The Effects Of Water Pollution

905 Words4 Pages
Pollution is a term applied to any environmental state or manifestation which is harmful or unpleasant to life, resulting from failure to achieve or maintain control over the chemical, physical or biological consequences or side effects of human scientific, industrial and social habits (Feugo, 2008; Anderson et al., 2005). From another perspective, water pollution refers to any physical, biological or chemical change in water quality that adversely affects living organisms and makes water unsuitable for desired uses as a result of anthropogenic activities (Cunningham and Saigo, 2003; Anderson et al., 2005). Many human activities from water supply and sanitation to transport, mining and the chemical industry have the potential to pollute…show more content…
Other tests are not rapid, making consumers of water susceptible to waterborne diseases. In this study, dye-doped, surface functionalized silica nanoparticles (SiNP) and surface- functionalized magnetic nanocomposites (MNCs) were proposed as materials that can be applied in order to reduce the time taken to get results as well as to make the processes less complex and portable. The aim of this study was to synthesize and characterize surface functionalized dye-doped SiNPs and surface functionalized MNCs for detection and pre-concentration of in water (Mahlangu, 2016), Yi et al., (2011) and Gasteiger et al., (2005) also revealed the use of (SiNP) and (MNCs) in detection and pre-concentration. Faecal coli form and E. coli contaminations in effluent- dominated streams The study assessed the water quality of the upper Santa Cruz watershed in southern Arizona in terms of faecal coli form and Escherichia coli bacteria concentrations discharged as treated effluent and from nonpoint sources into the Santa Cruz River and surrounding tributaries. The objectives were to (1) assess the quality in the upper Santa Cruz Watershed in terms of faecal coli form and E. coli by campaign available data to the water quality criteria established by Arizona, (2) to provide insights into faecal indicator bacteria (FBI) response to the hydrology of the watershed and (3) to identify if point sources or nonpoint sources are the major contributors of
