| Abstract | The purpose of this research was to assess the heavy metal contaminations in water used for paddy cultivation in Phitsanulok Province. The total of 60 water samples were randomly collected from groundwater pumped to use in the paddy fields of 30 farmers and irrigation water pumped to use in the paddy fields of 30 farmers. Contaminations of lead, cadmium, copper, zinc, manganese and iron in water samples were analyzed by atomic absorption spectrometer. The results revealed that most of irrigation water used for paddy cultivation contaminated more heavy metal contents than the groundwater. The irrigation water was contaminated with the highest iron content, followed by manganese, zinc, lead, cadmium and copper with average values of 8.606±2.883, 0.662±0.516, 0.351±0.399, 0.097±0.085, 0.050±0.010 and 0.020±0.018 mg/L, respectively, which is considered to be within the Pollution Control Department's standard for agricultural use, but the average cadmium content exceeded the irrigation water standard for agriculture of Office of the Royal Development Projects Board (RDPB) and FAO. The groundwater pumped for paddy cultivation also had the highest iron contamination, followed by manganese, lead, zinc, copper and cadmium, with average values of 2.820±3.468, 0.816±0.932, 0.248±0.190, 0.142±0.239, 0.009±0.024 and 0.001±0.002 mg/L, respectively, which was not higher than the standard of RDPB and the groundwater standards for consumption of the Department of Groundwater Resources and NCAC, except for lead contamination. |
