Title Comparison of formaldehyde exposure levels in two multi-industry occupational exposure databanks using multimodel inference
Bibliographic information Jan. 2011, Vol.8, p.38-48. Illus. 42 ref.
Abstract This study compared formaldehyde measurements in the French (COLCHIC) and United States (IMIS) occupational exposure databases for 1986-2001 using multimodel inference. Modeled variables included data source, industry, year and sample type. The model set included 72 models corresponding to testing all variables and five interactions and estimation of 93 coefficients. Respectively, 3143 and 2646 IMIS and COLCHIC data, spread across 28 common industries, were analyzed. The full model explained 21% of the total variability. All fixed effects and the source-industry interaction were shown as strong predictors of exposure. The temporal trend (5% yearly decrease) and difference between short-term and long-term data (short-term greater than long-term by two-fold) were similar across the two databanks. Overall, the analysis showed that both databanks provide a similar multi-industry portrait of formaldehyde exposure despite a potential for very different occupational settings. The results offer encouraging insight about extrapolation of exposure data across countries.
