The main objective of this study was to investigate possible temporal trends of persistent organic pollutants (POPs) and mercury in eggs of herring gulls (Larus argentatus), black-legged kittiwakes (Rissa tridactyla), common guillemots (Uria aalge) and Atlantic puffins (Fratercula arctica) in Northern Norway. Eggs were collected in 1983, 1993 and 2003. Egg concentrations of POPs (PCB congeners IUPAC numbers: CB-28, 74, 66, 101, 99, 110, 149, 118, 153, 105, 141, 138, 187, 128, 156, 157, 180, 170, 194, 206, HCB, alph-HCH, beta-HCH, gamma-HCH, oxychlordane, trans-chlordane, cis-chlordane, trans-nonachlor, cis-nonachlor, p,p'-DDE, o,p'-DDD, p,p'-DDD, o,p'-DDT and p,p'-DDT) and mercury were quantified. Generally, POP levels decreased between 1983 and 2003 in all species. No significant temporal trend in mercury levels was found between 1983 and 2003.
本研究的核心目标为探究挪威北部地区银鸥(Larus argentatus)、黑脚三趾鸥(Rissa tridactyla)、普通海鸠(Uria aalge)以及大西洋海鹦(Fratercula arctica)四种海鸟卵中持久性有机污染物(Persistent Organic Pollutants)与汞的潜在时间变化趋势。研究样本分别于1983年、1993年及2003年采集。本研究对卵样中持久性有机污染物(多氯联苯同系物的IUPAC编号为CB-28、74、66、101、99、110、149、118、153、105、141、138、187、128、156、157、180、170、194、206;六氯苯(HCB)、α-六氯环己烷(alph-HCH)、β-六氯环己烷(beta-HCH)、γ-六氯环己烷(gamma-HCH)、氧氯丹、反式氯丹、顺式氯丹、反式九氯、顺式九氯、p,p'-二氯二苯二氯乙烯(p,p'-DDE)、o,p'-二氯二苯二氯乙烷(o,p'-DDD)、p,p'-二氯二苯二氯乙烷(p,p'-DDD)、o,p'-二氯二苯三氯乙烷(o,p'-DDT)及p,p'-二氯二苯三氯乙烷(p,p'-DDT))与汞的浓度进行了定量分析。整体而言,1983年至2003年间所有受试物种体内的持久性有机污染物水平均呈下降趋势;同期汞浓度未观测到显著的时间变化趋势。
