ABSTRACT: The aim of the present investigation was to research
the relatively heavily polluted area of chromium in water of the Hun River. According to variance analysis, the
concentrations of chromium in water showed significant differences at
different sampling stations. In addition, we obtained the static concentration function of chromium in water by
using a curve-fitting tool and the measured
data. It was clear that the static concentration function perfectly revealed the change in regulations between the concentration of chromium in water and spatial
coordinates. We furthermore determined the relatively heavily polluted area of chromium in water by using a regional
coordinate formula. The results indicated that the relatively heavily polluted
area of chromium in water was from H1 to H2,
which was highly consistent with the measured data. It is clear that the
determination of the relatively heavily polluted area of chromium is helpful to
the comprehensive treatment of chromium pollution. The static concentration
function and the regional coordinate of the relatively heavily polluted area of chromium in water comprehensively describe the distribution characteristics of chromium in water,
which provide a scientific basis for water environment
improvement and risk management in the Hun River.
