Detection of traces of toxic chemicals in drinking water supplies, in polar ice caps, groundwater sources and episodes such as those in Minamata Bay, Japan and Love Canal, USA have focussed the attention of the public worldwide on the risks posed by the inappropriate disposal of hazardous waste and accidental release of toxic chemicals into the environment. In India regulations to control and m...

With the passage of the Resource Conservation and Recovery Act RCRA and the subsequent amendments to RCRA e orts to provide tighter controls on the transportation and disposal of hazardous waste have been steadily gaining ground This paper intended as a decision support tool for regional planning incorporates information on the hazardous waste generation treatment capacity and the costs of wast...

An approach for the analysis and management of multiple criteria critical infrastructure problems is put forth. Nuclear waste management involves complex tradeoffs under uncertainty. Among all waste either generated by nature or human activities, radioactive nuclear waste is the most toxic to human health and difficult to manage: it is known that some nuclear waste material will be radioactive ...

This report discusses various types of environmental waste products, current status of waste destruction, and the application of plasma technology for waste treatment. Plasma processes are divided into three types: open bath systems, shaft furnaces, and gas-cracking systems. These three types of plasma systems have the capability of treating a large number of different types of wastes and reduc...

In recent history the volume of electronic products purchased by consumers has dramatically escalated. As a result this has produced an ever-increasing electronic waste (E-waste) stream, which has generated concerns regarding the E-waste's potential for adversely impacting the environment. The leaching of toxic substances from obsolete personal computers (PCs) and cathode ray tubes (CRTs) of te...

The ever increasing pile-up of electronic waste in dumping sites, especially in developing countries such as China, Pakistan, India and several African countries, might have caused a significant alteration in the microbial community of the contaminated sites. This change in the microbial population may have significant impact to the soil ecology function. The major pollutants of electronic wast...

The University of Georgia recognizes that laboratory waste may have adverse effects on the environment. A university-wide program has been directed at reducing the improper storage and disposal of toxic chemical wastes. The program extensively utilizes the Code of Federal Regulations 49, Transportation Parts 100 and 199. This code serves as a guide for the packaging and disposal, in an approved...

The incineration of municipal waste has been the subject of controversy for many years and has been widely opposed because of concerns about the pollution of the air with toxic materials, particularly dioxins. Many incinerators have had to stop operation and many projects have been abandoned. At the same time, communities continue to be faced with the challenge of handling growing amounts of wa...

Toxic Chemicals These substances are hazardous to human health and the environment. In 2004 North American industrial facilities generated over 5 million tonnes of toxic chemicals as production-related pollutants and waste (see box). Despite this large amount, data for comparable industries and chemicals in Canada and the United States reveal encouraging trends. Over the period 1998–2004, total...

Dyes are one of prevalent types of chemicals used by human being today. Dyes are organic compounds which have complex aromatic molecular structure that make them toxic and harmful. When these dyes introduced with water due to textile dyeing and printing industrial waste water may cause problems to all living organism. In these dyes highly toxic metals are used as mordents so the removal of thes...
