“…11,12 Several different analytical methods have been reported for the determination of ENR, including capillary electrophoresis, high-performance liquid chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry. [23][24][25] They have been employed for many purposes, including optical switches, biosensors, biomedical tags, and lasers, with several reviews on their use for electrochemical sensing applications having been reported. These include time-consuming sample preparation, use of toxic organic solvents that generate significant amounts of waste, and the need for high-cost instrumentation.…”

An advanced electrochemical sensor for the detection of enrofloxacin (ENR) based on the use of a modified electrode containing cadmium sulfide (CdS) nanoparticles (NPs) is reported. The CdS NPs were synthesized and characterized and then coated onto the electrode to fabricate a modified electrode that exhibited a lower limit of detection of 9.5 × 10 −8 mol·L −1 . This detection limit compares with a traditional electrode that exhibited a concentration detection range of 1.0 × 10 −2 to 1.0 × 10 −7 mol·L −1 . This modified electrode demonstrated good selectivity, reproducibility, response time (<40 s), lifetime (up to 12 wk), and pH range (3.3-7.2) for the determination of ENR in real samples (eg, pig urine).

“…have shown excellent adsorptive capability despite of the high cost for the carbon particle preparation [24,25]. Meanwhile, pharmaceutical and personal care products (PPCPs) have attracted wide attention in recent studies [26][27][28][29][30][31]. As antibiotics are not easily biodegradable and can cause numerous ecological impacts, residual antibiotics are capable of increasing the antibiotic resistance of bacteria in marine ecosystems, while bioaccumulation and biomagnification in aquatic organisms are another major ecological impact of residue antibiotics [32][33][34].…”

Surface properties of biochars derived from seaweed Sargassum sp. were observed as obvious difference to those from agricultural wastes. In this study, the adsorptive removal of two types of antibiotics, tetracycline (TC) and cefradine (CF), on the biochar were compared and discussed herein. The rod-like tissues of the raw seaweed swelled to be spindle-like at pyrolytic temperature above 400°C. The carbon content was increased from 22.9% of the raw seaweed to 37.2% of the biocharpyrolyzed at 600°C (BC600), while the oxygen content was just increased slightly from 24.7% to 27.8%. The uptake of both TC and CF on the biochar was found to be pH-dependent. The maximum adsorption capacities of TC and CF calculated from the Langmuir model were 128.1 and 61.7 mg/g, respectively, while more CF molecules were adsorbed on biochar at a low adsorbate concentration. Both the Coulombic interaction and π-π electron-donor-acceptor interaction between seaweed biochar and CF/TC molecules played the predominant roles during the adsorption process. The experimental data was well fitted by the pseudo-second-order kinetics model, indicating a possible chemisorption process to some extent. Isotherm result implied that both surface adsorption and partitioning contributed to the uptake of TC and CF onto BC600.

“…Industrial, agricultural, and hospital wastewater include numerous, difficult to remove substances, the neutralization of which requires the most novel, effective, and efficient techniques, which are friendly for the environment. The literature provides examples of new methods used for the removal of different contaminants from the wastewater, including pharmaceuticals and germicides, using processes such as electrochemical treatment with the use of the electro-Fenton (EF) process, electrocoagulation (EC) with aluminum electrodes, electrocoagulation with iron electrodes, flocculation and adsorption, or electrochemical peroxidation (ECP), which is an effective combination of the advanced oxidation process and Fenton (Ahmadzadeh and Dolatabadi 2018b ; Ahmadzadeh et al 2017a ; Yoosefian et al 2017 ; Ahmadzadeh and Dolatabadi 2018c ; Ahmadzadeh et al 2017b ).…”

This article presents the current and important results of bioaerosol studies which allow for the comparison of microbial contamination of air in 11 wastewater treatment plants (WWTPs), which differed in terms of capacity from 350 to 200,000 m3/day. The abundance of mesophilic bacteria, M+ and M− Staphylococcus, Pseudomonas fluorescens, Actinobacteria, coliform and psychrophilic bacteria, and microscopic fungi was determined. Additionally, the air temperature, relative humidity, wind velocity, and direction were also analyzed at each research station. The obtained very numerous results of bioaerosol and climate parameter studies were subjected to statistical analysis. The results regarding the minimum, maximum, and median abundance of the studied bacteria and microscopic fungi at 11 WWTPs and in background studies at control stations were presented in tables. Additionally, basic descriptive statistics for all studied microorganisms at specific seasons were presented. It was established that at the areas of WWTPs, the microscopic fungi were present that the highest concentrations (ranging from 0 to 1,148,530 CFU m−3), followed by psychrophilic bacteria (ranging from 40 to 225,000 CFU m−3) and mesophilic bacteria (ranging from 0 to 195,000 CFU m−3). The novel elaboration of bioaerosol study results based on cluster analysis and determination of a dendrogram allowed to compare the studied WWTPs. The similarity was decided based on the type of studied microorganisms and their dominance and abundance, while no similarities were observed in terms of capacity. In order to investigate the relation between the abundance of bacterial groups as well as microscopic fungi and microclimatic parameters (air temperature and humidity), a calculation of Spearman’s range correlation coefficients was conducted.Electronic supplementary materialThe online version of this article (10.1007/s10661-018-7035-2) contains supplementary material, which is available to authorized users.
