  1. Pengelolaan Polutan Udara di dalam Ruangan Oleh Sudrajat PPLH- Unmul 2003

  2. Bioaerosol Samplers • Numerous sampler types • Some adapted from dust or particle samplers • Some designed specifically for microbes • Few specifically for non-microbial bioaerosols (e.g. endotoxin), but generally thought samplers used for microbe collection are adaptable

  3. Bioaerosol Samplers • Gravitational samplers (e.g. settle plates) • No special equipment only coated microscope slide, agar plates, etc. • Passive (non-volumetric), relies on collection of particles by gravity settling • Oversamples for larger particles • Poor for collection in turbulent air; affected by turbulent deposition or shadowing

  4. Inertial Bioaerosol Samplers • Allow collection of particles by size selective sampling • Includes impactors, sieves, stacked sieves • Relies on particle tendency to deviate from air flow streamlines due to inertia • Particles deposited to solid or semi-solid surface
