Flett Research Ltd. has been performing ultratrace level mercury measurements since 1991. Our
client base is international and includes universities, provincial, state and
federal government departments, electric power utilities, mining companies and
private consulting firms. We have been the major contractor for the
international 5 year government/multiuniversity ELARP
mercury study (Experimental Lakes Area Reservoir Project) headed by Dr. John
Rudd of the Freshwater Institute, Winnipeg (Fisheries and Oceans). The long
term followup mercury analyses continue to be
performed by us. We were the key mercury lab for the FLUDEX project (FLooded Uplands Dynamics EXperiment)
headed by Dr. Drew Bodaly of the Experimental Lakes Area Research Station.
Mercury analyses are also being provided for the METAALICUS Study (Mercury
Experiment To Assess Atmospheric Loading In Canada and
the
Our lab recently successfully participated in
the International Intercalibration Exercise for
Mercury Speciation in Natural Waters, sponsored by EPRI. In 1997 Flett Research
Ltd. was one of only 12 labs in the world selected to take part in a validation
study for EPA Draft Method 1631 ("Total Mercury in Water by Oxidation,
Purge and Trap, and CVAFS"). We have participated in a number of IAEA
certifications of total and methyl mercury in reference materials. Regular and
successful analysis of total mercury in fish proficiency samples from the
Mercury Quality Assurance Program (MQAP – Canadian Food Inspection
Agency) indicates a continuing reliability in our mercury data. In relation to total
and methyl mercury analysis, we are accredited by the Canadian Association for
Laboratory Accreditation (CALA) to ISO/IEC 17025 for specific
tests. A copy of our accreditation certificate can be seen here.
Total mercury measurements are based upon the
SnCl2 reduction method, gold amalgam trapping, with
fluorescence detection (EPA1631e). Elemental Hg is done the same way, but SnCl2 is
omitted. Methyl mercury measurements employ an ethylation
step followed by purge and trap/GC separation and fluorescence detection
(EPA1630).
We have recently demonstrated the accurate measurement of Hg in small tissue biopsies (< 50 mg) thus permitting live fish to be non-lethally sampled and returned in good health to the water. This technique will be of interest to agencies that are responsible for continuous monitoring of mercury concentrations in fish populations. (Baker et al., Evaluation of Non-lethal Methods for the Analysis of Mercury in Fish Tissue, Transactions of the American Fisheries Society, 133:568-576)
Our sampling protocol for the collection of water samples requires the use of acid cleaned Teflon or glass bottles and clean room gloves. We will give advice on the correct selection of bottles, and may be able to supply limited numbers of precleaned Teflon bottles. Gloves can be supplied to our clients at a cost of $ 2.00 per sampling location (assuming that there are 2 persons on a field crew involved in sample collection). If water samples cannot be shipped to us cold within 48 hours, then they should be preserved with low Hg HCl (pre-analyzed and supplied by Flett Research) to 0.2% . The HCl is supplied at a cost of $50.00.
Results are typically available within 2 weeks of sample receipt.
