Abstract:
Objective To analyze the status of Huangshui River water pllution by chromium(Cr6+)and define the pollution source. Methods Water samples were collected from 5 monitoring points closely located at the bank of Huangshui River from the upper reaches to the lower reaches including A spring,Huanghai canal,Duoba water source well,Zhamalong,Xigangqiao,and also from the location of the upper reaches of Halejian River in the area of source of Huangshui River established as the control monitoring point during 1996-2003. The contents of Cr6+ in the water samples from above sampling points were determined. Results During 1999-2003,the average content of Cr6+ in the water samples from A spring was 45.192 mg/L,and those from Huanghai canal in the upper reaches of Huangshui River Zhamalong and Xigangqiao increased year by year gradually.By the end of 2003,Cr6+ hadn't been found in the water samples from the upper reaches of Halejian River,but Cr6+ had been found first in the water samples from Duoba water source well with a concentration of 0.007 mg/L. Conclusion Haibei Chemical Industrial Works near A spring was the main source for the Cr6+-pollution of water body of the upper reaches of Huangshui River.
