Implication

Cohort study reveals an increased risk of bladder cancer from low-level well water arsenic exposure, suggesting even trace concentrations may elevate malignancy risk.

Key Points

To evaluate arsenic concentrations in drilled well water and examine their association with the risk of bladder and kidney cancers.
Sampled drilled wells used during 1967–1980 by a nationwide Finnish cohort (N = 144,627) living outside municipal drinking-water networks.
Assessed exposure metrics (well concentration, daily dose, and cumulative dose) across 61 bladder cancer cases, 49 kidney cancer cases diagnosed between 1981 and 1995, and 275 age- and sex-balanced reference subjects.
Kidney cancer risk was not statistically significantly associated with any of the evaluated arsenic exposure indicators.
Bladder cancer risk increased with arsenic exposure 3 to 9 years prior to diagnosis, yielding risk ratios of 1.53 (95% CI, 0.75–3.09) for 0.1–0.5 µg/L and 2.44 (95% CI, 1.11–5.37) for ≥0.5 µg/L relative to <0.1 µg/L.
