2008 Dioxin and Dioxin-like Compounds and TEQ Data Files
Data File Description
Six data files are being made available to represent the reporting year 2008 Dioxin and Dioxin-like Compound TEQ and individually reported mass quantity data. The individual mass quantity data or congener data is taken directly from the new Schedule One form that was introduced in reporting year 2008. The TEQ data is calculated from the individual mass quantity data and associated Toxic Equivalency Factors (TEFs). This data is complex. Breaking it down into six data files is an attempt to divide it into logic components that can be used to better understand it and to make the process of calculating the TEQ values transparent and re-creatable. In addition, in an effort to bring context, greater understanding and the ability to relate the data to other data elements, some of the files contain data from parts of the standard Form R.
Providing data in one large national file as well as individual state files has been a common practice for TRI when disseminating its data. However, for the new Schedule One Dioxin and Dioxin-like compound data and the resulting TEQ data, TRI will not be providing individual state files. TRI will only disseminate one set of files, each representing the entire country (i.e. national files). The reason for this is that the national files containing the data are small and will easily fit within a standard spreadsheet application. Users can easily load and delete any unwanted data at their discretion.
