摘要

This study evaluated the risk to human health from mercury exposure through fish consumption in three riverside populations: Children (CH, 2-15 years old), women of childbearing age (WCHA, 16-49 years old), and the rest of the population (RP) from the Urra reservoir area, Colombia. Questionnaire-based surveys were used to collect data and information about the weekly amount of fish consumed (WAFC) and the relative importance of each fish species in the diet of the study participants. There were no significant differences in WAFC between population groups. CH recorded the highest weekly intake of total Hg (WIT-Hg) (0.6-55.4 μg/kg body-weight/week), with significant differences (p ＜ .05) from WCHA (0.2-26.7 μg/kg bw/w) and RP (0.1-23.6 μg/kg bw/w). A high percentage (90%) of estimated WIT-Hg values exceeded the provisional tolerable weekly intake (PTWI) established in order to protect the embryo and fetus. Results suggested that sensitive subgroups, such as pregnant women or those who may become pregnant and young children should limit or avoid consumption of certain fish of higher trophic levels due to their high total Hg (T-Hg) concentrations (up to 2.73 μg/g). In sum, the high values of WIT-Hg in children and women of childbearing age revealed a worrying situation, which should be reviewed carefully in order to prevent a potential public health crisis.
