforts. Breaking down the ecological and social

More often than not, the society worries and frets over the impending doom posed by pollution on our own species, but the millions of other organisms feel the impact almost more than the creators of the issues themselves. In the Gulf Oil Spill of 2010, 3.19 million barrels were released into the ocean after a break in an Exxon oil pipe, and is rightfully called the worst oil spill in history. Cleaning up spilled oil is difficult in itself, but when thousands of metric tons of it spreads across the Gulf of Mexico, the job is much more substantial. Methods to remove and avoid spread as much as possible exist, but are never completely effective, especially when chemical dispersants are nearly impossible to contain. The death rate of dolphins in the area tripled, large coral reefs showed sign of immediate tissue damage, and aquatic birds became slick and unable to fly, causing many to starve. The oil spill covered in total nearly 1000 miles of ocean, and this is only example of the many that have occurred in the past twenty years (Frost, Emily). Air pollution is now the most common type of pollution, as our constant use of automobiles seems never ending. A deluge of acid rain has decimated entire forest ecosystems, and in cities such as Beijing and Singapore, the smog is so thick, many must wear masks to breathe comfortably. Countless examples of our wrong-doings on the

It is easy person to point their finger at big industrial and chemical plants and blame them for the cause of so much pollution in our water. When taking a closer look, those same people pointing the finger are equally contributing to the pollution of our water supply and are also to blame. This person could be a friend, family member, classmate, or even you. Even if people do not think that they have a part in this, most do. A variety of data has shown traces of pharmaceuticals used by every day humans in our water. As well as pharmaceuticals there is a presence of chemical contaminants, mainly pesticides that are causing harm to our environment and wildlife. Even humans can be affected by such contamination in the water supply, and

Chemical dispersants pull apart oil particles that are suspended in water, reducing the oil slick to droplets that can be degraded by naturally occurring bacteria. When the chemicals are applied, dispersed oil is greatly less toxic. However, because the chemical properties of leaked oil will change over time, dispersants may lose their ability to break apart the oil. There are also concerns about the dispersants themselves , which can also be toxic and as a result it could be damaging the

Chemical compounds that are commonly heard of today such as BPA (bisphenol A) is a toxic compound found mostly in plastics and then are dumped into oceans that begin to poison our waters where humans, but mostly animals drink and ingest through the nose. (Barry, 2009). Another toxic chemical such as PVC (polyvinyl chloride) can be harmful to animals on land and in sea can leak from plastic water bottles. This intoxicates the water where animals drink and swim, causing them to grow ill and maybe even die. (Breast Cancer Fund, http://www.breastcancerfund.org/clear-science/environmental-breast-cancer-links/plastics/?referrer=https://www.google.com/) By eliminating much of the plastics consumption that ends up in the oceans, we will prevent animals and humans also from being affected by the harmful chemicals being produced.

By using these chemical pesticides on the plants, it causes dissolved oxygen depletion in the water, phytotoxicity to the plants, and poisons the animals (Environmental Effects of Pesticides). From the greediness of crop cultivation, millions of species of fish will disappear. These pesticides do not only get into the ocean by spraying it, they get into the ocean when small particles fly over from the drift of the wind. This is especially common at beaches where people spray chemicals on the grasses nearby to prevent other people from being bitten by insects. Not only do pesticides affect the oceans, but the plants as well. These pesticides cause phytotoxicity refers to plant injury. By using these chemical pesticides, it damages the plants, especially those genetically similar to weeds. They can progressively result in mutations little by little until eventually there will be a period of time where the plants now will be very different. Even though this is what is happening now, Hawthorne, an author from 200 years ago, also thought that scientists were being evil. In “Rappaccini’s Daughter,” when it states “Dost thou deem it misery to be endowed with marvellous gifts, which no power nor strength could avail an enemy?...Wouldst thou, then, have preferred the

Offshore oil drilling is a controversial topic because when oil spills, it does extensive amounts of damage to the environment. Countries capable of mining oil in the ocean reap the economic benefits in addition to reducing their dependency on external oil. While it is uncontroversial that offshore drilling is a massive boon for those countries, the environmental consequences of a spill also affect the economic welfare of nearby residents. Oil contaminates animals through a process called biomagnification, where chemicals progressively become more detrimental to the animals the higher they are on the food chain. When oil spills into the ocean, it impairs the growth of native species and deteriorates the ecosystem. As a result, the livelihood of people in the tourist industry, fisherman, and shrimpers is crippled and may take decades to recover.

“A common misconception is that all man-made chemicals are harmful, and all natural chemicals are good for us. However, many natural chemicals are just as harmful to human health, if not more so” (Lorch). Dorea Reeser provides a different perspective to counteract the harmful effects of manmade chemicals. Dorea Reeser upholds a Ph. D. in environmental chemistry at the University of Toronto. She researches and studies the chemical reactions at water surfaces, and how the chemical and physical properties influence these reactions and the release of important trace gases into the troposphere.

The largest source of contamination is runoff from land. Toxic runoff can be sewage, rainwater flowing over exposed topsoil, flooding or agricultural runoff. Rain can cause runoff of chemicals or waste that can seep into creeks, rivers and other waterways that lead to the ocean. Some of the chemicals found could be antibiotics or waste from animals, pesticides from crops or from pollutants, originating in the air, which have settled on land and washed away. Unless a solution to pollution runoff is found, this type of contamination will continue indefinitely and contribute to the deterioration of the ecosystem in the

The purpose of this report is to propose a solution to the problem of reduced drinking water quality due to chemical pollution. Some bodies of water in the United States are becoming polluted from chemicals and restrictions are needed to protect drinking water quality.

Although the state of America’s water infrastructure is of great concern, the types of chemicals found in America’s tap water are equally as frightening. The passage of the Water Act in 1972 prevents the direct dumping of hazardous chemicals directly into waterways, and helps regulate quality standards of water. However, the Clean Water Act is has no jurisdiction on regulating indirect dumping of chemicals that integrates into water supplies. Pesticides and prescription drugs are the greatest cause for concern of indirect containments in America’s water supply (Olsen). An abundance of the harmful chemicals found in liquefied animals feces, used in large dairy states, have percolated into drinking wells that have caused serious infections (Duhigg). However, more harmful containments are infiltrating water supplies. Such containments include
