Common contaminant 'increases Parkinson's risk'RSS Feed

Risk of developing Parkinson's disease could be higher in those exposed to trichloroethylene, with the contaminant thought to increase the chances of developing the brain injury.

The hazardous organic contaminant, which is found in soil, groundwater and air, was found to be significantly associated with increased risk of Parkinson's, according to a study published in journal annals of Neurology.

A team of scientists questioned 99 sets of twins, one of who had Parkinson's disease and the other who did not, about their lifetime occupations and hobbies.

Lifetime exposure to six specific solvents previously linked to the condition was inferred for each job and hobby.

Those with a lifestyle that had seen them more exposed to trichloroethylene were at more than a six-fold increased risk of developing Parkinson's.

"Our study confirms that common environmental contaminants may increase the risk of developing PD, which has considerable public health implications," commented Dr Samuel Goldman, one of the study leaders.
