Long-term average suspended particulate concentrations in Smokers' homes

Abstract
Suspended particulate matter (SPM) concentrations were measured in about 100 homes in the city of Arnhem, The Netherlands. Most homes were sampled for 2 months continuously. Monthly average SPM concentrations ranged from 20–570 μg/m3. From 26 houses, smoking data were gathered at a later date. A clear relationship was found between SPM concentrations and number of smokers in the home.
