检测水中亚硫酸还原厌氧梭菌孢子的培养液富集法

水体中亚硫酸协还原菌的孢子，能在水中生存较长时间，容易在水池或管道中滋生，产生黑臭，可作为水体长期或周期性污染的一种指示，但目前国内尚无测定该菌的完整方法，作者建立了一种比较适合我国国情的测定方法，以国产蛋白陈替代胶胨型的水解液，结果阳性特征明显，精密度，重现性均较好。     

济南市水文地质特征对地下水污染的影响分析

从环境水文地质学的角度出发，对济南市地下水污染的主要途径和方式，以及局部地下水重污染区进行了较为详细的分析，济南市地下水污染以浅层地下水污染为主，局部地区深层地下水也已受到污染，并有进一步加重的趋势，地下水严重超采，造成多处地表塌陷和降落漏斗，并成为济南市地下水的重污染区。

Fisheries management: integrating societal preference, decision analysis, and ecological risk assessment

Fisheries management is the practice of analyzing and selecting options to maintain or alter the structure, dynamics, and interaction of habitat, aquatic biota, and man to achieve human goals and objectives. The theory of fisheries management is: managers or decision makers attempt to maximize renewable `output' from an aquatic resource by choosing from among a set of decision options and applying a set of actions that generate an array of outputs. Outputs may be defined as a tangible catch, a fishing experience, an existence value, or anything else produced or supported by renewable aquatic resources. Overall output is always a mix of tangible and intangible elements. However defined, management goals and objectives are essential components of fisheries management or any other field of renewable natural resource management. Reaching consensus on management goals and objectives has never been a simple task. Beyond the broad and often conflicting goals of an agency, managers must decide who should set specific management objectives — agency personnel, the public, or a combination of the two. Historically, rhetoric aside, fisheries managers in North America nearly always have consulted with professionals in governmental roles to set management objectives. In a strongly pluralistic society, this often resulted in protracted political and legal conflict. Increasingly, there are calls for use of risk assessment to help solve such ecological policy and management problems commonly encountered in fisheries management. The basic concepts of ecological risk assessment may be simple, but the jargon and details are not. Risk assessment (and similar analytical tools) is a concept that has evoked strong reactions whenever it has been used. In spite of the difficulties of defining problems and setting management objectives for complex ecological policy questions, use of risk assessment to help solve ecological problems is widely supported. Ecological risk assessment will be most useful (and objective) in political deliberations when the policy debate revolves around largely technical concerns. To the extent that risk assessment forces policy debate and disagreement toward fundamental differences rather than superficial ones, it will be useful in decision making.
