A questionnaire study and field visit showed that diazinon and malathion were the most commonly used pesticides in Qazvin province, Iran. Concentrations of these pesticides were determined in water sources; include springs, wells and Shahrood River. Springs water samples had the best water quality; but deep wells were the most polluted water samples. Diazinon was detected in 46.6 % of the samples, while malathion occurrences frequency was in 13.3 % of the samples. Diazinon and malathion were detected in maximum concentration of 19.44 and 18.12 μg L(-1), respectively. The obtained results showed that diazinon was detected in higher than life-time health advisories in wells and in Shahrood River samples; so, it can bring up threats to human health. Interpolation of diazinon and malathion in water sources showed that diazinon had the most widely scattering condition in deep wells. Also, cross validation with the root mean square error (RMSE) indicated that the natural neighbor interpolation of malathion has the minimum RMSE.
一项问卷调查和实地考察显示，在伊朗的卡兹温省，二嗪磷和马拉硫磷是最常用的农药。这些农药的浓度在水源中进行了测定，包括泉水、水井和沙赫鲁德河。泉水样本的水质最好，但深水井是污染最严重的水样。在 46.6%的样本中检测到了二嗪磷，而马拉硫磷的出现频率为 13.3%。在水样中，二嗪磷和马拉硫磷的最高浓度分别为 19.44 和 18.12μg/L。结果表明，在水井和沙赫鲁德河样本中，二嗪磷的浓度超过了终生健康建议值，因此可能对人类健康构成威胁。对水源中二嗪磷和马拉硫磷的插值结果表明，二嗪磷在深水井中的分布最为广泛。此外，与均方根误差 (RMSE) 的交叉验证表明，马拉硫磷的自然邻域插值具有最小的 RMSE。
