Answer

Arsenic exposure may be a factor in the development of bladder cancer. Results of a population-based case-control study in Maine, New Hampshire, and Vermont support an association between low-to-moderate levels of arsenic in drinking water and bladder cancer risk in those states, where incidence rates of bladder cancer have long been about 20% higher than in the United States overall. [25] A likely source of the arsenic is residue of arsenic-based pesticides, which were used extensively on crops such as blueberries, apples, and potatoes in that region from the 1920s through to the 1950s.
