ClearEcological risk assessment of aquatic organisms induced by heavy metals in the estuarine waters of the Pearl River
Researchers monitored five heavy metals — arsenic, copper, lead, mercury, and zinc — across eight estuaries of China's Pearl River throughout 2020, finding that copper and zinc posed the greatest ecological risks to aquatic organisms, particularly threatening crustaceans, mollusks, and certain fish species. These findings provide a foundation for setting water quality standards and protecting biodiversity in one of China's most heavily developed coastal regions.

This review compiled copper, lead, and zinc concentrations in aquatic sediments across five ASEAN countries from 1981 to 2021, finding elevated heavy metal levels at sites with high human activity and assessing ecological and health risks from sediment contamination.
An insight into the ecological risks and mitigation of heavy metal pollution in aquatic sediments and marine ecosystems
This review examines heavy metal pollution in aquatic sediments and marine ecosystems, covering contamination sources, ecological risks, and mitigation strategies. The study highlights the deterioration of aquatic zones due to rising pollution from urbanization and industrialization, and discusses how pollutants including microplastics interact with heavy metals to affect biogeochemical cycling and the food chain.

Researchers analyzed the ecological risks of trace metals released from sediments in Chaohu Lake, China, across different seasons and locations. The study found that copper, lead, and zinc posed persistent toxicological risks, with the highest risk occurring in the eastern region during summer months, providing targeted guidance for pollution control and environmental monitoring.
Concentrations and total mass storage of fine sediment, potentially toxic elements (PTEs) and phosphorus in the channel bed of an urban river: a multi-year study
Not a microplastics paper — this multi-year study tracks how fine sediment and toxic elements like lead, arsenic, and zinc accumulate in the bed of an urban river in Canada, finding that concentrations exceed safe thresholds for aquatic life at multiple sites.
Urban stormwater capture for water supply: look out for persistent, mobile and toxic substances
Urban stormwater harvested for water supply was found to contain persistent, mobile, and toxic substances, raising concerns about water quality risks from this increasingly used alternative water source. The study calls for better characterization of stormwater contaminant profiles before use.
The reliability of evaporation ponds as a final basin for industrial effluent: Demonstration of an environmental risk management methodology
Researchers developed a new environmental risk assessment method for industrial evaporation ponds, which are used to store wastewater from power plants and factories. Their analysis found that contaminants in these ponds become more concentrated over time due to evaporation, creating measurable ecological risks that industries need to manage more carefully.
Predicted aquatic exposure effects from a national urban stormwater study
Researchers estimated cumulative acute risks to aquatic ecosystems from contaminant mixtures in episodic stormwater discharges across the US, revealing significant potential exposure effects on multiple trophic levels.
Study on the Accumulation of Heavy Metals in Different Soil-Crop Systems and Ecological Risk Assessment: A Case Study of Jiao River Basin
Researchers assessed heavy metal accumulation in four crops (wheat, corn, potatoes, and leeks) and soils from the Jiao River Basin, evaluating ecological risk from eight heavy metals including copper, lead, cadmium, and arsenic. The study found that cadmium and arsenic posed the highest ecological risks, with crop type influencing heavy metal uptake patterns.
Comparison of leaching behaviour of heavy metals from sediments sampled in sewer systems – environmental and public health aspect
This paper is not about microplastics. It compares heavy metal leaching behavior from sediments collected in different sewer systems, finding that stormwater sewer sediments had higher concentrations of heavy metals, with zinc levels exceeding regulatory limits at some sewer inlets. The study focuses on heavy metal contamination in urban drainage infrastructure rather than microplastic pollution.
Changes in Stormwater Quality and Heavy Metals Content along the Rainfall–Runoff Process in an Urban Catchment
Researchers tracked how stormwater quality changes as rainfall travels through an urban catchment in northeastern Poland, from rooftops to storm drains to a receiving river. They found that heavy metal concentrations and other pollutants varied significantly depending on the collection point and rainfall characteristics. The study highlights how urban surfaces and drainage infrastructure influence the types and levels of contaminants that ultimately reach natural waterways.
Environmental Behaviors, Ecological Risks, and Toxic Mechanisms of Emerging and Legacy Contaminants in China: From Distribution to Management
Researchers reviewed the environmental distribution, ecological risks, and toxic mechanisms of both emerging and legacy contaminants in China's aquatic environments, examining how industrialization and urbanization drive the co-occurrence and combined pollution that threatens ecosystem integrity and human health.
Analysis of Micropollutants in Urban Water Run-off
This study investigates the quality of urban stormwater runoff, focusing on concentrations of micropollutants including heavy metals and microplastics. The research evaluates how runoff from urban surfaces contaminates both groundwater and surface water, and assesses current stormwater management strategies in cities.
Hydrophilic trace organic contaminants in urban stormwater: occurrence, toxicological relevance, and the need to enhance green stormwater infrastructure
Urban stormwater was found to carry a range of hydrophilic trace organic contaminants including pharmaceuticals and pesticides at concentrations with potential toxicological relevance, and current green stormwater infrastructure may not adequately remove them. The findings highlight a need for enhanced stormwater treatment to protect receiving water bodies.
Environmental Quality and Ecological Risk Assessment of Heavy Metals in the Zhuhai Coast, China
Researchers assessed heavy metal distribution and ecological risk in seawater, sediments, and organisms across the Zhuhai coast of China, finding that copper, zinc, and lead exceeded seawater standards and that cadmium and copper posed moderately high ecological risk. Chemical company emissions were identified as the main contributors to the elevated cadmium and copper levels.
Retention of microplastics and tyre wear particles in stormwater ponds
Researchers analyzed stormwater retention ponds to assess their effectiveness at capturing microplastics and tire wear particles from urban runoff. They found microplastics in all water samples and significantly higher concentrations in pond sediments, suggesting that the ponds do retain a portion of these pollutants. The study indicates that while stormwater ponds offer some mitigation, their long-term performance for trapping emerging contaminants like microplastics needs further evaluation.
