Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Air pollution is also a major contributor to surface water pollution. The type of pollutants in the air emitted by industrial facilities, motor vehicles, and agricultural bio-waste released to the atmosphere affect the quality of marine and fresh water bodies, thus affecting marine life, plants, animals, and ultimately human survival.
Particulate pollution. Particulate pollution is pollution of an environment that consists of particles suspended in some medium. There are three primary forms: atmospheric particulate matter, [1] marine debris, [2] and space debris. [3] Some particles are released directly from a specific source, while others form in chemical reactions in the ...
Environmental geology, like hydrogeology, is an applied science concerned with the practical application of the principles of geology in the solving of environmental problems created by man. It is a multidisciplinary field that is closely related to engineering geology and, to a lesser extent, to environmental geography. [1]
Nonpoint source ( NPS) pollution refers to diffuse contamination (or pollution) of water or air that does not originate from a single discrete source. This type of pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. It is in contrast to point source pollution which results from a single source.
Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [1] [2] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [3] Plastics are inexpensive and durable ...
Doug O'Malley, director of Environment New Jersey, said more than 100 cities across the U.S. have banned or restricted gas-powered leaf blowers, which he called a major source of pollution.
The air-quality monitor system ( IMECA) is the tool used by the Mexican Authorities to measure air quality. A total of 8 system monitors, located all around Mexico City measure the levels for the 6 main pollutants that are found in the atmosphere of the city. The measured pollutants are: O3, PM10, PM2.5, CO, NO2, SO2.
