Fig. 1From: Integrated assessment of biomarker responses and comparative toxicity pathway in snails Bellamya aeruginosa exposed to tributyltin and triphenyltin in sedimentsRelative enzymatic activity (REA) of ethoxyresorufin-O-deethylase (EROD) in the hepatopancreas of Bellamya aeruginosa exposed to sediment-associated tributyltin (a) and triphenyltin (b) of 100, 500, 1000 and 2000 ng/g. Results are mean ± SD. Asterisks indicate significant difference from the control (p < 0.05); double asterisks indicate significant difference from the control (p < 0.01)Back to article page
