, People who are exposed to trichlorethylene (TCE) were six times more likely to develop Parkinson’s. The use of TCE in food and pharmaceutical industry has actually been banned since the 1970s, but this substance is still widely used in metal cleaning agents.
The team of researchers from the U.S., Canada, Germany and Argentina, led by Dr. Samuel Goldman of The Parkinson’s Institute in Sunnyvale, California identified six specific solvents are allegedly associated with Parkinson’s, two of which are TCE and PERC.
Researchers then analyzed 99 pairs of male twins, with one person stricken with Parkinson’s and her partner did not. This analysis of data obtained from military records of the National Academy of Sciences or the National Research Council World War II Veteran Twins Registry, founded in 1960.
Goldman and his team interviewed the twins about their work in detail with a questionnaire to measure the likelihood exposed to solvents have been determined.
Researchers have finally found exposure to TCE, PERC, and other chemicals which are known as carbon tetrachloride in a low level associated with an increased risk of disease neurodegenerative or damage the nerve.
“Our findings indicate a pause of up to 40 years between exposure to TCE and began thus potentially slowing the emergence of Parkinson’s disease before clinical symptoms appear,” said Dr.. Goldman was quoted as saying of dailymail, Tuesday (15/11/2011).
Disease Parkinson’s is caused by the loss of nerve cells in the brain and can cause tremor (shaking), slow motion, and cause disruption to talk.
TCE was used in adhesives, carpet cleaners, paint solution, and dry-cleaning solution. Until now, this substance is still used as a cleaning agent for metals. It is estimated that about 30 percent of U.S. drinking water supplies contaminated by these chemicals.
“This is the first study to show that the solvent TCE may be associated with an increased risk of Parkinson’s. It is important to highlight that the use of these solvents have been discontinued for safety reasons more than 30 years ago and protection in the workplace where chemicals are used has increased in recent years, “said Dr. Michelle Gardner, manager of research development at the Parkinson’s UK.
