A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. These can be both naturally forming or anthropogenic in origin. Pollutants result in environmental pollution or become public health concerns when they reach a concentration high enough to have significant negative impacts.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance or energy. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Environmental health is the branch of public health concerned with all aspects of the natural and built environment affecting human health. In order to effectively control factors that may affect health, the requirements that must be met in order to create a healthy environment must be determined. The major sub-disciplines of environmental health are environmental science, toxicology, environmental epidemiology, and environmental and occupational medicine.
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. It often disperses downwind in a pattern called an exhaust plume.
Environmental racism, ecological racism, or ecological apartheid is a form of institutional racism leading to landfills, incinerators, and hazardous waste disposal being disproportionately placed in communities of color. Internationally, it is also associated with extractivism, which places the environmental burdens of mining, oil extraction, and industrial agriculture upon indigenous peoples and poorer nations largely inhabited by people of color.
Cancer Alley is the regional nickname given to an 85-mile (137 km) stretch of land along the Mississippi River between Baton Rouge and New Orleans, in the River Parishes of Louisiana, which contains over 200 petrochemical plants and refineries. This area accounts for 25% of the petrochemical production in the United States. Environmentalists consider the region a sacrifice zone where rates of cancer caused by air pollution exceed the federal government's own limits of acceptable risk. Others have referred to the same region as "Death Alley".
The Toxic Substances Control Act (TSCA) is a United States law, passed by the 94th United States Congress in 1976 and administered by the United States Environmental Protection Agency (EPA), that regulates chemicals not regulated by other U.S. federal statutes, including chemicals already in commerce and the introduction of new chemicals. When the TSCA was put into place, all existing chemicals were considered to be safe for use and subsequently grandfathered in. Its three main objectives are to assess and regulate new commercial chemicals before they enter the market, to regulate chemicals already existing in 1976 that posed an "unreasonable risk of injury to health or the environment", as for example PCBs, lead, mercury and radon, and to regulate these chemicals' distribution and use.
Heavy industry is an industry that involves one or more characteristics such as large and heavy products; large and heavy equipment and facilities ; or complex or numerous processes. Because of those factors, heavy industry involves higher capital intensity than light industry does, and is also often more heavily cyclical in investment and employment.
Environmental justice or eco-justice, is a social movement to address environmental injustice, which occurs when poor or marginalized communities are harmed by hazardous waste, resource extraction, and other land uses from which they do not benefit. The movement has generated hundreds of studies showing that exposure to environmental harm is inequitably distributed.
Altgeld Gardens Homes is a Chicago Housing Authority (CHA) public housing project on the far south side of Chicago, Illinois, United States, on the border of Chicago and Riverdale, Illinois. The residents are 97% African-American according to the 2000 United States Census. Built between 1944 and 1945 with 1,498 units, the development consists primarily of two-story row houses spread over 190 acres (0.77 km2).
Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological agents that alters the natural features of the atmosphere. There are many different types of air pollutants, such as gases, particulates, and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and crops, and may damage the natural environment or built environment. Air pollution can be caused by both human activities and natural phenomena.
Environmental issues in Canada include impacts of climate change, air and water pollution, mining, logging, and the degradation of natural habitats. As one of the world's significant emitters of greenhouse gasses, Canada has the potential to make contributions to curbing climate change with its environmental policies and conservation efforts.
Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere, causing harm or discomfort to humans or other living organisms, or damaging ecosystems. Air pollution can cause health problems including, but not limited to, infections, behavioral changes, cancer, organ failure, and premature death. These health effects are not equally distributed across the U.S. population; there are demographic disparities by race, ethnicity, socioeconomic status, and education. Air pollution can derive from natural sources, or anthropogenic sources. Anthropogenic air pollution has affected the United States since the beginning of the Industrial Revolution.
In epidemiology, environmental diseases are diseases that can be directly attributed to environmental factors. Apart from the true monogenic genetic disorders, which are rare, environment is a major determinant of the development of disease. Diet, exposure to toxins, pathogens, radiation, and chemicals found in almost all personal care products and household cleaners, stress, racism, and physical and mental abuse are causes of a large segment of non-hereditary disease. If a disease process is concluded to be the result of a combination of genetic and environmental factor influences, its etiological origin can be referred to as having a multifactorial pattern.
The Kettleman Hills Hazardous Waste Facility is a large hazardous waste and municipal solid waste disposal facility, operated by Waste Management, Inc. The landfill is located at 35.9624°N 120.0102°W, 3.5 mi (5.6 km) southwest of Kettleman City on State Route 41 in the western San Joaquin Valley, Kings County, California.
Communities for a Better Environment (CBE), previously known as Citizens for a Better Environment, is a policy-focused non-profit organization started in 1971 by Marc Anderson and David Come in Chicago, Illinois. In the late 1970s and early 1980s, CBE expanded to California, Wisconsin, and Minnesota. CBE established itself in San Francisco in 1978 and expanded to Los Angeles in 1982. Today, CBE is based in Oakland, CA and Huntington Park, CA, effecting positive change in communities throughout California, including Richmond, East Oakland, Vernon, Huntington Park, Boyle Heights, Pacoima, Wilmington, and SE Los Angeles. CBE was the first environmental organization to practice door-to-door canvassing by directly involving community members. In 1980, CBE won the United States Supreme Court decision on Village of Schaumburg v. Citizens for a Better Environment 444 U.S. 620, protecting the 1st and 14th Amendment Rights of door-to-door activists with CBE and countless other public interest organizations. CBE's early combination of grassroots organizing with research and legal work provided the innovative edge needed to challenge large-scale industries and refineries, and government policies.
Toxic hotspots are locations where emissions from specific sources such as water or air pollution may expose local populations to elevated health risks, such as cancer. These emissions contribute to cumulative health risks of emissions from other sources nearby. Urban, highly populated areas around pollutant emitters such as old factories and waste storage sites are often toxic hotspots.
A sacrifice zone or sacrifice area is a geographic area that has been permanently changed by heavy environmental alterations or economic disinvestment, often through locally unwanted land use (LULU). Commentators including Chris Hedges, Joe Sacco, and Steve Lerner have argued that corporate business practices contribute to producing sacrifice zones. A 2022 report by the United Nations highlighted that millions of people globally are in pollution sacrifice zones, particularly in zones used for heavy industry and mining.
Lara J. Cushing is an assistant professor of environmental health sciences and holds the Jonathan and Karin Fielding Presidential Chair in Health Equity at the Fielding School of Public Health of the University of California, Los Angeles (UCLA).
Environmental racism is a form of institutional racism, in which people of colour bear a disproportionate burden of environmental harms, such as pollution from hazardous waste disposal and the effects of natural disasters. Environmental racism exposes Native Americans, African Americans, Asian Americans, Pacific Islanders, and Hispanic populations to physical health hazards and may negatively impact mental health. It creates disparities in many different spheres of life, such as transportation, housing, and economic opportunity.
