Chemical contamination refers to the presence of unwanted substances that make the food, air, or water unfit to use. There are two forms of chemical contaminants organic and inorganic. We have chemical contaminant in the substance that we are using every day. There is property or characteristic for some contaminants which is volatile, this lead to having like these contaminates in our environment. Examples of these substances include: benzene, pesticides, deodorants, and disinfectants.
Chemical carcinogen are odorless, colorless, naturally or man-made substances responsible to cause harmful effects on the environment and the human. For example, these substances are considered …show more content…
PAHs also are present in products made from fossil fuels, such as coal-tar pitch, creosote, and asphalt (IDPH, 2009). The most common way that PAHs enter the body is through breathing air that contaminated with the PAHs such as tobacco smoke, fumes from vehicle exhaust, wildfires,coal, asphalt,coal tar, agricultural burning and hazardous waste sites. Eat or drink food and water contaminated with PAHs. Also, exposure occurs if an individual skin contacts PAH-contaminated soil or products like heavy oils, coal tar, roofing tar, or creosote. A study showed that PAHs compounds have caused tumors in laboratory animals that eat food contaminated with PAHs,breathing aircontaminated with PAHs, and when it was applied to their skin. A reproductive problems have been experienced in pregnant mice when they ate high doses of a PAH. In addition, birth defects and a decrease in their body weight appeared in the offspring of the pregnant mice. Damage to the skin, body fluids, and the immune system also have been noted, however, these effects have not been seen in
