For compounds of low volatility, a combination of the Knudsen effusion method and the Langmuir free evaporation method enables the precise measurement of vapour pressures over a wide temperature range. This is demonstrated for the compounds dichlofluanid, tolylfluanid and alpha-endosulfan. Saturation concentrations were estimated and compared with results from test chamber experiments carried out under indoor conditons.enbiocidesvapour pressureemissionindoor air qualitytest chamber674conference paper
