摘要: Abstract A total of 23 beaches were surveyed between July and September 2019. Meso-litter was collected by sieving sediment from 0.25 m2 quadrats laid along perpendicular transects through 5 mm mesh size sieves. The results showed that plastics the most abundant litter encountered on all beaches. Beaches close to urban areas had a higher number categories (i.e. plastic, metal, foam, paper) compared remote only plastics. In conclusion, lack statistically significant evidence influence proximity centers, predominant activity in beaches, exposure wave action amount meso-litter attest fact marine pollution is geographical spread problem will require national, regional, global approach address. intervention efforts (including beach clean-ups) should preferably target have back vegetation those with seawalls.
