For people in many professions, exposure to chemicals such as paint and certain cleaners are a major part of everyday life.
Now, new research shows that people who are exposed to fumes from chemical solvents for long periods of time may have a higher risk for memory loss and other brain issues as they enter retirement age.
Solvents are substances used to dilute or dissolve other substances. They include chemicals such as degreasers, metal cleaners, adhesives, paint and lubricants. Contact with solvents in the workplace is common in the United States and other industrialized countries.
The study analyzed more than 2,000 French retirees. Researchers found that people who had been exposed frequently to the solvents had the highest risk for thinking and memory deficits, compared with those with no exposure to solvents.
Participants in the study took eight thinking and memory tests about 10 years after retiring. The tests revealed that 59 percent of these people showed some sort of cognitive impairment in one to three of the tests. Twenty-three percent showed impairment in four or more tests.
Also, depending on each participant’s level of exposure to solvents, the test results show that time might not improve the effects on thinking and memory. As workers wait longer to retire, those who are exposed to solvents face a longer exposure time, increasing their risks.
In workplaces where using solvents is absolutely necessary, know the health risks involved and make sure to receive proper training. In addition, employers should ensure that work areas are well-ventilated. Also, it’s important to wear protective clothing. Be sure to wash your hands before eating, drinking, smoking or using the bathroom after coming into contact with the solvent.
Even though exposure to fumes may be unavoidable, there are ways to minimize the long-term effects.
