Abstract

Honey has nutritional and therapeutic properties that bring various health benefits. Heavy metals are a major source of environmental pollution. The aim of this study was to determine mercury levels in honey samples from the Brazilian eastern amazon using a direct mercury analyzer (DMA) and human health risk assessment. The levels of Hg found in the samples ranged from 0.10 to 0.73 ng g^-1, except for 13 samples which were below the detection limit. The values estimates of average dietary exposure to total mercury in honey for adults were below the PTWI (4 µg kg^-1), thus presenting a low risk for the percentage of exposure, and the target hazard quotient (THQ) evaluation obtained values below 1. This study shown that Hg are accumulating in honey, presumably facilitated by dietary sources of the bees and direct environmental exposure.

巴西东亚马逊河蜂蜜中汞的测定和人类健康风险评估。

蜂蜜具有营养和治疗特性，带来各种健康益处。重金属是环境污染的主要来源。本研究的目的是利用直接汞分析仪（DMA）和人类健康风险评估，确定巴西东部亚马逊地区蜂蜜样品中的汞含量。除13个样本低于检出限外，其余样本的汞含量在0.10至0.73 ng g-1之间。成年人平均饮食中总汞的暴露值低于PTWI(4 µg kg-1)，因此暴露百分比的风险较低，目标危害商（THQ）评估的值低于1。这项研究表明，汞在蜂蜜中积累，可能是由蜜蜂的饮食来源和直接的环境暴露促进的。
