Mercury exposure in a high fish eating Bolivian Amazonian population with intense small-scale gold-mining activities
(Taylor & Francis, 2009) F. Barbieri; Amandine Cournil; Jacques Gardon
Methylmercury exposure in Amazonian communities through fish consumption has been widely documented in Brazil. There is still a lack of data in other Amazonian countries, which is why we conducted this study in the Bolivian Amazon basin. Simple random sampling was used from a small village located in the lower Beni River, where there is intense gold mining and high fish consumption. All participants were interviewed and hair samples were taken to measure total mercury concentrations. The hair mercury geometric mean in the general population was 3.02 microg/g (CI: 2.69-3.37; range: 0.42-15.65). Age and gender were not directly associated with mercury levels. Fish consumption showed a positive relation and so did occupation, especially small-scale gold mining. Hair mercury levels were lower than those found in Brazilian studies, but still higher than in non-exposed populations. It is necessary to assess mercury exposure in the Amazonian regions where data is still lacking, using a standardized indicator.
Mercury Exposure in the Bolivian Amazon Basin: Comparison With the General Amazonian Situation
(Lippincott Williams & Wilkins, 2007) F. Barbieri; Jacques Gardon
ISEE-153 Objective: Methylmercury exposure in riverside communities through fish consumption and its risk to human health are sources of concern, and have been extensively studied in Brazilian Amazonia. Even though Brazilian and Bolivian Amazonian populations share similar environment and alimentary habits, there is an evident lack of data on mercury exposure outside Brazil. Thus, this study aimed to assess mercury exposure in the general population of a lower Beni River community (Cachuela Esperanza: 10° 32′ S 65° 35′ W). In addition, we reviewed published data on other Amazonian studies, looking forward to envision the Amazon basin general situation. Material and Methods: We used simple random sampling from the whole population, by performing a survey by private interview and taking hair samples to measure total mercury concentrations. These and the reviewed studies' results were sorted by hydrographic basin and target group and then represented on thematic Amazon basin maps. Results: Hair mercury levels in Cachuela Esperanza (geometric mean: 3.02 μg/g) were lower than those found in Brazilian studies. Nevertheless, this confirmed that the population was exposed. In comparison, the Madeira River basin showed hair mercury means ranging from 8 to 16 μg/g, whereas the Tapajós River basin showed hair mercury means ranging from 5 to 64 μg/g. Although there is a strong difference between basins, the spatial distribution of exposure levels does not display a clear pattern. Conclusions: The mercury exposure situation in Amazonia is very heterogenic. Besides, although certain Amazon populations were repeatedly studied, others remain without information on this problem. Thus, it would be necessary to assess mercury exposure in Amazonian regions still lacking in data, using a standardized indicator for the general population.
Toxic trace elements in maternal and cord blood and social determinants in a Bolivian mining city

This study assessed lead, arsenic, and antimony in maternal and cord blood, and associations between maternal concentrations and social determinants in the Bolivian mining city of Oruro using the baseline assessment of the ToxBol/Mine-Niño birth cohort. We recruited 467 pregnant women, collecting venous blood and sociodemographic information as well as placental cord blood at birth. Metallic/semimetallic trace elements were measured using inductively coupled plasma mass spectrometry. Lead medians in maternal and cord blood were significantly correlated (Spearman coefficient = 0.59; p < 0.001; 19.35 and 13.50 μg/L, respectively). Arsenic concentrations were above detection limit (3.30 μg/L) in 17.9% of maternal and 34.6% of cord blood samples. They were not associated (Fischer's p = 0.72). Antimony medians in maternal and cord blood were weakly correlated (Spearman coefficient = 0.15; p < 0.03; 9.00 and 8.62 μg/L, respectively). Higher concentrations of toxic elements in maternal blood were associated with maternal smoking, low educational level, and partner involved in mining.
