Insight into the role of dissolved organic matter in sorption of sulfapyridine by semiarid soils

Environmental Science & Technology
Hai HahamBenny Chefetz


Sorption-desorption behavior of sulfapyridine was studied with three distinct soil types low in organic carbon with or without the introduction of exogenous dissolved organic matter (DOM). Experiments with bulk soils yielded sorption coefficients equivalent to those obtained with soils richer in organic matter, indicating an important sorptive role for soil mineral matrices. Cointroduction of sulfapyridine with DOM significantly reduced sulfapyridine sorption. However, decreasing solution pH from ~9 to ~6 limited the effect of DOM and revealed the effect of ionic speciation of sulfapyridine on the sorption potential. Sulfapyridine sorption to soils precoated with DOM exhibited contrasting trends. Two of the coated soils exhibited decreased sorption of sulfapyridine probably due to blockage of sorption sites by DOM. Conversely, the third soil demonstrated cumulative adsorption of sulfapyridine. Precoating also enhanced sulfapyridine desorption, suggesting that sorption of sulfapyridine to mineral surfaces involves stronger chemisorptive binding as compared with interactions with sorbed DOM. The capacity of soil to sorb DOM as well as the chemical fractionation of DOM during sorption were found to significantly affect binding of ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
