Screening questionnaire for selection of sampling sites for assessment of risks from combined exposure to multiple chemicals in indoor air

Overview

This screening questionnaire was developed to facilitate the selection of sampling sites for assessment of risks from combined exposure to multiple chemicals in indoor air in public settings for children. It addresses indoor and outdoor factors relevant to indoor air pollution, and uses a simplified approach to answering questions (‎yes/no)‎. Public-health workers can use the questionnaire to select sampling sites in schools, kindergartens and day-care centres where indoor air pollution is a concern.
