Summary: The study assessed the levels of polycyclic aromatic hydrocarbons (PAHs) in sediments collected from the mouth of the Balsas River, Pacific Coast, Mexico. The PAH levels varied depending on the season and indicated anthropogenic activities in the region. The analysis of different ratios revealed a mixed source of PAHs from petroleum and biomass combustion. The evaluation also showed moderate pollution with adverse biological impacts and high levels of mutagenic and carcinogenic PAH compounds in the region.

Summary: Azoxystrobin is a widely used systemic fungicide that inhibits mitochondrial respiration in target fungi, but its effects on non-target organisms are not well studied. This research evaluated biomarkers of oxidative stress, hematological, physiological, and genotoxicity in cichlid fish exposed to environmentally relevant concentrations of AZX, showing negative effects at realistic concentrations and highlighting the importance of considering developmental stage on biomarker evaluation.

Summary: Azoxystrobin, a widely used fungicide, was found to exhibit higher toxicity in natural soil compared to artificial soil when assessing its ecological risk on earthworm populations. The traditional artificial soil testing method may underestimate the ecotoxicity of azoxystrobin in a real agricultural environment.

Summary: This study aimed to assess the neurotoxic effects of acute BPA exposure at environmentally relevant concentrations in adult zebrafish. Results showed that exposure to 1500 ng/L of BPA reduced swimming distance and increased freezing time. Biomarker evaluation revealed the production of reactive oxygen species and increased acetylcholinesterase activity in the zebrafish brain. Gene expression analysis also indicated overexpression of mbp, alpha 1-tubulin, and manf. Based on these findings, it can be concluded that environmentally relevant concentrations of BPA can cause anxiety-like behavior and neurotoxic effects in adult zebrafish.

Summary: Pesticides can cause oxidative stress and damage to the biotransformation system in fish and other organisms. Ethoxyresorufin-O-deethylase (EROD), glutathione S-transferase (GST), catalase (CAT), superoxide dismutase (SOD) activities, and levels of reduced glutathione (GSH) are biomarkers that indicate the interaction between toxicants and drug-metabolizing and antioxidant systems. The study found that pesticides increase EROD activity regardless of the life stage of fish. In exposed juveniles, CAT and GST variability decreased and increased, respectively. CAT activity was higher in females, while EROD and GST activities increased in males after pesticide exposure. Organophosphorus (OPs) and organochlorine insecticides, along with imidazole and triazole fungicides, had the largest impact on the biomarkers.

Summary: This study investigated the effects of low level MCZ exposure on mouse ovaries. The results showed that MCZ exposure led to damaged ovarian structure and increased apoptosis in mice, which may be achieved by affecting the function of mitochondrial respiratory chain and inducing oxidative stress.

Summary: The experiment showed that leaching of 1,2,4-triazole from barley seeds coated with triazole fungicides is a possibility, but only a small percentage of the fungicides ended up as 1,2,4-triazole in the leachate. Therefore, when evaluating the leaching risks from pesticide applications in agriculture, both seed dressing pesticides and their degradation products should be taken into consideration.

Summary: This study investigated the effects of diazinon on fish and explored the potential protective effects of silymarin supplementation. Diazinon exposure caused liver damage in fish, but silymarin showed potential in reducing oxidative stress and restoring enzyme activities. However, the effectiveness of silymarin on creatine phosphokinase, glutathione reductase, and ammonia may be limited.

Summary: Skin lesions caused by UV radiation seriously affect people's life quality. The natural composite gel derived from fish scales (SE-gel) has been found to effectively protect and repair UV-irradiated skin by inhibiting oxidative stress and inflammatory responses. SE-gel demonstrated good UV absorption, water absorption, moisturizing, and free radical scavenging abilities. In vitro and in vivo experiments showed that SE-gel could improve cell viability, reduce oxidative stress, and prevent UV-induced skin damage and inflammation, suggesting its potential application in UV-irradiated skin damage prevention and repair.

Summary: The study on the water quality of Zayandeh Rood river in central Iran revealed the presence of various pharmaceutical active compounds and hormone-like compounds, with higher concentrations detected in treated wastewater. Despite the presence of these compounds in surface water and drinking water, the overall human health risk is considered minor according to the relevant effect-based trigger values.

Summary: Soil pollution from emerging contaminants poses a significant threat to water resources management and food production. A multi scale biophysical model has been developed to predict the fate of ionizable compound in the soil-plant continuum, using a Bayesian probabilistic framework for calibration and evaluation, showing satisfactory fitting performance and limited predictive uncertainty. pH conditions in both soil and xylem play a crucial role in the uptake and translocation of ionizable compounds, according to the model results.

Summary: This study investigated the effects of pollution on the metabolic profiles and oxidative stress biomarkers in fish. The results showed that fish responded with an antioxidant response and absorbed pollutants into their metabolism within seven days. The metabolic profiles in fish liver changed rapidly in the short term, but to a lesser extent in the long term. Fish transferred from polluted water to reference water eliminated pollutants within 14 days, but some elevated metabolic compounds persisted for at least two months.

Summary: The sorption of organic contaminants in soils and sediment plays a vital role in their mobility in the vadose zone environment. This study evaluated Freundlich sorption isotherms for eleven micropollutants and correlated the sorption coefficients with soil properties to predict sorption behavior. Predicted distribution maps were then used to assess groundwater vulnerability. The results showed different sorption patterns among the compounds, emphasizing the importance of considering soil properties in understanding and managing contaminant mobility.

Summary: An upscaled passive sampler variant based on diffusive gradients in thin films for polar organic compounds was tested in several field studies. The performance of the sampler was evaluated in the treated effluent of a municipal wastewater treatment plant and in the raw municipal wastewater influent. The sampler showed robustness and repeatability, but deteriorated after exposures longer than 14 days.

Summary: The accumulation and distribution of different pharmaceuticals in onion, spinach, and radish plants grown in six soil types were investigated. Neutral molecules showed higher accumulation and translocation to plant leaves compared to ionic molecules. The accumulation of carbamazepine (CAR) and its metabolite in plant leaves indicated the potential risk of pharmaceutical entrance into the food chain.
