ClearA global meta-analysis of phthalate esters in drinking water sources and associated health risks
This meta-analysis examined phthalate levels — chemicals that leach from plastics — in drinking water sources around the world. Several phthalates exceeded safe limits in certain regions, posing potential health risks including hormone disruption and cancer, especially with long-term exposure.
Microplastics as an emerging menace to environment: Insights into their uptake, prevalence, fate, and sustainable solutions
This review provides a comprehensive look at how microplastics enter the environment, accumulate in living organisms, and move through food chains. The paper covers sources, transport mechanisms, and the health implications of microplastic exposure for both wildlife and humans. The authors also discuss emerging solutions including biodegradable alternatives and advanced filtration technologies.
Degradation and ecotoxicity of favipiravir and oseltamivir in the presence of microplastics during ozonation and catalytic ozonation of synthetic municipal wastewater effluents
Researchers tested whether ozone-based water treatment could effectively remove antiviral drugs from wastewater, both with and without microplastics present. They found that ozonation removed up to 84% of favipiravir and 64% of oseltamivir, but the presence of microplastics reduced degradation rates by 30-40%. The study suggests that microplastics in wastewater may interfere with advanced treatment processes, making it harder to fully eliminate pharmaceutical contaminants.
Combined effects of polyethylene terephthalate and abamectin on enzymatic activity and histopathology response in juvenile zebrafish (Danio rerio)
Researchers studied the combined effects of PET microplastic fragments and the pesticide abamectin on juvenile zebrafish over 96 hours. They found that microplastics increased the bioavailability and toxicity of the pesticide by inhibiting protective enzymes in the fish, and the combination caused tissue damage in the liver and kidney. The study highlights that microplastics can act as carriers for other environmental contaminants, amplifying their harmful effects on aquatic life.
Management of Emerging Pollutants with a Circular Economy Approach: Lessons from Developed Countries and a Case Study in Northern Cyprus
Researchers reviewed how developed countries manage emerging pollutants through circular economy frameworks and applied those lessons to a case study in Northern Cyprus. The study assessed policies for handling contaminants including microplastics, pharmaceuticals, and industrial chemicals. The findings suggest that circular economy approaches can be adapted for developing regions to more effectively manage emerging pollutant threats.
The predictive model for COVID-19 pandemic plastic pollution by using deep learning method
Researchers built a deep learning model to predict how pandemic-related plastic waste — masks, gloves, and sanitizer bottles — would spread as pollution across Iranian megacities during COVID-19. Their neural network outperformed six other modeling methods, offering a tool for governments to manage hazardous plastic waste during future health crises.
Functionalization of polymers and nanomaterials for water treatment, food packaging, textile and biomedical applications: a review
This review covers surface functionalization strategies for polymers and nanomaterials to improve adhesion, wettability, biocompatibility, and performance in water treatment, food packaging, and biomedical applications. Functionalization is highlighted as an approach to expand the utility of inert conventional polymers and nanomaterials without the environmental drawbacks of additive-laden plastic products.
Monitoring of Rivers and Streams Conditions Using Biological Indices with Emphasis on Algae: A Comprehensive Descriptive Review toward River Management
This comprehensive review examines algal communities as biological indicators of river and stream health, covering how algal indices respond to changes in nutrient levels, salinity, flow regime, and other environmental variables relevant to river management and ecological assessment.
Improvement of photocatalytic ammonia production of cobalt ferrite nanoparticles utilizing microporous ZSM-5 type ferrisilicate zeolite
This study developed cobalt ferrite nanoparticles as photocatalysts for ammonia production as a sustainable alternative to the energy-intensive Haber-Bosch process. The approach aimed to advance nitrogen fixation technology using light-driven reactions with materials that can be synthesized without fossil fuel inputs.
Experimental Investigation and CFD Simulation of Cryogenic Condenser
This paper is not about microplastics; it presents experimental and CFD simulation results for a cryogenic condenser used in oxygen liquefaction systems.
Landslide Mapping Using Two Main Deep-Learning Convolution Neural Network Streams Combined by the Dempster–Shafer Model
Researchers evaluated deep-learning convolutional neural network approaches combined using the Dempster-Shafer model for mapping earthquake-induced landslides from PlanetScope optical and ALOS topographic data, finding that fusing two CNN streams improved mapping accuracy over single-stream approaches for post-earthquake landslide inventory generation.
G-C3N4 Dots Decorated with Hetaerolite: Visible-Light Photocatalyst for Degradation of Organic Contaminants
Researchers developed a graphitic carbon nitride and hetaerolite composite photocatalyst that degrades organic contaminants under visible light, offering a cost-effective approach to removing emerging pollutants from water using solar energy.
Determination of nano and microplastic particles in hypersaline lakes by multiple methods
Researchers used multiple analytical methods to detect and characterize nano- and microplastic particles in a large hypersaline lake, finding both types present across different seasons and locations. The unique chemistry of hypersaline environments affects how plastic particles behave and accumulate. This is one of the first studies to examine microplastic contamination in hypersaline lake systems, which are ecologically distinct and understudied.
Discharge coefficients for ogee spillways
Researchers fabricated physical models of ogee weirs with varying upstream slope angles (vertical, 18, 33, and 45 degrees), apron thicknesses, and downstream submergence conditions to investigate factors affecting discharge coefficients, finding that the coefficient increases with the ratio of spillway height to head (P/He) before plateauing and decreases under submerged-flow conditions.
Constructed wetlands as treatment systems: An overview and bibliometric analysis
This bibliometric review analyzed the scientific literature on constructed wetlands as water treatment systems from the field's origins through 2021, identifying major research themes and trends. Constructed wetlands are relevant to microplastic management as they can trap and remove plastic particles from wastewater effluents.
