Toxic release inventory database

Releases of mirex and chlordecone are not required to be reported under the Superfund Amendments and Reauthorization Act (SARA) Section 313 (EPA 1993a) consequently, there are no data for these compounds in the 1992 Toxics Release Inventory Database. 

TRI87. 1989. Toxic Release Inventory Database. National Library of Medicine, Bethesda, MD. 

No information is available in the Toxics Release Inventory database for facilities that produce HDI because this compound is not included under SARA, Title III and, therefore, is not among the chemicals that facilities are required to report (EPA 1995). 

Prior to January 1, 1995, facilities involved in the production or processing of diazinon were not required to report the amount of releases to various environmental matrices (EPA 1995a, 1995b). Data on diazinon releases for 1995 will be available in the Toxics Release Inventory database in 1997. 

Provides toxicology data for more than 130,000 chemicals in four categories substance identification toxicity/biomedical effects toxicology and carcinogenicity review and exposure standards and regulations. Built and maintained by the National Institute for Occupational Safety and Health (NIOSH) as a segment of the Toxic Release Inventory database. Available online, CD-ROM and computer tape from NIOSH and from commercial database vendors. 

Releases to air, land, and water occur primarily through its use as a restricted-use insecticide. The media of most importance for human exposure are contaminated air and soil. According to the Emergency Planning and Community Right-to-Know Act of 1986, 42 U.S.C. Section 11023, industries are required to submit chemical release and ofif-site transfer information to the EPA. The Toxic Release Inventory (TRI), which contains this information for 1987, became available in May of 1988. This database is updated yearly and provides a list of industrial production facilities and emissions. 

According to the Toxic Chemical Release Inventory database (TRl), an estimated total of at least 49 million pounds of trichloroethylene was released to air from manufacturing and processing facilities in the United States in 1988 (TRI88 1990). The level reported in 1993 was 30.2 million pounds (TRI93 1995). The number of reporting facilities in each state and the ranges within which individual facilities reported their releases are shown in Table 5-1. The TRI data listed in this table should be used with caution since only certain types of facilities are required to report. This is not an exhaustive list. 

Although this section does not present historical information regarding TRI chemical releases over time, note that, in general, toxic chemical releases have been declining.13 Although onsite releases have decreased, the total amount of reported toxic waste has not declined because the amount of toxic chemicals transferred offsite has increased. Better management practices have led to increases in offsite transfers of toxic chemicals for recycling. More detailed information can be obtained from U.S. EPA s annual Toxics Release Inventory Public Data Release book, or directly from the Toxic Release Inventory System database. 

The Toxics Release Inventory (TRI), which contains this information for 1996 became available in May of 1998 This database will be updated yearly and should provide a list of industrial production facilities and emissions. 

The Toxics Release Inventory (TRI), which contains this information for 1992, became available in May of 1994. This database will be updated yearly and should provide a list of industrial production facilities and emissions. Information in the TRI93 (1995) data base pertains only to U.S. industrial facilities that manufacture or process hydrogen cyanide. There is a need for similar information on releases and off-site transfer from facilities that manufacture or process other cyanide compounds covered in this profile. 

The Toxics Release Inventory (TRI) is a publicly available EPA database that contains information on toxic chemical releases and other waste management activities reported annually by certain covered industry groups as well as federal facilities. ... 

HDI and HDI prepolymers can be released to the atmosphere during spray applications of polymer paints containing residual amounts (0.5-1.0%) of monomeric HDI (Alexandersson et al. 1987 Hulse 1984 Karol and Hauth 1982). These substances could also be released to the atmosphere from waste streams from sites of HDI or polymer production. No information is available in the Toxic Chemical Release Inventory database on the amoimt of HDI released to the atmosphere from facihties that produce or process HDI because this compound is not included under SARA, Title 111, and therefore, is not among the chemicals that facilities are required to report (EPA 1995). There is also a potential for atmospheric release of HDI from hazardous waste sites however, no information was found on detections of HDI in air at any NPL or other Superfund hazardous waste sites (1996). Beeause of the relatively rapid reaction of HDI with hydroxyl radicals in the atmosphere an possible hydrolysis (see Seetion 5.3.2.1), significant atmospheric concentrations are not expeeted to oeeur exeept near emission sourees.
