ClearIntegrated Ecological Risk Assessment of the Agricultural Area under a High Anthropopressure Based on Chemical, Ecotoxicological and Ecological Indicators
Researchers conducted an integrated ecological risk assessment of agricultural land using chemical, ecotoxicological, and ecological indicators, finding that while chemical analysis overestimated risk, the combined approach revealed most of the area had acceptable risk levels despite over a century of anthropogenic pressure.
Combined risk assessment of organic pollutants (PCBs and OPEs) accumulation in Rice (Oryza sativa L.)
Researchers conducted combined risk assessments of polychlorinated biphenyls (PCBs) and organophosphate esters (OPEs) accumulation in rice (Oryza sativa) using hydroponic experiments, finding that combined organic pollutant exposure had greater effects on plant growth and tolerance mechanisms than individual contaminants alone. The study reveals synergistic toxicological interactions between these co-occurring pollutants in food crop systems.
Deciphering Pesticide Stress Responses in Rice Through Integrated Multi-Omic Assessment
This review synthesizes research on how pesticide exposure affects rice plants at the molecular level, drawing on transcriptomic, proteomic, and metabolomic studies. Researchers found that pesticides trigger detoxification enzymes, alter antioxidant defenses, and reprogram metabolic pathways in rice. The study highlights how integrating multiple omics approaches can provide a more complete picture of pesticide stress responses in crops.
An alternative approach to risk rank chemicals on the threat they pose to the aquatic environment
This paper proposed an alternative approach for ranking chemicals by the threat they pose to aquatic ecosystems, integrating exposure and hazard data in a more ecologically meaningful way than standard risk quotient methods.
Avaliação Da Toxicidade Do Solo Com Ensaios Ecotoxicológicos Em Diferentes Áreas De Cultivo De Tomate
Researchers evaluated soil toxicity in tomato cultivation areas under conventional, ecological transition, and organic farming conditions using ecotoxicological bioassays with earthworms (Eisenia fetida), testing acute, chronic, and avoidance responses to assess differences in substrate toxicity across the three management practices.
A Comparison of Rice Root Microbial Dynamics in Organic and Conventional Paddy Fields
Researchers compared the root-associated microbial communities of rice plants grown in organic versus conventional paddy fields across different growth stages. They found that organic farming supported more dynamic and diverse microbial communities, including beneficial methane-oxidizing and nitrogen-fixing bacteria at key growth stages. The study suggests that agricultural management practices significantly shape the microbial partners that support rice plant health and nutrient uptake throughout the growing season.
A Spatially‐Resolved Framework Reveals Contrasting Root and Leaf Strategies to Nanoplastic‐Arsenic Stress in Rice
This study used a new statistical framework to show that rice roots and leaves respond very differently when exposed to both nanoplastics and arsenic simultaneously: roots mount a straightforward additive defense, while leaves show complex antagonistic molecular interactions centred on iron storage. The finding is important for food safety because it reveals that standard toxicity tests on individual stressors may underestimate the risks posed by contaminant mixtures in food crops.
Cocktails of pesticide residues in conventional and organic farming systems in Europe – Legacy of the past and turning point for the future
A multi-country survey of EU agricultural topsoil found widespread pesticide residue cocktails at conventional and organic farms, with conventional sites carrying significantly higher residue loads and the results highlighting long-term legacy contamination across European soils.
Microplastics meet invasive plants: Unraveling the ecological hazards to agroecosystems
This study examined how microplastic contamination in soil combines with invasive plant species to affect rice crops. The combination of both stressors caused greater changes in rice metabolism and antioxidant responses than either stressor alone. These findings highlight how microplastic pollution in agricultural soil can interact with other environmental challenges to threaten food safety and crop health.
Chemical Mixtures and Multiple Stressors: Same but Different?
This review highlights the parallels between chemical mixture research and multiple stressor ecology, arguing that both fields face similar challenges in predicting joint effects and would benefit from integrated frameworks combining chemical and non-chemical stressor assessments.
Impact of Pesticide Toxicity in Aquatic Environment
This review examines the toxic effects of pesticides on aquatic environments, focusing on how agricultural runoff introduces harmful chemicals into waterways. Researchers found that pesticide contamination affects fish, invertebrates, and aquatic plants through bioaccumulation and disruption of biological processes. The study emphasizes the need for more sustainable agricultural practices and improved water quality monitoring to protect aquatic ecosystems from pesticide pollution.
Assessing the chemical interactions and biological effects of a petrochemical and bio-based plastic with a common plastic flame retardant and solvent
Researchers assessed the combined chemical interactions and biological effects when organisms were exposed to both petrochemical and agricultural contaminants simultaneously. Mixture effects were often greater than predicted by individual chemical toxicity, highlighting the importance of studying realistic multi-contaminant exposures.
Advances in the Agro-Environment Migration of Organic Chemical Pollutants and Their Biotransformation in Crops
This review examined the migration and biotransformation of organic chemical pollutants across agricultural environments including soil, water, and crops, covering how agrochemicals, pharmaceuticals, and industrial chemicals enter food chains. The authors synthesize mechanisms of pollutant uptake by crops and identify key research gaps for protecting food safety.
Complex Mixtures and Multiple Stressors: Evaluating Combined Chemical Exposures and Cumulative Toxicity
This review examined how complex chemical mixtures and multiple stressors interact to produce cumulative toxicity, highlighting that traditional single-chemical risk assessments underestimate real-world exposure risks where organisms face simultaneous pollutant combinations.
Integrated Physiological, Transcriptomic and Metabolomic Analyses of the Response of Rice to Aniline Toxicity
Researchers used physiological, transcriptomic, and metabolomic analyses to study how rice plants respond to aniline, a chemical pollutant derived from plastics and industrial processes. They found that low concentrations slightly promoted growth, but higher levels significantly inhibited rice development and activated stress response pathways. The study provides molecular-level insights into how this common industrial contaminant affects crop plants.
Toxicological Interaction Effects of Herbicides and the Environmental Pollutants on Aquatic Organisms
This review examines the toxicological interaction effects of herbicides in combination with other environmental contaminants on aquatic organisms, particularly fish, noting that herbicides in water bodies rarely occur in isolation and may interact synergistically or antagonistically with co-occurring xenobiotics. The authors synthesize evidence on how herbicide-pollutant mixtures affect fish physiology in ways that differ from single-compound exposures.
Field validated biomarker (ValidBIO) based assessment of impacts of various pollutants in water
This review examines field-validated biomarker approaches for monitoring water pollution, showing that enzymatic activity changes in fish exposed to heavy metals, pesticides, microplastics, and persistent organic pollutants serve as sensitive and reliable indicators of aquatic contamination across diverse environments.
Advances in aquatic toxicology for predicting effects of multiple pollutants on aquatic organisms
This review examines advances in aquatic toxicology for predicting how mixtures of contaminants — heavy metals, pesticides, pharmaceuticals, and microplastics — interact in aquatic organisms, highlighting computational modeling and mixture toxicity approaches as key tools for environmental risk assessment.
Characterizing Freshwater Ecotoxicity of More Than 9000 Chemicals by Combining Different Levels of Available Measured Test Data with In Silico Predictions
Researchers developed a method combining laboratory toxicity data with computer predictions to estimate the ecological hazards of over 9,000 chemicals in freshwater environments.
