Sulfonamides and trimethoprim [PDF]
Sulfonamides and trimethoprim are inexpensive and effective antibacterial drugs that have been used extensively. The use of sulfonamides for systemic use has, however, decreased dramatically for several years, mainly because of resistance development in pathogenic bacteria and allergic side effects. Also the clinical efficiency of trimethoprim has been

Ecofriendly Synthesis in Aqueous Medium: An Expeditious Approach to New N,N-Diethyl Amide Bearing Benzenemethanesulfonamides [PDF]
An highly expeditious synthetic approach for the synthesis of benzenemethanesulfonamides (1a-k) and their new corresponding N,N-diethyl substituted amido moieties (2a-k) has been achieved in aqueous medium at room tem-perature. The reaction condition was

Enzymatic Transformation and Bonding of Sulfonamide Antibiotics to Model Humic Substances
Sulfonamides are consumed as pharmaceutical antibiotics and reach agricultural soils with excreta used as fertilizer. Subsequently, nonextractable residues rapidly form in soil, which has been researched in a couple of studies.

Antibiotic residues and antibiotic-resistant bacteria in pig slurry used to fertilize agricultural fields [PDF]
Pig manure may contain antibiotic residues, antibiotic-resistant bacteria or pathogens, which may reach the environment upon fertilization. During this study, 69 antibiotic residues belonging to 12 classes were quantified in 89 pig slurry samples.

Synergistic toxicity of some sulfonamide mixtures on Daphnia magna [PDF]
In livestock farming, sulfonamides (SAs) are used prophylactically and simultaneously in large numbers of animals. Therefore, traces of these compounds, alone or in combination, have been repeatedly detected in the environment.
