Prevalence of MRSA as an Infectious Agent in Sanitary Swimming Pools and Jacuzzis
ConclusionThe number of reported sanitary water is increasing, and this study's results are useful examples of these findings. Therefore, a lack of careful and regular monitoring of swimming pools and Jacuzzis can lead to MSRA prevalence and outbreak sources. (Source: Journal of Environmental Health Science and Engineering)

Association between atmospheric particulate matter and emergency room visits for cerebrovascular disease in Beijing, China
ConclusionThis study showed that the effects of PM pollution on cerebrovascular disease were different among different gender and age groups, and aged 61 –75 years were mostly sensitive to particulate matters. The effects of PM2.5 on cerebrovascular disease were stronger than those of PM10. Our results can provide scientific evidence for the local government to take effective measures to improve air quality and the health of residents.

Simultaneous biodegradation of BTX by isolated degrading bacterial strains in a newly designed modulated bio-scrubber assisted to airlift parallel bioreactors
AbstractA new approach in this present study, isolated bacteria from refinery sludge were used in a laboratory-scale bio-scrubber, connecting with two parallel airlift bioreactors to eliminate harmful and toxic fumes of BTX. One of the main features of this bio-scrubber is using porous mineral pumice fillers (Lava Rock) inside poly-urethane foam (PUF)  module tower, connecting with agitator bio-phasic continuously stirred tank bio-reactor (CSTbR) to increase retention time and contact surface. The bio-scrubber and airlift plug flow bio-reactor (PFbR) were used in parallel with cooling flow to be more efficient in preserv...

Mineralization of pyrene (polycyclic aromatic hydrocarbon) in clay soil supplemented with animal organic carbon source
AbstractBiostimulation of polycyclic aromatic hydrocarbons (PAHs) is a major concern in the environment due to their toxic nature and ubiquitous occurrence. The study aimed to determine the best animal supplement of organic carbon source (cow dung, goat dung, pig dung and poultry (fowl droppings) and indigenous microbes capable of mineralizing pyrene in clay soil. Clay soil sample was collected from the top surface soil (0 – 15 cm) in Ikpoba River and upper Lawani river bank, both in Benin City with the aid of stainless steel trowel and gloved hands and stored in a polyethylene bag. The isolation and identification proc...

A city-level analysis of PM2.5 pollution, climate and COVID-19 early spread in Spain
ConclusionsA longer period applying human activity restrictions is necessary in order to achieve significant reductions of PM2.5 levels in all the analyzed cities. No effect of PM2.5 pollution or weather on COVID-19 incidence was found for these pollutant levels and period of time.Graphical abstract (Source: Journal of Environmental Health Science and Engineering)

Influence of Fe3O4 and Carbon Black on the Enhanced Electromagnetic Interference (EMI) Shielding Effectiveness in the  Epoxy Resin Matrix
AbstractThe present study aims to investigate the shielding properties of the electromagnetic interference of polymer nanocomposites with different weight percentages of magnetite nanoparticles and cost-effective carbon black nanoparticle  (CBN) on different thicknesses. X‐ray diffraction test, Raman spectroscopy, the scanning electron microscopy, and the transmission electron microscope analysis were used for investigating the crystallographic structure, morphology and microstructure of the material. The nanocomposites were successfully prepared using a simple mixing and casting. Their shielding efficiency was meas...

Heavy metal contaminated soil, water, and vegetables in northeastern Iran: potential health risk factors
ConclusionWhile it seems that consuming vegetables has no acute health risk related to heavy metals, long-term and regular ingestion of the vegetables are likely to make cancer risk. Besides, due to the high concentration of Pb in soil and vegetables, regular and integrated assessment of heavy metals in soil, water, and food is necessary.

Distribution and human health hazard appraisal with special reference to chromium in soils from Peenya industrial area, Bengaluru City, South India
ConclusionsThe study area is polluted, mainly with Chromium, whereas environmental risk is limited to a small part of it. This study can be used as a reference point to develop future long-term risk assessment plans on the probable movement of heavy metals in urban soils to human beings.

Microbial activity and community level physiological profiles (CLPP) of soil under the cultivation of spring rape with the Roundup 360 SL herbicide
ConclusionCultivation of specific plant varieties that reduce the negative effect of herbicides used in agriculture may be one of the methods to prevent soil degradation. In our research, Belinda turned out to be a cultivar, under the cultivation of which an increase in the activity of microorganisms was recorded most frequently compared to soil not sown with rapeseed.

Drying of virus-containing particles: modelling effects of droplet origin and composition
ConclusionDifferences in solute composition between airway surfaces and saliva are predicted to lead to different drying behaviour of droplets emitted by breathing, speech and coughing. These differences may influence the inactivation of viruses. (Source: Journal of Environmental Health Science and Engineering)

Conversion of biomass to N, S co-doped porous graphene as an adsorbent for mercury vapor removal: optimization and DFT study
This study is devoted to optimization synthesis conditions of the N, S co-doped porous graphene via a single step thermal chemical activation process from agricultural wastes such as cabbage waste. To this end, the response surface method (RSM) was considered, and the synthesis parameters were varied in specific ranges. By doing so, the optimum conditions in terms of the best performance in mercury removal was determined which was characterized by TEM, SEM, BET, XRD, XPS, and FTIR techniques. The chosen key process parameters were Activation agent to carbon precursor ratio (A: KOH/C), Reaction time (B: Time), Activation te...

An experimental investigation on the oxidative desulfurization of a mineral lubricant base oil
AbstractIn the present study, the oxidative desulfurization (ODS) of Sn 650 base oil with total sulfur content of 10,000 ppmw has been investigated experimentally. The response surface methodology (RSM) considering Box-Behnken design (BBD) was applied to examine the impacts of the oxidation temperature (30 –70˚C), hydrogen peroxide to sulfur molar ratio (2–8), and formic acid to sulfur molar ratio (20–60) on the sulfur removal. In the next step, the appropriate values of the independent variables such as stirrer speed (750–1250 rpm), reaction time (60–180 min), and the number of extractio n stages (1–4) were...
