Assessment of Ecological Risk of Heavy Metals Using Probabilistic Risk Assessment Model (AQUARISK) in Surface Sediments from Wami Estuary, Tanzania

Table 4

Pearson’s correlation coefficients between heavy metals are sediments.

	As	Cd	Cr	Cu	Pb	Zn
As	1.00
Cd	-0.05	1.00
Cr	-0.42	0.16	1.00
Cu	0.46	0.19	-0.24	1.00
Pb	0.07	0.18	0.07	0.26	1.00
Zn	-0.46	0.14	0.65	-0.04	0.32	1.00

Correlation is significant at the 0.05 level (2-tailed).
