Geostatistical estimation of marine microplastics pollution in Hong Kong using benthic fauna as bioindicators.
AI summary Read the abstract
This study reused existing data on microplastics found in barnacles and other bottom-dwelling sea creatures in Hong Kong to map pollution across the region. The highest microplastic levels appeared near the northeast bays and areas close to the Pearl River Delta, suggesting pollution from land sources. Barnacles and gastropods were identified as useful indicators for tracking marine microplastic pollution.
Benthic organisms can act as bioindicators of microplastic pollution in aquatic environments by enabling a time-integrated assessment of the ambient particles suspended in the water column. We employ a geostatistical approach using data of microplastics concentrations found in tissue of the barnacles and benthic fauna collected by Xu et al. (2020a, 2020b) to estimate the spatial extent of marine microplastics pollution in Hong Kong. This paper therefore uses data from two previously published studies and no new samples were collected or new experiments conducted. Regional pollution maps are generated which demonstrate the highest marine microplastics levels occur in the northeast bays and regions adjacent to the Pearl River Delta, indicating terrestrial pollution as a source. We conclude that some classes of benthic fauna and in particular barnacles and gastropods, may provide a pragmatic tool to assist with pollution assessments that are based on contamination levels measured in the environment, which are typically transient.

Researchers examined microplastic occurrence in four barnacle species collected from 30 sites across Hong Kong waters, finding microplastics — predominantly fibers — in all species and proposing barnacles as potential bioindicators of coastal microplastic pollution.
Microplastic Accumulation in Hong Kong’s Marine Sediment: Spatial Pattern and Potential Sources
AI summary Read the abstract
Researchers conducted a comprehensive survey of microplastics in marine sediments across Hong Kong's waters. They found microplastics at every sampling site, with fibers and fragments being the most common forms and polypropylene and polyethylene the dominant plastics. The spatial patterns suggest that coastal urbanization and water circulation are key factors driving where microplastics accumulate in sediments.

Researchers conducted a comprehensive survey of microplastics in marine sediments across Hong Kong, finding uneven distribution with abundance ranging from near zero to high levels in urbanized areas. Source analysis pointed to household waste, fishing activity, and stormwater runoff as primary contributors.
Microplastic pollution in the marine waters and sediments of Hong Kong
AI summary Read the abstract
Seasonal surveys of surface water and sediments across four coastal locations in Hong Kong found microplastics at all sites, with the highest concentrations in the most urbanized harbor areas. This first comprehensive study of Hong Kong coastal waters reveals that even heavily trafficked port environments accumulate large quantities of microplastic pollution.
Spatio-temporal comparison of neustonic microplastic density in Hong Kong waters under the influence of the Pearl River Estuary
AI summary Read the abstract
Spatial and temporal surveys of microplastic density in Hong Kong surface waters found elevated concentrations near the Pearl River Estuary and seasonal variation linked to river discharge. The study provides empirical evidence that river outflow from China's Pearl River is a significant driver of coastal microplastic distribution in Hong Kong waters.
