PVC Fact Sheet
PVC products are to the
chemical industry what cigarettes are to the
tobacco industry: the lynchpin of a toxic economy.(1)
PVC, polyvinyl
chloride, is a chlorinated plastic. PVC is made
from two carcinogens, ethylene dichloride and
vinyl chloride monomer. Production of PVC
generates dioxin, a known human carcinogen.
Independent studies show that PVC production is
among the largest sources of dioxin emissions to
the air, land, and water. Also, PVC contains
toxic additives such as cadmium, lead,
phthalates, and organotins.
Phthalates and organotins are
endocrine disrupters. Endocrine disrupters are
man-made chemicals which act like hormones, such
as estrogen. Endocrine disrupters interfere with
normal functions of the hormone systems in
humans. Hormones are potent biological substances
which act as chemical messengers. Even small
amounts can produce large effects. Hormones
regulate critical body functions including
behavior, development, and reproduction. The
endocrine system controls growth, organ
development, metabolism, kidneys, body
temperature, and other essential functions.
Most endocrine disrupters are
fat soluble compounds which tend to remain in the
environment, in animals, and people for very long
periods. Endocrine disrupters are
persistent they are not metabolized by
bacteria and they do not degrade well in the
environment, and they bioaccumulate they
are concentrated in the food chain when humans
and animals eat plants and animals containing
them.
Polyvinyl chloride (PVC)
plastics entire life cycle, from production
through use and disposal, has negative
environmental impacts. PVC is made from two
carcinogens, ethylene dichloride (EDC) and vinyl
chloride monomer (VCM). The production of PVC
creates large amounts of toxic chemicals,
including dioxins, furans, PCBs, and
hexachlorobenzene. (2)
The PVC industry has been
plagued by worker health and safety issues for
decades. The industry was aware of health
problems among PVC plant workers, including high
rates of cancer, for decades before that
information was shared with regulators or
workers. The industry spent years using public
relations and manipulating science in order to
avoid disclosure and liability for worker illness
and deaths. A Federal Court has noted that,
The record shows what can only be described
as a course of continued procrastination on the
part of industry to protect the lives of its
employees. (2)
PVC is widely used to
make building materials, pipes, furniture, and
automobile components. When PVC is burned in a
fire it gives off toxic hydrogen chloride gas
which turns into hydrochloric acid on contact
with moisture in the lungs. PVC is involved in a
large portion of the approximately one million
building and automotive fires in the U.S. each
year. Combustion of PVC in accidental fires may
be a significant source of dioxin in the
environment. (2)
When PVC is burned in
medical waste and garbage incinerators, it is
among the largest single sources of dioxin in
those burners. Extremely toxic heavy metals in
PVC, such as lead, cadmium, and chromium, are
also released from the stacks and end up in the
ash of these incinerators. (2)
PVC ingredients and their
toxic by-products have contaminated the air,
soil, and water of communities on the Gulf Coast
of Louisiana and Texas where the industry is
concentrated. (2)
Studies in Netherlands,
Sweden, and Germany have all found elevated
levels of dioxins in wastewater discharges,
sludge, and sediments at PVC production
facilities. Greenpeace collected samples from
nine US plants that produced EDC or VCM. Four
samples were analyzed for dioxin and 25 for other
substances used in the production of these
chemicals. They found that:(2)(3)
| A sample of
heavy end waste from the
distillation of EDC contained 200,750 ppb
of dioxin at Vulcan Chemicals in Geismar,
Louisiana. A
sample of heavy end waste from the
distillation of VCM contained 761 ppb of
dioxin at Formosa Plastics in Point
Comfort, Texas.
A sample collected from
a tank containing process waste contained
1,248 ppb of dioxin at Georgia Gulf
Corporation in Plaquemine, Louisiana.
A sample collected from
sediment downstream from the discharge
point contained 2,911 ppt of dioxin at
Geon Corporation (formerly BF Goodrich)
in La Porte, Texas.

Virtually
all of the products made of PVC have safer
substitutes available, making the risks posed by
PVC completely unnecessary and unacceptable.(2)
Phase-out PVC
1. Reduce and eliminate
production and use of PVC to zero. Give priority
to uses that are incinerated or burned in
accidental fires, and those most easily replaced
with safe, non-toxic substitutes. More rapid
phase-outs should occur for PVC used in
packaging, childrens toys, medical
supplies, and construction materials.
2. Phase-out existing PVC
plants
3. Permit no new facilities
4. Phase-out and eliminate
burning PVC waste in incinerators
Ensure a Just Transition for
Workers
A tax during phase-out on the
production of EDC and VCM would help drive the
transition away from PVC and would finance the
costs associated with it. The revenues would be
used to ensure a just, equitable, and orderly
transition for workers. For example, funds could
be used for new job training, income protection,
health insurance, and research and development of
non-PVC alternatives.(1)

Highlights
From the Greenpeace Report
http://www.greenpeaceusa.org/toxics/vinylhouse/highlights.htm
Greenpeace Findings
All products tested contained detectable levels
of phthalates (THA-LATES), with a maximum of 39%
by weight in a drinking straw. Some of the
highest levels were found in products
specifically designed for children's mouths.
Nearly all of the products contained significant
amounts of organotins. Wallpaper and floor tiles,
on which children spend a lot of time crawling
and playing, were the two products containing the
highest levels.
Two products contained Bisphenol A, a chemical
that affects the hormone system.
Vinyl products for everyday use, containing
larger amounts of hazardous additives than any
other plastic, can be readily purchased at
popular retail stores in the United States.
PVC and Additive Use
Over 76% of all vinyl in the United States is
used in building construction - this includes
flooring, wallcoverings, pipes, siding, etc.
Worldwide, 86% of all phthalates are used in PVC
and nearly 70% of all organotins are used in PVC.
PVC additives are not chemically bound to PVC,
but can be released like moisture from a damp
sponge.
It has been known for 30 years that additives
leach from soft PVC.
Phthalates
Humans have phthalates in our bodies. A recent
(2001) Centers for Disease Control (CDC) study
confirmed the presence of two of the phthalates
detected in the Greenpeace study in a test
population.
The offspring of rats fed the three phthalates
detected in the Greenpeace study, DEHP, DINP and
BBP, do not follow normal patterns of sexual
development.
There is reason for concern that DEHP may impair
male reproductive system development in human
infants and toddlers. The Environmental
Protection Agency (EPA) and the Department of
Health and Human Services (DHHS) consider DEHP to
be a probable human carcinogen.
DINP causes liver tumors and damages the kidneys
in rats and mice. DINP has also been shown to
cause cancer in laboratory animals.
Organotins
Breathing or swallowing organotins can interfere
with the nervous system, and even cause death at
high levels of exposure in humans.
Organotins have adverse effects on marine
wildlife and rats, including reduced reproduction
and developmental problems.
Organotins build up in the fat of fish, rats and
mice.
Right to Know
Manufacturers do not provide information on
additives in PVC plastic.
In 1999, the European Commission issued a
European-wide emergency ban that eliminated
phthalates in toys designed to be put in the
mouths of children under three.
The European Commission is currently debating
European wide restrictions on PVC use and
disposal.
In the US, the Consumer Product Safety Commission
made a voluntary agreement in 1986 with toy
manufacturers to not use DEHP (above 3%) or DINP
(1998) in teethers and rattles.
PVC-Free Business
Companies such as Mattel, Ikea, Lego, General
Motors, Honda, Nike, Norm Thompson Outfitters and
hundreds of others have committed to pursuing
alternatives to PVC for their products.
