“…This information is like what has been reported elsewhere. Low levels of PCBs, DDT, and HCB indicate that the control of production and emissions regulation of these pollutants had has a result in the world.Declining trends of α-HCH, γ-HCH, chlordane, and DDT, including α-endosulfan from analysis of Arctic air at eight sites over 25 years of monitoring (AMAP program) were previously discussed byWong et al (2021). However, the authors of the present work observed a slight increase in PCBs, which was attributable to warming in the region and continued primary emissions at source.In short, there are controversial results regarding the global distribution and concentration of OCPs and PCBs.…”

Pollution levels of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were investigated in the El Sol and the La Luna alpine lakes. The lakes are located in central Mexico, in the crater of the Nevado de Toluca volcano. The El Sol and the La Luna lakes are extremely relevant in Mexico and in the world because they are recognized as pristine regions and environmental reservoirs.Samples of atmospheric aerosol, sediment, plankton, and Tubifex tubifex were collected at three different sample locations for three years (2017, 2018, and 2019) at three different times of year, meaning that the weather conditions at the time of sampling were different. Pollutants were analysed by gas chromatography-mass spectrometry with negative chemical ionisation (GC-MS/NCI).Endosulfan was the most frequent and abundant pollutant, showing the highest peaks of all. Atmospheric aerosol revealed Σ 2 = 45 pg/m 3 , including α and β, while sediment lakes displayed α, β and endosulfan sulphate as Σ 3 = 1963 pg/g, whereas plankton and Tubifex tubifex showed Σ 2 = 576 pg/g and 540 pg/g for α and β respectively. Results of endosulfan ratios (α/β) and (α-β/endosulfan sulphate) suggest that both fresh and old discharges continue to arrive at the lakes This study shows for the rst time the pollution levels of OCP and PCB in high mountain lakes in Mexico. These results that must be considered by policy makers to mitigate their use in the various productive activities of the region.

“…To achieve these goals, it is necessary to develop technologies and methods of modern environmental engineering. The scientific community with the assistance of the international organization Arctic Council has developed and implemented the Arctic Monitoring and Assessment Program (AMAP) [13].

Conceptual foundations of legal support for engineering in Arctic studies of climatic changes

2021

View full text Add to dashboard Cite

The article is devoted to the problems of the development of the Arctic as a territory of international cooperation, taking into account the national interests of individual states. The specificity of geopolitical, social, economic, and climatic conditions determines the need to develop conceptual foundations of legal support for the implementation of environmental engineering processes at the development of the Arctic and research on climatic changes of the region. The article analyzes the main strategic and legal documents regulating the implementation activities in relation to the technical and technological support in the question of the development of the Arctic territories and the preservation of climatic stability. The options for creating an adequate system of convergence of national and international legal regulation in the field of determining anthropogenic pollutants and fixing key indicators of the state of the Arctic environment are detailized and characterized. The scientific substantiation of the causes and consequences of climate change in the Arctic ecological systems is given. The advantages of scientific research with the use of modern engineering and digitalization methods, as well as the usage of information and communication technologies for the prompt exchange of environmentally significant information, are revealed. It is noted that thе most topical issues, the national strategies for the development of the Arctic zones of the Russian Federation, Denmark, Norway, and Canada are of a similar nature. They have common approaches to the preservation of vulnerable Arctic ecological systems and the conceptual foundations of legal support for engineering in Arctic scientific research in the field of climate change and conservation.

“…Moreover, the here-reported study allows the influence of the middle-latitude sources (LRAT) to be distinguished from local sources. This knowledge is essential for authorities working on national and regional regulatory monitoring and remediation strategies and might further provide confidence for choosing new candidates to be routinely measured (Wong et al, 2021) in densely populated areas and in the Arctic (Röhler et al, 2020). As increased shipping, industrial development, and further urbanization of local settlements are predicted to substantially increase in the Arctic due to climate change and declining sea ice cover, it is crucial to stay alert to the levels of the emerging contaminants primarily emitted after fossil fuel burning such as the PACs.…”

Polycyclic aromatic hydrocarbons (PAHs) and their nitrated and oxygenated derivatives in the Arctic boundary layer: seasonal trends and local anthropogenic influence

et al. 2021

Abstract. A total of 22 polycyclic aromatic hydrocarbons (PAHs), 29 oxy-PAHs, and 35 nitro-PAHs (polycyclic aromatic compounds, PACs) were measured in gaseous and particulate phases in the ambient air of Longyearbyen, the most populated settlement in Svalbard, the European Arctic. The sampling campaign started in the polar night in November 2017 and lasted for 8 months until June 2018, when a light cycle reached a sunlit period with no night. The transport regimes of the near-surface, potentially polluted air masses from midlatitudes to the Arctic and the polar boundary layer meteorology were studied. The data analysis showed the observed winter PAC levels were mainly influenced by the lower-latitude sources in northwestern Eurasia, while local emissions dominated in spring and summer. The highest PAC concentrations observed in spring, with PAH concentrations a factor of 30 higher compared to the measurements at the closest background station in Svalbard (Zeppelin, 115 km distance from Longyearbyen), were attributed to local snowmobile-driving emissions. The lowest PAC concentrations were expected in summer due to enhanced photochemical degradation under the 24 h midnight sun conditions and inhibited long-range atmospheric transport. In contrast, the measured summer concentrations were notably higher than those in winter due to the harbour (ship) emissions.
