OBJECTIVES Previous studies have implicated air pollution in increased mortality and morbidity, especially in the elderly population and children. More recently, associations with mortality in infants and with some reproductive outcomes have also been reported. The aim of this study is to explore the association between exposure to outdoor air pollution during pregnancy and birth weight. DESI...

In order to address the role that the ambient air pollution mix, comprised of gaseous pollutants and various physical and chemical measures of particulate matter, plays in exacerbating cardiorespiratory disease, daily measures of fine and coarse particulate mass, aerosol chemistry (sulfates and acidity), and gaseous pollution (ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide) were c...

BACKGROUND Acute exposure to air pollution has been linked to myocardial infarction, but its effect on heart failure is uncertain. We did a systematic review and meta-analysis to assess the association between air pollution and acute decompensated heart failure including hospitalisation and heart failure mortality. METHODS Five databases were searched for studies investigating the association...

Communication of the complex relationship between air pollutant exposure and ill health is essential to an air pollution information system. We propose a novel air pollution index (API) system based on the relative risk of the well-established increased daily mortality associated with short-term exposure to common air pollutants: particulate matter (PM10, PM2.5), sulphur dioxide, ozone, nitroge...

In order to maintain the RENAR (Romanian Accreditation Association) accreditation, each accredited laboratory must periodically participate in interlaboratory testing programs carried out with specialized providers or similar laboratories. December 2021, an comparison field of environmental protection was organized by INCD ISEMEX PETROȘANI. The current paper examines similarity results two auto...

The reductive functionalization of carbon dioxide into high value organics was accomplished via the coupling with carbon monoxide and ethylene/propylene at a zerovalent nickel species bearing the 2-((di-t-butylphosphino)methyl)pyridine ligand (PN). An initial oxidative coupling between carbon dioxide, olefin, and (PN)Ni(1,5-cyclooctadiene) afforded five-membered nickelacycle lactone species, wh...

Falling back past few years rapid progress in Air pollution has become a life-threatening concern many nations throughout the world due to human activity, industrialisation, and urbanisation.. As result of these activities, sulphur oxides, carbon dioxide (CO2), nitrogen monoxide (CO), chlorofluorocarbons (CFC), lead, mercury, other pollutants be emitted into atmosphere. Simultaneously, estimati...

the physical adsorption of hydrogen sulfide and carbon dioxide gases on the zigzag (5,0) carbon nanotubes doped with nitrogen was investigated through the application of b3lyp/6-31g* at the level of theory on gaussian 03 software. a variety of stable and high abundance structures of nitrogen doped carbon nanotubes were considered in order to study the interaction between the mentioned gases in ...

Increasing concern over the air pollution has forced the man to develop the new technology for the better quality of life. In modern world, air pollution does not need any introduction. One of the major factors responsible for such degradation in the quality of life is air pollution. However, chief among them are carbon monoxide, sulphur dioxide, nitrogen oxides, ozone, etc. Nitrogen dioxide ca...
