Perchloroethylene(CAS127-18-4), also known as tetrachloroethylene or PCE, is a colorless liquid that is widely used as a solvent in industrial settings and dry cleaning. It is also found in some consumer products, such as lubricants, adhesives, and sealants. While perchloroethylene has many useful applications, it also poses serious health risks to workers and the general public who are exposed to it.
According to the Centers for Disease Control and Prevention (CDC), exposure to perchloroethylene may cause irritation of the eyes, skin, nose, throat, and respiratory system. It may also affect the nervous system and cause symptoms such as headache, dizziness, nausea, fatigue, memory loss, and mood changes. Long-term exposure to perchloroethylene may damage the liver and kidneys and increase the risk of certain cancers.
Perchloroethylene exposure can occur through inhalation, ingestion, or skin contact.
The most common sources of exposure are occupational settings where perchloroethylene is used or stored, such as dry cleaning facilities, metal degreasing plants, and chemical manufacturing plants. Workers who handle perchloroethylene or work near machines that use it should wear appropriate personal protective equipment (PPE) and follow safety guidelines to prevent exposure.
Perchloroethylene exposure can also occur in the environment, where it can contaminate the air, water, and soil. Perchloroethylene can evaporate from spills or leaks and enter the indoor air of buildings. It can also leach from underground storage tanks or pipes and contaminate groundwater or surface water. People who live or work near sources of perchloroethylene pollution may be exposed to it through drinking water or breathing air that contains it.
The Environmental Protection Agency (EPA) has set standards and regulations to limit the amount of perchloroethylene(CAS127-18-4) that can be released into the environment and to protect human health from its effects. The EPA has also classified perchloroethylene as a likely human carcinogen based on evidence from animal studies and epidemiological studies.
Perchloroethylene exposure is a serious health concern that requires attention and action from both employers and employees who work with this chemical, as well as from environmental agencies and authorities who monitor its levels in the environment.
By reducing perchloroethylene(CAS127-18-4) use and emissions, improving ventilation and filtration systems, enforcing safety measures and regulations, and educating workers and the public about the dangers of perchloroethylene exposure, we can protect ourselves and our communities from this hazardous substance.
