A study of Cadmium Concentration, Its Transport and Distribution with Distance in the Jhalana Dungari Area, Jaipur

Abstract

Extensive quarrying activities in the Jhalana Dungari area of
Jaipur are going on for over 25 years. Greenokite mineral (CdS)
present in the area results in high concentration of Cd in the soil
as well as in the water of the area. This paper presents the results
of analysis of soil, rock and water samples for determining concentration
of Cd, its transport and distribution with distance for the
quarrying area. The findings reveal that in water samples the values
are between 0.04-0.10 mg/L, which are considerably higher than
the prescribed limits of  WHO and US standards. Soil samples have
Cd in varying concentration ranging from 0.40-1.50 mg/L. It has
been found that Cd is distributed throughout the hill, but the concentration
is higher around 20 metres from the base.
