Enzimas plasmáticas na brânquia de juvenis de Clarias gariepinus expostos a níveis crônicos de alquil benzeno sulfonato linear

Authors :

Linear alkyl benzene Sulphonate (LAS) inhibited all the enzymes in the organ examined except alanine aminotransferase (ALT) and Acid phosphatase (ACP) on exposure of one hundred and fifty C. gariepinus juveniles (mean weight 246.30±14.12g SD/mean length 16.15±1.40cm SD) to chronic levels of 10.00, 20.00, 30.00, 40.00 and 50.00 mg/l for 30 days. Generally, the impact of LAS on the selected enzymes in the gill caused remarkable increase in Aspartate aminotransferase (AST) and significant decrease (P<0.05) in Alkaline phosphatase (ALP), except at 10.00mg/l with increase in detergent concentration when compared to control.
