The average contamination level was 132.5 items per liter, with fibers being the most prevalent shape at 62%, and polymer analysis identified ABS, EVA, polyamide, and PET, providing baseline contamination data for this coastal area.
Plastic waste occurrence on a beach off southwestern Luzon, Philippines
Researchers documented plastic waste on a beach in southwestern Luzon, Philippines, finding high levels of macroplastic litter and establishing baseline microplastic contamination data for a country identified as one of the largest contributors of plastic waste to the ocean.
Accumulation of cadmium and lead in macroinvertebrates in relation to sediment concentration and the dynamics of environmental parameters in a tropical estuary of the Colombian Pacific
This paper is not relevant to microplastics research — it investigates the accumulation of cadmium and lead heavy metals in macroinvertebrates from a tropical Colombian estuary, focusing on metal pollution rather than microplastic contamination.
Abundance And Distribution Of Plastic Debris In Beach Sediment And Seawater Of The Northern Straits Of Malacca
Researchers surveyed the abundance and distribution of macro-, meso-, and microplastic debris in beach sediments and seawater along the Northern Straits of Malacca in Malaysia, providing baseline contamination data relevant to the country's national roadmap toward reducing single-use plastics.
Assessment of microplastics and heavy metal contamination in surficial sediments of Pasig River, Philippines during wet season
Scientists measured microplastic and heavy metal contamination in river sediments of the Pasig River in the Philippines, finding between 2,700 and 28,250 plastic particles per kilogram. Contamination was highest in urbanized areas, with polyester and polyethylene being the most common plastic types found. Since this river serves as a water source for nearby communities, the findings raise concerns about human exposure through contaminated water.
