Book Abstract

第1章简介
1.3 污染
我们对污染都有一定的概念,但你知道如何定义它吗?
DQ 1.1 如何理解污染的定义?
回答:下面的定义来自经济合作与发展组织,污染就是由人类直接或间接排放到环境中对环境造成不利影响的物质或能量,这些不利影响包括对人类健康的威胁、对生物资源的破坏、干扰环境的舒适性和对环境的不合理利用。
当将注意力集中于污染的化学特征之前,记住这并不是污染的唯一形式。噪声是物理污染的一种。把和周围环境温度不同的水排入河流中将影响河流中的生物,这是热全球变暖。硝酸盐的生成是环境中氮自然循环的一部分(见图1.1),然而,化肥的过污染的一种形式。然而污染常和排入环境中的化学物质联系在一起。通常的观点认为这些是非天然的(因而也是有害的)物质。近来最著名的一个例子就是氯氟烃(CFCs)的排放问题。氯氟烃被用于喷雾剂及其他用途。氯氟烃的排放和平流层臭氧的消耗有关,从而导致了由太阳辐射到地球表面的有害紫外辐射强度增加,进而使皮肤癌发病率增加。尽管在发达国家氯氟烃的生产已停止,但从大气中消除现有的氯氟烃还需要很长时间,同时和臭氧消耗有关的化合物例如含氢氯氟烃(HCFCs)还在生产,因此对臭氧层的影响还将持续许多年。
更为常见的问题是人们往环境中排放环境中已有的物质,而引起环境中此种物质的浓度高于天然本底值。二氧化碳是大气的组成部分,由生物体的呼吸产生。由于化石燃料的燃烧引起大气中二氧化碳浓度增加,而可循环利用二氧化碳的森林数量减少,从而导致全球变暖问题。其他大量的天然气体(例如甲烷和氮氧化物)的增加加剧了量使用会使水体中富集大量的硝酸盐,首先这会引起水生植物的过度生长,最终导致水体中所有物种的死亡。这个过程就是人们所熟知的富营养化。除了氮本身,如果氮循环中的其他形态在水体或大气中的浓度大大超过它的天然本底值,都将引起环境问题。表1.1总结了这一点。
Introduction

目前,国内环境科学与环境工程本、硕课程体系建设亟待加强。环境监测技术、管理体系涉及全球、国家、区域等不同的时空尺度。发达国家与发展中国家在相关资源、技术方法的掌握上不对称。因此,通过引进国际上优秀教材,对于了解并解决国内上述问题,特别是在环境监测标准方法的建立与推广使用如何与国际接轨上有积极的作用。
本书自2002年开始作为厦门大学环境科学与工程专业大三双语课程《环境监测》的教材。因其叙述采用对话方式进行,使读者仿佛置身其中,任课教师和使用过该教材的本科生均感其效果颇佳。因此,其编译尽可能保持原著风格,以使本专业的本科生、研究生及相关从业人员尽快熟悉、掌握新知识及专业英语,并为国际上有关新知识、新方法的学习、融会贯通搭起一座桥梁。
该原版教材于2002年出版,体现了当今环境分析与环境监测的新技术、新方法及相关的管理理念。作为专业课教材,其突出的特点是强调理论与实践的结合、管理与技术结合。同时,其内容的安排、进程、对一些问题的思考均具有不同于国内教材的鲜明特色。
该教材整理出版过程中得到了厦门大学有关部门、院、系相关领导的大力支持。慕俊泽、任锋、陈佳宁、肖翔、彭景吓、王萍、罗剑梁参与了部分章节的翻译整理工作。在此,一并致以真诚的感谢。
因译者水平所限,其中难免有不尽之处,敬请指正。
