Are there any international or national guidelines for quality of sediment (in reference of heavy metals) in rivers?
kindly share the information regarding this.
Please Consider the toxicity reference values (TRV) proposed by USEPA (1999), giving for instance:
Cr : 26 (mg/Kg DW); As : 6 (mg/Kg DW); Cd : 0.6 (mg/Kg DW); Pb : 31 (mg/Kg DW)
Regards
Based on the pollution load index (PLI); the pollution load index (PLI) values were above one (>1) indicates advanced decline of the sediment quality.
