Abstract This study was planned with the aim to understand the spatial distribution and pollution characteristics of nutrients and heavy metals in the surface sediments of major bays in Guangxi, for which 25 sediment samples were collected in August 2021 from Zhenzhu Bay, Qinzhou Bay and Lianzhou Bay. The contents of total nitrogen (TN), total phosphorus (TP), total organic carbon (TOC) and eight heavy metals (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) in the surface sediments were analyzed. The results showed that the variation coefficient of mean contents of TN, TP and TOC was 776.00, 206.33mg/kg and 0.41% in the surface sediments of Guangxi coastal area comprising of 53.35%, 64.78% and 47.33% variation respectively. The evaluation results of the nutrient pollution index and the organic pollution index for TN, TP and TOC in the surface sediments showed slight contamination. The average content of As, Cd, Cr, Cu, Hg, Ni, Pb and Zn in the surface sediment were 13.38, 0.058, 31.83, 13.71, 0.024, 13.18, 24.24, and 31.66mg/kg, respectively. The contents of 8heavy metals reached China’s national first-class benchmark of marine sediment quality. The result of geoaccumulation index (I_geo) found slight contamination of As, Cd and Ni in the three bays. The potential ecological risk index (RI) for heavy metals in surface sediments ranged from 17.77 to 133.88, with a mean value of 56.45, which portrayed minor potential ecological risk, especially from Cd and As, Hg, contributing 79.37% in the total RI. Our study concludes that the main sources of As, Cd, Cr, Cu, Hg, Ni, Pb and Zn in the surface sediments of major bays from Guangxi were from industries together with mining and aquaculture.
