“…The complex and electrostatic interactions with metal ions could increase the stability of antibiotics, thus increasing their persistence in soil. Positive effects of Zn and Cu on the adsorption of antibiotics in soil have been reported in previous studies (Tamtam et al 2011;Zhang et al 2009). However, there is no information regarding the effect of Cd, Pb, and V on the adsorption of antibiotics in soil to date.…”

“…The different concentrations of antibiotics in urban soil may be affected by soil characteristics such as pH, TOC, and metal content since these parameters were reported to affect the adsorption of antibiotics in solid environmental matrices (Tolls 2001;Vasudevan et al 2009;Zhang et al 2009). …”

“…It has been reported that most antibiotics can form complexes with metal ions (Tamtam et al 2011;Tolls 2001;Zhang et al 2009). Previous studies have reported that some antibiotics, such as QNs and tetracyclines, may undergo complex formation at aluminum and iron hydroxide surface (Tolls 2001).…”

The recycling of reclaimed wastewater for irrigation and road cleaning is an important strategy to minimize water scarcity in megacities. However, little is known regarding the potential accumulation of antibiotics contained in reclaimed wastewater in urban soil. We investigated the occurrence and distribution of eight quinolones (QNs), nine sulfonamides (SAs), and five macrolides (MLs) antibiotics in urban surface soil in Beijing and Shanghai, China. QNs, especially norfloxacin (NOR), ofloxacin (OFL), and ciprofloxacin (CIP) were the predominant antibiotics in urban surface soil, and NOR revealed the highest average concentration of 94.6 μg kg −1 . The antibiotic concentrations in urban soil in our study were higher than those detected in agricultural soils after long-term wastewater irrigation and manure fertilization. The concentrations of antibiotics in Shanghai urban soil showed a significant negative correlation with soil pH and a positive correlation with total organic carbon (TOC), reflecting the effect of speciation and soil organic matter content on sorption and retention. In addition, antibiotic concentrations in the urban soil were positively correlated with heavy metal contents, likely due to their coexistence in reclaimed wastewater and the promoting effect of metals on the sorption of antibiotics. In several soil samples, NOR, OFL, CIP, enrofloxacin (ENR), and fleroxacin (FLE) showed higher concentrations than the trigger value of 100 μg kg −1 in soil, indicating a potential risk for the environment.

“…But the present study showed no effect on soil bacterial numbers in norfloxacin-treated soils when comparing with the control without addition of norfloxacin. This is probably due to the strong adsorption of this antibiotic onto soil components, [21] which can significantly reduce its bioavailability and effects on soil microbial community. The present study found little effect of norfloxacin on soil respiration in the soil, but significant inhibiting effect on soil nitrification at concentrations >100 mg/kg was found.…”

This paper investigated the degradation kinetics of norfloxacin in a soil, and its effects on soil respiration and nitrogen transformation under different conditions. Compared to the sterile control, the degradation rates of norfloxacin in the non-sterile soil were greatly enhanced, suggesting that microorganisms played a major role in the degradation. Accelerated degradation for norfloxacin in the soil was observed with decreasing concentrations (30 mg/kg to 5 mg/kg) with its half-life decreasing from 62 days to 31 days. Amending swine manure into the soil and increasing the soil moisture level enhanced the biological degradation of norfloxacin. No obvious inhibition of norfloxacin on soil respiration was observed in the soil, while only slight effect on nitrogen transformation was found. The results suggested that norfloxacin at the reported environmental concentrations (<100 mg/kg) would have little effect on microbial activity and functions in the soils.

“…The levels of NOR showed significantly positive relationships with the heavy metals (e.g., As, Cd, Co, Cu, Mo, and Pb) (p < 0.05), respectively. This phenomenon associated with the concurrent presences of NOR and heavy metals may be attributed to the common mechanism of electrostatic adsorption in the sediments [59,60]. In comparison, no significant relationships were found between the heavy metals and other antibiotics.…”

Antibiotic pollutions in the aquatic environment have attracted widespread attention due to their ubiquitous distribution and antibacterial properties. The occurrence, distribution, and ecological risk assessment of 17 common antibiotics in this study were preformed in a vital drinking water source represented as a river-reservoir system in South China. In general, 15 antibiotics were detected at least once in the watershed, with the total concentrations of antibiotics in the water samples ranging from 193.6 to 863.3 ng/L and 115.1 to 278.2 µg/kg in the sediment samples. For the water samples, higher rain runoff may contribute to the levels of total concentration in the river system, while perennial anthropic activity associated with the usage pattern of antibiotics may be an important factor determining similar sources and release mechanisms of antibiotics in the riparian environment. Meanwhile, the reservoir system could act as a stable reactor to influence the level and composition of antibiotics exported from the river system. For the sediment samples, hydrological factor in the reservoir may influence the antibiotic distributions along with seasonal variation. Ecological risk assessment revealed that tetracycline and ciprofloxacin could pose high risks in the aquatic environment. Taken together, further investigations should be performed to elaborate the environmental behaviors of antibiotics in the river-reservoir system, especially in drinking water sources.
