Research article by Kavitha and Sugirtha (2013), on a topic evaluation and sediment quality assessment of two perennial ponds revealed that the water from selected perennial ponds are fit for domestic purposes and aquatic life. The present study was conducted to determine the sediment quality of core sediment of ponds. In this study, the concentration of all parameters were analyzed. The percentage of sand, silt and clay were observed and they found that it differed in relation to depth. Mostly, sediments in an aquatic life have a high contamination capacity especially for trace and heavy metals. In this study, five variables were considered which are cadmium, chromium, copper, lead and zinc. Several of the elements are highly hazardous…show more content…
In this research study, the aim was to determine the sediment oxygen demand (SOD) at different locations among the river and the relationship between SOD and the characteristics of the sediment. Recent analyses of contaminants associated with municipal waste waters show that sewage effluents affect both water and sediment quality. Neary (2008) reported that nutrients and waste discharge with high concentrations of organic compounds can lead to anaerobic conditions as a result of the decreased DO concentrations. In a recent studies by Pratheesh and Sujatha determined whether the water from the selected sites are fit for the aquatic life and used freshwater to meet domestic purposes. They reported that the problems related to shortage, misuse and pollution of water are becoming more and more complex with increasing population, industrialization, commercialism and urbanization.
In the hydrological cycle, less than 0.1% of the metals were actually dissolved in the water and more 99.9% were stored in sediments and soils (Karbassi et al., 2007 and Pradit et al., 2010). They discovered that their toxicity can bring into heavy metal pollution and it was one of the largest threats to their environment that affects directly on flora, fauna and health. They conclude in this research that various sources of heavy metals were some originates from anthropogenic activities like draining of sewage, dumping of
