東日本大震災による被災地の環境・衛生の確保への取組

摘要

宮城県では，環境省等の支援を受けながら，東日本大震災の津波被災地において，アスベストのほか，ダイオキシン類や重金属類等の有害大気汚染物質，窒素酸化物や浮遊粒子状物質等について大気環境モニタリングを定期的に実施した．その結果，環境基準や指針値が設定されている項目については環境基準等を満足し，アスベストのように環境基準等が設定されていない項目については，通常の一般大気環境とほぼ変わらない値であった．アスベスト対策としては，大気環境モニタリングのほか，がれきの散乱場所のパトロールや被災建築物の解体工事現場の立入検査の強化　関係団体等に対する飛散防止対策徹底の要請等も行い．飛散防止対策の徹底や災害廃棄物の適正処理を促進した．水産加工場から流出した魚介類等の腐敗による悪臭および衛生害虫の発生への対策については，市町からの要望に応じて自衛隊による駆除作業を調整するとともに．衛生講習会を開催するなど，市町を支援した．%Miyagi prefecture conducted the atmospheric environmental monitoring survey periodically in the areas affected by the Great East Japan Earthquake and tsunami, measuring asbestos, nitrogen oxide (NOx), suspended particulate matter and hazardous air pollutants such as dioxins and heavy metals under support of Ministry of Environment and other organizations.rnThe survey results showed that the collected samples conformed to environmental standard and the concentration of the substances which have not environmental standards like asbestos showed nearly equivalent to normal atmospheric environment.rnTo prevent scattering of asbestos, we not only conducted atmospheric environmental monitoring but also strengthened patrols debris scattered areas and on-the-spot inspections at demolition work site. Furthermore, we requested related organizations to take preventive measures thoroughly. Through those efforts, we promoted prevention of scattering of asbestos and proper disposal of disaster waste. As for the countermeasure against offensive odors and outbreak of sanitary insects caused by rotten fish flowed out from marine product processing factories, we coordinated pest control operation conducted by the Japan Self Defense Forces in compliance with requests of municipalities and held sanitation workshops.
