Spatial and temporal variations of coastal microplastic pollution in Hong Kong
AI summary Read the abstract
This study documented microplastic contamination in the coastal environment of Hong Kong across multiple sites from 2016 to 2017, finding the highest levels in an industrialized harbor area. Repeated contamination across years confirms that microplastic pollution in Hong Kong's coastal waters is persistent and linked to ongoing urban and industrial activities.
Further to our 2015-16 investigation, this study revealed the repeated presence of microplastics (MPs) in the coastal environment (Deep Bay, Tolo Harbour, Tsing Yi and Victoria Harbour) of Hong Kong from July 2016 to March 2017. The highest level of MPs in coastal surface water (17,182 particles/100 m) was detected in Tsing Yi. Microplastic abundance in sediments of different sites (59 to 225 plastic particles/kg), however, did not vary significantly. MPs in the size of ≤1 mm were predominated in surface waters (53.3% to 98.6%) and sediments (79.1% to 96.8%). MPs in the shape of pellets and fragments were prevalent in surface waters and sediments respectively. Seasonal pattern of microplastic pollution was consistently observed in Victoria Harbour and Tsing Yi, where the number of MPs was always higher in dry season than in wet season for two consecutive years.

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.
Spatial and temporal variabilities of the microplastic pollution in Hong Kong coastline
AI summary Read the abstract
A multi-year study of microplastic contamination in Hong Kong coastal waters identified significant temporal variability linked to seasonal factors, particularly monsoon rainfall and ocean currents from the Pearl River. Microplastic concentrations were highest during and after typhoon season when river discharge and storm runoff peak. The findings suggest that seasonal and meteorological factors must be accounted for when interpreting microplastic monitoring data in coastal Asian cities.
Disentangling the anthropogenic and environmental correlates of microplastic pollution in the coastal waters of a metropolis in Southern China
AI summary Read the abstract
Researchers surveyed 31 sites across Hong Kong's coastal waters and found microplastics at every location, with concentrations ranging widely depending on local conditions. They analyzed both human activity patterns and environmental factors to identify the main drivers of contamination. The study found that population density and proximity to urban discharge points were strongly associated with higher microplastic levels in surface waters.
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.
Hong Kong at the Pearl River Estuary: A hotspot of microplastic pollution
AI summary Read the abstract
Beach surveys around Hong Kong found microplastic densities averaging over 5,500 items per square meter, higher than many other reported coastal areas, with expanded polystyrene dominating. The high contamination reflects Hong Kong's position at the heavily polluted Pearl River Estuary and underscores the regional plastic pollution problem.
