초록

Veterinary antibiotics are frequently detected in soils posing potential contamination of food crops. Sulfamethazine (SMT) uptake was investigated by lettuce (Lactuca sativa L.) grown in the soils treated with/without biochar derived from an invasive plant, burcucumber (Sicyos angulatus L) (BBC700). Soils were contaminated with SMT at 5 and 50 mg kg(-1), and treated with/without 5% BBC700 (w w(-1)). The lettuces were harvested after 5 weeks of cultivation and were analyzed for SMT by a high performance liquid chromatography-tandem mass spectrometry after solid-phase extraction. With 5% BBC700, the uptake of SMT was reduced by 86% in the soil spiked with 5 mg kg(-1) SMT compared to the control whereas a 63% reduction was observed in the soil spiked with 50 mg kg(-1) SMT. Application of BBC700, into soils effectively reduced the SMT uptake by lettuce. (C) 2014 Elsevier Ltd. All rights reserved.
