Answer:
Explanation:
For decades, commercial dry cleaners have relied on a chemical solvent known as perchloroethylene or "perc" to get clothes clean. But, like many "miracle" cleaners that were supposed to make our lives easier, perc has been found to cause significant environmental and human health problems.
Perc is a chlorinated hydrocarbon chemical that creates dioxin vinyl chloride, carbon tetrachloride and phosgene during its manufacture and breakdown processes. It is a volatile organic compound (VOC) and permeates the air in most dry cleaning establishments (the sweet chemical smell we're all familiar with). Perc is a common groundwater contaminant, and is extremely difficult to remediate once it has entered an ecosystem.
Primary exposure to perc is through inhalation and ingestion from contaminated water sources. Human health problems associated with exposure to perc include nervous system damage, liver and kidney damage, several types of cancer and reproductive impacts (perc passes easily from the mother to the fetus).
