There have been many studies performed that are providing us insights to pollution issues surrounding us. Lately, some of them have been focused on the quality of surface run-off and contaminants therein.
Unfortunately many people still believe that the water rolling around on the ground from rainfall is clean and contaminant free. Research has shown that run-off is loaded with contaminants that are potentially harmful to wildlife and humans.
Researchers use the brown Bullhead catfish as an indicator of environmental pollution impacts, according to an ENN news brief (Environmental News Network). Many of the toxins deposited in our waters are stored in the bottom soil layer. The Bullhead catfish feeds along the bottom, therefore would be prime studies for long-term effects of pollutants. Studies are completed specifically on the Bullhead catfish populations residing in the Anacostia River, Washington D.C.. Sadly, the incident rate of liver tumors on this population is significantly higher than that of other areas. This issue should be taken very seriously, as carcinogens affect humans as well. When humans impact the environment either directly or indirectly, it is known as anthropogenic impact. Pollution is an exemplary "anthropogenic impact". There is a very complex relationship between society and the environment, which is not always positive. I once read a quote that very effectively captures how we should view the environment... "When we see land as a community to which we belong, we may begin to use it with love and respect." - Aldo Leopold Originally written for writtenbyme.com Go To Page: 1
