邻苯二酚环境标准和分析标准研究

苯胺泄漏对水体的污染应急测定项目应选择苯胺和邻苯二酚。邻苯二酚是苯胺降解的中间产物，邻苯二酚同样具有较大毒性。挥发酚的测定不能准确反应水中所含的邻苯二酚，水和废水监测分析方法（第四版）没有邻苯二酚的监测分析方法，已经不能满足苯胺泄漏对饮用水源地污染的应急监测需要。文章综述了邻苯二酚的主要测量方法。参照前苏联渔业水体中有害物质邻苯二酚的最高容许浓度标准，比较了近年来测定水中邻苯二酚不同方法的检出限，基于邻苯二酚的毒性考虑和具备霹F苯二酚的多种测量方法，建议建立邻苯二酚相应的环境标准和标准方法。

Studies on Environmental Standards and Analytical Standards of Catechol

Aniline and catechol should be selected as agents for aniline spill on water pollution emergency response test. Cat echol is an intermediate product of aniline degradation which has high toxicity. Determination of volatile phenols contained in the water can not accurately reflect the catechol. Water and Wastewater Monitoring and Analysis Methods （fourth edition） does not in elude catechol monitoring and analysis methods, which is insufficient to meet the needs for aniline spill on the emergency source of drinking water contamination monitoring. This paper reviews the main methods of catechol measurement. With reference to maximum allowable concentration of eatechol of former Soviet Union fisheries Harmful Substances in Water and recent cateehol de tection limits, this study proposed the establishment of catechol appropriate environmental standards and standard methods based on the toxicity of catechol with catechol considerations and a variety of measurement methods.
