Data for: Data on health risk assessment of nitrate contamination in groundwater of rural areas in the Yerraguntla Mandal, South India

present study was to determine the distribution levels of nitrate contamination in drinking water and its associated health impact limestone mining area Yerraguntla. For this 40 ground water samples were collected randomly during April 2018. Most of the groundwater samples are exceeding the permissible limits of nitrate (45 mg/l). Nitrate concentration in groundwater samples ranges from 2.50 to 760.12, with a mean of 86.13. Hence health risk assessment of nitrate has been carried out. Hazard quotient (HQ) values for infants, children, male and female ranges from 0.05 to 14.25; 0.06 to 18.53; 0.04 to 12.18 and 0.05 to 14.62 respectively. The finding of data showed that HQ value was more than 1 in 42.5 % of samples in groups of infants, children and female, and 35 % of samples in group of male.本研究旨在探明耶拉贡特拉（Yerraguntla）石灰岩矿区饮用水中硝酸盐污染的分布水平及其相关健康影响。为此，研究团队于2018年4月随机采集了40件地下水样本。多数地下水样本的硝酸盐含量超出了45mg/L的容许限值。地下水样本中的硝酸盐浓度范围为2.50至760.12mg/L，平均浓度为86.13mg/L。据此，本研究开展了硝酸盐健康风险评估。婴儿、儿童、男性及女性群体的危险商数（Hazard Quotient, HQ）取值范围分别为0.05~14.25、0.06~18.53、0.04~12.18及0.05~14.62。数据结果表明，婴儿、儿童及女性群体中分别有42.5%的样本其HQ值大于1，男性群体中该比例为35%。
