Abstract This article was aimed at investigating the removal of metronidazole (MNZ) from aquatic solutions by modified activated carbon (MAC) with amine groups. The effect various parameters on adsorption rate such as initial pH, adsorbent dose and concentration MNZ contact time were scrutinized. MAC characterized Fourier transform infrared spectroscopy Brunauer–Emmett–Teller techniques. obtained results illustrated that under optimum conditions (pH = 3, 50 min, 5 mg/L 0.5 g/L), maximum...

In addition to their advantages as promising methods for wastewater treatment, CWs exhibit poor performance in terms of N and P removal efficiency the effluent treatment plants. By focusing on this issue, we designed integrated with a biochar-doped activated carbon cloth (ACC) electrode alum sludge from water plants substrate achieve concomitant organic matter nutrient efficiency. Compared use one layer (CWs-C3) ACC electrodes inserted two layers, which uses sludge, significant improvement...

Pharmaceutical compounds which enter the environment are classified as emerging pollutants. Among different drug compounds, anti-cancer drugs like methotrexate of more concern due to their mutagenic, carcinogenic, and genotoxic properties. Therefore, main objective this study was use catalytic ozonation processes (COPs) novel advanced oxidation degrade from aqueous solutions. The calcination method used obtain a nitrate magnesium oxide nano-catalyst. variables considering effect single...

Nitrate is a groundwater pollutant which in higher concentrations limits, leads to health hazard such as Methemoglobinemia and formation of nitrosamine compounds. In this research, the nitrate nitrite all water resources villages Songor plain were determined relationship between these values with table zonation concentration investigated GIS environment. study, 37 samples Sonqor taken in, high (March 2016) low (October 2017) periods. Water levels then by spectrophotometry results compared...

This work presents a novel, strong and efficient adsorbent (CS@TDI@EDTA@γ-AlO(OH)) prepared through the green process using three components, chitosan, BNPs EDTA amide ester bridges. An eco-friendly easy approach was used for preparation of this novel adsorbent, low cost, access to materials, simplicity method are some interesting advantages work. Also, as an remove diazinon organophosphate poison tetracycline antibiotic from aqueous solutions. In order confirm structure,...

Recent studies have shown that the rate of needlestick and sharps injuries (NSIs) is unacceptably high in Iranian hospitals. The aim present study was to use a systematic approach predict reduce these injuries.

This study investigates the kinetic model of chemical oxygen demand (COD) removal from olive oil mill synthetic wastewater through electrocoagulation using stainless steel and aluminum as a cathode anode electrodes, respectively.The one-factor method was used to evaluate interactions between operational parameters that affect COD removal.A reactor with volume 250 mL utilized perform process.The optimal conditions 99% were found be current density 12.5 mA cm -2 , 400 mg L -1 NaCl supporting...

The human body is primarily water and healthy drinking vital to life. Today, the bottled-water industry has been widely developed in most countries more than 150 several brands of bottled are produced Iran. Considering increasing consumption its potential for contamination with harmful chemical microbial agents such as nitrate, aim this study was assess nitrate concentration also quality a number Torbat-e Heydarieh city 2017. In present descriptive-analytical research, random sampling (80...

Nurses, as the largest forces in health system, are always challenged with various work responsibilities such long working hours, lack of manpower and death patients. This study aimed at providing a model relationship between workload physical mental health, sleep disorders, individual family problems by mediation role job stress. The present is cross-sectional that was conducted on 300 nurses specialty sub-specialty hospital Tehran. For this reason, questionnaires including demographic,...

The efficacy of electrostimulation on bacterial lipase activity and COD removal was studied using a laboratory bioelectrochemical system.

According to studies, high concentration of fluoride in drinking water has adverse health effects such as dental and skeletal fluorosis. This data analyzes the concentrations risks 30 samples collected from 11 villages Khash city, Sistan Baluchistan province Iran. Fluoride was measured using SPADNS method according standard for examination wastewater. Data indicated that average 0.731 mg L−1. The mean estimated daily intake (EDI) values different groups infants, children, teenagers adults...

A quantitative model on exposure to pathogenic viruses in air of recreational area and their corresponding health effects is necessary provide mitigation actions content emergency response plans (ERP). Here, the risk associated with two concern: Rotavirus (RoV) Norovirus (NoV) water spray park were estimated using a microbial assessment (QMRA) model. To this end, real-time Reverse Transcriptase polymerase chain reaction (real-time RT-PCR) was employed measure concentration levels RoV NoV...

The main of this data was determine the concentrations and health risks fluoride in 66 drinking water samples collected from villages Iranshahr city, Sistan Baluchestan Province Iran. Fluoride concentration measured by standard SPADNS method. Data indicated that ranged 0.25 to 1.72 mg L-1 average 0.27 L-1. mean estimated daily intake (EDI) values for different groups infants, children, teenagers adults were 0.0021, 0.0151, 0.0107 0.0086 mg/kg, respectively. Also, risk assessment hazard...

The aim of this research is to achieve an efficient and cheap methods remove H2S from the factories emissions. Four serial cylinders are designed, 40 cm in height 15 diameter each. They filled with bivalve seashells 63% porosity which contains Thiobacillus thioparus bacteria maximum 27.5 cm. By mixing phosphoric acid sodium sulfide, gas released its concentration measured as mg m(-3) before injecting into cylinders. A permanent measuring instrument equipped control coming out In order...

Hospital wastewater is mainly a source of pharmaceutical compounds entering water resources. The presence the residual compounds, due to inability conventional treatment processes, will lead introduction these into environment and therefore have its own environmental health effects. In present study, degradation mineralisation cyclophosphamide from aqueous solution was investigated using UV/Persulphate process effect variables such as pH, persulphate concentration, reaction time, rate were...

The aim of this study is to determine the Aluminum concentration in groundwater resources Sistan and Baluchestan province, Iran. See data article.
