Veterinary antibiotic residues in surface runoff flowing through vegetative buffer strip plots located at the University of Missouri Bradford Research and Extension Center (Columbia, MO) in September 2020

Vegetative buffer strips have been demonstrated to effectively reduce loads of sediment, nutrients, and herbicides in surface runoff, but their effectiveness for reducing veterinary antibiotic loads in runoff has not been well documented. Surface runoff simulation where performed to determine the effectiveness of Vegetative buffer strips vegetation and width on surface runoff loads of the veterinary antibiotics sulfamethazine and lincomycin. The three datasets in this release document 1. physical and chemical soil properties for soil located on experimental vegetated buffer strip plots prior to surface runoff simulations; 2. Rainfall simulator performance data and antecedent soil water content data for all vegetated buffer strip plots during the surface runoff simulations; and 3. Surface water hydrology data collected for determining veterinary antibiotic residue load concentrations and suspended sediment load concentrations in all vegetated buffer strip plots during rainfall simulations.

植被缓冲带（Vegetative buffer strips）已被证实可有效削减地表径流（surface runoff）中的沉积物、营养盐与除草剂负荷，但现有研究对其降低径流中兽用抗生素负荷的效果尚未得到充分报道。本研究通过开展地表径流模拟实验，探究植被缓冲带的植被状况与宽度对兽用抗生素磺胺二甲嘧啶（sulfamethazine）和林可霉素（lincomycin）的地表径流负荷的削减效果。本次发布的三类数据集具体如下：1. 地表径流模拟实验前，实验植被缓冲带样地土壤的理化性质数据；2. 地表径流模拟实验期间，所有植被缓冲带样地的降雨模拟器运行性能数据与前期土壤含水量数据；3. 降雨模拟实验期间，为测定所有植被缓冲带样地中兽用抗生素残留负荷浓度与悬浮泥沙负荷浓度所采集的地表水水文数据。
