Bismuth shotshells have been approved as a "nontoxic" alternative to lead in North America. Approval was based on a limited number of studies; even background levels of bismuth in wildfowl were unknown. We report on the concentration of bismuth (and lead) in muscle and liver tissues of wildfowl (Anas platyrhynchos, Anas acuta, Anas crecca, Branta canadensis, Chen caerulescens) harvested with lead shotshell. Average liver-bismuth levels detected in the present study (e.g., teal, 0.05 microg/g dw; mallard, 0.09 microg/g dw) suggest analytical error in other studies examining the effects of bismuth in birds. Significant positive relationships between bismuth- and lead-tissue levels for muscle when all species were combined (and for B. canadensis and C. caerulescens separately) can be explained by noting that bismuth is a contaminant of lead. Thus, more research is recommended to confirm the appropriateness of bismuth as a "nontoxic" shot alternative.
铋霰弹在北美已被批准作为铅的“无毒”替代品。其批准基于数量有限的研究；甚至野生禽类体内铋的背景水平也不清楚。我们报告了用铅霰弹猎获的野生禽类（绿头鸭、针尾鸭、绿翅鸭、加拿大黑雁、雪雁）肌肉和肝脏组织中铋（和铅）的浓度。本研究中检测到的平均肝脏铋水平（例如，绿翅鸭，0.05微克/克干重；绿头鸭，0.09微克/克干重）表明其他研究在检测铋对鸟类影响时存在分析误差。当所有物种合并（以及分别对加拿大黑雁和雪雁）时，肌肉中铋和铅组织水平之间存在显著正相关关系，这可以通过注意到铋是铅的污染物来解释。因此，建议进行更多研究以确认铋作为“无毒”霰弹替代品的适用性。
