Antibiotics Contaminate the Lakes around the World: Chinese Scientists

  • A group of Chinese researchers from Xinjiang Institute of Ecology and Geography (XIEG) of the Chinese Academy of Sciences, and their collaborators have discovered the presence of at least seven types of antibiotics in both lake water and lake sediment globally. The antibiotics are present in higher concentration across the water sources. The findings have been published in ‘Environment International’.

    The scientists performed a comprehensive review of antibiotics and antibiotic resistance genes (ARGs) in lakes around the world.

    "Our meta-analysis shows that sulfamethoxazole, sulfamerazine, sulfameter, tetracycline, oxytetracycline, erythromycin, and roxithromycin were found at high concentrations in both lake water and lake sediment," said Dr. Song Wenjuan from XIEG who led the study.

    "Long retention times in lakes mean pollutants from discharges slowly circulate around the lakes and may lead to high ecological risk for ecosystems and human health," added Song.
