(Ecological Society of India, 2017) Chandana Suman; Sandeep Kumar Tripathf; Priyankar Raha
The present study has been carried out to determine the occurrence, prevalence and contributing factors to the incidence of goitre in .tarsi region Gonda district, Uttar Pradesh. To achieve these objectives, cultivated soil and ground water samples were collected from thirty five reference locations, In order to determine their physico-chemical properties of soil, ionic concentrations of ground water, iodine and selenium concentrations in both the soil and water samples. The soil mean value of hot water extractable iodine and selenium was estimated as 3.33 and 0.109 mg kg-1, with range of 1.81-4.46 and 0.012-0.287 mg kg-1, respectively. The iodine and selenium concentration In ground water varied from 1.21-26.71 and 12.39 to 63.36 μgL-1 with mean of 15.52 and 35.26 μgL-1, respectively. The pH, EC. Cr, SO/, NO;, PO Ca2+ Mg2+, Na+, K+. and NH/ of ground water were within the desirable limit of WHO for drinking purpose, except HCO,∗ and CO∗ Ions concentration. Higher concentrations of HCO3- and CO32- In ground water enhanced the pH of the water. In view of the quality of ground water, the water under study was good quality for drinking purpose, as most of the pH was within the range of 6.5 to 9.2 and EC was also below 2 dSm"1. © 2017 Ecological Society of India.
