Global soil antibiotics dataset (dry weight, ng/g)

We revisited previously published databases with records of the occurrence of antibiotics, and collected data on antibiotic concentrations in soils across the globe. Studies and datasets included in these databases were selected according to several criteria: (1) study was not duplicate, and duplicate records were checked and eliminated; (2) only soil-associated samples (within 0–20 cm of soil depth) were retained, and solid manure or waste samples were excluded; (3) soil samples that were not cultured or experimentally treated were included, and only the control soils were considered. However, soils treated by manure fertilization and wastewater irrigation, which corresponded to local land management practices, were not excluded; (4) geospatial information on sampling sites (longitude and latitude) was provided or could be extracted from maps after georeferencing; (5) antibiotic concentrations for each sampling sites were provided (or average values for replicates), and concentrations that were “not detected” or “below detection limit” were assigned zero values; (6) rather than all antibiotics, we mainly focused on environmental concentrations of tetracyclines, quinolones, and sulfonamides antibiotics in soils, as they were widely and frequently detected worldwide 51. In total, these criteria resulted in a final dataset of 659 locations, from which 1,351 soil samples were collected.

本研究回溯了既往已发表的抗生素检出数据库，并收集了全球范围内土壤中抗生素浓度的相关数据。本研究依据以下多项标准筛选纳入上述数据库的研究与数据集：① 研究无重复，且已核查并剔除重复记录；② 仅保留0~20 cm土层深度的土壤相关样本，排除固体粪肥或废弃物样本；③ 纳入未经过培养或实验干预的土壤样本，仅考量对照土壤；但针对符合当地土地管理实践的粪肥施肥及废水灌溉处理的土壤样本，未予排除；④ 采样点位需提供地理空间信息（经度与纬度），或可通过地理配准从地图中提取相关信息；⑤ 需提供每个采样点位的抗生素浓度数据（或重复样本的平均值），对于“未检出”或“低于检测限”的浓度值，赋值为0；⑥ 本研究并非覆盖所有抗生素类别，而是重点关注土壤中四环素类（tetracyclines）、喹诺酮类（quinolones）与磺胺类（sulfonamides）抗生素的环境浓度，因这三类抗生素在全球范围内被广泛且频繁检出[51]。最终，依据上述标准筛选得到包含659个采样点位的最终数据集，共收集1351份土壤样本。
