Ways to Control Water Pollution With major water reservoirs drying up in the Southeast‚ the United States government is projecting that within the next five years over 38 of its states will face serious water shortages. And of the water that will remain‚ today’s serious issues will influence our future unless we find successful ways to control water pollutionor it will eventually disrupt life on our planet as we know if we do not. The sources of water pollution are varied– ranging widely from

CCCH9008 Noise Pollution and Control in HK Two important characteristics of sound or noise Frequency of Sound Sound is the quickly varying pressure wave travelling through a medium. When sound travels through air‚ the atmospheric pressure varies periodically. The number of pressure variations per second is called the frequency of sound‚ and is measured in Hertz (Hz) - cycles per second. Loudness A loud noise usually has a larger pressure variation and a weak one has smaller pressure variation

single source of air pollution Today’s on-road vehicles produce over a third of the carbon monoxide and nitrogen oxides in our atmosphere and over twenty percent of the global warming pollution. This air pollution carries significant risks for human health and the environment. Through clean vehicle and fuel technologies‚ we can significantly reduce air pollution from our cars and trucks‚ while cutting projected U.S. oil use in half within the next 20 years. Cars and trucks produce air pollution throughout

Strict gun control legislation may benefit public safety. In 2013‚ after the deadly Sandy Hook Elementary shooting‚ President Obama released a three-pronged plan to reduce gun violence in the United States. The plan would improve a potential firearm buyer’s background investigation‚ prohibit military-type assault weapons and high-capacity magazines‚ enhance penalties for illegal gun trafficking and bar straw purchasers to buy guns for unauthorized people or uses.

Environmental pollution‚ problems and control measures A. Introduction and definition of environmental pollution – We know that‚ a living organism cannot live by itself. Organisms interact among themselves. Hence‚ all organisms‚ such as plants‚ animals and human beings‚ as well as the physical surroundings with whom we interact‚ form a part of our environment. All these constituents of the environment are dependent upon each other. Thus‚ they maintain a balance in nature. As we are the only organisms

Types‚ Effects‚ and Controls of Air Pollution Air pollution depending upon which source you use is broken down in a couple of ways. No matter how you look at it though‚ air pollution is still air pollution and it is both harmful to humans and the environment. One source breaks air pollution down into two categories or seven primary and two secondary pollutant types (Wright & Boorse‚ 2008‚ p. 487). The primary pollutants can more easily be broken down into four types of pollution which are based upon

POLLUTION FROM DIESEL ENGINES AND ITS CONTROL Diesel engines and gasoline engines are the most widely used primary sources of power in automobiles and the sheer number of them makes the issue of emissions from these engines an important one. Table 1 gives a comparison of the amounts of different pollutants in the exhaust of diesel and petrol engines. FORMATION OF NOX AND CONTROL METHODS: The main source of NOx in diesel engine emissions is the oxidation of the nitrogen in the air at the high temperatures

Pollution control in recycling of lead batteries Introduction: Lead is one the most successfully recycled material in the world. Over the years lead recycling has greatly matured as a result over half of the lead produced and used each year throughout the world has been used before in other products. Today over 80% of the lead is used in the making of lead-acid batteries which are theoretically speaking 100% recyclable. Lead recycling however has one critical problem‚ lead and the many of the
