We exploit variation in the composition of local fish catches around the time of birth using administrative and census data on adult cognitive test scores, schooling attainment, and occupation among coastal populations in Colombia to estimate the causal effects of early-life consumption of methylmercury (MeHg) and DHA, elements contained in fish, on cognitive development. Using an IV strategy based on an equilibrium model of fish supply that exploits time-series variation in oceanic SST…

Rice life cycle-based global mercury biotransport and human methylmercury exposure

Rice could be a significant global dietary source of human methylmercury exposure, especially in South and Southeast Asia, and anthropogenic biovectors such as crops should be considered in the global mercury cycle.
