For compounds of low volatility, a combination of the KNUDSEN effusion method and the LANGMUIR free evaporation method enables the precise measurement of vapor pressures over a wide temperature range. This is demonstrated for the fungicides Dichlofluanid and Tolylfluanid and the insecticide a-Endosulfan. Saturation concentrations were estimated and compared with results from test chamber experiments carried out under indoor conditions.enbiocidesvapour pressureemissionindoor airtest chamber674journal article
