AIR POLLUTION [pic] Introduction The earth’s atmosphere‚ at or near sea level‚ consists approximately of 78 percent nitrogen‚ 21 percent oxygen and 1 percent other gases. If it were possible to remain in this state‚ 100 percent clean air would result. However‚ many varied sources allow other gases and particulates to mix with the clean air‚ causing our atmosphere to become unclean or polluted. Some of these pollutants are visible while others are invisible‚ with each

Introduction to Air Pollution Air pollution is the presence of foreign substances in the atmosphere‚ emitted by industries and motor vehicles that cause damage to living organisms. Air pollution characteristics Air pollution characteristics in a particular region are influenced by: The type and amount of pollutant and their source of emission. The topographical and meteorological conditions affecting dispersion‚ concentration and transboundary transport of pollutants. The type of technology

The industry thus contributes very significantly to the current unsustainable development path of the global economy. This paper has two purposes. First‚ it attempts to identify the principal ways in which construction contributes to environmental stress‚ and to quantify the contribution of construction where possible. Secondly‚ it considers the means available to reduce these

Eutrophication occurs when a body of water enriched with excess nutrients‚ nitrogen and phosphorus from dead plant material and waste. Nitrogen pollution largely derived from agricultural fertilizers and emissions from the combustion of fossil fuels. Phosphorus pollution comes from wastewater treatment and detergents. These elements

Marine Habitat Destruction Anita Rouse SCI/275 07/24/2010 Jean-Paul Simjouw‚ PhD Marine habitats are in grave danger due to humans and Mother Nature. Hurricanes‚ typhoons‚ storm surges‚ and tsunamis are factors in which contributes to the destruction of marine habitats and are caused by Mother Nature. Human’s destruction to these habitats is much worse due to the fact that Mother Nature’s destruction is mostly temporary‚ while humans leave more of a lasting footprint on the habitats because
