The study was conducted in the summer season (April-May 2007). The fluoride concentration along with physico-chemical parameters in ground water samples was determined in various villages of Kadi tehsil at Mehsana district of Gujarat state (India), since in most of the villages it is the only source of drinking water. The fluoride concentrations in these villages varied from 0.94 to 2.81 mg/L (1.37+/-0.56) with highest fluoride level at Visalpur (2.08 mg/L) and lowest at Adaraj (0.91 mg/L). There was found a positive correlation of pH with fluoride and a negative relationship of fluoride with bicarbonate which is generally observed in deep ground water.
该研究于夏季（2007年4月至5月）进行。在古吉拉特邦（印度）梅赫萨纳区卡迪乡的各个村庄测定了地下水样本中的氟化物浓度以及理化参数，因为在大多数村庄，地下水是唯一的饮用水源。这些村庄的氟化物浓度在0.94至2.81毫克/升之间（1.37±0.56），维萨尔布尔的氟化物水平最高（2.08毫克/升），阿达拉杰的最低（0.91毫克/升）。研究发现pH值与氟化物呈正相关，氟化物与碳酸氢盐呈负相关，这在深层地下水中普遍存在。
