Water and air pollution have altered the course of the earth’s history. The emissions inventory for New Jersey was briefly reviewed and revised by NJDEP before being finalized by USEPA. Air pollution comes from many different sources: stationary sources such as factories, power plants, and smelters and smaller sources such as dry cleaners and degreasing operations; mobile sources such as cars, buses, planes, trucks, and trains; and naturally occurring sources such as windblown dust, and volcanic eruptions, all contribute to air pollution. A source category is a specific industry sector or group of similar emitting sources. Residential heating, which is the primary cause of particulate matter (PM) emissions, contributes to the problem through the use of low-quality fuels, such as coal. Point sources are usually associated with manufacturing and industrial processes, such as boilers, spray booths or degreasers.

Different regions have different air pollution issues. With the continual improvement in our quality of life, indoor air quality has become an important area of concern in the twenty-first century. Major point sources include power plants; refineries; municipal waste incinerators; toxic waste transfer, storage and disposal facilities (TSDFs); TRI sources (facilities that are required to report their emissions under the Toxic Release Inventory program); and other sources that must report emissions under other state and federal programs. For the 1999 NATA, USEPA defines them in the following way: Major Point Sources: A point source is a stationary facility or process that emits a significant amount of air pollution during manufacturing, power generation, heating, incineration, or other such activity. Users new to Google Earth will notice that there are "layers" of information provided in the Google Earth software that are independent of this emissions files. A to Z, 1990 "This publication represents the views and expert opinions of an IARC Working Group on the Evaluation of Carcinogenic Risk to Humans, which met in Lyon, 8-15 October 2013."

This chapter discusses the major sources of the main primary air pollutants including the contribution of the different sources to total emissions of a range of pollutants in the European Union (EU), the USA and selected urban areas in the UK. Second are stationary sources such as power plants, oil refineries, industrial facilities, and factories. In NATA, USEPA refers to this category as "Area and Other Sources," and includes small industrial sources that fall below the "major source" threshold. Air quality 1.1 Sources of air pollution Air pollutants can come from both natural and anthropogenic sources, but anthropogenic air pollutants dominate the atmosphere of areas primarily undergoing industrialization. Dusting activities are quite common sources of indoor air pollution. PVC standards were developed for both major and area sources.
