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.
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 atmosphere.
v. t. e. Global dimming is a decline in the amount of sunlight reaching the Earth's surface. [2] [3] It is caused by atmospheric particulate matter, predominantly sulfate aerosols, which are components of air pollution. [4] Global dimming was observed soon after the first systematic measurements of solar irradiance began in the 1950s.
A complex mix of commercial signs make up the view's background. Visual pollution refers to the visible deterioration and negative aesthetic quality of the natural and human-made landscapes around people and to the study of secondary impacts of manmade interventions. [1] It also refers to the impacts pollution has in impairing the quality of ...
Human activities — for instance, the way we heat our homes, power our air conditioners, fuel our cars and produce our food — all contribute to greenhouse gas emissions, which causes 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]
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 ...
e. 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.
