Wetland Pollution Essay

1576 Words7 Pages

Wetland pollution is responsible for dangerous hazards that affect developing and developed countries. Industrialization and production of chemical compounds led to worldwide deterioration of the environmental quality (Chakravarty et al. 2010). The contamination of the aquatic ecosystems with metals is a worldwide and local problem. Trace metals are toxic when present in excess concentrations. These metals can accumulate along the food chain, because of their solubility and mobility (Yan et al. 2010). This eventually leads to serious health and ecological hazards.
Wetlands are natural filters for the reduction of pollutants transported by water in water bodies and thus they are considered as effective, low-cost, cleanup option to improve the quality of surface waters. It was reported by many investigators that the vegetation covering the wetland areas and the associated microorganisms plays an important role in sequestering large quantities of nutrients and metals (e.g. Cronk and Fennessy 2001; Eid et al. 2012; Galal and Shehata 2014). Analyzing water, sediments, macrophytes and animals can determine trace metal contamination of the aquatic ecosystem (Dummee et al. 2012). Metal concentrations in sediments are generally much …show more content…

These impacts result from agricultural, human and industrial activities, which contaminate the water body of the lake. Trace metals are the main contaminants of the discharged waste effluents in the lake. These metals and much of the industrial wastes cannot be degraded and therefore, accumulate in water, sediments, and living organisms in the lake. Therefore, the main objective of this study was to assess onsite phytoremediation potential of the aquatic plant R. sceleratus for the cleanup of polluted lake water with trace metals. Moreover, the impact of these trace metals on the growth performance of the plant was

An excess level of selenium, which is taken into the body in water and foods, can cause significant side effects like nausea, vomiting, nail changes, irritability in the nose and throat (producing coughing, nosebleeds, dyspnea, bronchial spasms and chemical pneumonia). Exposure to lower levels of Arsenic in the short term can cause nausea and vomiting, swelling and redness of the skin, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels and a sensation of “pins and needles” in hands and feet.

The sulfur in the agricultural fertilizers leads to accumulation of toxic mercury in fish, birds, and mammals. Also, exotic animals or invasive species displaced native and threatens to disrupt the ecosystem balance. The purpose of this experiment is to determine how the water quality affects the Everglades ecosystem and how water pollution impacts different species. Urbanization is a big threat that contributes to poor water quality in water pollution.
