> 6-fold increase in risk due to exposure Interestingly, the Guardian article does not cite a source for that claim, so it is impossible to evaluate it soundly. However, just above, it states: >> the number of people with Parkinson’s has increased 35% the last 10 years which is completely in line with the increase in at risk population + improved probability of diagnosis. That doesn't mean there is no link.
