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

Everything you need to know about hydrocarbons INTRODUCTION: organic chemistry Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different

Synthesis of Phenols You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid‚ by the Dow process‚ and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. Pyrolysis of sodium benzene sulfonate In this process‚ benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt

CHAPTER I INTRODUCTION Background of the Study Mangrove swamps are forested intertidal ecosystems that occupy sediment-rich sheltered tropical coastal environments. By trapping and stabilizing fine sediments‚ mangroves control the quality of marine coastal waters. Aside from maintaining coastal food webs and populations of animals‚ mangroves have an important role in pollution control through their absorptive capacity for organic pollutants and nutrients‚ and they play an important role in storm

Chapter I The Problem – Its Background Our environment today is experiencing a lot of superfluous phenomena like floods‚ earthquakes and other incidents and pollution is the root of all of these incidents. Serving the environment would be a big help to Mother Earth. The researchers decided to make junk into a new and useful thing that may be used by students and that may be a progress in our economy. Plastic is one of our society’s main problems for it is hard to decompose; it takes years to
