摘要

融雪期间磺胺甲恶唑（SMX）在草原农业生态系统中的命运尚不清楚。本研究旨在首次估计有施肥历史的田地融雪中SMX的浓度和负荷。整个融雪期SMX的平均浓度为0.0345±0.066µg/L。SMX累积负荷为3.81±3.4µg/L，范围为1.03–12.8µg/L。浓度和负荷均不受施用粪肥方法的影响（即表面施用与亚表面施用）。

The fate of dissolved sulfamethoxazole during spring-thaw snowmelt in a field with a history of manure application

The fate of sulfamethoxazole (SMX) in Prairie agroecosystems during snowmelt is not well understood. This study aims to provide the first estimates of concentrations and loads of SMX in snowmelt in a field with a history of manure application. The mean concentration of SMX throughout the snowmelt period was 0.0345 ± 0.066 µg/L. The SMX cumulative load was 3.81 ± 3.4 µg/L with a range of 1.03 – 12.8 µg/L. Both the concentration and load were not influenced by the method of manure application (i.e., surface applied versus sub-surface applied).

期刊介绍： The Canadian Journal of Soil Science is an international peer-reviewed journal published in cooperation with the Canadian Society of Soil Science. The journal publishes original research on the use, management, structure and development of soils and draws from the disciplines of soil science, agrometeorology, ecology, agricultural engineering, environmental science, hydrology, forestry, geology, geography and climatology. Research is published in a number of topic sections including: agrometeorology; ecology, biological processes and plant interactions; composition and chemical processes; physical processes and interfaces; genesis, landscape processes and relationships; contamination and environmental stewardship; and management for agricultural, forestry and urban uses.
