Studies of fish consumption often focus on awareness of and adherence to advisories, how much fish people eat, and contaminant levels in those fish. This paper examines knowledge and accuracy of risks and benefits of fish consumption among fishers and other recreationists in the New York Bight, indicative of whether they could make sound dietary decisions. While most respondents knew about health risks (70%) and benefits (94%) of consuming fish, far fewer could name specific risks and benefits. Less than 25% of respondents mentioned mercury and less than 15% mentioned that pregnant women and children were at risk. Far fewer people mentioned polychlorinated biphenyls (PCBs). Nearly 70% said it was healthy to eat fish, and 45% were aware that fish were rich in healthful oils. Despite the lack of details about what specific risks and benefits of fish, well over a third did not feel they needed more information. Other respondents had basic questions, but did not pose specific questions about the fish they caught or ate that would have clarified their individual risk-balancing decisions. Knowledge of which fish were high in contaminants did not match the mercury or PCB levels in those fish. There was a disconnect between the information base about specific risks and benefits of fish consumption, levels of mercury and PCBs in fish, and the respondent's desire for more information. These data indicate that respondents did not have enough accurate information about contaminants in fish to make informed risk-balancing decisions.
对鱼类消费的研究通常聚焦于对相关建议的认知与遵循情况、人们食用鱼类的量以及这些鱼类中的污染物水平。本文考察了纽约湾渔民和其他休闲垂钓者对鱼类消费风险与益处的了解程度及准确性,以此表明他们是否能够做出合理的饮食决策。虽然大多数受访者知晓食用鱼类的健康风险(70%)和益处(94%),但能说出具体风险和益处的人要少得多。不到25%的受访者提到了汞,不到15%的受访者提到孕妇和儿童面临风险。提到多氯联苯(PCBs)的人更少。近70%的人表示食用鱼类有益健康,45%的人意识到鱼类富含有益健康的油脂。尽管对于鱼类具体的风险和益处缺乏细节信息,但超过三分之一的人并不觉得自己需要更多信息。其他受访者有一些基本问题,但没有针对他们所捕获或食用的鱼类提出具体问题,而这些问题本可以澄清他们个人的风险权衡决策。对于哪些鱼类污染物含量高的认知与这些鱼类中的汞或多氯联苯水平不相符。关于鱼类消费具体风险和益处的信息库、鱼类中汞和多氯联苯的水平以及受访者对更多信息的需求之间存在脱节。这些数据表明,受访者没有足够准确的关于鱼类污染物的信息来做出明智的风险权衡决策。
