TO DETERMINE ARSENIC CONCENTRATION (USING ATOMIC ABSORPTION SPECTROSCOPY) IN GROUND WATER FROM KORBA DISTRICT (CG), INDIA

Abstract

Arsenic was discovered by Albertus Magnus in 1250 AD. Arsenic is the 20th most abundant element found on Earth. Arsenic behaves like both a metal and a non-metal because arsenic is a metalloid. The abundance of arsenic in the earth's crust is 1.5 to 2 ppm. Arsenic is the most toxic element found on Earth. Arsenic is found in natural water in the form of arsenite As3+ and arsenate As5+ ions. Whose solubility in water is high. Taking into consideration the harmful effects of arsenic on reaching human body through environment, it causes carcinogenic effects like skin cancer, lung cancer, bladder cancer, liver cancer, prostate cancer, leukemia, non-carcinogenic effects - neurological effects, memory and intellectual function, diabetes, cardiovascular disorder effects, effect on skin, effect on reproductive system, WHO and BIS have determined the concentration of arsenic in drinking water to be 0.1 mg/liter. In 50% of the samples of the study area, the arsenic concentration was more than the concentration determined by BIS and WHO, which varied from 0.18 ±0.007 to 0.88 ± 0.0051, which has proved harmful for the local residents. It can cause serious health risks to the local residents. It is very important to take water treatment measures to protect the local residents from the harmful effects of arsenic. There are many methods of water treatment like electrodialysis, coagulation, reverse osmosis, activated carbon filter, bioabsorbent etc. But water treatment by bioabsorbent is a suitable method at the rural level due to its low cost and easy availability anywhere.
