Working environment factors
How does Acetaldehyde affect workers’ health?
Nov
Acetaldehyde, a common chemical compound found in many work environments, can have a significant impact on the health of workers. In this article, we will learn about the sources of acetaldehyde in the work environment, as well as the effects it can have on the health of those working in these conditions. From scientific studies to safety measures, we will explore important information related to acetaldehyde and how it affects worker health.
1. What is Acetaldehyde?
Acetaldehyde, also known as ethanal, is a chemical compound with the chemical formula C2H4O. It is a colorless liquid with a rather strong odor, often described as the smell of alcohol, and can irritate the eyes and throat. Acetaldehyde is commonly used in many industries, including plastics production, pharmaceuticals, and food processing.
In addition, acetaldehyde is also an intermediate product in the conversion of ethanol (ethyl alcohol) to acetic acid during fermentation, a common biological reaction in the production of wine and beer.
However, if exposed to acetaldehyde at high and prolonged levels, especially in an unsafe work environment, it can pose a risk to human health. This makes the management and control of acetaldehyde a concern in industries and labor environments.

2. Where does Acetaldehyde originate from in the production process?
Acetaldehyde can arise from many different sources during production processes and industrial activities. Here are some common sources:
- Fermentation in wine and beer production: Acetaldehyde is an intermediate product in the conversion of ethanol (ethyl alcohol) to acetic acid during fermentation. Therefore, in the wine and beer production industry, acetaldehyde can appear as a byproduct.
- Food processing: Acetaldehyde can also appear during food production and processing, especially during fermentation and cooking.
- Plastics and polymer industry: Acetaldehyde is an important compound in the production of many types of plastics and polymers. It can appear in processes such as the production of polyethylene, polyvinyl acetate, and other types of plastics.
- Chemical manufacturing: In the chemical industry, acetaldehyde is often produced as an intermediate compound to produce other chemical compounds.
- Natural sources: Acetaldehyde can also occur naturally in the environment from biological processes, such as the fermentation process of bacteria in the soil.
3. Industries that use Acetaldehyde in production
Acetaldehyde (or ethanal) is used in many different industries due to its diverse and flexible properties. Here are some common industries where acetaldehyde is used in the production process:
- Plastics and polymer production industry: Acetaldehyde is a key raw material in the production process of many types of plastics, including polyethylene, polyvinyl acetate, and other polymers.
- Chemical production industry: Acetaldehyde is used as an intermediate compound to produce many other chemical products, such as acetic acid, butanol, and other organic compounds.
- Beverage and food production industry: In food and beverage production, acetaldehyde may be used in fermentation and flavoring processes.
- Wine and beer production industry: Acetaldehyde is a byproduct in the fermentation process to produce wine and beer.
- Pharmaceutical production industry: In some cases, acetaldehyde may be used as a raw material in the production of some types of pharmaceuticals.
- Cosmetics production industry: Acetaldehyde may appear in some cosmetic and personal care products.
- Detergent production industry: Some detergent products may contain acetaldehyde as an ingredient.
4. How does Acetaldehyde affect workers
Acetaldehyde can affect the health of workers depending on the level of exposure and duration of exposure. Here are some typical effects that acetaldehyde can cause:
- Irritation of eyes and respiratory tract: Acetaldehyde has a fairly strong odor and can irritate the eyes, respiratory tract, and digestive tract. Prolonged and high-level exposure can cause feelings of pain, nausea, and discomfort.
- Effects on the nervous system: If workers are exposed to high levels of acetaldehyde, it can affect the nervous system, causing dizziness, headaches, and even nausea.
- Effects on the respiratory system: Long-term exposure to acetaldehyde via the respiratory tract can cause respiratory problems, including irritation of the lung lining and potentially bronchitis.
- Effects on the digestive system: Acetaldehyde can cause irritation to the digestive tract and if exposure is long-term, it can affect digestive organs.
- Toxic effects on the liver: Acetaldehyde is a toxic substance that can harm the liver, especially when workers are exposed to it in an unsafe work environment.
- Cancer risk: Many studies have linked acetaldehyde to the risk of developing cancer, especially oral and throat cancer. Therefore, long-term and high-level exposure can increase this risk.
To protect workers from the negative effects of acetaldehyde, occupational safety management, wearing appropriate personal protective equipment, safety training information, and controlling exposure levels are very important in work environments where this substance is used.
5. Permissible safe concentration of Acetaldehyde for human exposure
The permissible safe concentration of acetaldehyde for human exposure is regulated by occupational safety and health management organizations. Safety limits are often established to minimize risks to human health. However, these limits may vary by country and industry. Here are some common safety limits:
- The Occupational Safety and Health Administration (OSHA): OSHA has established a safety limit for acetaldehyde in the air of 25 parts per million (ppm) over an 8-hour workday (8-hour time-weighted average – TWA). Additionally, OSHA also sets a TWA limit of 15 ppm for work environments in the detergent manufacturing industry.
- The American Conference of Governmental Industrial Hygienists (ACGIH): ACGIH has established a TWA safety limit for acetaldehyde of 1 ppm.
- The National Institute for Occupational Safety and Health (NIOSH): NIOSH recommends a TWA safety limit of 1 ppm for acetaldehyde.
6. Measures to minimize the effects of Acetaldehyde on worker health
To minimize the effects of acetaldehyde on worker health, several safety and risk management measures can be applied in the work environment. Here are some measures that organizations and businesses can implement:
- Manage exposure levels:
- Identify and maintain acetaldehyde exposure levels at safe limits according to prescribed thresholds.
- Implement exposure control measures such as using effective ventilation systems and safe work procedures.
- Use Personal Protective Equipment (PPE):
- Ensure workers use appropriate PPE such as helmets, safety glasses, and respiratory masks to reduce direct contact with acetaldehyde.
- Occupational safety training:
- Provide training on occupational safety and the use of toxic substances like acetaldehyde.
- Instruct workers on how to use PPE and other safety measures.
- Control the work environment:
- Enhance ventilation and air treatment systems to reduce acetaldehyde levels in the work air.
- Install absorption or adsorption devices during the production process to reduce worker exposure.
- Health monitoring:
- Conduct periodic health checks to monitor the effects of acetaldehyde on workers.
- Build medical records to track health issues related to acetaldehyde.
- Use environmentally friendly production methods:
- Research and implement environmentally friendly production methods to reduce the amount of acetaldehyde generated.
- Comply with safety and environmental regulations:
- Adhere to all safety and environmental regulations and standards related to the use of acetaldehyde.
Periodically organize occupational environment monitoring in factories and enterprises, collect and analyze factors harmful to workers, thereby adjusting to reduce hazard levels to prevent occupational diseases for them.
