management studies‚ to consulting on the environmental effects of various construction projects. On a larger scale‚ environmental engineers also work on global issues such as the issues of acid rain‚ global warming‚ air and water pollution‚ and ozone depletion. The type of work you can do as an environmental engineer is countless. Environmental engineers can be designers‚ researches‚ planners‚ an operator of pollution control facilities‚ a professor‚ a government regulatory agency official‚ or be involved

The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems. A substance in the air that can be harmful to humans and the environment is known as an air pollutant. Pollutants can be in the form

AIR POLLUTION AND CLIMATIC CHANGES Introduction: Air pollution is actually the addition of any harmful substances to the atmosphere‚ which causes the damaging of the environment‚ human health and the quality of life. Air pollution has been a serious problem throughout the history. This can have series effect on the health of human beings. Every day‚ the average person inhales about 20‚000 liters of air. Every time when we breathe in we inhale dangerous substances. These dangerous substances can

Ground-level ozone: Chemical reactions involving air pollutants create a poisonous gas ozone (O3). Gas Ozone can affect people’s health and can damage vegetation types and some animal life too. Particulate matter: Air pollutants can be in the form of particulate matter which can be very harmful to our health
