Plastic and Environment A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. Composition Most plastics contain organic polymers. The vast majority of these polymers are based on chains of carbon atoms alone or with oxygen‚ sulfur‚ or nitrogen

An oil spill can be defined as an accidental or deliberate dumping of oil or petroleum products into the ocean and its coastal waters‚ bays‚ and harbors‚ or onto land‚ or into rivers or lakes (Holum 1977). Between one and ten million metric tons (one metric ton is 1000 kilograms) of oil are put into the oceans every year. The oil is released‚ most often‚ in small yet consistent doses from tankers‚ industry‚ or on shore waste disposal (Boesh‚ Hersher‚ et al. 1974). Tanker spills cost the United

was not something that people paid attention too. As the science involved‚ people began to realize the problem with pollution. Many different sources cause air pollution. Automobiles that are burning gasoline produce very harmful gases and incineration of products. Factories produce millions of particles that are carried off into the air. Gaseous by-products produced by chemical plants release these toxic gases when their concentration is at a high enough level. As the world has become more

Introduction: Vanadium is a hard‚ silvery grey metal. Vanadium was discovered by Andrés Manuel del Río‚ a Spanish-born Mexican mineralogist‚ in 1801 [1]. Some sources say Vanadium is soft because it is ductile [1]. Vanadium is harder than most metals and steels [1] It is resistant to corrosion and it is stable against alkalis‚ sulfuric and hydrochloric acids[1]. It is oxidized in air at about 933 K (660 °C‚ 1220 °F) [1]. This paper will discuss the effects of Vanadium on the environment and Vanadium’s

SOIL POLLUTION INTRODUCTION Soil is the thin layer of organic and inorganic materials that covers the Earth’s rocky surface. The organic portion‚ which is derived from the decayed remains of plants and animals‚ is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments‚ was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient

first solution to reduce air pollution is by using vehicles wisely. The use of vehicles can produce gases causing air pollution such as carbon monoxide (CO). “It is largely made up of pollutants emitted from fuel-burning vehicles‚ factories‚ waste incineration‚ smoking‚ and more.” (Simmons‚ 2013). To reduce the use of private vehicles‚ we can start to use public transports such as city buses. The use of public transports will reduce the burning of fossil fuels. Another alternative is by riding a bicycle
