چکیده انگلیسی
We sampled 17 nesting sites for loggerhead (Caretta caretta) and green turtles (Chelonia mydas) in Cyprus. Microplastics (<5â¯mm) were found at all locations and depths, with particularly high abundance in superficial sand. The top 2â¯cm of sand presented grand meanâ¯Â±â¯SD particle counts of 45,497â¯Â±â¯11,456â¯particlesâ¯mâ3 (range 637-131,939â¯particlesâ¯mâ3). The most polluted beaches were among the worst thus far recorded, presenting levels approaching those previously recorded in Guangdong, South China. Microplastics decreased with increasing sand depth but were present down to turtle nest depths of 60â¯cm (mean 5,325â¯Â±â¯3,663â¯particlesâ¯mâ3. Composition varied among beaches but hard fragments (46.5â¯Â±â¯3.5%) and pre-production nurdles (47.8â¯Â±â¯4.5%) comprised most categorised pieces. Particle drifter analysis hindcast for 365â¯days indicated that most plastic likely originated from the eastern Mediterranean basin. Worsening microplastic abundance could result in anthropogenically altered life history parameters such as hatching success and sex ratios in marine turtles.
