The Effects Of Water Pollution On The Environment And Human Health
Every day, 14,000 people die as a result of drinking polluted water (Agrawal, Pandey, Sharma, 2010). Agrawal et al, (2010), claims that water pollution occurs when there is an addition of contaminants to the extent that the water either cannot serve to humans for drinking purposes and or to support the life (p.432). Water pollution is a global problem which has been caused by the Industrial Revolution and technological development (Agrawal et al-2010). Human activities have had a major impact on the water quality (Ebenstein 2012). Water pollution can have dangerous long-term effects on the environment and human health. Water pollution can have dangerous long-term effects on the environment and human health.
There are several causes of water pollution. Agriculture runoff is responsible for over 50% of water pollution found in streams and rivers (Agrawal et al., 2010). According to Agrawal et al. (2010), pesticides and herbicides used on plants end up in rivers, lakes, and oceans by surface run-off. These pesticides may be absorbed by the organisms in the water (Agrawal et al., 2010). Agrawal et al. (2010) also state that in Canada and the USA, 39 different pesticides have been found in the ground water. Agricultural runoff can create a bad taste and odor in drinking water and contaminated drinking water, well water, and food sources. The pesticides in runoff can accumulate in fish, which can expose people who eat the fish to high levels of these…
