Online ahead of print.ABSTRACTArtisanal and small-scale gold mining (MAPEOs) are considered to be one of the main sources of mercury release into the environment. Considering the gold mining activities, this study evaluated the Hg concentration in 27 apiaries (Apis spp.) in the South of the Legal Amazon, Mato Grosso State, Brazil. A total of 243 samples distributed in 81 samples of bees, 81 beeswax, and 81 of honeys, collected between the months of July and November 2022, were analyzed. One bee sample showed Hg concentration above the limit of quantification (68.8 ng g-1), 27 samples were between the limit of detection and limit of quantification (15 samples of bees, 8 of wax and 4 of honey). In all study areas, trace levels of Hg concentration were detected, 12 near MAPEOs areas and 16 near crop areas. It recorded that the honeys analyzed in this study in Mato Grosso are not contaminated by Hg, not offering any risk to consumers of the product. It is noteworthy that the use of bioindicator tools such as bees, beeswax, and honey is effective in relation to Hg monitoring in apiaries. It can also infer that the implementation of beekeeping in areas that will go through experience the process of environmental recovery, after the mining exploitation, is feasible, in line with permanent biomonitoring of the region.PMID:39627500 | DOI:10.1007/s11356-024-35574-y
