the present research article highlights the metal (cd, cu, pb, zn and fe)distribution pattern in the rspm generated in different hot spot sites located at kochi, thequeen of arabian sea. these sampling sites are categorized under three different zonesas estuarine, riverine, and coastal. two sampling phases are selected in order to check theconsistency in pollution trend after a two year gap and...

the reaction of ch3o2 radicals with acetaldehyde on the solid surface of nh4no3 has been studied in a flow capillary reactor at low pressure and room temperature. the experiments were performed using epr spectrometer combined with the kinetic method of radicals freezing. peroxy radicals revealed an oscillation complex behavior during the process regarding to the phenomenon of radicals multiplic...

inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. the present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (pec) based microparticles containing antibacterials for the treatment of lung infections.chitosan polyelectrolyte complex...

background: welding is one of the most exercised industrial processes which welders are exposed to chemical and physical hazardous agents. this study was conducted to evaluate occupational and environmental exposures to aerosols generated by welding processes in a factory. methods: a total of 28 samples of aerosols were collected at 4 different locations including indoor, outdoor, source of wel...
