Abstract
This study assesses the distribution of heavy metals—Zinc (Zn),
Chromium (Cr), Manganese (Mn), and Copper (Cu)—in wastewater from four
wastewater bodies in Sardarshahar, a semi-arid city in the state of Rajasthan,
across pre-monsoon, monsoon, and post-monsoon seasons. Results show Zn, Cr, and
Mn are consistently present. Zn and Cr showed significant seasonal and spatial
variations, whereas Mn showed significant temporal variation only. Cu was
detected only once during the monsoon at a single site. Notably, chromium
concentrations exceeded the permissible limits set by the Central Pollution
Control Board (CPCB), indicating potential environmental and public health
risks. Lead (Pb), Mercury (Hg), and Cadmium (Cd) were absent in all samples,
which suggests limited inputs of these toxic metals. The findings emphasise the
need for targeted wastewater management and continuous monitoring to mitigate
heavy metal contamination in semi-arid wastewater bodies.
