Emission sampling for particulate matter and polychlorinated dibenzo-p-dioxin (PCDD) and polychlorinated dibenzofuran (PCDF) was conducted at 12 sites (Site A to Site L) as part of a study of emissions to air from secondary metals processes in New Zealand. The purpose and design of the sampling programme are discussed detail in Volume I.
K2 Environmental Ltd conducted the sampling for this study between September 2002 and May 2003.
This report summarises the information provided by K2 Environmental Ltd in particular, the details of the sampling including: sampling locations, sampling times, gas volumes and stack conditions.
The PCDD and PCDF results are reported as a concentration in ng/m3, as an emission rate in ng per hour and as an emission rate in ng per tonne of metal.
Production data used to calculate the emission factors in ng per tonne of metal is held by the Ministry for the Environment and can be made available on request. Similarly, as the laboratory sheets for the 30 PCDD and PCDF analyses (S1 to S30) conducted for this study, and comprising Appendix A, are not available in electronic form, a copy can be provided on request.
