Abstract

The release of heavy metals into the natural environment creates problems due to their persistence. They can accumulate in the food chain presenting a dangerous sign for ecosystems and human health. The metals in honey could be of agrochemical or industrial origin. Regular consumption of honey and bee products contaminated with various pollutants in high concentrations can cause serious health problems due accumulation of toxic substances in the body. In the current study, we aimed to determine the concentrations of chromium, cadmium, zinc, copper, lead and nickel in four types of honey (linden, acacia, rapeseed and polyfloral honey) and soil collected from three regions with different degrees of pollution. For the risk characterization, we used a new methodology that calculated the corrected estimated daily intake and the source hazard quotient for each metal and the adversity-specific hazard index. There was a strong influence of the degree of environmental pollution on the level of contaminants in the honey samples. In the case of a single chemical assessment, an HQ above 10 was obtained for Cd in linden, rapeseed and polyfloral honey from area 1 and an HQ above 1 was obtained for Cd in the other honey samples from the 3 areas, for Cu in all honey samples from all the 3 areas, for Pb in linden, rapeseed and polyfloral honey from area 1 and for Cr in linden honey for area 2. HIA calculated as a sum of all HQS of heavy metals in food reveals an increase and moderate risk for nephrotoxicity, bone demineralisation, cardiotoxicity, developmental toxicity, small decrease in body weight or body weight gain after consumption of honey impurified with heavy metals. A strict monitorization of heavy metals in honey samples from farmers should be done in order to protect the consumers.

摘要

重金属释放到自然环境中会因其持久性而引发问题。它们会在食物链中累积,对生态系统和人类健康构成危险信号。蜂蜜中的金属可能来源于农用化学品或工业。长期食用被各种高浓度污染物污染的蜂蜜和蜂产品,会因体内有毒物质的积累而导致严重的健康问题。在本研究中,我们旨在测定从三个污染程度不同的地区采集的四种蜂蜜(椴树蜜、刺槐蜜、油菜蜜和多花蜂蜜)及土壤中铬、镉、锌、铜、铅和镍的浓度。为进行风险特征描述,我们采用了一种新方法,该方法计算了每种金属的校正估计每日摄入量和源危险商以及特定逆境危险指数。环境污染程度对蜂蜜样品中的污染物水平有很大影响。在单一化学评估中,1区椴树蜜、油菜蜜和多花蜂蜜中的镉的危险商高于10,3个地区其他蜂蜜样品中的镉、所有3个地区所有蜂蜜样品中的铜、1区椴树蜜、油菜蜜和多花蜂蜜中的铅以及2区椴树蜜中的铬的危险商高于1。以食物中所有重金属的危险商总和计算的健康影响评估显示,食用被重金属污染的蜂蜜后,肾毒性、骨脱矿、心脏毒性、发育毒性、体重略有下降或体重增加的风险增加且为中度风险。为保护消费者,应严格监测来自农民的蜂蜜样品中的重金属。
