- Abstract
Many sites of the world are currently faced with the prospects of air pollution. It is well established that photocopying machines generally contribute to the indoor emissions of Volatile Organic Compounds (VOCs) and Ozone that strongly influence the health of individuals. The current study aimed to discern the spatiotemporal variations of indoor Total Volatile Organic Compounds (TVOCs) and Ozone using a real-time monitoring approach in photocopying centers over mega-city of Pakistan. The real-time monitoring transcribed the diurnal variability of TVOCs and Ozone in photocopying centers (n = 200) during working hours (8:00 AM to 8:00 PM). Spatially, a high degree fluctuation was observed in the indoor level concentrations of TVOCs and Ozone. A typical diurnal cycle with a minimum value in the morning and a maximum in the noon with a gradual decrease until night was observed for TVOCs and Ozone suggesting that the photocopying emissions were a major source of generation. A significantly strong positive correlation was found between TVOCs and Ozone (r = 0.627, p < 0.001). The findings were compared with the available standards indicating the potential of health hazards to workers.
