Abstract

En 中文

• Spatially resolved PM measurements obtained using a multi-instrumented thermal manikin. • Apparent removal rates vary with location due to plume-driven transport. • Thermal plume enhances entrainment and accelerates personal exposure. • Chamber-average decay fails to represent near-body particle dynamics.
