A conventional pollutant is a term used in the USA to describe a water pollutant that is amenable to treatment by a municipal sewage treatment plant. A basic list of conventional pollutants is defined in the U.S. Clean Water Act. [1] The list has been amended in regulations issued by the Environmental Protection Agency: biochemical oxygen ...
It is listed as a conventional pollutant in the U.S. Clean Water Act. [1] Total dissolved solids is another parameter acquired through a separate analysis which is also used to determine water quality based on the total substances that are fully dissolved within the water, rather than undissolved suspended particles.
A Suspect List Exchange [38] (SLE) has been created to allow sharing of the many potential contaminants of emerging concern. The list contains more than 100,000 chemicals. Table 1 is a summary of emerging contaminants currently listed on one EPA website and a review article. Detailed use and health risk of commonly identified CECs are listed in ...

Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, and the individual's health status and genetics. [103] The most common sources of air pollution include particulates and ozone (often from burning fossil fuels), [123] nitrogen dioxide, and sulfur dioxide. Children aged less ...
These sections require the EPA "(1) to list widespread air pollutants that reasonably may be expected to endanger public health or welfare; (2) to issue air quality criteria for them that assess the latest available scientific information on nature and effects of ambient exposure to them; (3) to set primary NAAQS to protect human health with ...
Particulate pollution can occur directly or indirectly from a number of sources including, but not limited to: agriculture, automobiles, construction, forest fires, chemical pollutants, and power plants. [30] Exposure to particulates of any size and composition may occur acutely over a short duration, or chronically over a long duration. [31]
