This article (part 3) discusses possible health effects of exposure to plastic or vinyl odors and outgassing in building interiors and gives references to more scholarly information sources. To improve clarity and provide public information we include here information from several US government sources including the US EPA and the US ATSDR, Department of health and Human Services, Agency for Toxic substances and Disease Registry. Our page top photo shows our client pointing to a window where occupants suspected an unpleasant "plastic" odor was originating. But notice that this is an older wooden sash. Also notice those vinyl plastic curtains on either side of the window?

Plastic odors and the detection & source-diagnosis of many common odor sources observed some installations of vinyl exterior building siding or in other plastic or vinyl building products such as windows and trim are discussed at VINYL Siding or PLASTIC Window ODORS in Buildings.

For a more broad approach to diagnosing building odor sources, see ODORS, Smells, Gases in Buildings-Diagnosis & Cure and see our ODOR DIAGNOSIS CHECKLIST

Health Effects of Exposure to General "Plastic" Odors or "Vinyl" Odors in the Home

A single small exposure [to vinyl chloride] from which a person recovers quickly is unlikely to cause delayed or long-term effects. Exposure to vinyl chloride over many years can affect the liver, nervous system, and skin. Long-term exposure can cause a rare form of liver cancer.

There is no antidote for vinyl chloride, but its effects can be treated and most exposed persons recover completely. Persons who have inhaled large amounts of vinyl chloride might need to be hospitalized.-- ATSDR

  • The primary target of vinyl chloride acute exposure is the CNS. Signs and symptoms include dizziness, ataxia, inebriation, fatigue, numbness and tingling of the extremities, visual disturbances, coma, and death.
  • Vinyl chloride can irritate the eyes, mucous membranes, and respiratory tract. Escaping compressed gas or liquid can cause frostbite or irritation of the skin and eyes.
  • Chronic exposure can cause permanent liver injury and liver cancer, neurologic or behavioral symptoms, and changes to the skin and bones of the hand.
  • Vinyl chloride's acute CNS effects are likely to be caused by interaction of the parent compound with neural membranes. Other effects appear to be caused by interaction of reactive intermediates with macromolecules.-- ATSDR

Acute Exposure Exposure to Vinyl Chloride

Vinyl chloride is thought to depress the CNS via a solvent effect on lipids and protein components of neural membranes that interrupts signal transmission. Reactive metabolic intermediates may also cause specific target organ toxicity by covalently bonding to tissue or initiating destructive chain reactions such as lipid peroxidation. There may be a latent period of hours to days between exposure and symptom onset. Vinyl chloride is rapidly metabolized and the metabolites are eliminated in the urine.

Children do not always respond to chemicals in the same way that adults do. Different protocols for managing their care may be needed.-- ATSDR

Chronic Exposure to Vinyl Chloride

Prolonged absorption of vinyl chloride can induce hepatotoxicity and hepatic cancers, including angiosarcoma. Portal hypertension and cirrhosis can occur.

Vinyl chloride toxicity is thought to result from the binding of reactive epoxide metabolites to hepatic DNA. Other effects of chronic exposure include sensory-motor polyneuropathy; pyramidal, extrapyramidal, and cerebellar abnormalities; neuropsychiatric symptoms such as sleep disorders, loss of libido, headaches, and irritability; EEG alterations; and immunopathologic phenomena such as purpura and thrombocytopenia. Vinyl chloride disease is a syndrome consisting of Raynaud's phenomenon, acroosteolysis (dissolution of the bones of the terminal phalanges and sacroiliac joints), and scleroderma-like skin changes.-- ATSDR

Vinyl Chloride Exposure - Additional Opinions

The following opinion is not part of the original US EPA Article on vinyl chloride odors, exposure, and hazards shown above.

The jury may be out on the question of health effects of residential exposure to various smells and odors such as the "plastic smell" we discuss at VINYL Siding or PLASTIC Window ODORS in Buildings. Plastics are used in an enormous range of building materials and consumer products, and plastics vary widely in their properties, chemical composition, tendency to give off gases, smells, odors, and in possible health concern.

One of the plastics that has received a lot of study are those using vinyl chloride. This product might be present in some common building products such as vinyl siding and vinyl windows or screens. The US EPA has classified vinyl chloride as a Group A, human carcinogen. Vinyl chloride might be present in gas form as a colorless, flammable gas with a faintly sweet odor at levels of about 3000 ppm (the odor detection threshold). Vinyl chloride hazards are discussed above at VINYL CHLORIDE HEALTH INFO.

Because people's sensitivity to smells and odors varies widely, as does their individual health, genetics, and vulnerability, we do not offer an opinion about the actual level of risk associated with odors that individuals perceive in a building.

When readers discuss exposure to various sources of odors, some of which might be unsafe, we

  1. Put basic safety first: assure that where life and safety concerns are present, an building owner or occupant should be sure not to let worry about a less-likely hazard, even one that deserves remediation, distract attention from other more immediate, serious, and high probability hazards (fire, electrical shock, falling, smoking, failure to wear a seat belt when in a vehicle, dangerous behaviors).

    "It is the EPA's position that for a carcinogen, it should be assumed, in the absence of strong evidence to the contrary, that there is no ambient concentration that poses absolutely no public health risk." p. 76 of Standard Support and Environmental Impact Statement: Emission Standard for Vinyl Chloride (17MB large slow-loading PDF)
  2. Do not react inappropriately out of panic. Be careful about and to whom we express concerns: some contractors and consultants are understandably likely to give advice which is safest (for them) and sometimes profitable (for them) at the cost to the consumer.
  3. Obtain accurate health and exposure information wherever possible, relying on peer-reviewed, academic, and professional sources that minimize or have no conflicts of interest in the information they provide.
  4. Consult with your doctor about exposure to vinyl chloride or other gases, chemicals, or contaminants. ATSDR has provided this excellent Vinyl Chloride Exposure Questionnaire that you can complete and take to your physician.

With many substances, people are able to detect by smell a substance at very low actual concentrations. It is possible that people detect smells or odors at levels well below currently-established levels of hazard, even if risk levels have been established for the particular chemical or chemical group.

Where chemical or plastic smells are observed in a building, many readers and some experts take an approach of prudent avoidance that includes identifying and correcting the odor source and improving indoor air quality with introduction of outdoor fresh air when that is practical.

Where serious illness or major expenses are involved with exposure to a particular indoor gas or odor, expert inspection and tests can be performed by various building experts including environmental inspectors and industrial hygienists. We advise against simple "air tests" alone as without a diagnostic inspection, even if a troublesome level of exposure is detected the building owners or occupants may be left without an actual plan of action.

Dan Gold, Dan@bluevinyl.org, Co-Producer Julie Parker, Julie@bluevinyl.org - from the film's website:
    A Toxic Comedy Look at Vinyl, The World's Second Largest Selling Plastic. With humor, hope and a piece of vinyl siding firmly in hand, Peabody Award-winning filmmaker Judith Helfand and co-director Daniel B. Gold travel from Helfand’s hometown to America’s vinyl manufacturing capital and beyond in search of answers about the nature of polyvinyl chloride (PVC). Her parents’ decision to “re-side” their house with this seemingly benign cure-all for many suburban homes turns into a toxic odyssey with twists and turns that most ordinary homeowners wouldnever dare to take. The result is a humorous but sobering and uniquely personal exploration of the relationship between consumers and industry in the feature-length documentary BLUE VINYL, which won the cinematography award in the documentary competition at the 2002 Sundance Film Festival
    BLUE VINYL also poses a refreshingly simple question: “Is it possible to make products that never hurt anyone at any point of their life cycle—when manufactured, when used, or when disposed of?"
