| Abstract | The potential for developing and spreading antimicrobial resistance in pathogens is the most important health risk associated with the widespread use of antimicrobials in human medication and in the livestock industry. Residual antimicrobials enter the environment through the discharge of contaminated effluent or through land application of contaminated livestock manure. Many studies have investigated the degradation of antimicrobials in water; however, soils and sediments are also an important environmental matrix as they can act as reservoirs for recalcitrant antimicrobials. This research examines the degradation kinetics of antimicrobials in soils and sediments for two processes, biodegradation and sorption. This paper makes three main research contributions. Firstly, we reviewed the literature to discuss the fate and potential adverse impacts of residual antimicrobials in the environment. Secondly, we examine the important processes governing the environmental fate and transport of residual antimicrobials to highlight trends and contributing factors. Lastly, we developed a multi-level experimental design to study the sorption and biodegradation of five priority antimicrobials (lincomycin, monensin, sulfamethazine, tetracycline, and triclosan) in soils and sediments. The results of this experimental study will be used to model the adsorption and biodegradation kinetics of the target antimicrobials. Soil and sediment samples have been collected from three pristine sites in a Southern Ontario watershed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
