Sampling and analysis of chlorpyrifos airborne residue emitted under treated field conditions

Ambient air sampling on 12-hour daytime before and immediately after chlorpyrifos application using mist-blower (Solo 412) was done by passive air sampling (cotton gauze, cellulose filter and PUF) and active sampling (PUF plug and quartz filter cartridges). During spray application, sampling was als...
