The spatial characteristics and pollution levels of metals in urban street dust of Beijing, China.

Highlights: [·] We explored the pollution characters of metals in street dust of Beijing. [·] Area-source pollution and point-source pollution exist simultaneously. [·] We identified the spatial autocorrelation intensities and ranges of metals. [·] Metal pollution anomalies were identified by cluster and outlier analyses. [·] Urban activities strongly influence the distributions of metals. [ABSTRACT FROM AUTHOR]
