| 520 | 3 |a"A national interlaboratory quality control study for Canadian laboratories on the determination of eight acid herbicides (MCPA; 2,4-DP; 2,4-D; silvex; MCPB; 2,4,5-T; 2,4-DB; and picloram) in natural fresh water is described. The data show that most laboratories have acceptable expertise for the analysis of silvex; 2,4,5-T; and 2,4-D. No data were reported for MCPB by any laboratory, while only a few participants reported results on MCPA; 2.4-DP; 2,4-DB; and picloram. The overall results indicate that most participants in this study had not attempted the analysis of all eight herbicides. This may reflect the limited expertise in multi-residue analysis of these herbicides in water at the designed concentrations"--Abstract, page v. |
