title: Total mercury in liver and muscle tissue of two coastal sharks from the northwest of Mexico.
abstract: Total mercury (THg) in liver and muscle of three costal sharks from Mexico were evaluated. The highest concentrations of THg in muscle tissue of juveniles were found in Sphyrna lewini (0.82 ± 0.33 mg kg(-1) wet basis). Rhizoprionodon longurio adults had the highest concentrations (0.92 ± 1.03 mg kg(-1)). THg concentrations in liver were low compared to those found in muscle tissue; higher levels were found in liver of juvenile S. lewini (0.250 ± 0.07 mg kg(-1)). Results showed that 35 % of muscle tissue samples are above the precautionary limit (0.50 mg kg(-1) of THg) and a 7 % exceeded the maximum limit for human consumption (1 mg kg(-1)).
