Cytotoxic effect of PM2.5 extracts in BEAS-2B Cells. Cells were treated for 24 h with PM2.5 extracts collected in the Puerto Rican coast during the African storm (ADEPRC) and non-storm (Non-ADEPRC) season. LC50 (lethal concentration of the PM extracts that kills 50% of the cells in 24 h) values were determined. ADEPRC (LC50 = 122 mg/ml (extrapolated) and Non-ADEPRC (LC50 = 191 mg/ml (extrapolated) were cytotoxic. All extract concentrations were tested in 3 independent experiments
