Abstract

The main objective of the current research is to determine the content of heavy metals from the Bistrita and Siret River banks, respectively Siret River � in Bridge Holt area, Siret River � canal UHE and Siret River- downstream confluence Bistrita/Siret. The choice of sampling points took into consideration the areas where the pollution sources are located. Established maximum values were not exceeded in the case of mercury in the soil for all three sampling points Siret River � in Bridge Holt area, Siret River � canal UHE and Siret River- downstream confluence Bistrita/Siret. Exceeding values recorded in the sampling points Siret River � in Bridge Holt area, Siret River � canal UHE and Siret River- downstream confluence Bistrita/Siret (for cadmium, nickel and chrome) resulted from discharged residual waters, industrial platforms form Bacau city and the improper storage of municipal waste.

Highlights

The main objective of the current research is to determine the content of heavy metals from the Bistrita and Siret River banks, respectively Siret River – in Bridge Holt area, Siret River – canal UHE and Siret River- downstream confluence Bistrita/Siret
The established maximum level for cadmium (0.8 mg/kg d.m.), in the soil was not exceeded in sampling points Siret River – canal UHE and Siret River- downstream confluence Bistrita/Siret
The established maximum level for nickel (35 mg/kg d.m.), in the soil was not exceeded in sampling point Siret River – Bridge Holt

Summary

Introduction

The main objective of the current research is to determine the content of heavy metals from the Bistrita and Siret River banks, respectively Siret River – in Bridge Holt area, Siret River – canal UHE and Siret River- downstream confluence Bistrita/Siret. Exceeding values recorded in the sampling points Siret River – in Bridge Holt area, Siret River – canal UHE and Siret River- downstream confluence Bistrita/Siret (for cadmium, nickel and chrome) resulted from discharged residual waters, industrial platforms form Bacau city and the improper storage of municipal waste. This influence was determined by analyzing the concentrations of heavy metals Siret River – in Bridge Holt area, Siret River – canal UHE and Siret River- downstream confluence Bistrita/Siret, in locations along the Bistrita and Siret River
