我们对佛罗里达州彭萨科拉地区海湾和海湾中的蓝蟹(Callinectes Senidus)和牡蛎(Crassostrea Virgiica)的污染物进行了筛查水平评估。组织样本分析了17个二恶英/呋喃、12个二恶英类多氯联苯(DL-PCbs)同系物、汞和各种金属。污染物水平与根据美国环保局关于建立消费建议的建议计算的筛选值(SV)进行了比较。根据佛罗里达州的特定消费量(46克/天(-1))，所有采样地点都超过了二恶英/呋喃/DL-多氯联苯的SV(0.098 pg g(-1))。在选定地点的样本中，砷(无机)、汞、镉和锌的水平超过SVS，除汞外，这些地点通常位于已知污染地区的下游。我们还评估了食用这些物种对人类健康的潜在风险。食用螃蟹肝胰腺对人类健康的风险最大，这表明应避免直接或间接食用彭萨科拉湾地区任何地方采集的螃蟹的肝胰腺。(C)2006爱思唯尔有限公司。保留所有权利。
We conducted a screening level assessment of contaminants in blue crabs (Callinectes sapidus) and oysters (Crassostrea virginica) from bays and bayous in the Pensacola, FL area. Tissue samples were analyzed for 17 dioxins/furans, 12 dioxin-like PCB (DL-PCBs) congeners, mercury, and various metals. Contaminant levels were compared to screening values (SV) calculated using U.S. EPA recommendations for establishing consumption advisories. All sampling locations exceeded the SV (0.098 pg g(-1)) for dioxins/furans/DL-PCBs, based on a Florida-specific consumption rate (46 g day(-1)). Arsenic (inorganic), mercury, cadmium, and zinc levels exceeded SVs in samples from select locations, and with the exception of mercury, these locations were generally downstream of known contaminated areas. We also assessed potential human health risks from consumption of these species. Risks to human health were greatest from consumption of crab hepatopancreas, suggesting that consumption of hepatopancreas, whether directly or indirectly, from crabs collected anywhere in the Pensacola Bay region should be avoided.
