Zinc:Concentration Determination in Soil and Water and Its Transport and Distribution with Distance

Abstract

Greenokite mineral (cds) is present in ferruginous quartzite rocks which are present in Jhalana Dungari area, Jaipur. Zinc is supposed to be associated with cadmium. Zinc occurs together with cadmium generally in the ratio 100:1-1000:1. This paper presents the results of analysis of soil, rock and water samples for determining the concentration of zinc, its transport and distribution with distance
from the quarrying area. The findings reveal that zinc concentration
is not high in water samples and much below the permissible limit
of 5 mg/L. The concentration in soil shows much variation, i.e.,
from 2.4 to 42 mg/L. It is surprising considering the fact that the
rock samples have maximum concentration of 8.8 mg/L. It appears
that the concentration of zinc is high in stones which are removed
by quarrying and used in grinders after crushing. The stone powder
spreads in the nearby area and could increase zinc concentration.
