Summary: Several international organisations have recommended the use of bioindicators to improve the evaluation of ecological risk in marine ecosystems. In this study, wild mussels were collected from thirty sampling points along the Asturias coastline and analyzed to identify the relationship between metal concentrations in mussel tissues and the geological and environmental conditions of the coastal area. The study revealed concentration trends for different metals and correlations between them. The mussels also showed natural defense against certain metals. Cluster analysis of the samples grouped them based on the sources of the metal concentrations. Both anthropic and natural sources have led to an increase in metal loads in mussels, sometimes exceeding international environmental criteria.

Summary: The study found that HMs levels in sediments in karst areas are low, but Cd and Zn concentrations in fish are significantly higher than the soil baseline. Most HMs are present in the residual fraction, with very low proportions of exchangeable fractions that could impact bioaccumulation. Some fish samples exceeded the maximum recommended limit for certain HMs. Environmental factors have a significant impact on HMs bioconversion, especially the proportions of different HM species.

Summary: Serpentine soils, rich in heavy metals and poor in nutrients, limit plant species' performance and survival. A pot experiment was conducted to compare the development features of non-serpentine species Berkheya radula in serpentine soils. Results showed enhanced productivity and photosynthesis in serpentine treatments compared to the control. Development features were correlated with heavy metals and macronutrients in the leaves. The study suggests that B. radula exhibits metallophyte characteristics and the potential for bioaccumulation and phytoremediation is shared between serpentine and non-serpentine species in this genus.

Summary: Widespread heavy metal pollution poses severe health risks globally. Curcumin has a broad protective effect against various heavy metals. However, its specificity and antagonistic ability against different heavy metals remain largely unknown. This study systematically compared the detoxification efficiency of curcumin on the cytotoxicity and genotoxicity caused by cadmium, arsenic, lead, and nickel. The results showed that curcumin exhibited different antagonistic capacities against these heavy metals, with stronger protection against cadmium and arsenic. Curcumin also demonstrated better detoxification ability against heavy metal-induced genotoxicity than cytotoxicity.

Summary: Accumulation of heavy metals in fish tissues is crucial for monitoring the health of aquatic ecosystems, especially in edible parts of fish. Studies have shown that fish collected from the Persian Gulf have the highest concentrations of heavy metals, followed by species from the Caspian Sea. Fish species inhabiting the lower zone of the water column and those that are carnivorous or omnivorous tend to have higher levels of heavy metals, with the liver being the main accumulator organ.

Summary: Wastewater treatment plants are a significant source of microplastics discharged into the environment, with their characteristics in different environmental matrices still largely unknown. Most microplastics in water samples are composed of PET, PS, PP, and PE, with a significant proportion being removed during primary and secondary treatment stages, and MBR being the most efficient tertiary treatment technology. The majority of microplastics removed during wastewater treatment end up in sewage sludge and are released into the environment via sludge applications.

Summary: The presence of natural organic matter (NOM), modeled by humic acid (HA), can mitigate the acute toxicity of amino-functionalized polystyrene nanoplastics (PS-NH2) to green microalga Chlorella vulgaris, reducing cellular aggregation and cell size reduction. Higher concentrations of HA are more effective in reducing the toxicity of PS-NH2. The formation of cellular aggregates under the influence of PS-NH2 is likely related to the electrostatic attraction between the positively charged surfaces of the particles and the negatively charged polysaccharide walls of C. vulgaris.

Summary: Microplastics have gained attention due to their excessive spread in the environment, especially in water ecosystems. This study investigated the adsorption of iron and copper nanoparticles on three different microplastics (PP, PVC, and PS). Parameters such as pH, contact duration, and initial nanoparticle concentration were examined. The adsorption was measured using atomic absorption spectroscopic analysis. The maximum adsorption occurred at pH = 11, after 60 minutes of contact, and at an initial concentration of 50 mg L-1. Scanning electron microscope (SEM) images showed different surface characteristics of the microplastics. Fourier transform infrared analysis (FTIR) indicated physical adsorption, and X-ray energy diffraction spectroscopy (EDS) confirmed the adsorption of iron and copper nanoparticles. Freundlich adsorption isotherm and pseudo-second-order kinetics were found to fit the adsorption data better. The adsorption ability of microplastics ranked as PVC > PP > PS, with copper nanoparticles being adsorbed more than iron nanoparticles in general.

Summary: This study measured the concentrations of Cd, Ni, and Pb in the liver and muscle tissues of two fish species, Barbus grypus and Tenualosa ilisha, collected from the Karoon River in Iran. The potential human health risks associated with these heavy metals were evaluated using EDI, THQ, HI, and TR. The results emphasize the importance of habitat and feeding habits in the uptake of HMs by these fish species. The study found that the EDI for all HMs exceeded the RfDo provided by the USEPA, indicating potential safety concerns for human consumption. The THQ values were within the permissible limit, while HI values indicated non-carcinogenic risks for consumers. The TR values for Pb were within an acceptable range for both species.

Summary: The presence of microplastic particles has been reported worldwide, even in remote areas without human activities. Wetlands, as transitional areas between terrestrial and aquatic systems, have received less attention in microplastic pollution research compared to other aquatic ecosystems. This review examines documented research on microplastic occurrence and distribution in different components of wetland systems (excluding constructed wetlands). Based on the results, wetland ecosystems are susceptible to microplastic pollution, with PE/PP as the most common chemical composition and fiber/fragment as the dominant particle shape.
