| Fish Thunnus albacares were marketed by local fishermen during Febuary to November 2011 from Karachi Fish Harbour. The fishes were collected seasonally spring (February, March), summer (April, May), Monsoon (August), winter (November) for analysis of heavy metals. The highest mean of length (cm) 80.70+ 0.21 and weight (g) 4587.50+ 83.45 was measured in winter season. The highest mean concentration of Fe 46.93+ 13.54 μg/g dry wt. and Mn 5.40+ 3.06 μg/g dry wt. was determined in summer and spring season. The lowest mean of Fe 20.861+ 5.095 µ/g and Mn 4.80+ 1.41 μg/g dry wt. was recorded in spring and summer seasons also. The maximum level of Zn 29.95+ 11.41 μg/g dry wt., Cu 7.08+ 2.64 μg/g dry wt. and Pb 0.54+ 0.13 μg/g dry wt., was measured in winter season. The lowest mean of Cd 0.15+ 0.11 μg/g dry wt. was determined in spring season. The concentration of metals in fish muscles as follows: Fe> Zn> Cu> Mn> Pb> Cd. |
