Parkinson's is a clinical syndrome with a group of characteristics 
findings. It is termed Parkinson's disease in the absence of a toxic or 
other known etiology. The major toxin associated with this syndrome is 
MTPT (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) which is an analog 
of meperidine, a synthetic opioid. MTPT is given intravenously to 
produce the lesions that cause Parkinson's.

There was a rash of Parkinson's in people from the era of the influenza 
pandemic of 1918  or so as they became older but this has become 
fleetingly rare at the present time.

There is a murky epidemiological suggestion that herbicide and pesticide 
exposure may increase the incidence of the disease. On the other hand, 
well water and living in the country also have the same degree of 
association.

Although not my specific area of expertise, so far as I know there is no 
suggested association of Parkinson's with darkroom chemicals in the 
medical literature .

Remember that 'post hoc ergo propter hoc' is a classic flaw in logical 
reasoning.
