Industrial activities, chemicals from data sources

CSB searched over 40 data sources for incidents that met its definition of a reactive incident (Section 2.1). The data search focused on recent incidents (since 1980) where the primary cause was related to chemical reactivity however, the 1980 cutoff is not intended to diminish the important lessons learned from prior incidents. The search covered both chemical manufacturing (i.e., raw material storage, chemical processing, and product storage) and other industrial activities involving bulk chemicals, such as... 

The CEC s North American Pollutant Release and Transfer Register project tracks and publishes information on the amounts, sources, and handling of toxic chemicals from industrial activities in North America, including analyses of trends in pollutant releases and transfers since the early days of NAFTA. Each year the CEC publishes the Taking Stock" report and website, which provides a unique regional picture of pollutant data in North America, based on available data from the national PRTR systems. 

The Pollution Prevention Act of 1990 (PPA) requires facilities to report information about the management of TRI chemicals in wastes and efforts made to eliminate or reduce their quantities. These data on TRI have been collected annually from 1991. The data were meant to provide a basic understanding of the quantities of toxic waste handled by the industry, the methods typically used to manage them, and recent trends in these methods. TRI waste management data can be used to assess trends in source reduction within individual industries and facilities, and for specific TRI chemicals. This information could then be used as a tool in identifying opportunities for pollution prevention compliance assistance activities. 

In an attempt to provide this focus, forty-seven active receptor model users from government, university, consulting and industry met for 2 1/2 days in February 1980 it. They addressed the models and the information required to use them in six separate task forces 1) Chemical Element Balance Receptor Models, 2) Multivariate Receptor Models, 3) Microscopic Identification Receptor Models, 4) Field Study Design and Data Management, 5) Source Characterization, and 6) Analytical Methods. The objectives of these interrelated task forces were to ... 

The emission inventory of dioxin-like compounds in South Korea was determined during two preliminary studies (KMOE, 2001, 2002a). For emission factors, the preliminary study (KMOE, 2001) adopted measured values for waste incinerators and the values of UNEP chemicals Toolkit (UNEP Chemicals, 2001) for the other sources. Estimated PCDDs/DFs emission in 1999 ranged from 1163 to 1595 g I-TEQ yr-1 due to uncertainties in emission factors and activities (Table 2.6). Besides the preliminary estimate, since the late 1990s extensive measurements of PCDDs/ DFs have been performed at waste incinerators and the emission data by 2004 had been compiled for 1800 incinerators. Moreover, nationwide industrial sources have been investigated every year since 2001 34 fer-rous/non-ferrous metal production factories in 2001, 114 non-ferrous metal and mineral production factories in 2002, 73 chemical/energy/ landfill factories and crematories in 2003, and 63 municipal wastewater treatment plants and 9 types of vehicles in 2004. By 2005, measurements of total dioxin emissions had been made on 288 industrial sources. Based on these measurements, KMOE made the first official estimate of PCDDs/DFs emission in South Korea. It has been estimated that the total PCDDs/DFs emission was 1021 g I-TEQ yr-1 in 2001 (KMOE website) (Table 2.6). This emission was approximately 62% of that...
