Abstract Microplastics (MP) are contaminants able to cause adverse effects on organisms. MPs capable interact with other environmental contaminants, including pesticides, altering their toxicity. The objective of the study was research sublethal (enzymatic activity) pesticides alone and in combination MPs. Cholinesterase enzymes used as biomarkers determine evaluate produced organisms after exposure pollutants. This showed acetylcholinesterase (AChE) enzymatic activity tissue Solea senegalensis exposed two pollutants, insecticide chlorpyrifos (CPF) antibacterial triclosan (TCS) without microplastics (MPs). chosen because it is a species high demand its economic value southern Europe, well use this ecotoxicology increasing sentinel species, which justify using assess biological Toxicity tests were performed concentrations between 5 80 μg/L CPF 0.1 0.4 mg/L TCS for 96 h. In addition, each test incorporated that added at different order role possible enhancer caused by previous case CPF, head muscle cholinesterase inhibited from concentration both MPs, AChE treatment approximately half tissues studied. Besides, 0.3 S. . contrast, no significant differences observed + MP compared controls. These results importance studies assessing anticholinesterase combined due abundance these marine environment (biomarker) neurotransmission key physiological processes.
