PD-1 Certificate of Analysis

Certified Reference Material: Non-Ferrous Dust

Printable version of the certificate (PDF, 719.29 kb)

PD-1 is the result of cooperative effort, between CCRMP and the Air Pollution Technology Centre of Environment Canada, to prepare a non-ferrous dust from a base-metal smelter for use in a nation-wide, analytical quality-assurance program operated by the Federal/Provincial Committee on Air Pollution, and also to provide a reference material for laboratories concerned with the analysis of similar environmental samples.

PD-1 is a composite of samples of dusts from numbers 1 and 2 baghouses, and of a smaller sample of electrostatic-precipitator dusts collected from the zinc and copper roaster stacks of Hudson Bay Mining and Smelting Company Limited in Flin Flon, Manitoba. The material is essentially zincite containing varying minor to trace amounts of chalcocite, chalcopyrite, covellite, ferrites, galena, iron oxides, quartz, pyrite, pyrrhotite, sphalerite, elemental sulphur, and complex sulphates, silicates, and arsenates.

Twenty-six laboratories provided analytical results for one or more of lead, arsenic, and mercury.

A certificate of analysis will be issued with each order of PD-1. CANMET Report 81-7E, "PD-1: A certified non-ferrous reference dust", will be forwarded, free of charge, on request to the Coordinator, CCRMP.
