ClearImpact of microalgal biomass and microplastics on the sorption behaviour of pesticides in soil: a comparative study
Researchers examined how microalgal biomass interacts with microplastics to influence pesticide sorption behavior, finding that algal exudates coating MP surfaces altered their affinity for pesticides and affected the overall fate of pesticide-MP complexes in water.
Efficiency of Microalgae Employment in Nutrient Removal (Nitrogen and Phosphorous) from Municipal Wastewater
This review examines how microalgae (tiny aquatic plants) can be used to remove nitrogen and phosphorus pollutants from municipal wastewater. While not directly about microplastics, this research is relevant because effective wastewater treatment is one way to reduce the amount of microplastics that reach waterways and eventually the food chain.
Microalgae–microplastics interactions at environmentally relevant concentrations: Implications toward ecology, bioeconomy, and UN SDGs
This study investigated how microalgae interact with microplastics at environmentally relevant concentrations, examining growth inhibition, aggregation, and photosynthetic effects, with implications for aquatic ecosystem function and the feasibility of microalgae-based bioremediation.
Microplastic interactions with co-existing pollutants in water environments: Synergistic or antagonistic roles on their removal through current remediation technologies
This review examines how microplastics interact with other pollutants like heavy metals, pesticides, and pharmaceuticals in water, often making each contaminant harder to remove during treatment. The interactions between microplastics and co-existing pollutants can produce unpredictable combined toxic effects that are worse than either pollutant alone. Understanding these interactions is important because real-world water contamination involves mixtures, not single pollutants, and current treatment methods may not adequately address these combinations.
Remediation and upcycling of microplastics by algae with wastewater nutrient removal and bioproduction potential
Researchers demonstrated that algae can simultaneously remediate microplastics from water and remove nutrients like nitrogen and phosphorus from wastewater, while also producing valuable biomass, presenting an integrated and sustainable platform that converts plastic waste into a resource.
Interplay of plastic pollution with algae and plants: hidden danger or a blessing?
Researchers tested the ability of three microalgae species to remove microplastics from water through bioadhesion, finding that all three species could adsorb particles onto their surfaces. Removal efficiency depended on particle size, surface charge, and algae cell morphology.
State-of-the-art microalgae-based bioreactor wastewater treatment for the elimination of emerging contaminants: A mechanistic review
Researchers reviewed how bioreactors using microalgae — tiny photosynthetic organisms — can remove a wide range of pollutants from wastewater, including microplastics, heavy metals, and pesticides, through processes like absorption and biological breakdown. While promising, the technology still faces challenges around scaling up and maintaining consistent performance in real-world treatment facilities.
Are native microalgae consortia able to remove microplastics from wastewater effluents?
Researchers investigated whether native microalgae communities found in wastewater could effectively remove microplastics from treatment plant effluent. The study monitored microplastic occurrence across two different types of wastewater treatment plants over one year, characterizing particles by shape, size, and polymer type. Evidence indicates that wastewater-native microalgae consortia show potential as a dual-purpose solution for both microplastic mitigation and biomass production.
Evaluating the impact of innovative algae- based membrane bioreactors against the emerging microplastic crisisin combating water pollution
This study evaluated algae-based membrane bioreactors for removing microplastics and other emerging contaminants from wastewater, finding that combining algal biomass with membrane filtration improved MP removal efficiency compared to conventional biological treatment alone.
Are algae a promising ecofriendly approach to micro/nanoplastic remediation?
This review examines the potential of algae as an eco-friendly approach to removing micro- and nanoplastics from wastewater treatment plant effluents, covering mechanisms including interception, entanglement, and heteroaggregation. Algae also offer the added benefit of nutrient recovery from wastewater and can be further processed into biochar or biofertilizer.
Micro- and nanoplastics interact with conventional pollutants on microalgae: Synthesis through meta-analysis
This meta-analysis of 933 experimental assessments found that micro- and nanoplastics interact with conventional pollutants like heavy metals and pesticides on microalgae in predominantly antagonistic ways, meaning the combined toxicity was often less than expected. This occurs because plastic particles adsorb pollutants from the water, reducing their bioavailability, though the effect varies by plastic size, charge, and aging.
Looking into the effects of co-contamination by micro(nano)plastics in the presence of other pollutants on irrigated edible plants
This review examines the combined effects of micro- and nanoplastics with other pollutants found in treated wastewater used for crop irrigation. Researchers analyzed 19 studies and found that the joint exposure to plastics and contaminants like heavy metals or pesticides often produced different toxicity outcomes than either pollutant alone. The findings suggest that using reclaimed wastewater for irrigation may expose food crops to complex mixtures of pollutants whose combined effects are still poorly understood.

Degradable Microplastics as Vector of Emergent Contaminants in Wastewater: Interactions and Mechanisms of Adsorption
Degradable microplastics in wastewater can act as carriers for pesticides and other contaminants, adsorbing them from the surrounding water and potentially releasing them again in different environmental conditions such as aeration tanks. This 'Trojan horse' behavior is concerning because microplastics may transport pollutants through wastewater treatment systems that were not designed to capture these combined threats.

Microplastics shaped performance, microbial ecology and community assembly in simultaneous nitrification, denitrification and phosphorus removal process
This study found that polystyrene and PVC microplastics disrupted the performance of wastewater treatment systems designed to remove nitrogen and phosphorus, reducing nitrogen removal by up to 10%. The microplastics altered microbial communities, decreased cooperation between beneficial bacteria, and blocked important biological pathways. Since wastewater treatment is a key barrier against pollution reaching drinking water, microplastic interference with these systems could indirectly increase human exposure to harmful contaminants.
