Abstract

全国の水道事業を対象に2009~2011年度の原水での農薬の測定計画と検出状況の関連性を水道統計のデータを基に解析した。農薬を測定した水道事業は約650, その約20%で農薬が検出された。農薬を測定した水道事業を水道水源, 農薬の測定回数と測定種類数で分類したとき, 地表水を水源とし農薬の測定回数と測定種類数が多い水道事業のグループは農薬を検出した水道事業の割合 (検出率) や検出された農薬の種類数が多かった。農薬の測定回数が1回のグループは農薬が検出された水道事業の割合は少なく, その多くは1種の農薬を単年度のみで検出していた。地下水を水道水源に使用している水道事業は総じて検出率は低かった。検出された個別農薬は77種, 比較的多くの水道事業 (10以上) で検出されたのは10種程度であった。検出される可能性がある農薬には地域多様性があるが, いくつかは全国の多くの水道事業から検出される可能性が示された。

The relationship between the monitoring plan and the detection of pesticides in raw water at waterworks throughout Japan in fiscal years 2009-2011 was investigated. For analysis, monitoring data of pesticides in the statistics on water supply were used. The number of waterworks at which pesticides monitored were was about 650 and the percentage of waterworks at which pesticides detected were was about 20%. For the waterworks that acquire raw water from surface water, a higher percentage of waterworks detected pesticides in the group of waterworks that frequently monitored many pesticides than in other groups. Additionally, in the group of waterworks that carried out monitoring once a year, a few waterworks detetcted pesticides. Furthermore, most of them detected one pesticide once in the three years. For waterworks that acquire raw water from groundwater, the detection rates of pesticides were low regardless of the monitoring frequency. The number of pesticides detected was 77 among the 102 pesticides listed in the guidelines. However, the pesticieds detected at relatively many waterworks (more than 10) was only about 10. Thus, it was considered that several pesticides might be detected at many waterworks throughout Japan, although many pesticides detected showed regional diversity.
