Shipment of hydrazine solutions is regulated in the United States by the Department of Transportation (DOT) which classifies all aqueous solutions between 64.4 and 37% N2H4 as "Corrosive" materials with a subsidiary risk of "Poison". Hydrazine has been identified by both the Environmental Protection Agency and the DOT as a hazardous material and has been assigned a reportable quantity (RQ) of 0.450 kg (1 lb) if spilled. Dmms for the shipment of these solutions must bear both the DOT specification "Corrosive" and "Poison" labels in association with the markings "RQ Hydrazine Aqueous Solution UN 2030." Aqueous solutions of 37% concentration or less are a hazard Class 6.1, UN 3293, Packing Group III and require "Keep Away From Food" placards and labels.

In the United States, the Resource Conservation and Recovery Act of 1976 (RCRA) is the major legislation covering the disposal of solid and hazardous wastes (2). This act provides a multifaceted approach to solving the problems associated with the generation of approximately 5 billion metric tons of solid waste each year in the United States. It places particular emphasis on the regulation of hazardous wastes. This law established the Office of Solid Waste within the Environmental Protection Agency and directed the agency to publish hazardous waste characteristics and criteria. 

Atmospheric emissions of sulphur dioxide are either measured or estimated at their source and are thus calculated on a provincial or state basis for both Canada and the United States (Figure 2). While much research and debate continues, computer-based simulation models can use this emission information to provide reasonable estimates of how sulphur dioxide and sulphate (the final oxidized form of sulphur dioxide) are transported, transformed, and deposited via atmospheric air masses to selected regions. Such "source-receptor" models are of varying complexity but all are evaluated on their ability to reproduce the measured pattern of sulphate deposition over a network of acid rain monitoring stations across United States and Canada. In a joint effort of the U.S. Environmental Protection Agency and the Canadian Atmospheric Environment Service, eleven linear-chemistry atmospheric models of sulphur deposition were evaluated using data from 1980. It was found that on an annual basis, all but three models were able to simulate the observed deposition patterns within the uncertainty limits of the observations (22).

From October 1982 to October 1983, the Emergency Planning and Response Branch of Region 7 of the United States Environmental Protection Agency and its contractors collected approximately 8,000 environmental samples for analysis of 2, 3, 7, 8-tetrachlorodibenzo-para-dioxin... 

The authors and editors of this book wish to acknowledge the U.S. Environmental Protection Agency and the Electric Power Research Institute, who sponsored a Society of Enviromnental Toxicology and Chemistry (SETAC) workshop in September 2003 in Pensacola, Florida. More than 30 international experts gathered to discuss and propose a framework for a national mercury monitoring program to evaluate the effectiveness of mercury emissions controls on mercury concentrations in the enviromnent. This book and a companion journal publication (Mason et al. 2005) are the products of the workshop and subsequent efforts. 

During the media blitz that followed, Patterson urged the public to buy Chicken of the Sea tuna because the Van Camp Sea Food Company s molded steel cans were lead-free. With characteristic bluntness, Patterson lambasted a host of government laboratories from the Environmental Protection Agency and its Bureau of Foods to the National Marine Fisheries Service and the Food and Drug Administration (FDA). Asked if any other laboratories agreed with his findings, Patterson declared loftily that scientific questions are not determined by majority vote. 

Analytical chemistry is a critical component of worker safety, re-entry, and other related studies intended to assess the risk to humans during and subsequent to pesticide applications. The analytical aspect takes on added significance when such studies are intended for submission to the U.S. Environmental Protection Agency and/or other regulatory authorities and are thus required to be conducted according to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) Good Laboratory Practice (GLP) Standards, or their equivalent. This presentation will address test, control, and reference substance characterization, use-dilution (tank mix) verification, and specimen (exposure matrix sample) analyses from the perspective of GLP Standards requirements.

During the 2002 World Summit on Sustainable Development (WSSD), the U S. National Academies, the U.S. Environmental Protection Agency, and the American Chemistry Council announced a new initiative to facilitate better communication among scientists, policymakers, and other decisionmakers so that scientific knowledge more effectively informs public policy and private sector decisions relating to sustainability in developing countries. More specifically, the goals of the initiative are ...

The purpose of this chapter is to describe well-established analytical methods that are available for detecting and/or measuring and/or monitoring total petroleum hydrocarbons and their metabolites, as well as other biomarkers of the exposure and effect of total petroleum hydrocarbons. The intent is not to provide an exhaustive list of analytical methods. Rather, the intention is to identify well-established methods that are used as the standard methods approved by federal agencies and organizations such as the Environmental Protection Agency and the National Institute for Occupational Safety and Health (NIOSH) or methods prescribed by state governments for water and soil analysis. Other methods...
