Vinyl Chloride in Drinking-water from World Health Organization.

"soluble in almost all organic solvents. It is heavier than air & can spread over the ground, creating an exposure long distances away from the original source.

"In the atmosphere, vinyl chloride exists almost entirely in the vapour phase & reacts with hydroxyl radicals and ozone, ultimately forming formaldehyde, carbon monoxide, hydrochloric acid & formic acid; its half-life is 1–4 days."

"When released to the ground, vinyl chloride is not adsorbed onto soil but migrates readily to groundwater, where it may be degraded to carbon dioxide and chloride ion or remain unchanged for several months or even years".

"Exposure of the general population may be higher in situations where large amounts of vinyl chloride are accidentally released to the environment, such as a spill during transportation. However, such exposure is likely to be transient".

"Unplasticized PVC (uPVC) is increasingly being used in some countries for water mains supplies. Migration of vinyl chloride monomer from uPVC is a possible source of vinyl chloride in drinking-water".

"Studies into PVC-bottled drinking-water have identified vinyl chloride at levels of .06–.18 µg/litre & <0.6 µg/litre...frequency of occurrence of vinyl chloride is expected to be higher in such water than in tap water".

"Because vinyl chloride is volatile, exposure by
inhalation while showering with contaminated water could be expected".
