Federal action is needed to rapidly reduce exposure to toxic chemicals, such as vinyl chloride*, used in the production of polyvinyl chloride (PVC) that appears in everything from wall and floor coverings to children’s toys to cars. It also has excellent stretch properties at high temperature, making it ideal as a material for secondary processing such as vacuum molding. These exposures have resulted in what has been called “vinyl chloride disease,” a syndrome consisting of Raynaud’s phenomenon (blanching, numbness, and discomfort of the fingers upon exposure to cold), degeneration of the fingertip bones (acroosteolysis), joint and muscle pain, and stiffness of the hands with skin changes. Equally disturbing is the fact that PVC manufacturing plants are disproportionately located in low-income neighborhoods and communities of color, making exposure to this toxic chemical not only an issue of health and the environment, but also an issue of environmental justice.

Vinyl chloride monomer (VCM) is a colorless, flammable, important chemical intermediate used almost exclusively to produce polyvinyl chloride (PVC) resins; therefore, VCM follows the PVC market trend very closely. Vinyl does not corrode like some building materials, does not require frequent painting and can be cleaned with mild cleaning products. Acute (short-term) exposure to high levels of vinyl chloride in air has resulted in central nervous system (CNS) effects, such as dizziness, drowsiness, and headaches in humans. Acidity in vinyl chloride can be quantified by measurement of hydrogen chloride (HCl) levels, serving as a quality measure and preventing corrosion of the storage and handling equipment. Vinyl chloride has been found in the air near vinyl chloride manufacturing and processing plants, hazardous waste sites, and landfills.
