“…There are very few studies regarding organic contaminants in Antarctic lakes ([ 14 ] and references therein). Beside hydrocarbons of natural origin, petroleum hydrocarbon contamination, especially in localized areas (the Boulder Clay area is an example), is potentially the most likely source of anthropogenic pollution in Antarctic ecosystems [ 90 ]. According to Yao et al [ 91 ] the composition profiles of polycyclic aromatic hydrocarbons in Antarctic inland lakes clearly derive from local human activities (e.g., local oil spills), rather than long-range transport, with data that are corroborated by several reports on recent fuel spillage from ship and plane crash incidents.…”

The diversity and biotechnological potentialities of bacterial isolates from brines of three Antarctic lakes of the Northern Victoria Land (namely Boulder Clay and Tarn Flat areas) were first explored. Cultivable bacterial communities were analysed mainly in terms of bacterial response to contaminants (i.e., antibiotics and heavy metals) and oxidation of contaminants (i.e., aliphatic and aromatic hydrocarbons and polychlorobiphenyls). Moreover, the biosynthesis of biomolecules (antibiotics, extracellular polymeric substances and enzymes) with applications for human health and environmental protection was assayed. A total of 74 and 141 isolates were retrieved from Boulder Clay and Tarn Flat brines, respectively. Based on 16S rRNA gene sequence similarities, bacterial isolates represented three phyla, namely Proteobacteria (i.e., Gamma- and Alphaproteobacteria), Bacteroidetes and Actinobacteria, with differences encountered among brines. At genus level, Rhodobacter, Pseudomonas, Psychrobacter and Leifsonia members were dominant. Results obtained from this study on the physiological and enzymatic features of cold-adapted isolates from Antarctic lake brines provide interesting prospects for possible applications in the biotechnological field through future targeted surveys. Finally, findings on contaminant occurrence and bacterial response suggest that bacteria might be used as bioindicators for tracking human footprints in these remote polar areas.

“…Many of these studies have monitored the dispersal of produced water from offshore oil and gas installations, including alongside biota [137][138][139][140][141][142][143]. Other discharges monitored, resulted from paper mills (dioxins and endocrine disrupting compounds (EDCs)) [144,145], wastewater treatment (triclocarban, synthetic musk's, PCBs and pesticides) [146][147][148][149][150][151][152][153][154], smelters (dioxins) [114] and human settlements in Antarctica (PAHs) [155]. Dispersal of pollutants resulting from activities in the water column included, salvage operations (PAHs) [156], oil spills (PAHs) [157] and pisciculture (PCBs and pesticides) [158,159].…”

We comprehensively review the current state-of-the-art of environmental monitoring for hydrophobic organic contaminants in aqueous matrices using passive sampling devices. Principles of the theory of passive sampling are presented. Strategies for passive sampler design and operation, limitations in performance and data quality-assurance and quality-control are reviewed. Advances in applications of available passive sampling devices are extensively critiqued. Future trends and current challenges facing practitioners and barriers to further adoption of the devices are discussed.

“…Guo et al (2003) also reported BghiP as a source marker for gasoline emissions. Yao et al (2016) reported that 2-M-Nap indicates a petroleum-related source. The diagnostic ratio of BaP/(BaP + Chr) (= 0.49) has been used to identify diesel emissions (Khalili et al, 1995).…”

This study investigated PM 2.5 -bound polycyclic aromatic hydrocarbons (PAHs) in order to determine the seasonal changes in total benzo[a]pyrene equivalent (BaPeq) concentrations and to identify contamination sources by using a positive matrix factorization model, a conditional probability function, and characteristic ratios of PAHs in Hsinchu. The sampling period was from September 2014 to August 2015. PM 2.5 samplers equipped with 47-mm quartz membrane filters were operated at a flow rate of 16.7 L min -1 for 48 h. The concentrations of 20 PAHs were determined through gas chromatography-mass spectrometry. The results revealed the PM 2.5 , total PAHs, and BaPeq mass concentrations in the four seasons ranged from 4.91 to 58.5 µg m -3 , 0.21 to 8.08 ng m -3 , and 0.03 to 0.78 ng m -3 , respectively. The PM 2.5 , total PAHs, and BaPeq mass concentrations were in the order winter > autumn > spring > summer and exhibited significant seasonal variations. The carcinogenic potency of PAHs in winter was approximately 6.21 times higher than that in summer. The major BaPeq contributors were BaP, BbF, INP, and DBA. BaP accounted for 49.0% of BaPeq concentrations in PM 2.5 in all four seasons. The annual average lifetime excess cancer risk of PM 2.5 -bound PAHs (1.60 × 10 -5 ) was higher than that specified in the United States Environmental Protection Agency guidelines (10 -6 ). The two major sources were stationary emission sources and unburned petroleum and traffic emissions, which together accounted for 90.3% of PM 2.5 -bound PAHs.
