ClearMethane Production Mechanism and Control Strategies for Sewers: A Critical Review
Not relevant to microplastics — this review covers methane production mechanisms in urban sewer systems and strategies such as oxygen injection and iron dosing to reduce greenhouse gas emissions from wastewater infrastructure.
The Impact of Bisphenol A on the Anaerobic Sulfur Transformation: Promoting Sulfur Flow and Toxic H2S Production
Researchers discovered that bisphenol A, a chemical commonly released from microplastics, promotes the production of toxic hydrogen sulfide gas in anaerobic wastewater environments. At environmentally relevant concentrations, the chemical increased hydrogen sulfide output by 14 to 32% by enhancing the activity of sulfur-cycling microorganisms. The findings suggest that microplastic-derived chemicals could worsen odor and corrosion problems in sewers and wastewater treatment facilities.
The study of the antibacterial efficacy and antioxidative activity mediated by exogenous Hydrogen Sulfide against Aeromonas caviae- an antibiotic-resistant organism
This paper is not relevant to microplastics — it investigates using exogenous hydrogen sulfide gas to reverse antibiotic resistance in a soil bacterium (Aeromonas caviae), with no connection to plastic pollution.
Mapping of microplastics and endotoxins as a potential workplace hazard
Researchers measured microplastic levels and bacterial endotoxins in the indoor air of a facility that converts sewage sludge into fertilizer, identifying potential occupational exposure hazards. Workers in such facilities may inhale significant concentrations of microplastics along with biological contaminants from the sludge, highlighting an overlooked workplace health risk.
The Invisible Threat: Investigating the Effects of Air Pollution on Human Health and the Environment
Not relevant to microplastics — this study investigates how air pollution (particulate matter PM2.5 and nitrogen dioxide) affects human health in Depok, Indonesia, finding links to respiratory and cardiovascular disease.
Exposure of polyethylene microplastics affects sulfur migration and transformation in anaerobic system
This study found that polyethylene microplastics in anaerobic wastewater treatment systems increased the production of hydrogen sulfide, a corrosive and toxic gas, by 15-27%. The microplastics promoted the activity of sulfur-processing bacteria and altered the sulfur cycle within the treatment system. This is relevant because it shows microplastics can disrupt the wastewater treatment processes that protect water quality for downstream communities.
Plastic Smell: A Review of the Hidden Threat of Airborne Micro and Nanoplastics to Human Health and the Environment
This review examines the growing threat of airborne micro- and nanoplastics, which spread globally through atmospheric transport and can settle in both cities and remote areas. Inhaling these particles may cause respiratory inflammation, oxidative stress, and other health problems, and the particles can also carry harmful chemicals and microbes, amplifying their potential impact.
Waste plastic management: Recycling and the environmental health nexus
Researchers reviewed plastic recycling methods and their health and environmental trade-offs, finding that mechanical recycling releases microplastics that can enter the body through inhalation and ingestion, and calling for smarter waste management systems and reduced use of toxic plastic additives.
[Effects of Typical Microplastics on Methanogenesis and Antibiotic Resistance Genes in Anaerobic Digestion of Sludge].
Researchers explored the impacts of polyamide, polyethylene, and polypropylene microplastics on methanogenesis and antibiotic resistance gene dynamics during anaerobic digestion of waste sludge, examining how microplastic contamination affects both biogas production and resistance gene enrichment.
An emerging class of air pollutants: Potential effects of microplastics to respiratory human health?
This review explores the emerging concern that airborne microplastics can be inhaled by humans, potentially causing adverse effects on the respiratory system. Researchers compiled available data on the concentration, size, shape, and chemical composition of microplastic particles found in urban air. The findings suggest that airborne plastic debris represents a largely understudied class of air pollutant with potential implications for human health.
Status of Research on Greenhouse Gas Emissions from Wastewater Collection Systems
This paper is not directly about microplastics — it reviews greenhouse gas emissions from wastewater collection systems and estimates China's annual emissions, without a focus on plastic pollution.
Air Pollution by Beauty Salons of Chapra Town
Not relevant to microplastics — this is a public health study measuring indoor air pollution in beauty salons in Chapra, India, focusing on chemical fumes and particulate matter from haircare and cosmetic treatments as occupational health hazards.
