The presence of heavy metals in big game meat may pose a risk to human health. The main objective of this paper is to carry out a risk assessment study (using a probabilistic and point-estimate approach) of lead intake by consumption of red deer and wild boar meat in Southern Spain based on Spanish data collected in the period 2003-2006. In general, the concentration levels found for wild boar meat (mean = 1291 µg kg(-1)) were much higher than those observed in red deer meat (mean = 326 µg kg(-1)). The results from a point-estimate risk assessment showed that the estimated average intake of lead among different exposure scenarios varied from 0.1 to 6.5 and from 0.3 to 38 µg kg(-1) week(-1) for red deer and wild boar meat, respectively; and from 0.3 to 35 µg kg(-1) week(-1) for individuals consuming both red deer and wild boar meat, and that the estimated intake of lead by consumption of big game meat differed significantly between hunters and non-hunters, it being higher for hunters. Besides this, results from the probabilistic risk assessment study corroborated the fact that risk is greater in hunter populations, reaching a maximum in individuals consuming only wild boar and both types of meat, with 0.4% and 0.2% of the population above the provisional tolerable weekly intake (PTWI), respectively. Likewise, the hunter populations consuming wild boar and both types of big game meat (red deer and wild boar meat) were exposed to the maximum lead level (56 µg kg(-1) week(-1)), which corresponded approximately to 224% of the PTWI. Further data and studies will be needed to give a complete risk estimation in which it will be crucial to consider the contribution to the lead intake level of other foods in the diet of both population groups.
重金属在大猎物肉中的存在可能对人类健康构成威胁。本文的主要目的是基于西班牙在 2003-2006 年期间收集的数据，采用概率和点估计方法，对西班牙南部红鹿和野猪肉消费导致的铅摄入量进行风险评估研究。一般来说，野猪肉中的浓度水平（均值=1291µg/kg）远高于红鹿肉中的浓度水平（均值=326µg/kg）。点估计风险评估的结果表明，在不同的暴露情景下，不同个体对铅的平均估计摄入量从 0.1 到 6.5 微克/千克/周不等，从 0.3 到 38 微克/千克/周不等，分别来自红鹿和野猪肉的摄入量；食用红鹿和野猪肉的个体摄入量从 0.3 到 35 微克/千克/周不等；食用大猎物肉的个体摄入量在猎人组和非猎人组之间有显著差异，猎人组更高。此外，概率风险评估研究的结果证实，猎人人群的风险更大，仅食用野猪和两种肉类的个体的风险达到最高，分别有 0.4%和 0.2%的人群超过暂定每周耐受摄入量（PTWI）。同样，食用野猪和两种大猎物肉（红鹿和野猪肉）的猎人人群暴露于最大的铅水平（56 微克/千克/周），大约相当于 PTWI 的 224%。需要进一步的数据和研究来进行全面的风险评估，其中考虑两组人群饮食中其他食物对铅摄入量的贡献至关重要。
