Status of antibiotic residues in milk and dairy products of Iran: a systematic review and meta-analysis
ConclusionsStudies have shown that the prevalence of antibiotic residue in dairy products in Iran is high, so applying an effective strategy and developing the necessary standards in this field to control milk quality is a public health necessity. The findings of this study show that further evaluation of fermented dairy products, especially non-fermented ones such as butter and cream, is needed to prevent adverse health reactions.

Modification of cellulose with TiO2 nanoparticles: Potential solar driven photocatalyst and adsorbent
AbstractIn-situ modification of cellulose fibers with titania nanoparticles (TiO2 NPs) (TiO2 NPs-cellulose) was carried out via the sol –gel process using titania sol and fibers of cellulose. Cellulose fibers were extracted from wheat straw, an agricultural waste material, whereas titania sol was prepared from titanium(IV) acetoximate, [Ti{ONC(CH3)2}4]. The synthesized TiO2 NPs-cellulose composite was characterized by FT-IR, SEM –EDX, and XRD analyses. The obtained results exposed that TiO2 NPs were homogeneously dispersed over the surface of cellulose fibers. A study was conducted to compare the photocatalytic activit...

Cyclic zinc capture and zeolite regeneration using a column method, mass transfer analysis of multi regenerated bed
AbstractTreatment of wastewater and reuse of purified water in an industrial process can provide an alternative source of fresh water as well as reduce pollution load by discharging a lower quantity of wastewater. When adsorption is used for treatment, the regeneration of the used adsorbent may also account for a large portion of the operational cost and cause secondary pollution. This problem may be solved by cyclic repetition of adsorption/regeneration cycles using a column method. In this paper, a total of nine successive cycles of zinc capture and zeolite bed regeneration using a column method have been investigated. T...

Assessment of the environmental performance of sugarcane companies based on waste disposed of on the soil
ConclusionThe theoretical conception used in this study is inspiring for the development of new studies on environmental assessment measurement. The study showed that vinasse is the most problematic waste in environmental terms, a conclusion that is in line with academic studies. Nevertheless, the waste with the greatest potential impact on the environment is filter cake. Despite this, filter cake presented a lower  IEP(i)  than vinasse, given that its negative impact on the basin is smaller. Both wastes contributed 95% of the  IEP Total, which places them among the residues to be managed with greater attention. (Source...

Microplastics as carriers of antibiotic resistance genes and pathogens in municipal solid waste (MSW) landfill leachate and soil: a review
AbstractLandfill leachate contains antibiotic resistance genes (ARGs) and microplastics (MPs), making it an important reservoir. However, little research has been conducted on how ARGs are enriched on MPs and how the presence of MPs affects pathogens and ARGs in leachates and soil. MPs possess the capacity to establish unique bacterial populations and assimilate contaminants from their immediate surroundings, generating a potential environment conducive to the growth of disease-causing microorganisms and antibiotic resistance genes (ARGs), thereby exerting selection pressure. Through a comprehensive analysis of scientific ...

Continuous treatment of highly concentrated tannery wastewater using novel porous composite beads: Central composite design optimization study
AbstractThis present study depicts the successful employment of fixed-bed column for total chromium removal from tannery wastewater in dynamic mode using sodium alginate-powdered marble beads (SA –Marble) as adsorbent. The SA–Marble composite beads prepared were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and Brunauer, Emmett and Teller (BET) method. The adsorption process performance of this bio-sorbent was examined in batches and columns for real effluent (tannery wastewater). After 90 min, th...

Removal of organic micropollutants from water by adsorption on thermo-plasma expanded graphite encapsulated into calcium alginate
AbstractNowadays, public concern is focused on the degradation of water quality. For this reason, the development of innovative technologies for water treatment in view of (micro)pollutant removal is important. Indeed, organic (micro)pollutants, such as pharmaceuticals, herbicides, pesticides and plasticizers at concentration levels of μg L−1 or even ng L−1 are hardly removed during conventional wastewater treatment. In view of this, thermo-plasma expanded graphite, a light-weight innovative material in the form of a powder, was encapsulated into calcium alginate to obtain a granular form useful as filtration and adso...

Potential of some microbial isolates on diesel hydrocarbons removal, bio surfactant production and biofilm formation
AbstractPotential ofArthrobacter citreus B27Pet,Bacillus thuringiensis B48Pet andCandida catnulata to produce biosurfactant using four different carbon sources (naphthalene, hexadecane, diesel and petroleum crude oil) was investigated. Removal of petroleum crude oil from aqueous culture and degradation of diesel were also determined using single and mixed culture of strains. The biofilm existence in single and mixed culture of strains was considered using naphthalene, hexadecane and diesel in culture medium. Cell surface hydrophobicity ofA. citreus was higher than other isolates which also showed maximum surface tension re...

Electrochemical process for petroleum refinery wastewater treatment to produce power and hydrogen using microbial electrolysis cell
AbstractThis research aims to assess the microbial electrolysis cell (MEC) fed with petroleum refinery wastewater (PRW) to produce power density and bio-electrochemical hydrogen. The MEC produces a maximum bio-electricity of 21.4  mA and a power density of 1200123.90 W/m2 with a loading of chemical oxygen demand (COD) of 17000  mg/L. Due to catalyzed oxidation of complex compounds in PRW with a maintained microbial biofilm growth was observed after 90 d of operation of MEC. Results showed that the oxidation of organic substances in PRW enhanced the size in the growth of microbial film which further increased the generati...

Bioaugmentation and phytoremediation wastewater treatment process as a viable alternative for pesticides removal: case of pentachlorophenol
This study focused on the potential for pentachlorophenol removal by a biological process in secondary treated wastewater (STWW). The proposed process is a combined method of phytoremediation using a native plant, Polypogon maritimus and Lemna minor, and bioaugmentation using a fungus. The bioaugmentation process was performed by a fungal isolate capable of removing PCP, isolated from the compost. The identification of the fungus was performed by morphological, biochemical, and molecular methods. A biological treatment system by bioaugmentation and phytoremediation was set up to estimate the capacity of this process to eli...
