Research Shows the New Perspective in Bioaccumulation and Trophic Transfer of Both Free and Conjugated Antibiotics within an Estuarine Food Web

Journal of Hazardous Materials published a paper by the research team led by Dr Xu Xiangrong, a researcher at the South China Sea Institute of Oceanology, Chinese Academy of Sciences, about the new progress in the study of the biological enrichment mechanism of antibiotic conjugates in estuarine food webs. The first time confirmed the transmission patterns of conjugated antibiotics in estuarine food webs.

Antibiotics are widely used as antimicrobial drugs for treating human and animal diseases and are also being used in livestock and aquaculture to enhance the growth of animals. Due to the incomplete absorption of antibiotics entering the human bodies and animals, a significant portion is excreted into the environment through urine and feces in the form of parent compounds or metabolites, and have been frequently detected of these substances in the environment. This research revealed the characteristics of bioaccumulation and different forms of antibiotics in aquatic organisms and patterns in estuarine food web transmission will contribute to a more accurate assessment of the health and ecological risks posed by antibiotics.

 

The research results indicate the presence of conjugated antibiotics within organisms should be noticed. Quantifying free-form antibiotics solely would significantly underestimate the ecological and health risks of antibiotics in the environment.

 

Dr. Xu Xiangrong, the paper's corresponding author, stated that this research first confirmed the transmission patterns of conjugated antibiotics in estuarine food webs. It deepens the understanding of the bioaccumulation characteristics and transmission patterns of different forms of antibiotics in estuarine food webs, providing essential foundational data and technical support for accurately assessing the ecological and health risks of antibiotics.
