16-5 Is the content of pesticides and pesticides metabolites in the ground water still important for medical hydrology / 日本温泉気候物理医学会雑誌

ABSTRACT

Introduction: In the world there are numerous sources to which the population pilgrimage and is convinced of the healing power of incurable diseases. Category of beneficial medicinal waters are waters which include spring and mineral water derived from ground and deepwater. Groundwater is contaminated with substances from agriculture wastewater, for example, pesticides that are toxic substances. Unfortunately was noted down more and more cases of contamination of the deep water. Objectives: Pesticides are employed in agriculture and in public health. Toxicity to humans includes along-term and acute effects. Therefore, knowledge of their concentration in drinking water treatment seems to be very important. The aim of this study was based on the literature indicate the presence of certain pesticides and pesticide metabolites in selected drinking water coming from the ground and deepground. Methods: Literature review. Measurements of pesticide concentrations in the test water samples in publications included in this review were performed by chromatographic techniques. Results: Seven water spring (mountain Vermion-Greece) were studied during the 12-months. Atrazine, diazinon and DEA [deethylatrazine] Their concentrations levels were below 0.060μg/l1). The concentrations of pesticides detected in underground waters were 0.089μg/l for alachlor, 0.098μg/l for atrazine, 0.205μg/l for desethylatrazine, 0.090 μg/l for carbofuran, 0.041μg/l for metolachlor, 0.077μg/l for molinate, 0.018μg/l for propanil, 0.007μg/l for parathion methyl and 0.037μg/l for simazine. Research pesticides atrazine, alachlor, cyanazine in groundwater2) showed the absence of the first two, but altrazine concentration was in the range 0.16-3.7μg/l. In the groundwater below 1.5m concentration was higher than in 3m below. Altrazine was sporadic detected even at a depth of 4.6m, but not below. It has been tested concentration of 10 pesticides in groundwater from Argentina3). Azinphos methyl is the most widely used pesticide. Its concentration was 3.22μg /l. In the groundwater can also identify metabolites of pesticides4). From 150 pesticide metabolites 37 were detected with a concentration <0.025μg/l and median total concentrations of pesticide metabolites was 0.62μg/l. Conclusions: 1. From the selected work indicate that pesticides and metabolites of pesticides pollute water sources, underground water and deepwater. 2. Concentrations of pesticides in most cases are lower than the 0.1μg/l, which is the general limit concentrations of pesticides, and pesticides metabolites in drinking water5), 6). 3. Only in the case of the pesticide azinphos methyl was found elevated concentration of 3.22μg /l, which realises the necessity Identification concentrations of pesticides and their metabolites in mineral and spring waters.
