Both anthropogenic activities and natural processes cause its release into different spheres of the environment resulting in severe adverse impacts (Pacyna et al, 2015). Generally, mercury sticks to bacteria and phytoplankton in the water. Introduction. Running head: MERCURY IN OUR COMMUNITY 1 Introduction This case will be focused on pollution caused on a local lake by mercury contamination. Mercury pollution results in neurological and behavioural disorders in humans. Mercury (Hg) is a naturally occurring unique silvery metallic element with special property of being liquid at room temperature (Tangahu et al, 2011, Norrby, 2011). The Concept of Pollution Any change in the physical, chemical, or biological characteristics of the air, water, or soil that can affect the health, survival or activities of humans or other forms of life in an undesirable way. Larger fish eat the smaller ones, and they also suffer. But mercury pollution is likely to be causing serious harms other than decrements of population averages of IQ. Mercury pollution is the pollution caused by the release of mercury from the mercury products or emissions from coal-burning power plants in air, water or land. Almost all mercury compounds are toxic and can be dangerous at very low levels in both aquatic and terrestrial ecosystems. Rank the following items from the lowest amount of water needed to produce 1kg of that item at the top to the most water at the bottom. We synthesize understanding of sources, atmosphere-land-ocean Hg dynamics and health effects, and consider the implications of Hg-control policies. Mercury Pollution A review will show that the existing laws and regulations related to mercury pollution in small-scale gold mining are fairly adequate but monitoring and enforcement is weak. A good example of the bioaccumulation process is mercury contamination. Soil pollution:-Soil pollution is when people introduce harmful objects, chemicals, or directly or indirectly in the territory of in such a way as to avoid injury to other living things or damage the soil or water ecosystems. avoid producing pollutants in the first place. Because mercury is a persistent substance, it can build up, or bioaccumulate, in living organisms, inflicting increasing levels of harm on higher order species such as predatory fish and fish eating birds and mammals through a process know as "biomagnification". Individual Steps for Pollution Prevention. ... out the general concept of mercury pollution . It will explain in details to the community involved about the risks involved with swimming and fishing from the lake as a result of the mercury pollution. The cheapest and most effective way to reduce pollution is to avoid producing pollutants in the first place. The "falling action" is a part of the story that usually happens right after the climax.It is the transition from climax (peak) to denouement (ending) of the story. Insomnia, memory loss, headaches, tremors are some of the symptoms of mercury pollution. Small fish which feed on that bacteria can accumulate mercury in their bodies. The concept of pollution prevention centers around the idea of eliminating the creation of pollutants. Mercury (Hg) is a global pollutant that affects human and ecosystem health.
