Data relating to emissions of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) from industrial boilers

Polychlorinated-dibenzo-para-dioxins (PCDDs) and Polychlorinated-dibenzofurans (PCDFs) contamination in ecosystems has been a major concern, however, no information is available about the atmospheric contents and emission profiles in different types of fuels from industrial boilers in Thailand, Lao PDR, and Cambodia. Nine air and bottom ash samples (n = 18) were collected from three industrial boilers using U.S.EPA Method 23 and U.S.EPA Method 8290, respectively. All samples were successfully quantified by two High Resolution Chromatography-High Resolution Mass Spectrometry (HRGC-HRMS) namely Waters Autospec Premier and Waters Autospec Ultima. This investigation elucidates the impacts of fuel type on the emissions of PCDDs and PCDFs from three different industrial boilers. It appears plausible to affirm that fuel types play an important role on PCDD/PCDF emission levels from industrial boilers. The results of PCDD/PCDF concentrations should be considered as baseline data for promoting Best Available Technique (BAT) and Best Environmental Practise (BEP) in order to reduce dioxin emissions from industrial boilers in Southeast Asian countries.

Environmental Sciences More specific subject area Environmental Chemistry Type of data Table, text file, graph, figure How data was acquired Soxhlet extraction and High Resolution Chromatography-High Resolution Mass Spectrometry (HRGC-HRMS) (Waters Autospec Premier and Waters Autospec Ultima) [1] Data format Raw data, analysed. Experimental factors PCDD/PCDF congeners were collected by using probe and hotbox system, console and sampling line, glassware kit, and Horizontal Modified Accessories Kit (APEX). Extraction is conducted in Soxhlet equipment with the appropriate solvent [2]. The clean-up procedure could be different from sample to sample, but a schematic of a typical process is given in Table 1. Experimental features PCDD/PCDF congeners using HRGC-HRMS. Data source locations All samples were collected from industrial boilers located at the Great Honour Textile Factory Ltd. (GHT), OLEEN Company Limited (Oleen), and Lai Agro Industry Company Limited (LAI). GHT is an exporter from Cambodia, the company sell ladies and gentlemen knitted pullover. Oleen is The largest and modernest edible palm oil producer in Thailand with 100% Thai Investment of 850 Millions Baht. LAI is one of the leading canned sweet corn production company in Lao PDR. Data accessibility Data available within article.

Value of the data
Data can be employed as a base-line data for PCDD/PCDF concentration levels emitted from industrial boilers.
There is always the possibility of environmental contamination with toxic substances such as PCDD/PCDF congeners, therefore, continuous air monitoring is obviously crucial for occupational health workers.
Data displayed here may serve as benchmarks for other research groups focusing in the field of occupational safety and health, and toxicology to assess PCDD/PCDF congeners daily intakes by industrial emissions.
The results of this dataset can be useful for United Nations Industrial Development Organization (UNIDO) to showcase the success of "Demonstration of BAT and BEP in Fossil Fuel-fired Utility and Industrial Boilers in Response to the Stockholm Convention on Persistent Organic Pollutants (POPs)". Tables 1-3 show descriptive statistics of selected PCDD/PCDF congeners collected from Oleen, LAI,  and GHT, respectively. Tables 4-6 are demonstrating the bottom ash concentration of PCDD/PCDF  congeners collected at Oleen, LAI, and GHT, respectively. 2. Experimental design, materials and methods

Dataset area
All samples were collected from industrial boilers located at the Great Honour Textile Factory Ltd. (GHT), OLEEN Company Limited (Oleen), and Lai Agro Industry Company Limited (LAI) (see Table S1 and Fig. S2-S4 in Supporting material). All fuels used in three industrial boilers of GHT, OLEEN, and LAI were cashew wood, anthracite coal, and heavy oil grade C, respectively.
