Higher levels of arsenic (As) in drinking water (more than 50 µg/L) seem to cause innumerable health problems across the world. People exposed to high As contaminated water develop acute or chronic health problems depending on the duration of arsenic exposure. Few districts in Assam have been found to have high levels of arsenic in the groundwater. In this present study, the concentration of As in the groundwater of Sundarpara Pt. IV, Santipur village, Dhubri district of Assam, India was analyzed along with biological samples of hair, nail and blood. Of the total water samples analyzed, 58.33% were found above 10 µg/L (but below 50µg/L) and observed visible dermal changes in the inhabitants of Sundarpara Pt. IV. Moderate to severe arsenicosis was observed in the As concentration above 10 µg/L in drinking water from the study area. As concentration in hair samples was found to be above the normal range while it was within the normal range in the case of nail samples. High As concentration was also observed in blood samples. Further, As concentration was found to be higher with the increased in ages and also with the increase in As concentration in groundwater. No sex difference was observed in all the ages groups in the As concentration in hair, nail and blood samples. To avoid the development of arsenicosis, the safe limit of arsenic in drinking water need to be redefined. [ABSTRACT FROM AUTHOR] |
