“…Inter-estuarine differences observed in both OCPs and PCBs levels mainly reflected watershed land use and/or the vicinity of past or current industrial activity in SWA estuaries. In this context, SAM and BBL showed the highest OCP and PCBs levels in both matrixes, which would be related to the high industrial activity and continuous discharges via small tributaries of untreated effluents from high-density urban areas (Colombo et al, 2005;Tombesi et al, 2017). In contrast, MCH and QQG showed lower OCPs and PCBs levels in sediments than in polychaetes that could reflect more distant discharge sources and the dilution effect due to the increasing mixing with seawater (Van Ael et al, 2013).…”

“…Urban activities, petrochemical industries, maritime traffic and sewage discharges represent the main pollution threats. OCPs, petroleum-related hydrocarbons, heavy metals and organotin compounds were reported in sediments and biota from this SWA estuarine environment (Marcovecchio and Ferrer, 2005;Menone et al, 2006;Delucchi et al, 2007;Tombesi et al, 2017).…”

“…Intra-estuarine spatial differences observed in BBL sites would be related to the big area covered by BBL estuary (Piccolo and Perillo, 1999). The different anthropogenic impact and land use along such area would lead to varying levels of pollutants in its sediments (Tombesi et al, 2017).…”

“…Besides, many of these coastal environments serve as nesting and feeding habitats for many species, among other ecosystem services, being protected natural areas of regional and global concern (Kopprio et al, 2015). Several studies reported the occurrence of PCBs and OCPs in sediment, water and vertebrate species from SWA estuaries (Colombo et al, 2005;Gonzalez et al, 2013;Tombesi et al, 2017). However, few studies have focused on benthic invertebrate species (Menone et al, 2001(Menone et al, , 2006.…”

Southwest Atlantic (SWA) estuaries have been historically impacted by industrial and agricultural activities that represent an important source of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs). Intraspecific differences in OCPs and PCBs levels were evaluated in the benthic polychaete Laeonereis culveri from SWA estuaries (Samborombón; Mar Chiquita; Quequén Grande and Bahía Blanca) at different spatio-temporal scales. Regarding inter-and intra-estuarine spatial comparisons polychaetes showed significant differences in OCPs/PCBs levels (p < 0.05) being DDTs, endosulfan, penta-and hexa-CBs homologues the most representative compounds. Intra-estuarine comparisons also showed significant differences in terms of seasonality and body size (p < 0.05). OCPs/PCBs concentrations were negatively correlated with animal weight, but this covariable was not relevant on differences observed. OCPs/PCBs levels in polychaetes showed strong relationships with those of sediments, being suitable for estuarine biomonitoring studies. Seasonal and body-size differences found in OCPs and PCBs levels in tissues reveal the importance of these factors for intra-estuarine monitoring.

“…Fractions that demonstrate great bioactivities are then subjected to chemical analysis to identify bioactive compounds, or can be further fractionated if the fraction is still too complex. In general, liquid chromatography (LC) is used for fractionation of samples in EDA studies (Lubcke-von Varel et al, 2008;Weiss et al, 2009;Grung et al, 2011), but gas chromatography (GC) is the preferred separation technique for analysis of non-polar organic pollutants in environmental samples (Poster et al, 2006;Tombesi et al, 2017;Bjurlid et al, 2018). In recent years, a new GC-based fractionation platform with a post-column introduction of a trap solvent for fraction collection has been developed (Pieke et al, 2013;Jonker et al, 2016Jonker et al, , 2017.…”

To facilitate the study of potential harmful compounds sorbed to microplastics, an effect-directed analysis using the DR CALUX ® assay as screening tool for Aryl hydrocarbon receptor (AhR)-active compounds in extracts of marine deployed microplastics and chemical analysis of hydrophobic organic compounds (HOCs) was conducted. Pellets of three plastic polymers [low-density polyethylene (LDPE), high-density polyethylene (HDPE) and high-impact polystyrene (HIPS)] were deployed at Heron Island in the Great Barrier Reef, Australia, for up to 8 months. Detected AhR-mediated potencies (bio-TEQs) of extracted plastic pellets ranged from 15 to 100 pg/g. Contributions of target HOCs to the overall bioactivities were negligible. To identify the major contributors, remaining plastic pellets were used for fractionation with a gas chromatography (GC) fractionation platform featuring parallel mass spectrometric (MS) detection. The bioassay analysis showed two bioactive fractions of each polymer with bio-TEQs ranging from 5.7 to 14 pg/g. High resolution MS was used in order to identify bioactive compounds in the fractions. No AhR agonists could be identified in fractions of HDPE or LDPE. Via a multivariate statistical approach the polystyrene (PS) trimer 1e-Phenyl-4e-(1-phenylethyl)-tetralin was identified in fractions of HIPS and in fractions of the blank polymer of HIPS.

Environmental micro-organic pollutants accumulate in abiotic parts of the aquatic ecosystems. This study was aimed to make residue, source, and composition profiles of some micro-organic pollutants, consisting 16 polycyclic aromatic hydrocarbons (PAHs), seven polychlorinated biphenyls (PCBs), nine organochlorine pesticides (OCPs), and six polybrominated diphenyl ethers (PBDEs) in water and sediment from Kirmir Stream (Ankara, Turkey) between 2017 and 2018 as seasonal based. In water and sediment samples, total PAHs were determined to be 15.68 and 1216.19 μg/kg, respectively. Among the OCPs, only DDE was detected in sediment samples and its total concentration was 1768.92 μg/kg. Other OCPs, PCBs, and PBDEs were below the limit of quantification. Having molecular structure, found PAHs in water and sediments were originated from pyrolytic and petrogenic. Thus, this study will be very useful to provide background information for further studies on the contamination with environmental micro-organic pollutants in the region.
