Chemical composition of indoor and outdoor PM_2.5 in the eastern Arabian Peninsula.

ABSTRACT: Water-soluble and trace metal species in fine particulate matter (PM_2.5) were determined for indoor and outdoor environments in Doha, Qatar. During the study period, PM_2.5 concentrations showed significant variability across several indoor locations ranging from 7.1 to 75.8 μg m^-3, while the outdoor mass concentration range was 34.7-154.4 µg m^-3. The indoor and outdoor PM_2.5 levels did not exhibit statistically significant correlation, suggesting efficient building envelope protection against outdoor PM_2.5 pollution. Rather than outdoor sources, human activities such as cooking, cleaning, and smoking were the most significant influence on chemical composition of indoor PM_2.5. NH₄⁺ concentrati
