Extreme smog events were experienced by the cities of Los Angeles and Donora, Pennsylvania in the late s, serving as another public reminder. Thermal pollutionis a temperature change in natural water bodies caused by human influence, such as use of water as coolant in a power plant.
A massive volcanic eruption has the potential of discharging huge swathe of dust into the atmosphere to an extent of obstructing sunlight from reaching the earth surface. Some of the biggest wildfires have emitted smoke that drifted several miles across bordering cities and countries.
Sources and causes Play media Air pollution produced by ships may alter clouds, affecting global temperatures. Wildlife can also die from exposure. However, globally human-made pollutants from combustion, construction, mining, agriculture and warfare are increasingly significant in the air pollution equation.
An estimated million Indians have no access to a proper toilet,   Over ten million people in India fell ill with waterborne illnesses inand 1, people died, most of them children. Though extreme care is practiced in that industry, the potential for disaster suggested by incidents such as those at Three Mile Island and Chernobyl pose a lingering specter of public mistrust.
Some people can become sensitized to biological or chemical pollutants after repeated or high level exposures. High temperature and humidity levels can also increase concentrations of some pollutants.
Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of aerosols. Organic pollution of watercourses can deplete oxygen levels and reduce species diversity.
In a typical industrial plant, for instance, it is easy to notice the long chimneys or smokestacks erected into the airemitting large amounts of fumes and smoke from it.
Protective measures to ensure children's health are being taken in cities such as New DelhiIndia where buses now use compressed natural gas to help eliminate the "pea-soup" smog. There are a number of effects of this: Environmental Protection Agency monitors 80 different contaminants that may affect drinking water.
Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggravated or worsened. A few problem areas such as the Doon Valley - an ecologically sensitive area, the National Capital Region NCR which is suffering from air and water pollution as well as congestion, Damodar River Basin which is very rich in natural resources and yet has extensive environmental degradation and Tapi estuary which represents the problems in the coastal region both for water and land development, have been selected for carrying out such studies.
Toxic substances from litter also accumulates in fish, exposing the people and animals further up the food chain to these pollutants. Worker productivity A number of studies show that pollution has an adverse effect on the productivity of both indoor and outdoor workers. People, especially children, can be seriously injured by a broken bottle or a rusty piece of discarded metal.
In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control.Because people spend a lot of time indoors, the quality of the air indoors can affect their health.
Remodeling or renovating an existing home has the potential to release indoor pollutants. The Ministry of Environment & Forests (MoEF) is the nodal agency in the administrative structure of the Central Government for the planning, promotion, co-ordination and overseeing the implementation of India's environmental and forestry policies and programmes.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light.
Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring cheri197.comion is often classed as point source or nonpoint source pollution.
