  • Consumer concerns on food safety and society awareness of chemical contaminants in the environment have increased in the past few years. As a consequence, more restrictions in the use of chemical products have been imposed at national and international levels. Pesticides are widely used for the control of weeds, diseases, and pests of cultivated plants all over the world, mainly since after Second World War, with the discovery of some organic compounds with good insecticide or herbicide activity. At present, around 2.

  • The most significant issues facing mankind today are related to the quality of our environment. Past decisions did not always consider environmental factors as critical elements. However, current decisions made daily should reflect the importance of the environment. All environment-related issues are multidisciplinary, ranging from science and engineering to social, economic, and regulatory issues. Further, these issues are not related to any one region or country, but are global in nature, requiring multidisciplinary, multiorganizational, and multinational educational efforts....

  • My interest in environmental pollution control microbiology began at MIT in 1948 when I realized that very little was known about this vital area of sanitary engineering technology. I became a serious student of environmental pollution control microbiology in 1950 when I began research on the microbiology and the biochemistry of floe-forming bacteria in activated sludge. I must admit that environmental pollution control microbiology has been my area of technical specialization since 1950. It has been a most interesting experience that I have never regretted.

  • The contents of this book are based loosely on presentations at a special symposium, “Application of Interface Science to Environmental Pollution Control,” held as part of the ACS National Meeting in Chicago, August 26–30, 2001. This symposium offered an opportunity for researchers from a range of disciplines to discuss the role of interface science in environmental remediation. The development of an archival book based on this meeting is a timely contribution to a burgeoning area of research that is now attracting the attention of a diverse research community.

  • A preliminary study was carried out in mid 1999 on the status and potential impact of the introduction of exotic fish species in the Mekong Basin. Introductions have been made for four main purposes: aquaculture, stocking into lakes and reservoirs, pest control (mosquito) and the aquarium fish trade. Introductions of exotic species and movements of large quantities of fish for stocking are accompanied by risks to the environment, the possibility of native fish species declining through competition, predation or genetic interference, and the possible spread of disease....

  • In the early 1970s, the United States government identified and became wary of hazardous materials in soil, surface water, groundwater, and building structures. Most of these contaminants resulted from the evolution of technology without the benefit of chemical regulatory controls. The cost for cleanup of such sites was projected to exceed a trillion dollars, the burden of which was to be borne by the taxpayer and responsible parties. The term “responsible party” is a broad term but, in the final analysis, a responsible party is usually a property owner....

  • Economists have long advocated pollution taxes as a policy to improve water quality. One of the reasons water effluent taxes are embraced by economists interested in market-based policies is that sources of water pollution are varied and difficult to assess individually in terms of control costs. In principle, taxes overcome this problem. With a price—the tax—applied to pollution emissions, firms compare the price to their costs of emissions control. If the price is higher than control costs, they reduce emissions rather than pay the tax.
