Wastewater treatment plant effluents as source of cosmetic polyethylene microbeads to freshwater

Using Ljubljana, Slovenia as a case study, researchers estimated how many polyethylene microbeads from cosmetics pass through a wastewater treatment plant and enter surface waters. The study found that even plants with high removal efficiency still release substantial numbers of microbeads, supporting the case for banning them from personal care products.

Responses of activated sludge under a short-term exposure to facial scrub microbeads: implications from treatment performance and higher-life microbial population dynamics

This study exposed wastewater treatment reactors to microbeads from facial scrub products and found that even short-term exposure disrupted the microbial communities that clean sewage, reducing bacterial counts and treatment performance at higher concentrations. Cosmetic microbeads that pass through drains can therefore impair the biological systems we rely on to treat sewage before it reaches rivers and drinking water sources. The results support policies banning microbeads from personal care products.

Microbeads in exfoliating products: occurrence, abundance, and potential for water contamination in Ho Chi Minh City, Vietnam

Researchers analyzed popular facial and body scrub products sold in Ho Chi Minh City, Vietnam, finding that each gram of product contained 236–942 plastic microbeads ranging in size from 66 to 1,012 micrometers. They estimated that these products release approximately 1.3 billion microbeads annually into local waterways, highlighting personal care products as a significant microplastic source in Southeast Asia.

Clean, but not green: Emission assessment, forecast modelling and policy solutions for plastic microbeads from personal care products in India

Researchers analyzed 45 personal care products sold in India and found that plastic microbeads were present in face washes, scrubs, shower gels, and body scrubs. They estimated current and future microbead emissions based on product usage patterns and population growth, projecting a significant increase in microplastic pollution from these sources. The study calls for regulatory action to ban intentionally added microbeads in personal care products in India.

Microplastic contamination in wastewater: Sources, distribution, detection and remediation through physical and chemical-biological methods

This review covers how microplastics end up in wastewater from sources like textile fibers, personal care microbeads, and broken-down plastic debris, and how they often survive the treatment process. Current removal methods like filtration and chemical degradation are costly and not fully effective. The lack of standardized ways to measure microplastics in wastewater makes it difficult to assess the full scope of human exposure through water systems.

Extraction and Analysis of Microplastic Beads from Personal Care Products

Researchers extracted and characterized polyethylene microbeads from personal care products using hydrogen peroxide/nitric acid digestion followed by FTIR spectroscopy and stereomicroscopy, confirming that three of six facial cleansers tested contained microplastic beads not removed by wastewater treatment, highlighting a direct consumer product pathway to aquatic microplastic pollution.

Physical-chemical characterization of microplastics present in some exfoliating products from Spain

Researchers physically and chemically characterised microplastics from ten personal care exfoliating products marketed in Spain, finding polyethylene microspheres in concentrations between 6-7% of total product weight in some cases. Smaller particles generally appeared at higher concentrations, highlighting these products as a direct source of microplastic pollution entering waterways.

Effectiveness of conventional municipal wastewater treatment plants in microplastics removal: Insights from multiple analytical techniques

Researchers evaluated the effectiveness of conventional municipal wastewater treatment plants in removing microplastics across multiple treatment stages, finding removal efficiencies of 70–90% but documenting that billions of particles still pass through in final effluent daily.

Incidence of microplastics in personal care products: An appreciable part of plastic pollution

A review of 88 studies found that personal care products like exfoliating scrubs release about 1,500 tons of microplastics per year into global waterways through wastewater systems, representing up to 0.8% of all microplastics entering the oceans annually. Polyethylene is the dominant polymer and will persist in the environment long after microbeads are banned.

Microplastics in Cosmetics and Personal Care Products

This review examines the presence of microplastics, commonly known as microbeads, in cosmetics and personal care products and their pathway into aquatic environments through wastewater discharge. Researchers assessed how these tiny particles interact with marine species and other pollutants once they enter water bodies. The study underscores that despite the existence of wastewater treatment plants, microbeads from personal care products remain a persistent source of aquatic plastic pollution.

Microbeads in personal care products sold in Pakistan: extraction, quantification, characterization, and buoyancy analysis

Analysis of twelve personal care products sold in Pakistan — including face washes and scrubs — found plastic microbeads in all of them, ranging from ethylene-vinyl acetate to polyethylene and PET, with most particles sinking in water and therefore likely to settle in aquatic sediments after rinsing. This study underscores the need for stronger regulation of microbead-containing cosmetics in markets where bans have not yet been introduced.

Municipal effluent as a potential source of microplastics in the aquatic environment

This review examined municipal wastewater treatment plants as potential sources of microplastics—including microbeads from personal care products and synthetic fibers from laundry—in aquatic environments. While modern treatment plants remove a significant fraction of microplastics, they may still discharge millions of particles per day and their capacity to remove the smallest particles is limited.

Microplastics removal through water treatment plants: Its feasibility, efficiency, future prospects and enhancement by proper waste management

Researchers reviewed over 80 studies on water treatment plant performance and found microplastic removal ranges widely — from 16% in basic primary treatment up to near 100% with advanced membrane systems — but a major flaw is that removed microplastics concentrate in sludge, which can re-enter the environment. The review recommends optimizing coagulants and sludge treatment to prevent microplastics from simply being relocated rather than eliminated.

Recent advances on microplastics pollution and removal from wastewater systems: A critical review

This review summarizes the latest research on microplastic detection, occurrence, and removal in wastewater treatment plants. While treatment plants can remove 57-99% of microplastics depending on the stage, significant amounts still escape into the environment through treated water and sludge. The findings highlight the need for advanced treatment methods to prevent microplastics from reaching waterways and ultimately human water supplies.
