บทคัดย่อ (EN): Mercury (Hg) emitted from open burning of amalgam in gold recovery at artisanal small scale gold mine in Buladu Village attributed in Hg contamination in terrestrial systems in surrounding area.Objective: to investigate Total mercury (THg) concentrations in dry deposit, surface soil and foodstuffs were investigated as well as the potential environmental and health risks in the area of concern.Results: The concentrations of THg in Deme, Buladu and Wubudu Villages in dry deposit were 136, 501 and 326 μg -1 m 2 /day, in surface soil were 2184, 4465 and 4597 μgkg -1 dw, in meat and seed of cocoa (Theobroma cacao) were 975, 1212, 1335 μg kg -1 ww and 1189, 2014, 2973 μgkg -1 ww, in cocoa (Cocos nucifera L.) meat and milk were 1125, 1348, 1581μg kg -1 ww, and 235, 405, 477 μg kg -1 ww and in corn were 170, 240 and 327 μgkg-1ww in summer season, respectively. Likewise, in rainy season, THg concentrations in surface soil were 1189, 2014 and 2973 μgkg-1dw, in cocoa meat and seed were 454, 867, 728 μgkg-1ww and 453, 528, 459 μgkg -1 ww, in coconut meat and milk were 357, 477, 405 kg -1 ww and 201, 356, 310 μgkg-1ww and in corn were 124, 310 and 226 μgkg-1ww, respectively. The value of hazard quotient (HQ) for dry deposit, surface soil and shallow well water were at risks with the values of 10, 46 and 1.7, respectively, whereas target hazard quotient (THQ) values of edible part of cocoa, coconut and corn were very low and not at risk with the values of 0.2, 0.2, 0.1, respectively.Conclusion: Environmental status of terrestrial systems in Buladu gold mine and vicinity area were at risk while the local foodstuffs were still safe for consumption. © 2014 AENSI Publisher All rights reserved.
