Abstract

The water quality in the surface microlayer (SML) and subsurface water (SSW) in the Guangzhou segment of Pearl River, a eutrophic urban river section in China, were analyzed. The spatial and temporal dynamics of nutrient concentrations, heavy metals and bacteria were examined from 2 sampling sites in monthly samples throughout 2010. It is highlighted that the Guangzhou segment of the Pearl River suffers serious pollution from nutrients and heavy metals, as well as microbial contamination. The results indicate that the SML was enriched in nutrients, heavy metals and bacteria, with the maximum enrichment factor of 3.84 for nutrients, 8.00 for heavy metals, and 3.04 for bacteria, suggesting that the water quality of the SML of the Guangzhou segment of the Pearl River was more degraded than in the SSW
