“…To assess the effect of acute micro-PS exposure on the cellular pools of GSH and OSH in M. galloprovincialis, we exposed animals to two different concentrations of fluorescent microbeads for 24 h. In light of the scarcity of realistic data on the concentration of microplastics (<330 µm) in the Mediterranean Sea, these concentrations were chosen to reach detectable internalization in the different tissues of the mussels. Moreover, to the best of our knowledge, the micro-PS concentrations we chose are lower or in line with those reported in recent studies on M. galloprovincialis (Gonzàlez-Soto et al, 2022;Masìa et al, 2021;Trestrial et al, 2021;Wang et al, 2021). The acute exposure condition that we analyzed can be representative of punctual microplastics spillages or of a noncontinuous exposure scenario, simulating realistic irregular exposure to microplastic contaminations.…”

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.

“…These authors found the mean values of reactive oxidative species (ROS) content in Microplastics (MPs) may make it easier for organic contaminants like hydrocarbons present in oil to reach organisms by adsorbing onto MP surfaces. Gonzalez-Soto et al investigated mussels that were exposed for 21 days to 4.5 µm polystyrene microplastics alone or with sorbed water accommodated fraction (WAF) of crude oil in two dilutions (25% termed MP25, and 100% termed MP100) [75]. Microplastic exposure was found to alter glutathione transferase and isocitrate dehydrogenase enzymatic activity in the mussels' body, caused genotoxicity, increased oocyte atresia and basophilic cell volume in digestive tubules, and decreased absorption efficiency.…”

Microplastics are small pieces of plastic that are less than 5 mm in size and can be found in most environments, including the oceans, rivers, and air. These small plastic particles can have negative impacts on wildlife and the environment. In this review of the literature, we analyze the presence of microplastics in various species of wildlife, including fish, birds, and mammals. We describe a variety of analytical techniques, such as microscopy and spectrometry, which identify and quantify the microplastics in the samples. In addition, techniques of sample preparation are discussed. Summary results show that microplastics are present in all the wildlife species studied, with the highest concentrations often found in fish and birds. The literature suggests that microplastics are widely distributed in the environment and have the potential to affect a wide range of species. Further research is required to fully understand the impacts of microplastics on wildlife and the environment.

Sorption of Total Petroleum Hydrocarbons in Microplastics

As is the case for many others in the world, Mexican seas face complex pollution challenges; two of the contaminants that require special attention for their prevalence, possible chemical interactions, and relation to the country’s economy are leaked petroleum and microplastics (MP). This research assessed the sorption of total petroleum hydrocarbons (TPH) as fuel oil on microplastics in laboratory and field scenarios. Preliminary tests allowed the development and validation of a methodology to measure the sorbed fuel oil by Soxhlet extraction, with a 99.65% recovery rate. The amount of TPH sorbed in the lab followed the order LDPE > PS > PP > PVC > PET > HDPE, with the highest concentration found on LDPE. The sorption of fuel oil on microplastics is correlated to the surface area of the plastic particles and could also be related to the crystallinity of plastics. Sorption, for all plastics, was consistent with a second-order kinetic model. The analysis of field samples collected on beaches of the Gulf of Mexico varied from 1660 to 35,258 mg/kg MP. It must be noticed that, unlike others, this research quantified a family of contaminants, which could explain the high concentrations observed on microplastics.
