The topsoils and atmospheric dust aerosols of the various areas of the city of Moscow were studied. Most of the dust samples contained a considerable number of particles enriched in phosphorus - a sign of contamination by feces. A variety of species, including opportunistic and pathogenic species, were isolated from the topsoil and dust samples and identified using 16S rDNA nucleotide sequences: and . The greatest diversity of pathogens was isolated from spring soil and dust samples immediately after spring snowmelt. Antibiotic resistance of the isolated strains was tested using disks with a wide range of antimicrobial drugs: Amoxicillin, Ampicillin, Meropenem, Pefloxacin, Streptomycin, Ticarcillin+clavulanic acid, Fosfomycin, Ceftibuten, Ciprofloxacin. Resistance was observed in more than 22% of strains. The traffic area had a significant number of antibiotic-resistant strains, clearly indicating a high health risk from soil and dust exposure.

Exposure to ambient particulate matter (PM) with an aerodynamic diameter of <10 μm (PM) is a well-established health hazard. There is increasing evidence that geogenic (Earth-derived) particles can induce adverse biological effects upon inhalation, though there is high variability in particle bioreactivity that is associated with particle source and physicochemical properties. In this study, we investigated physicochemical properties and biological reactivity of volcanic ash from the April 2021 eruption of La Soufrière volcano, St.

To effectively utilize sesbania gum in coal dust control and address the limitations of excessive viscosity and mediocre strength, oxidation treatment was used to improve its fluidity. Polyvinyl alcohol (PVA) and sodium trimetaphosphite (STMP) were used to enhance oxidized sesbania gum OSG, and crosslinking technology was used to improve its mechanical stability. This study developed a novel foam dust suppressant OSG-PVA/SDBS by response surface design, and the optimized dust suppressant material exhibited excellent adhesion and curing properties.

The Arabian/Persian Gulf, a marginal sea of the northern Indian Ocean, has been significantly impacted by human activities, leading to a rise in harmful algal blooms (HABs). This study investigates the summer blooming of an ichthyotoxic phytoflagellate Chattonella marina var. antiqua and associated fish-kill in Kuwaiti waters, connecting the events to a previous dust storm and eutrophication status in the coastal waters of the Northern Arabian Gulf (NAG).

Objective: Different Acanthamoeba species are among the most ubiquitous organisms causing serious diseases in humans including central nervous system (CNS) and eye infections. Contact lenses, lens care solutions and the hospital environments particularly the indoor and outdoor environments of ophthalmology wards where people are present with different types of eye diseases, are the potential sources of human infection. The purpose of the present study was the molecular investigation of free-living amoebae in the used contact lenses, lens care solutions and hospital samples from the ophthalmology wards and operating rooms in a referral hospital in southeastern Iran.
