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

the movement of water. The stems consisted of many aerenchyma cells. Aerenchyma cells can be found in the roots and stems. Aerenchyma cells involved in the process of storing gases which is needed for respiration and give many air spaces to provide buoyancy so that the plant can float on the surface of water. Aerenchyma cells also allow diffusion of water from upper positions of the plant into the roots. Thus‚ the roots can easily obtained oxygen without depending to the soil. Apart from that‚ the submerged

wind turbine platforms. For deepwater wind turbines‚ a floating structure may replace driven monopoles or conventional concrete gravity bases that are commonly used as foundations for shallow water turbines. A floating structure must provide enough buoyancy to support the weight of the turbine and to restrain pitch‚ roll and heave motions within acceptable limits. The turbine design philosophy for floating may be impacted if platform dynamics require a more dynamically compliant machine but the platform

Identity of Cyanobacterial Toxins Cyanobacterial toxins are toxins produced by cyanobacteria‚ or blue-green algae. They include neurotoxins (e.g.‚ anatoxins)‚ hepatotoxins (e.g.‚ microcystins)‚ skin irritants and other toxins. Both hepatotoxins and neurotoxins are produced by cyanobacteria commonly found in surface water supplies and therefore appear to be of most relevance to water supplies at present.1-3 However‚ the neurotoxins are relatively unstable and‚ as such‚ are not considered to be as
