Recent advances in environmental analytical chemistry have identified the presence of a large number of chemicals of emerging Arctic concern (CEACs) being transported long range to the region. There has been very limited temporal monitoring of CEACs and it is therefore unknown whether they are of increasing or decreasing concern. Likewise, information on potential biological adverse effects from CEACs on Arctic wildlife is lacking compared with legacy persistent organic pollutants (POPs) found at levels associated with health effects in marine mammals. Hence, there is a need to monitor CEACs along with POPs to support risk and regulatory CEAC assessments. We suggest pan-Arctic temporal trend studies of CEACs in wildlife including the establishment of toxicity thresholds to evaluate their potential effects on populations, biodiversity, and ecosystem services.

环境分析化学领域的最新进展已经确定了许多新兴的北极关注化学品（CEAC）正在远距离运输到该地区。对CEAC的时间监控非常有限，因此未知它们是增加还是减少的关注。同样，与海洋哺乳动物对健康的影响相关的传统持久性有机污染物（POP）相比，缺少CEAC对北极野生生物的潜在生物不利影响的信息。因此，有必要对CEAC和POP进行监控，以支持风险和CEAC监管评估。我们建议对野生动植物中的CEAC进行北极时空趋势研究，包括建立毒性阈值以评估其对种群，生物多样性，
