A Critique of Studies on The Combined Effect of Dust Storms and Meteorological elements on Cardiovascular, Cerebrovascular, and Respiratory Diseases
Brief policy The studies reviewed in this section are from PubMed, ISI, Science Direct, Google Scholar, and Scopus databases using the following keywords: dust storm, meteorological elements, temperature, heat wave, cold wave, relative humidity, wind blow, atmospheric pressure, cardiovascular diseases, respiratory diseases, cerebrovascular diseases, myocardial infarction (MI), stroke (CVA), l...
متن کاملEfficiency of filtering materials used in respiratory protective devices against nanoparticles.
The basic aim of this research was to establish the efficiency of filtering materials widely used in respiratory protection devices with particular interest in their porosity, degree of electric and changeable process parameters, such as the flow rate of the test nanoaerosol and the size range of nanoparticles. Tests were carried out with an NaCl solid aerosol of 3.2 × 105 particles/cm3 for the...
متن کاملProtective effect of respiratory devices in farmers with occupational asthma.
To the authors' knowledge there have been no previous reports on the protection afforded by powered filtering respirators in farmers with occupational asthma attributed to the inhalation of organic dust. In order to investigate this question, 26 farmers with occupational asthma were challenged with an exposure to work-related dusts for up to 60 min. This resulted in highly significant increases...
متن کاملDeposition and resuspension of selected aerosols particles on electrically charged filter materials for respiratory protective devices.
The primary aim of the study was to analyse the non-steady state of filtration for selected electrostatic filter materials designed for use in respiratory protective devices. The obtained results showed that the filtration process in electrostatic filters was dependent in the main on the following factors: type of the filter material, electrostatic field strength of the material, and the charge...
متن کاملEffect of respiratory protective devices on development of antibody and occupational asthma to an acid anhydride.
STUDY OBJECTIVES To determine whether the use of respiratory protective equipment would reduce the incidence of occupational asthma due to exposure to hexahydrophthalic anhydride (HHPA). DESIGN Prospective cohort study. SETTING A facility that makes an epoxy resin product requiring HHPA for its manufacture. PARTICIPANTS Sixty-six individuals newly hired at a facility that makes an epoxy r...
