Evaluation of the interaction between soil and antibiotics

Abstract

The aim of this study was to investigate the occurrence of tetracycline and sulfonamide antibiotics in 13 different soil samples collected from agricultural fields. As well as the antibiotic analysis 18 different physicochemical properties of the soil samples were determined in order to establish a relationship between the recovery rates of antibiotics from the samples and the characteristics of the samples that provide critical information for the reliability of an applied antibiotic analysis method. While the concentrations of tetracyclines were 0.025-0.105 mg kg(-1) sulfonamide antibiotics were not detected in any investigated soil samples. The mean recovery rates of tetracyclines and sulfonamides were 84.57 +/- 14.92% and 65.88 +/- 8.56%, respectively. Although, the organic carbon contents and cation exchange capacities of the soil samples exhibited a great variation the results of multivariate statistical analysis indicated that the metal content of soils was the major factor significantly influenced the recovery rates of the antibiotics. The sulfonamide recovery rates were positively influenced by the calcium and magnesium amounts in the soil samples, whereas tetracycline recovery rates were markedly diminished by increasing the amount of these polyvalent metals.

Effect of composting and soil type on dissipation of veterinary antibiotics in land-applied manures

“…Previous studies demonstrated that antibiotic dissipation in soils is influenced by environmental factors, such as temperature, pH, and soil physicochemical properties, as well as the initial concentrations of antibiotics and their associated matrixes (Otker and Akmehmet-Balcioglu, 2005;Cengiz et al, 2010;Srinivasan and Sarmah, 2014). Chemical properties of the antibiotics can also influence their interactions with soil minerals and organic matter (Otker and Akmehmet-Balcioglu, 2005;Wegst-Uhrich et al, 2014).…”

Yayılı Kirleticilerin Havzalardaki Taşınım Süreçleri: Antibiyotikler, Ağır Metaller ve Besi Maddeleri Üzerine Modelleme Yaklaşımları

“…Antibiyotiklerin suda, atıksuda, toprakta ve çamurda kirletici olarak saptanması ve bu matrikslerde giderimlerini konu alan çalışmalar son yıllarda bilimsel literatürde önem kazanmıştır [19][20][21][22][23][24]. Düşük konsantrasyonlardaki antibiyotiklerin mikroorganizmalarda direnç gelişimine neden olduğu uzun yıllardır bilinmektedir.…”

Treatment of E. coli HB101 and the tetM gene by Fenton’s reagent and ozone in cow manure

“…It has been clearly shown that the number of antibiotic resistance genes increases in soil after application of manure sourced from a farm operation with low or regular use of antibiotics (Schmitt et al, 2006;Cengiz et al, 2010). In addition to already-resistant bacteria, manure can also contain antibiotics that lead to the development of resistance in the environment, and indigenous soil bacteria can create an undesirable reservoir for the spread of antibiotic resistance (Kummerer, 2004).…”
