“…Sulfonamides have a long half-life, and their widespread use in human and veterinary medicine affects the concentration and accumulation of these antibiotics in the environment. The continuous presence of subclinical concentrations of sulfonamides in the environment can decrease the significance of these drugs as selective factors that induce antibiotic resistance [ 108 ]. As a result, antibiotic resistance can be promoted mainly by HMs.…”

The spread of antibiotic resistance is closely related with selective pressure in the environment. Wastewater from industrialized regions is characterized by higher concentrations of these pollutants than sewage from less industrialized areas. The aim of this study was to compare the concentrations of contaminants such as antibiotics and heavy metals (HMs), and to evaluate their impact on the spread of genes encoding resistance to antimicrobial drugs in samples of wastewater, sewage sludge and river water in two regions with different levels of industrialization. The factors exerting selective pressure, which significantly contributed to the occurrence of the examined antibiotic resistance genes (ARGs), were identified. The concentrations of selected gene copy numbers conferring resistance to four groups of antibiotics as well as class 1 and 2 integron-integrase genes were determined in the analyzed samples. The concentrations of six HMs and antibiotics corresponding to genes mediated resistance from 3 classes were determined. Based on network analysis, only some of the analyzed antibiotics correlated with ARGs, while HM levels were correlated with ARG concentrations, which can confirm the important role of HMs in promoting drug resistance. The samples from a wastewater treatment plant (WWTP) located an industrialized region were characterized by higher HM contamination and a higher number of significant correlations between the analyzed variables than the samples collected from a WWTP located in a less industrialized region. These results indicated that treated wastewater released into the natural environment can pose a continuous threat to human health by transferring ARGs, antibiotics and HMs to the environment. These findings shed light on the impact of industrialization on antibiotic resistance dissemination.

Antibiotics are widely used in aquaculture. Intensive farming drives indiscriminate use of antibiotics, which results in residues of antibiotics in cultured aquatic products and bacterial resistance. This perspective attempts to present a brief update on usage, regulations, residues, and potential human health risk of antibiotics used in aquaculture. Through the comprehensive literature review, we provide a view that the safety of aquatic products still requires further attention and more rigorous risk assessment. Finally, we make a few suggestions for future research directions: reduce the use of antibiotics to bring down the speed of resistance development and monitor resistant pathogens and genes, strictly manage the environmental sanitation of aquaculture and pay attention to the quality of water bodies introduced into aquaculture, seek international cooperation to establish an information bank of antibiotic residues and antibiotic-resistant genes, and set up a quantitative model to assess the risk of antibiotic resistance associated with the antibiotic residues.

“…A number of papers con cern the development of hydrodynamic models as for the slur ry migration over a conic surface. Basically, the papers deter mine stationary parameters of the migration process [6,7], analyze effect of different factors on the hydraulic mixture nonuniform motion [8] as well as surface soil reclamation [9]. However, the papers pay insufficient attention to dynamic characteristics of the process and ignore roughness parameters of hard border of the stream.…”

SToNe wAShouT AND miGrATioN wiThiN AN exTrAcTioN chAmber Purpose. To substantiate parameters of zeolitesmectite puffstone deposit hydromining method while analyzing dependences between physicotechnological indices of hydromining equipment and rock mass characteristics, which will help optimize the extraction technique. methodology. Complex research approach (i.e. field observations, laboratory tests, and bench testing) is the methodological basis to solve the problem. The approach involves system analysis, physical modeling of hydrodynamic processes, and outcome analysis using MаtLаb mathematical software package. findings. Dependences of zeolitesmectite puffstone failure upon a mouthpiece diameter, water pressure, washout radius, and gravity streaming hydraulic transportation within an extraction chamber have been determined. Effect of kinetic energy of a falling slurry stream on the decrease in the specific power consumption in the process of rock transportation over an extraction chamber floor has been identified. Power consumption dependence upon hydraulic monitor dimensions and working agent pressure is of quadratic nature: the increased pressure of a working agent in front of a mouthpiece, power consumption of the washout increases, and specific water consumption drops. originality. For the first time, an approach to describe zeolitesmectite puffstone failure taking into consideration hydrody namic puffstone washout, hydraulic mixture migration within an extraction chamber, and transportation of the mineral has been applied. Relying upon power consumption to washout hydraulic mixture and transport it within a washout chamber, both linear nature and directlyproportional dependence of transport capacity upon hydraulic monitor loss and chamber floor slope has been determined. Power consumption dependence has been defined for different types of mouthpieces and working agent pressure in order to avoid cuts and layerbylayer washout of a mineral. Practical value. The obtained results can be applied to improve dominating parameters influencing the hydrodynamic process for zeolitesmectite puffstone washout. For the purpose, rational efficiency of puffstone failure has been identified as well as ro tational angle of a lateral mouthpiece of a jet head at 15-20 m height in terms of layerbylayer washout with rock migration over a distance being equal to a half of the washout diameter. Real conditions (for zeolitesmectite puffstones) have been determined under which minor jet velocity variation from the determined parameters results in a cut or in a fall of the washout chamber.
