Chinese team finds high concentrations of seven antibiotics in Chinese lake waters and sediments

A team around SONG Wenjuan  from Xinjiang Institute of Ecology and Geography, LIN Hui from Zhejiang Academy of Agricultural Sciences and other researchers investigated the occurrence and distribution antibiotics and antibiotic resistance genes in Chinese and global lakes. The meta-analysis showed that seven antibiotics (sulfamethoxazole, sulfamerazine, sulfameter, tetracycline, oxytetracycline, erythromycin, and roxithromycin) were found at high concentrations in both lake water and lake sediments. No significant difference in sulfonamides concentration, but a significant difference in quinolones was found in lake water from China and that from other countries worldwide.  There was no significant difference in the concentration of sulfonamide resistance genes (sul1 and sul2) in lake water and river water.
