- the action or process of making land, water, air, etc., dirty and not safe or suitable to use- substances that make land, water, air, etc., dirty and not safe or suitable to use

- Air pollutants can lead to respiratory health problems such as asthma, chronic bronchitis and decreased lung function.- Drinking contaminated water may lead to stomach and other digestive problems.- Pollutants such as mercury can accumulate in fish and seafood and can lead to serious health problems, especially for vulnerable populations such as children or pregnant women.- Pollutants in the soil, such as contamination by heavy metals, toxins or lead, can lead to serious health problems, including cancer and developmental problems in children.

- Most air toxics originate from human-made sources, including mobile sources (e.g., cars, trucks, buses) and stationary sources (e.g., factories, refineries, power plants), as well as indoor sources (e.g., building materials and activities such as cleaning).- "Major" sources are defined as sources that emit 10 tons per year of any of the listed toxic air pollutants, or 25 tons per year of a mixture of air toxics. These sources may release air toxics from equipment leaks, when materials are transferred from one location to another, or during discharge through emission stacks or vents- "Area" sources consist of smaller-size facilities that release lesser quantities of toxic pollutants into the air. Area sources are defined as sources that emit less than 10 tons per year of a single air toxic, or less than 25 tons per year of a combination of air toxics. Though emissions from individual area sources are often relatively small, collectively their emissions can be of concern - particularly where large numbers of sources are located in heavily populated areas.
