The investigation aims to determine the
concentration level of heavy metals (HMs) in industrial wastewater
in Chittoor district. The existence contamination of HM causes a
serious problem around the universe due to the several sources,
toxicity, accumulative behavior, and non-biodegradable property of
HMs. The HMs contamination in industrial wastewater around Chittoor
district is prominent. Some parameters such as pH, hardness, and
electrical conductance are used to analyze for each metal. A simple
hot plate digestion procedure was employed using acids (HNO3,
HCl) and developed to determine the concentration of these metals
lead (Pb), iron (Fe), cadmium (Cd), nickel (Ni), and chromium (Cr)
in water by atomic absorption spectrometry technique. This shows
that the presence of Ni, Fe, Cr, Cd, and Pb in the study area has a
significant influence to health. Especially, Cd, Cr, Fe, and Pb
exhibited high significance toxicity effect even at lower
concentration levels of HMs which obtained was usually higher than
the permissible limit for the safe environment as prescribed by the
World Health Organization and Indian standards. The study region
point out the health risk due to wastewater for residents and
aquatic system which shows an ultimate concern for their survival in
the region. |
