On February 2, 2021, Tang, Jinpeng; Fang, Ji; Tam, Nora Fungyee; Yang, Yang; Dai, Yunv; Zhang, Jinhua; Shi, Yuming published an article.Category: amides-buliding-blocks The title of the article was Impact of phytoplankton blooms on concentrations of antibiotics in sediment and snails in a subtropical river, China. And the article contained the following:
The present three-year field investigation on sediment in the eutrophic Pearl River in South China showed that concentrations of sulfonamides (SAs), fluoroquinolones (FQs), and macrolides (MLs) in the river areas where blooms occurred were 4.6, 2.4, and 3.4 times higher than those without blooms, resp., but the resp. concentrations of tetracycline (TC) and oxytetracycline (OTC) in the areas with blooms were 2.6 and 3.8 times lower than those without. Significant pos. correlations were found between concentrations of chlorophyll a in water and most antibiotics in sediment. Further investigation in each season suggested that lower diffusion but higher sinking were possible reasons driving the burial of sulfapyridine (SPD), sulfamethoxazole (SMX), and trimethoprim (TMP) in sediment from areas where blooms occurred, with burial rates up to 14.86, 48.58, and 52.19 g month-1, resp. Concentrations of TCs in both water and sediment were inversely correlated with phytoplankton biomass, which might be related to the enhanced biodegradation capacity of bacteria caused by phytoplankton blooms. Phytoplankton also affected concentrations of antibiotics in the snail, Bellamya purificata, with higher values in March but lower values in Sept. The concentration of antibiotics in snails pos. correlated with that in sediment when snails were dormant but with antibiotics in water after dormancy. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Category: amides-buliding-blocks
