Air-contamination by hexane used in extraction at work places in oil mills. Goal: elaboration of a gaschromatography measuring technique for work place monitoring
Work area analysis in five oil mills, ambient and personal air monitoring performed in the extraction or distillation area in accordance with technical rule (TRGS) 402
All procedural and substance-specific criteria for individual extraction processes were investigated. During continuous extraction processes the concentrations of n-hexane were less than 1/4 of the threshold limit value (in normal operation). During intermittent processes the values were about half the threshold limit value.
