Introduction Steroid hormones are widely present in the environment and pose potential risks to organisms. Previous studies of steroid have predominantly focused on terrestrial environments, with few conducted marine environments. Methods In this study, we analyzed occurrence 44 seawater, sediment, organisms collected from coast Guangdong, China. Results Total concentration ranged 0.11 30.15 ng/L ND 8.58 ng/g (dw) sediments, 80.52 (ww) The highest average concentrations detected were progestins, estrogens, glucocorticoids, respectively. hormone seawater significantly higher during dry season than rainy season. Guanghai Bay, Pearl River Estuary, Daya Zhelin Bay those other bays. Discussion Negative correlations observed between salinity, indicating a continental input. Risk assessment results indicated that 17α-ethinylestradiol posed high risks. Nevertheless, consumption seafood does not significant health risk humans. To best our knowledge, is first study concurrently analyze androgens, estrogens water, diverse
