Exploring the Potential of Co-Application of Sewage Sludge, Chinese Medicinal Herbal Residues and Biochar in Minimizing Human Exposure to Antibiotics Contamination in Edible Crops

Agricultural practices such as wastewater irrigation and manure application may contaminate soils with antibiotics and, consequently, lead to human health risk. The co-application of three waste-derived materials, sewage sludge (SL), Chinese medicinal herbal residues (CMHR) biochar (BC), a soil amendment was proposed recently for minimizing the antibiotic amount in crop tissues. fate six antibiotics—amoxicillin, tetracycline, sulfamethazine, norfloxacin, erythromycin chloramphenicol—were investigated greenhouse soil-plant system fruit species: tomato. pots were mixed 5%, 10% or 20% SL-BC SL-CMHR-BC irrigated 3 μg/L 30 antibiotics. pot containing captured lowest concentration tomato Norfloxacin most abundant fruits, followed by tetracycline. significantly lowered bioconcentration factor fruit, while its effects on translocation more varied. Current some previous data used assess risk consuming carrot, lettuce estimated daily intake suggested negligible general compared acceptable intake, except CAP. A helps minimize exposure contamination edible crops.
