“…Our preliminary study suggests also that the evaluation of the toxicity mechanisms of a contaminant, especially in relation to oxidative stress, is hardly generalizable and is strongly linked to the stage of sexual maturity and sex. This phenomenon is in line with what is already described in other studies in relation to the influence of seasonality and consequently of the sex and sex‐related differences on different oxidative biomarker baseline levels in mussels for biomonitoring purposes (Balbi et al, 2017; Benito et al, 2019; Blanco‐Rayón et al, 2020; Grbin et al, 2019). Additional ecotoxicological studies are needed to characterize the modulation of antioxidant defences in marine organisms, improving our knowledge of how microplastics can affect marine life.…”

Over the last decade, the biological impact of microplastics in marine environments has become a serious global concern. Beyond their biological complexity, it is believed that many lethal and sublethal effects related to microplastic toxicity are triggered by oxidative stress and subsequently activated pathways. Thus, for marine organisms, having efficient mechanisms to fight the accumulation of oxidizing agents becomes indispensable to counteract the effects of microplastics. To date, our knowledge of the physiological effects of microplastics and the response of the antioxidant system in benthic species remains limited. The purpose of our study was to investigate the effects of short‐term exposure on the levels of two fundamental nonprotein antioxidants, glutathione (GSH) and ovothiol (OSH), in different tissues of Mytilus galloprovincialis. Our results show that the metabolism of OSH and GSH in mussels is clearly affected by acute microplastic exposure, and that the antioxidant response differs based on sex and reproductive stage. Indeed, although in the reproductive season the overall levels of GSH and OSH in different tissues significantly increase with respect to the control condition, the antioxidant response of the organisms, especially males, in the spent stage often exhibits a biphasic U‐shaped dose–response effect. Our study represents a pivotal investigation on the effects of microplastic exposure on the pools of two fundamental cellular antioxidants, with potential ecodiagnostic implications to forecast the stress status after exposure to microplastics, and highlights the possibility that the effects of these contaminants may vary over time based on the physiological condition of the animals.

With the continuous improvement of people’s demand for ecological environment quality, the research on ecological environment monitoring, analysis and evaluation had been paid more and more attention by relevant departments and personnel. Because the images collected by remote sensing technology were many and multi-source, the features extracted from remote sensing images using traditional methods had been difficult to meet the needs of related industry applications. Therefore, this paper made use of the advantages of PIE remote sensing image processing software in data analysis and processing, and put forward the research on ecological environment monitoring, analysis and evaluation methods. Firstly, on the basis of summarizing the concepts and related problems of ecological environment, this paper analyzed the processing methods of remote sensing data sources of ecological environment, and explained the evaluation standards and common methods of ecological environment. Secondly, the composition of PIE remote sensing image processing technology system and its application advantages were described, the common indicators and analysis methods of ecological environment monitoring were given, and the index system and model of ecological environment comprehensive evaluation were established. Finally, through the analysis of experimental cases, the results showed that the ecological environment monitoring analysis and evaluation method proposed in this paper was feasible. Compared with the traditional methods, the method proposed in this paper could objectively evaluate the ecological environment. This paper can not only provide support for the analysis and processing of remote sensing image data, but also provide an important reference for the application of remote sensing technology in the field of ecological environment.

“…The variability of these biological parameters can be attributed to extrinsic abiotic factors (e.g., temperature, salinity) or to intrinsic biotic factors (e.g. genotype, gender, age, reproduction) (Benito et al, 2019;Beyer et al, 2017;Freitas et al, 2019;Hines et al, 2007;Nam et al, 2017).…”

Biomonitoring of aquatic environments requires new tools to characterize the effects of pollutants on living organisms. Zebra mussels (Dreissena polymorpha) from the same site in north-eastern France were caged for two months, upstream and downstream of three wastewater treatment plants (WWTPs) in the international watershed of the Meuse (Charleville-Mézières "CM" in France, Namur "Nam" and Charleroi "Cr" in Belgium). The aim was to test 1 H-NMR metabolomics for the assessment of water bodies' quality. The metabolomic approach was combined with a more "classical" one, i.e., the measurement of a range of energy biomarkers: lactate dehydrogenase (LDH), lipase, acid phosphatase (ACP) and amylase activities, condition index (CI), total reserves, electron transport system (ETS) activity and cellular energy allocation (CEA). Five of the eight energy biomarkers were significantly impacted (LDH, ACP, lipase, total reserves and ETS), without a clear pattern between sites (Up and Down) and stations (CM, Nam and Cr). The metabolomic approach revealed variations among the three stations, and also between the upstream and downstream of Nam and CM WWTPs. A total of 28 known metabolites was detected, among which four (lactate, glycine, maltose and glutamate) explained the observed metabolome variations between sites and stations, in accordance with chemical exposure levels. Metabolome changes suggest that zebra mussel exposure to field contamination could alter their osmoregulation and anaerobic metabolism capacities. This study reveals that lactate is a potential biomarker of interest, and 1 H-NMR metabolomics can be an efficient approach to assess the health status of zebra mussels in the biomonitoring of aquatic environments.
