Summary
This Lancet Neurology review synthesises recent evidence on the relationship between environmental toxicants—including pesticides, heavy metals, and air pollutants—and Parkinson's disease risk. The authors examine both epidemiological associations and proposed biological mechanisms, as suggested by the 2020–2025 literature, and discuss prevention opportunities at individual and population levels. The paper appears to argue that environmental modification and toxicant reduction represent underutilised strategies in Parkinson's disease prevention.
UK applicability
UK practitioners and public health planners may find this review relevant to occupational health guidance (particularly for agricultural and industrial workers) and air quality policy, though the epidemiological evidence base may reflect exposure profiles in North America and Europe. The prevention framework could inform UK environmental health initiatives, though local exposure assessments would be required.
Key measures
Parkinson's disease incidence and prevalence; relative risk and odds ratios associated with environmental toxicant exposures; mechanistic pathways (neuroinflammation, mitochondrial dysfunction, protein aggregation)
Outcomes reported
The paper reviews evidence linking environmental exposures (pesticides, metals, air pollutants) to Parkinson's disease risk and identifies prevention opportunities. It synthesises recent epidemiological and mechanistic findings to inform clinical and public health strategy.
