“…17 Because of manure application or wastewater irrigation, 85% of soil samples collected from vegetable fields in the Pearl River Delta of China had maximum concentrations of 406.7 μg/kg of OTC. 18 Besides, in soils beneath piles of manure from livestock farmlands, the concentration of tetracyclines reached 4760 μg/ kg, which was 3.71 times higher than the concentration of tetracyclines from farmlands without manure application. 19 Imidacloprid (IMI) is a typical neonicotinoid insecticide with high selectivity and low toxicity to mammals.…”

Antibiotics can be accidentally introduced into farmland by wastewater irrigation, and the environmental effects are still unclear. In this study, the effects of oxytetracycline on the residue of imidacloprid in soil and radishes were investigated. Besides, the rhizosphere microbiome and radish metabolome were analyzed. It showed that the persistence of imidacloprid in soil was unchanged, but the content of olefin-imidacloprid was increased by oxytetracycline. The residue of imidacloprid in radishes was increased by nearly 1.5 times, and the hazard index of imidacloprid was significantly raised by 1.5−4 times. Oxytetracycline remodeled the rhizosphere microbiome, including Actinobe, Elusimic, and Firmicutes, and influenced the metabolome of radishes. Especially, some amino acid metabolic pathways in radish were downregulated, which might be involved in imidacloprid degradation. It can be assumed that oxytetracycline increased the imidacloprid residue in radish through disturbing the plantrhizosphere microbiome holobiont and, thus, increased the pesticide dietary risk.

“…The average concentration of antibiotics (including four TCs and five QNs) has been detected in winter and summer soils in typical peri-urban areas of eastern China, ranging from 1.50 ± 1.25 to 80.64 ± 111.07, and 0.38 ± 0.51 to 56.38 ± 107.79 μg/kg, respectively [13]. The average concentration of the three TCs (TC, oxytetracycline, and chlortetracycline) in the soil samples of vegetable fields in the South China Pearl River Delta was 78.05 μg/kg [14]. The highest concentration of QNs (ciprofloxacin (CIP), enrofloxacin (ENR), and norfloxacin) in the soil of vegetable planting bases in northern China reached 651.6 μg/kg [15].…”

In this study, we combined ultra-high performance liquid chromatography with tandem mass spectrometry to establish a quick, easy, cheap, effective, rugged, and safe method of detecting 21 target antibiotics in agricultural soil samples.Antibiotics were extracted with mixed solvents consisting of ethylenediaminetetraacetic acid disodium salt dihydrate and phosphoric acid citric acid buffer and acetonitrile which were purified with octadecylsilyl as an adsorbent and anhydrous sodium sulfate as a desiccant. This method was able to effectively extract all of the target antibiotics from agricultural soils, with recovery efficiencies ranging from 55 to 108% and limits of detection between 0.09-0.68 μg/kg. We also validated this new method for selectivity, sensitivity, and reliability of detecting multiple antibiotics in 12 samples. Considering the potential environmental and public health effects of antibiotics in agricultural soils, our new method can help analyze the degree of antibiotic contamination and provide valuable information for soil quality and risk assessment.

“…At present, antibiotic residues have been detected in various environments, including lakes, oceans, soils, sediments, farming wastewater, groundwater, surface water, and even drinking water. The detected concentrations of antibiotics were mostly in the ng or μg range in the environment, but the direct discharge of untreated livestock manure and farm wastewater can even lead to detected concentrations of antibiotics at the mg level in the surrounding environment, which seriously destabilizes the ecological environment [ 5 , 6 , 7 ]. In Korea, florfenicol was detected in the mainstream of the Han River at a concentration of 340 ng/L [ 8 ].…”

Florfenicol is one of the most widely used antibiotics in aquaculture and veterinary clinics because of its low side effects and strong bactericidal effect. A total of 45~60% of florfenicol is not absorbed by the animal body and accumulates in the aquatic environment through a variety of pathways, which affects denitrification. Indoor aquatic microcosm models were constructed and sediment samples were collected at different florfenicol concentrations (0.1, 1, 10, and 100 mg/L) on days 0, 7, 30, and 60 to extract the microbial genome DNA and determine the water properties. qPCR and amplicon sequencing were used to study the dynamic changes in the nirS gene and nirS-type denitrification community structure, diversity, and abundance, respectively. The results showed that high florfenicol stress influenced the sediment’s physicochemical properties, reducing conductivity, alkaline dissolved nitrogen, and organic matter content. In addition, the abundance of nirS, a functional denitrification gene, increased obviously with increased florfenicol concentrations but decreased the diversity of nirS-type denitrification microorganisms. Proteobacteria was the dominant denitrifying phylum in the sediment. Our study provides a scientific basis for the rational use of florfenicol in aquaculture to maintain a healthy and stable microecological environment and also provides a preliminary understanding of the response characteristics of water denitrifying microorganisms to florfenicol exposure.
