Abstract:
In recent years, the climate change impact on the concentrations of persistent organic pollutants (POPs) has become a topic of notable concern. Changes in environmental conditions such as the increase of the average temperature, or the UV-B radiation, are likely to influence the fate and behavior of POPs, ultimately affecting human exposure. The state of the art of the impact of climate change on environmental concentrations of POPs, as well as on human health risks, is here reviewed. Research gaps are also identified, while future studies are suggested. Climate change and POPs are a hot issue, for which wide attention should be paid not only by scientists, but also and mainly by policy makers. Most studies reported in the scientific literature are focused on legacy POPs, mainly polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs) and pesticides. However, the number of investigations aimed at estimating the impact of climate change on the environmental levels of polycyclic aromatic hydrocarbons (PAHs) is scarce, despite of the fact that exposure to PAHs and photodegradation byproducts may result in adverse health effects. Furthermore, no data on emerging POPs are currently available in the scientific literature. In consequence, an intensification of studies to identify and mitigate the indirect effects of the climate change on POP fate is needed to minimize the human health impact. Furthermore, being this a global problem, interactions between climate change and POPs must be addressed from an international perspective.
摘要:
近年来,气候变化对持久性有机污染物(POPs)浓度的影响已成为值得关注的话题。平均气温升高等环境条件的变化,或者UV-B辐射,可能会影响持久性有机污染物的命运和行为,最终影响人类暴露。气候变化对持久性有机污染物环境浓度的影响的最新水平,以及人类健康风险,在这里审查。还发现了研究差距,同时建议未来的研究。气候变化和持久性有机污染物是一个热点问题,这不仅应该引起科学家的广泛关注,但也主要是政策制定者。科学文献中报道的大多数研究都集中在遗留持久性有机污染物上,主要是多氯二苯并对二恶英和二苯并呋喃(PCDD/Fs),多氯联苯(PCBs)和农药。然而,旨在评估气候变化对多环芳烃(PAHs)环境水平影响的调查数量很少,尽管暴露于PAHs和光降解副产物可能会导致不利的健康影响。此外,科学文献中目前没有关于新出现的持久性有机污染物的数据.因此,需要加强研究,以确定和减轻气候变化对持久性有机污染物命运的间接影响,以最大程度地减少对人类健康的影响。此外,这是一个全球性的问题,必须从国际角度解决气候变化与持久性有机污染物之间的相互作用。
