[Risks to consumers and PVC workers from vinyl chloride]
Schweizerische Medizinische Wochenschrift
|May 1, 1976
Summary
Worker exposure to vinyl chloride in PVC factories has decreased, significantly reducing the risk of vinyl chloride disease and liver hemangiosarcomas. Consumer exposure from PVC packaging is negligible, posing no health risk.
Area of Science:
- Occupational Health
- Toxicology
- Polymer Chemistry
Context:
- Vinyl chloride (VC) is a monomer used in Polyvinyl Chloride (PVC) production.
- Historically, occupational exposure to VC has been linked to serious health issues, including angiosarcoma of the liver.
- Recent advancements in industrial hygiene have focused on reducing worker exposure levels.
Purpose:
- To assess the current health risks associated with occupational exposure to vinyl chloride in PVC polymerization factories.
- To evaluate the safety of consumer exposure to residual vinyl chloride in PVC packaging.
Summary:
- Worker exposure to vinyl chloride in PVC polymerization factories has been substantially reduced over the past two years.
- Current occupational exposure levels are expected to eliminate new cases of vinyl chloride disease and reduce liver hemangiosarcoma risk to general population levels.
- Consumer exposure to vinyl chloride from PVC food packaging is significantly below carcinogenic thresholds, indicating no associated health risk.
Impact:
- Improved worker safety and reduced incidence of occupationally-related cancers in the PVC industry.
- Reassurance for consumers regarding the safety of food packaged in PVC materials.
- Establishes a benchmark for safe working conditions in chemical manufacturing environments.

01:18Carboxylic Acids to Acid Chlorides
Carboxylic acids react with SOCl2 or PCl5 to form acid chlorides. Amongst the carboxylic acid derivatives, acid chlorides are the most reactive and synthetically important derivatives. They are useful reagents for Friedel–Crafts acylation of some aromatic compounds.
01:09Radical Chain-Growth Polymerization: Mechanism
The radical chain-growth polymerization mechanism consists of three steps: initiation, propagation, and termination of polymerization. The polymerization initiates when a free radical generated from the radical initiator adds to the unsaturated bond in the monomer. The unpaired electron of the free radical and one π electron in the unsaturated bond creates a σ bond between the free radical and the monomer. As a result, the other π electron in the unsaturated bond converts this species into the...
01:27Effects of Chemicals: Overview
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...
01:36Types of Toxins
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

01:26Toxic Reactions: Overview
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

01:31Plasticizers
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...
