Cost-effective estimation of bioaccumulation potential
There are various methods of determining the bioaccumulation potential including, laboratory test, field monitoring and use of models. Among the three methods, the most easily and least expensive is the laboratory test. This method is simple in such a way that the organisms are placed in vessels that contain sediments and superimposing water, and then they are allowed to accrue contaminants from the sediments for a specific period of time. Chemical analysis is usually done on the sediments to establish a chemical data that will be used to compare the toxicity of the result with any other result.
It can be said that the method is effective as control of the environmental condition is made possible. Laboratory methods provide more sense of flexibility in terms of timing and it reduces workload and cost as well as seasonal and spatial variability (U.S. EPA 2000a). The use of laboratory test can enable one to formulate research question such as kinetics of acceptance and eradication, growth of the species or reproduction. This tech...
Devastating poisoning of metals arise from drinking-water pollution (e.g. lead channels), high surrounding air fixations close to emission sources, or through food chain. Heavy metals are unsafe on the grounds that they have a tendency of bioaccumulation. Bioaccumulation implies an increment in the convergence of a substance in a biotic organism overtime contrasted with chemical concentrations in the environment. Mixes gather in living things at whatever time they are consumed and saved speedier than
Introduction Mangroves are plants that live along the coastline, between fresh and seawater, and often around estuaries. They are among the most complex and productive ecosystems in the world, and have amazing evolutionary adaptations which allow them to not only survive but thrive in an environment where no other species could. They provide a habitat for countless animals, all contributing to the ecosystem. The topics that will be discussed are the environmental, economical and social values of
"The children who have no clean water to drink, the women who fear for their safety, the young people who have no chance to receive a decent education have a right to better, and we have a responsibility to do better. All people have the right to safe drinking water, sanitation, shelter and basic services." Ban Ki-moon, UN Secretary General (Ki-moon, 2014) Abstract Nile River has come under increasing pressure recent years as the population grows. It depend on the water for irrigation, drinking
