Linking PM2.5 organic constituents, relative toxicity and health effects in Puerto Rico

This research investigates ambient air samples, the chemical compositions, and the potential toxicity of inhalable particulate matter PM2.5 from the municipalities on the south, north, and east coast of Puerto Rico. Ambient air samples from Guayama, Ponce, Guayanilla, Bayamón and Humacao were studie...
