Environmental Toxicology: Keeping Illnesses at Bay

Polluted water resources pose health risks to people, especially when ingested. The water becomes polluted because of pathogens, and pathogens are comprised of bacteria and other viruses or parasites ― some of which may be naturally occurring while there are those that come from animal or human waste. The person who happens to ingest polluted water is likely to suffer from diseases like typhoid, cholera, dysentery, polio, and hepatitis.

In rural areas, people get their drinking water from freshwater resources that might have been contaminated with waste materials. In addition, there had already been several instances of people living in urban areas who complain about water contamination from chemical wastes of nearby industrial plants. To confirm their speculations about contamination, they may seek the help of an environmental toxicologist. These professionals will assess the water samples taken and analyze their impact on human health. Toxicologists study the samples in a laboratory and this usually involves several experiments and trials.

After studying the short and long-term toxic effects of the contaminated water, they can give ways or solutions to deal with the existing damages, and keep things from getting worse. They need to come up with reports on their findings so their associates can evaluate it, and eventually arrive at an educated conclusion. These experts also make use of related literature to effectively develop preventive programs and action plans.
