Abstract Economic development, including resource extraction, can cause toxic exposures that interact withendemic infectious diseases. Mercury is an immunotoxic metal used in the amalgamation of gold, resulting inboth occupational exposures and environmental pollution. A cross-sectional medical survey was conducted in1997 on 135 garimpeiros in Para, Brazil, because of their risks of both mercury exposure and malariatransmission. Mean levels of blood and urine mercury were well above non-exposed background levels. Twentysixsubjects had malaria parasitemia Health symptoms consistent with mercury exposure were reported, butneither symptoms nor signs correlated with mercury levels in blood or urine. We did not find a dose responserelationship between mercury exposure and likelihood of prevalent malaria infection, but there was a possiblereduction in acquisition of immunity that may be associated with conditions in gold mining, including mercury exposure...(AU)
