An Assessment of Heavy Metals Toxicity in Asian Clam, Corbicula fluminea, from Mekong River, Pa Sak River, and Lopburi River, Thailand

Table 1

Mean concentrations of Zn, Cu, Cd, Cr, Mn, and Pb (μg/g ± SD) in freshwater Asian clam.

Metal
Location	Zn	Cu	Cd	Cr	Mn	Pb
Lopburi River	157.73±39.00	88.55±9.75	0.88±0.08	6.95±2.10	13.96±2.55	3.43±2.76
Mekong River	127.33±29.09	84.61±2.95	1.72±0	5.79±1.51	100.63±5.40	3.61±1.50
Pa Sak River	163.65±69.93	127.15±0.91	1.95±0.07	15.0±8.63	95.2±13.29	8.55±9.55

Remark: post hoc: mean metal concentrations of different location sharing a common letter for a particular metal present no significant differences, p>0.05; having different letters represents a significant difference, p<0.05.
