Lead is a toxic metal that is harmful to human health; there is NO safe level for lead exposure. The degree of exposure depends on the concentration of lead, route of exposure (air, water, and food), current medical condition, and age. It has been estimated that up to 20 % of the total lead exposure in children can be attributed to a waterborne route, i.e., consuming contaminated water. In addition, infants, fetuses, and young children are particularly vulnerable to lead poisoning. This is…

Environmental Working Group (EWG) expressed their concerns about contaminants in drinking water that have not been regulated in Safe Water Drinking Act (1974) because the list of regulated chemicals hasn’t been updated since 1996; the concentration of the contaminants given by EPA should have been lower for some substances. Based on the study of EWG, over half of the unique contaminants were found in water facilities, and these contaminants are found hazardous for human health. The risk EWG is…

source specific air pollution, such as from factories and automobiles. The Clean Air Act of 1970 granted real power to the federal government instead of the states. The Environmental Protection Agency (EPA) was to set the standards and to focus on major polluting chemicals. Auto emissions were to be reduced by 90%. The 1970 Act required states to enforce the Clean Air Act. The Clean Air Act was amended in 1977 and last amended in 1990. It addressed issues like acid rain, toxic pollutants and…

EPA and CERCLA into a proactive agency and policy. This can be achieved by maintaining oversight on known hazardous waste sites, while regulating and preventing the occurrence of new hazardous waste sites. This approach can be facilitated in several different ways. First would be too reinstate the Superfund tax as a financial preventative measure to specific “risky” industries. When CERCLA was enacted, remedial costs were collected through taxation of chemical…

of China 's cities, pollution is so bad that the citizens have to stop for oxygen break at an oxygen station deployed in the city. In fact, according to China 's organization (Ministry of Environmental Protection), the air in some cities in the country has met the Air standards making the country an environmental crisis. In addition, because of the rising Air pollution in China, more than 10 million cans of oxygen cans were sold last year (Hills, Suzannah). Oxygen in a can is just one example of…

companies are claiming “that their [newer paint] is susceptible to marring by acid rain(New York Times)”, meaning that many people will have to start paying out hundreds to the repair of their car paint due to acid rain damage. To prevent health, environmental, and weather the majority sources must be minimized. What the graph, “Human Sources of Nitrous Oxide”, by suggests the intergovernmental panel on Climate change is the agriculture is the number one air polluter or nitrous oxides by…

We believe the following strategies, each with its unique set of challenges, would help Mihocko Inc. respond to the need for compliance with the proposed Environmental Protection Agency’s (EPA) emissions limits. The first strategy would be to adjust its product mix. Mihocko produces five products, one at a time, throughout the year. Using data provided, Mihocko can determine an optimal production combination function based on potential sales, variable costs, particulate emissions, revenue…

condition. From an aesthetic perspective, painting the window would be preferable, however, in many cases it may be better to leave the fragile paint layer unrestored. It must be noted that if the paint were to be reapplied, it might provide some added protection to the potassium oxide…

contaminated. This can also affect the society because alerts will go out telling people that it's not safe to go outside. It's not just factors that are polluting the air, it's us humans that are driving our vehicles all day every day. And the economical state of how this affects the world. Air pollution is caused by fossil fuels being burned in those factors and the gases are released into the atmosphere and that's why you see in some cities like…

Over the past 40 years, the Clean Air Act and the Environmental Protection Agency have made several advances in helping reduce air pollution and creating a better nation. Recently, congress has attacked the Environmental Protection Agency, essential tying their hands, for personal gains. In The Clean Air Act, Congress found that the pollution caused by rapidly evolving Cities, industrial development, and motor vehichle use were creating a danger to public health and agriculture. The primary…
