Spatial autocorrelation and temporal variation of contaminants of emerging concern in a typical urbanizing river

Yiqing Zhang et al.

Summary: The distribution and fate of contaminants of emerging concern (CECs) in the Houxi River were studied in relation to hydrological conditions, land use characteristics, and spatial contiguity. It was found that land use types related to anthropogenic activities were positively correlated with the presence and concentration of CECs. Significant annual variations were observed in both the concentrations and detection frequencies of CECs, with higher concentrations and detection frequencies downstream compared to upstream. Spatial variations were mainly influenced by downstream sites, and strong spatial autocorrelation was observed among connected sites. The results provide valuable insights for policymakers in managing and prioritizing CEC contaminants in the Houxi watershed.
