“…These environments represent important sources of xenobiotics, including persistent organic pollutants (POPs) and, more specifically, polycyclic aromatic hydrocarbons (PAHs) [3]. These hydrophobic and liposoluble compounds are resistant to photochemical and biological degradation, which promotes their bioaccumulation in the adipose tissues of marine organisms [4]. In addition to POPs, metals, organotin and organometallic compounds and carbon monoxides (CO) damage water and sediment quality [3].…”

This work aims to assess the spatial and temporal variations of four biomarkers activities and to integrate their biological responses in a battery using the gastropod Phorcus turbinatus. The monitoring was carried out during the period between April 2014 and January 2015 at six stations along the northern and the northeastern coasts of Tunisia. The Fulton condition factor was estimated and the activities of catalase, acetylcholinesterase and glutathione-S-transferase were evaluated by spectrophotometry. A multi-biomarker battery approach was used to assess ecosystems’ condition and to identify environmental impacts on the organisms. The results suggest that the enzymatic activities of CAT and GST depend especially on seasons. As for AChE activity, it was similar between seasons and stations. The values of the integrated biological response were maximal at Jarzouna in summer and at Sidi Daoued in winter, indicating the presence of severe stressors suffered by the organisms. This perturbation may be due to the enrichment of the waters by xenobiotics, namely polycyclic aromatic hydrocarbons, insecticides, phosphate wastes, PCBs and pesticides. Thus, P. turbinatus seems to be a good bioindicator of chemical pollution, constituting an adequate tool for a bio-monitoring program.

We set out to determine whether infrared (IR) spectra of treated MCF-7 cells derived using attenuated total reflection Fourier-transform IR (ATR) microspectroscopy could be used to signature different exposures. Serum-lipid samples from residents living in an electronics waste (e-waste) dismantling region (Region E, n = 26) in the south of P.R. China or from a nearby region (Region S, n = 20) associated with the fishing industry were obtained. Following extraction, estrogen receptor-positive MCF-7 cells were treated for 24 h with < or = 5-mg lipid equivalent of individual extracts prior to ethanol fixation; subsequently, IR spectra of treated-cell populations were obtained using ATR microspectroscopy. Levels of organochlorinated and brominated compounds in parallel extracts were also determined. Principal component analysis (PCA) was employed to ascertain whether IR-spectral scores would cluster according to particular cohort. Scores plots following PCA highlighted significant clustering dependent on with which set of extracts MCF-7 cells were treated. This suggests marked differences in the cell-biochemical modulating effects induced by either set of extracts. Analysis of contaminant profiles in the extracts showed that polybrominated diphenyl ethers (PBDEs) accounted for 46.0% of total organohalogens and were higher than dichloro-diphenyl-trichloroethanes (DDTs) in Region E; DDTs were the major contaminants (85.2% of total contaminant load) compared to PBDEs (8.7%) in Region S. These results suggest that ATR microspectroscopy can segregate cell-biochemical effects as a consequence of very different exposure paradigms.
