Pollution

Environmental pollution is the release of environmental contaminents, generally created and causes by human activities.Carbon monoxide, sulfur dioxide and nitrogen oxides produced by industry and motor vehicles are common air pollutants.Pollutants can cause disease, including cancer, lupus, immune diseases, allergies, and asthma.Some sources of pollution, such as nuclear power plants or oil tankers, can produce widespread and potentially hazardous releases when accidents occur. Adverse air quality can kill many organisms including humans.Ozone pollution can cause respiratory disease, cardiovascular disease, throat inflammation, chest pain, and congestion.Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by untreated sewage in developing countries.Oil spills can cause skin irritations and rashes.Noise pollution induces hearing loss, high blood pressure, stress, and sleep disturbance.So we have to care for our environment through over the world not only for us also for others also. Which has created my GOd,just only for our benefit we cant destroy it like this. So we have to keep our environment as natural and normal as it is.

Environmental impact Assessment

An Environmental Impact Assessment (EIA) is an assessment of the likely human environmental health impact, risk to ecological health, and changes to nature's services that a project may have.The principal phenomena or pathways of impact are: soil contamination impacts, air pollution impacts, noise health effects, ecology impacts including endangered species assessment, geological hazards assessment and water pollution impacts..

Environmental quality

Environmental quality is a set of properties and characteristics of the environment, either generalized or local, as they impinge on human beings and other organisms.
It is a general term which have a different characteristics that relate to the natural environment as well as the built environment, such as air and water purity or pollution, noise and the potential effects which such characteristics may have on physical and mental health caused by human activities.
