Introduction of  Health Hazards

 Acetaldehyde is a highly reactive chemical that is widely used in several industries. It is a by-product of the Ethanol. Exposure to Acetaldehyde causes health and environmental hazards.  Acetaldehyde is essential in producing perfumes, acetic acids, and resins. It is also found in fermented foods, beverages, cigarette smoke, and vehicle emissions.      

Despite its relevance in industrial and biological sectors, Acetaldehyde causes several health and environmental risks. It can cause several hazards with both short-term and long-term effects.   Let’s delve into the potential hazards of Acetaldehyde, its effects on humans and the environment, and the safety measures to lower the risks.     

Health Hazards Due to Acetaldehyde Exposure   

According to OSHA (Occupational Safety and Health Administration), the Permissible Exposure Limit (PEL) for Acetaldehyde is 200 ppm (parts per million) over an 8-hour working day. Despite several safety guidelines such as NIOSH (National Institute for Occupational Safety and Health) recommendations and EPA (Environmental Protection Agency) air quality standards, workers may still experience health issues from exposure to Acetaldehyde, resulting in short-term (respiratory problems, eyes, and skin irritation) to long-term (throat and lungs damage). Take a look at the key points of the acute health effects experienced by the workers. 

 

Acute Health Effects or Short-Term Effects 

The level of health effects differs based on the concentration and duration of exposure to Acetaldehyde.  

   

  • Respiratory Irritation   

Through inhalation of Acetaldehyde vapors from fermentation in breweries can cause throat, lung, and cough irritation at low exposure levels. Higher levels of exposure can lead to pulmonary Edema, coughing, erythema, and necrosis.  

 

  • Eye and Skin Irritation   

Exposure to Acetaldehyde exhaust fumes in automobile industries can cause mild to severe eye irritation, including redness and watering. In resin and plastic manufacturing industries, direct contact with liquid Acetaldehyde may lead to a burning sensation on the skin. 

   

  • Headaches and Dizziness   

Sometimes, in brewery industries, workers inhale high levels of Acetaldehyde from fermentation tank, which leads to affect the central nervous system (CNS), headaches, dizziness, nausea. 

 

Chronic Health Effects or Long-Term Health Effects 

  • According to the Environmental Protection Agency (EPA), Acetaldehyde can be listed as a probable human carcinogen.   
  • Long-term exposure to High levels of Acetaldehyde develops tumors in the respiratory tract of the workers.  
  • Long-term inhalation of Acetaldehyde can cause liver damage and nose, throat, and lung mucous damage of the workers.  

 

Environmental Hazards

 

  • Air pollution   

In industrial areas, Acetaldehyde is released from emissions and combustion processes, and it evaporates in the air quickly. Under sunlight, it reacts with other pollutants (such as nitrogen oxides and hydrocarbons) and forms ground-level ozone and smog. 

 

  • Soil &Water pollution   

 During production, storage, or transportation, accidental leaks and spills of Acetaldehyde lead to quick absorption into the soil or water body. It is a threat to the ecosystem and aquatic life. 

  

Acetaldehyde Exposure: Possible Sources 

 

  • Chemical industries   

Acetaldehyde plays a crucial role in producing Acetic acid. Acetic acid is used to manufacture vinegar and synthetic fiber.   

  

  • Perfumes industries  

Acetaldehyde is a fragrance ingredient in personal care products and cosmetic industries. It is used in the production of aroma compounds.  

  

  • Foods and beverage industries   

Acetaldehyde, which is a by-product of Ethanol, is used in the fermentation of beer and wine. Coffee and fermented products. In beverage production, this organic chemical is used as a flavouring agent.  

 

  • Paper & Pulp Industry  

Employees can be exposed to Acetaldehyde through inhalation during the chemical treatment of the wood fiber.  

  

  • Plastics & Rubber Industry  

Acetaldehyde plays an essential role in polymerization processes for synthetic rubber and plastics. Here, the workers have a high chance of contact with this chemical through skin contact, inhalation of vapor, etc.  

  

  • Fuel & Energy Industry  

Acetaldehyde works as an intermediate in the production of Bioethanol. Through inhalation, workers may be exposed to this chemical.   

  

Safety Measures to Lower Acetaldehyde Exposure    

Industries should implement safety measures for workers. Take a look at the safety guidelines designed for employees-  

  

For Workers/ Employees   

  • On-site screening devices should be used to detect Acetaldehyde in the air.   
  • Proper ventilation in the affected area is essential.   
  • Protecting the eyes and face with goggles and face shields is necessary.   
  • Workers should wear PPE clothes, masks, and chemical-resistant gloves.   
  • Removing contaminated clothes during the shift is necessary   
  • Washing hands after handling the Acetaldehydes is essential.   

  

Conclusion   

Acetaldehyde is a commonly used industrial chemical with serious health and environmental risks. The above discussion pointed out the potential hazards of this chemical through industrial exposure, as well as environmental pollution. By following safety guidelines and safety measures, workers and general people can reduce the harmful effects of Acetaldehyde.
