Oxidative potential of indoor and outdoor particles collected over continuous 4-day periods at the research house during normal operating conditions and varied indoor conditions (high temperature; high RH; high temperature and high RH; high air change rate, and presence of cooking activities). (a) OPEPR per volume of air sampled, (b) OPEPR per mass of particle sampled. Error bars denote standard deviation of triplicate samples. Dotted lines denote the average outdoor and indoor OPEPR concentrations during sampling events with “normal conditions”.
