浙江省地方环境标准制定思考

地方环境标准是对国家环境标准的补充和完善。为加大污染控制力度,适应新形势下环境管理和执法要求,有效改善和保护环境质量,针对浙江省主要环境问题和现行国家环境标准的不足,结合产业发展方向和环境保护目标,制定浙江省地方环境标准十分必要。主要从浓度控制与排放总量控制相结合、敏感或特殊有毒有害污染物控制、行业污染控制和相关环境质量等方面提出了地方环境标准的制定思路。     

结合《土壤污染防治行动计划》探讨中国土壤环境监管制度与标准值体系建设

2016年,中国国务院印发《土壤污染防治行动计划》(简称《土十条》),明确提出对农用地土壤实施分类管理,按照污染程度划分为优先保护类、安全利用类和严格管控类;对建设用地要防范新增污染,针对疑似污染地块,开展土壤环境状况调查评估,保障地块安全再利用;以影响农产品质量和人居环境安全的突出环境问题为重点,制定土壤污染治理与修复规划,组织开展治理与修复。实施严格的土壤环境质量保护、污染土壤的风险管控、高风险污染土壤的治理与修复是落实《土十条》的重要任务,也是建设我国土壤环境监管制度的重要内容。土壤环境标准是实施土壤环境管理的重要依据。本文基于《土十条》重要任务以及当前及今后一段时期国家土壤环境管理需求,以土壤环境管理需求为导向,探讨提出了包括土壤环境质量保护标准值、土壤环境风险管控标准值、污染土壤修复标准值的土壤环境标准值体系,可望为国家土壤环境标准体系的建立和标准制修订方法的发展提供技术参考。     

SENSORY RESEARCH FOR THE ESTABLISHMENT OF SECONDARY MAXIMUM CONTAMINANT LEVELS1

ABSTRACT: Individuals naturally engage in sensory evaluation of water quality during daily consumption. Efforts to ensure that all consumers receive high quality water must attend to sensory evaluation; otherwise individuals can obtain repeated evidence of compromised quality that reduces confidence in public purveyors and regulating agencies. Sensory quality is currently regulated by the United States Environmental Protection Agency (USEPA) by promulgation of secondary maximum contaminant levels (SMCLs) governing taste and odor in drinking water. Efforts to establish new SMCLs for identified organic contaminants has been thwarted by a lack of research data even though standardized methods for sensory evaluation presently exist. The present paper recommends a broad based national research program designed to produce odor detection thresholds, flavor detection thresholds, flavor acceptability functions, flavor recognition thresholds, and flavor intensity functions for each current contaminant of concern which will provide a substantial basis for the desired SMCLs, and offer an unprecedented comparative evaluation of currently standardized sensory evaluation procedures.

对松花江的治理应加强联合毒性效应研究

松花江水体的有毒有机污染较为严重,且有明显致癌、致突变和致畸作用的有机毒物种类繁多.水污染事故后,其污染状况变得更加复杂.针对主要污染物硝基苯是否与其它污染物之间发生联合毒性作用,文章提出应加强联合毒性效应研究;及建议制定标准时,尤其是排放标准,应适当考虑某些优先控制污染物之间的联合毒性作用.

Water technology for specific water usage

BACKGROUND: Water is the basis for life and culture. In addition to the availability of water its quality has become a major issue in industrialized areas and in developing countries as well. Water usage has to be seen as part of the hydrological cycle. As a consequence water management has to be sustainable. The aim of the contribution is to give water usage oriented quality criteria and to focus on the technical means to achieve them. MAIN FEATURES: Water is used for many purposes, ranging from drinking and irrigation to a broad variety of technical processes. Most applications need specific hygienic, chemical and/or physical properties. RESULTS: To meet these demands separation and reaction principles are applied. The reuse of water and the application of water treatment with little or no waste and by-product formation is the way to go. Membrane separation and advanced oxidation including catalytic reactions are promising methods that apply natural processes in sustainable technical performance. Thus elimination of specific water constituents (e.g. salts and metals, microorganisms) and waste water cleaning (e.g. pollutants, nutrients and organic water) can be done efficiently. OUTLOOK: Learning from nature and helping nature with appropriate technology is a convincing strategy for sustainable water management.
