The study examines the near-field exposures and health risks of organic chemicals in interior paints commonly used in Sri Lanka. The researchers developed mass balance-based and high-throughput models to predict chemical emissions during wet and dry phases and integrated these models into the USEtox model for health risk assessment. The models accurately predicted indoor air concentrations and drying time. They found that inhalation is the primary exposure pathway, and exposure is much higher for painters during application than for household members during use. The study identified chemicals of concern and recommended the use of protective equipment for painters and increasing air ventilation rates to reduce exposure for household members.
