“… Kümmerer (2009) also reported that antibiotics seemed unlikely to affect fish in aquatic environment. The similar results were also gained by a recent literature ( Xie et al., 2019 ). But, considering a long-term bioaccumulation and combined toxicity of multiple antibiotics for invertebrate or fish, the risks of antibiotic pollution cannot be ignored.…”

“…As reported, there are 4 levels of ecological risks, according to the RQ values: RQ ≥ 1 (high risk), 0.1 ≤ RQ < 1 (median risk); 0.1 ≤ RQ < 0.01 (low risk) and RQ ≤ 0.01 (no risk) ( Wei et al., 2019 ). In this study, the RQ values were calculated for effluent water and soil fertilizered by manure, according to the methods in the previous publications ( Yang et al., 2016 ; Xie et al., 2019 ; Xu et al., 2013 ).…”

Antibiotic pollution from family animal farms is often neglected, but the waste from these farms usually caused more harm to the surroundings because arbitrary discharge without effective disposal. The pollution status and ecological risks of 45 veterinary antibiotics on 33 family animal farms in Dali city, Erhai Lake basin of China, were firstly delivered. The results showed that antibiotic contamination was prevalent in different environmental mediums (feed, manure, wastewater and soil) on these family farms. Manure had highest antibiotic levels among all the environmental mediums. Tetracyclines (TCs) usually had higher concentrations (ND-404.95 mg/kg) than the other classes, among which chlorotetracycline (CTC) was the dominant type. Among different animal species, target 13 pig farms had the highest antibiotic concentrations, the most total types and unique types of antibiotics, which were followed by target 11 chicken farms then target 9 cattle farms. The antibiotic densities of animal waste were calculated by per animal, which showed that pig waste presented high density; and family chicken farms were characterized by quinolone antibiotics (QAs) and macrolide antibiotics (MAs) pollution. For the antibiotic ecological risks in effluent water, oxytetracycline (OTC), CTC, ofloxacin (OFL), enrofloxacin (ENR), ciprofloxacin (CIP) and sulfamethoxazole (SMX2) exhibited much more toxic effects on algae. OTC and doxycycline (DXC) posed high risk for invertebrate; while no antibiotic caused high ecological risk for fish. Some antibiotics were quantitatively detected in the soil but no antibiotic posed obvious ecological risks on soils. However, the interaction of synergistic or antagonistic effects between different antibiotics should be brought to the forefront. This study gave some information of antibiotic pollution on family livestock farms, which indicated that animal waste from family farms was indeed an important pollution source of antibiotics for the environment.

“…Mariculture and coastal aquaculture activities can lead to pollution by micropollutants (e.g., antibiotics) in coastal seawater, which host the highest biodiversity in the world. Thus, it is important to investigate bioremediation solutions for organic micropollutants in coastal waters [20]. The study of Benotti and Brownawell (2009) indicated that the microbial degradation of pharmaceuticals, such as sulfamethoxazole and trimethoprim, in and near a wastewater-polluted estuarine and coastal seawater and sediments, is much slower than the degradation of biomolecules, such as glucose and amino acids [13].…”

To cope with bacterial infections, broad-spectrum antibiotics such as sulfonamides have been largely used for intensive coastal aquaculture. Sulfonamides are stable and difficult to remove by conventional wastewater treatment. Environmental pollution will occur if sulfonamide-containing aquaculture wastewater is discharged into rivers and oceans. In this study, high salinity-tolerant bacterial strains A12 and L with sulfamethoxazole (SMX)-degrading ability from milkfish (Chanos chanos) culture pond sediments with SMX were isolated, identified, and characterized. The degradation of SMX and the changes in the bacterial community in milkfish culture pond sediments were assessed. Phylogenetic analysis using 16S rRNA gene sequences suggested that bacterial strain A12 was very close (99% sequence identity) to Vibrio sp., and bacterial strain L was very close (99% sequence identity) to Pseudomonas sp. Aerobic and anaerobic batch and continuous SMX addition experiments indicated that bacterial strains A12 and L could enhance SMX degradation in milkfish culture pond sediments. Different microbial community compositions under aerobic and anaerobic conditions exhibited different SMX-degrading abilities. The results of this study suggest that bacterial strains A12 and L provide a solution for treatment of wastewater and sediment from SMX-contaminated high salinity milkfish culture ponds.

“…Water pollution by pesticides is a widespread problem. Several pesticides haven been detected in surface and groundwater, as it has been described by a great number of research studies (Bortleson and Davis, 1997;Aydin et al, 2018;Xie et al, 2019). Moreover, human health is significantly affected by this kind of pollution, producing, among other problems, fertility diseases (Cano-Sancho et al, 2019).…”

Electro Fenton removal of clopyralid in soil washing effluents

et al. 2019

The removal of a commercial herbicide, based on clopyralid, by means of Electro-Fenton (EF) was studied using a soil washing effluent obtained using synthetic ground water as washing fluid. From the results, it was observed that the degradation and mineralization yields of clopyralid were high, even without the addition of supporting electrolyte. The groundwater could be then used as a sustainable supporting electrolyte. The influence of the minerals constituents, the current and the ferrous ions regeneration was evaluated. The highest hydrogen peroxide production was achieved working at 200 mA but regeneration of ferrous ions was not efficient at this current. Iodide ions were one of the main responsible in the EF efficiency decrease due to their reaction with the produced hydrogen peroxide. Electrochemical study proved that clopyralid was not electroactive and that its degradation was mainly due to radical oxidation. Long duration electrolysis carried out at 200 mA in groundwater provided an improvement of the solution biodegradability after 480 min that can be linked to a significant increase in the carboxylic acids production. These results support the feasibility of applying an EF process in order to carry out a subsequent biological mineralization.
