One of the important aims of environmental quality studies is to investigate the present of anthropogenic compounds such as organic micropollutants on the ecosystem, in order to minimize or prevent adverse effects. Organic contaminants such as Polycyclic Aromatic Hydrocarbon (PAHs) may enter the water environment from many different sources including river runoff, atmospheric precipitation, sewage outfalls and maritime transport (Zhou J.L, and Maskaoui K, 2001). The PAHs are one of the most...
Emissions from heavy-duty vehicles contribute significantly to a number of serious air pollution problems. Ground-level ozone, particulate matter (PM), nitrogen oxides (NOx), sulphur oxides (SOx),and volatile organic compounds (VOCs ) adversely affect public health, contributing to premature mortality, aggravation of respiratory and cardiovascular disease, decreases in lung function and increased respiratory symptoms changes to lung tissues and structures, altered respiratory defense...
Like most natural resources, potable water is under threat of being exhausted due to over-consumption. And like most natural resources, once depleted, regeneration of the ground water and surface water will take hundreds of years. At the present rate of consumption every opportunity needs to be utilized to conserve our sources of water and create legislation that will encourage judicious use of water. Governmental agencies and private enterprise should mobilize their resources to build proper...
A permanent settlement, which is relatively large, as compared to a town or a village and has a population is called as a city. Cities face a great challenge in terms of resource consumption and climate change. Urban areas have high energy and resource intensive lifestyle and consumption pattern. As a consequence, cities and the urban areas today contribute to more than 80% of the greenhouse gas emissions globally. Thus, it's imperative to design and restructure the cities in an eco-friendly...
On December 3, 1984. In the city of Bhopal, a cloud of toxic gases escaped from an American pesticide plant, killing and injuring thousands of people. When the noxious clouds cleared, the worst industrial disaster in history had taken place. Now, Dominique Lapierre in her book "Five Past Midnight" brings the hundreds of characters, conflicts, and adventures together in an unforgettable tale of love and hope.IntroductionUnion Carbide Corporation (UCC) was asked to build a plant for the...
In order to explain the formulae and structures of the complex compounds, or complexes, formed by transition metal salts with molecular species such as ammonia, Werner coined the terms primary valence and secondary valence, as explained in Chapter 1. These concepts remain valid today except that the term oxidation state has replaced 'primary valence' and the term coordination number has replaced 'secondary valence'. Werner had recognized that a transition metal salt could form a complex...
Green organization in Dhahran aim to save environmental energy as possible as they can. Green organization found in Dhahran 2007 , from that time , organization prepare to start this huge project in 2010 to conserve energy in Saudi Arabia . In our project team we separated our team with respect to our majors. So, we end up with five parts to work on energy conservation. The main problem in our environment that we concern on , is environment pollution and conventional energy wastes. In Saudi...
Water scarcity is a problem that has long plagued the Middle East, but no where is the crisis more severe than in the Occupied Palestinian Territories, the West Bank and Gaza Strip. Middle-Eastern water issues ha been central to my life since a young teen, when my family moved to Syria for my father's job with the German Technical Corporation (GTZ). He was the Financial Expert for the Modernisation Programme for the Syrian Water Sector, whose objective was to improve water supply and sanitation...
This section outlines the background and current conditions of the IBM Longmont campus IWRF. Background of the main toxin to be degraded, NMP, is included, as well as the current regulations and permit requirements pertinent to this project. The qualifications of the engineers chosen to work on this project are outlined.2.1 IBMInitially founded as the Computer-Tabulating-Recording-Company in 1911 after a merger of three 19th-century companies, IBM has made several major developments in computer...
The primary purpose of agriculture is to meet the demand for agricultural products, chiefly food, and raw materials for fiber manufacture. Before the rise of agriculture, the hunter-gatherer lifestyle sustain only about 4 million people globally1 but with invent of modern agriculture it now feeds 6,000 million people. Moreover , Global cereal production has almost doubled in the past 40 years mainly from the increased yields resulting from greater inputs of fertilizer, water and pesticides, new...
