| مستخلص: | The Tapajós River basin in the Amazon region, Brazil is one of the most active gold mining areas in the world. In this study, we evaluated fish consumption habits and mercury exposure in 110 pregnant women in the city of Itaituba by measuring their total hair mercury concentrations. In addition, we investigated seasonal differences in mercury concentrations in two highly consumed piscivorous fish species, tucunaré (Cichla spp.) and pescada (Plagioscion squamosissimus). Total fish mercury concentrations (THg) during the dry season were 0.62±0.07 mg/kg for Cichla spp. and 0.73±0.08 mg/kg for P. squamosissimus. During the rainy season they were 0.39±0.04 and 0.84±0.08 mg/kg, respectively. Of our participants 44 % declared that they ate Cichla spp. and 67 % P. squamosissimus. Mean mercury concentration in their hair was 1.6±0.2 mg/kg and was above the US Environmental Protection Agency (US EPA) reference dose of 1 mg/kg in 48 % of them. Mean fish THg concentrations were also above the joint Food and Drug Administration and US EPA safety limit of 0.5 mg/kg for P. squamosissimus during both seasons and for Cichla spp. during the dry season only. These results show that pregnant women should avoid consumption of these piscivorous fish species during pregnancy and call for a regular programme to monitor Hg levels in that area. Slijev rijeke Tapajós u amazonskom području u Brazilu jedno je od najaktivnijih područja iskopavanja zlata na svijetu. U ovoj smo studiji procijenili navike konzumiranja ribe i razinu izloženosti metil-živi u 110 stanovnica Itaitube u peripartumu mjerenjem ukupne koncentracije žive u kosi (THg). Osim toga, istražili smo sezonske razlike u koncentracijama žive u dvjema najčešćim vrstama konzumnih piscivornih riba: tucunaré (Cichla spp.) i pescada (Plagioscion squamosissimus). U tih je ribljih vrsta THg tijekom sušne sezone iznosio 0,62±0,07 mg/kg za Cichla spp. te 0,73±0,08 mg/kg za P. squamosissimus. Tijekom kišne sezone koncentracija THg bila je 0,39±0,04 mg/kg za Cichla spp. I 0,84±0,08 mg/kg za P. squamosissimus. Sudionice su izjavile da su konzumirale Cichla spp. (44 %) i P. squamosissimus (67 %). Srednja koncentracija THg izmjerena u kosi bila je 1,6±0,2 mg/kg±std. Prosječna koncentracija THg u kosi bila je viša od referentne doze Američke agencije za zaštitu okoliša (krat. US EPA) koja iznosi 1 mg/kg, a čak u 48 % sudionica izmjerena je viša koncentracija. Također, srednja vrijednost koncentracija THg u ribi bila je iznad sigurnosne granice (0,5 mg/kg) za P. squamosissimus i tijekom sušne i kišne sezone, a za Cichla spp. samo tijekom sušne sezone. Rezultati istraživanja pokazuju da bi trudnice trebale izbjegavati konzumaciju ovih piscivornih ribljih vrsta. Stoga je razvidna potreba za redovitim programom praćenja razine žive na tom području. |
