Figure 4

The spearman correlation matrix for the MMA illustrates the relationships between PAHs, NPAHs, meteorological parameters, and pollutants. The matrix shows strong positive correlations between HMW PAHs and RH and negative correlations with T and SR. The positive correlation between 3N-FLA and SO\(_{2}\) is notable, suggesting sources linked to vehicular emissions.
