There is no simple rule to earmark occupational carcinogens as opposed to nonoccupational ones.
Neither research on new wireless devices like mobile communication, nor research on occupational exposure is sufficient to rule out chronic health effects from low exposures.
We observed no evidence of confounding of any PNS measure by these occupational exposures; however, we cannot rule out the possibility of confounding by unmeasured neurotoxicants.
Our case studies indicate a need for an early and comprehensive prevention system including dedicated rules for the occupational hygiene and biomonitoring procedures.
Since arsenic containing pesticides were not very common in these areas and arsenic mining was not done in this region, occupational exposure to arsenic was ruled out.
