Nanoplastikoek muskuiluetan eragin ditzaketen kalteak: berezko aldakortasuna eta toxikotasuna bereiztearen erronka

Abstract

The evidence of the harmful effects of microplastics (MPs, ≤ 1 mm) on marine organisms has greatly increased in the last years, but information regarding the impact of nanoplastics (NPs, ≤ 1 μm) is still insufficient. Given the widespread occurrence of polystyrene (PS) MPs and NPs in the marine environment, it is important to determine their potential adverse effects. Mussels are widely used sentinel organisms, among other reasons, because they can internalize particulate pollutants, such as, MPs and NPs, due to their filter-feeding ability. This work aimed to elucidate the differential toxicity of three sizes of PS NPs (50, 200 and 1000 nm) in foodborne exposed mussels’tissues, immune system and at whole organism level.
