It is written in four parts: Part A contains 9 chapters that describe the current knowledge of the physical science that underpins the process of aerosol sampling. Part B contains 4 chapters, which present the basis of standards for aerosols, including the link with human exposure by inhalation. Part C contains 7 chapters that cover the development of practical aerosol sa 606 $aAerosols 615 0$aAerosols. 676 $a628.5/30287 700 $aVincent$b James H$01344247 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911019337803321 996 $aAerosol sampling$93069054 997 $aUNINA
