Colombia is one of the largest per capita mercury polluters in the world as a consequence of its artisanal
gold mining activities. The severity of this problem in terms of potential health effects was evaluated by
means of a probabilistic risk assessment carried out in the twelve departments (or provinces) in Colombia
with the largest gold production. The two exposure pathways included in the risk assessment were inhalation
of elemental Hg vapors and ingestion of fish contaminated with methyl mercury. Exposure parameters
for the adult population (especially rates of fish consumption) were obtained from nation-wide
surveys and concentrations of Hg in air and of methyl-mercury in fish were gathered from previous scientific
studies. Fish consumption varied between departments and ranged from 0 to 0.3 kg d?1. Average
concentrations of total mercury in fish (70 data) ranged from 0.026 to 3.3 lg g?1. A total of 550 individual
measurements of Hg in workshop air (ranging from | |
