Sixteen high-resolution marine aerosol (Na, SO4 ) records from spatially distributed International Trans Antarctic Scientific Expedition (ITASE) ice cores spanning the last ~200 years from the Pine Island-Thwaites and Ross drainage systems and the South Pole are used to examine sources (sea spray and frost flowers) and transport pathways of marine aerosols into West Antarctica. Factors contribu...

background: melaleuca cajuputi essential oil in aerosol spray was evaluated against the dengue vectors aedes ae­gypti and ae. albopictus at low cost housing flats in section 10, setapak, kuala lumpur, malaysia. methods: essential oil in aerosol viz: 5% and 10% of concentrations were sprayed for 5 seconds each towards hung mos­quitoes in 5 cylindrical net cages. aerosol weights were recorded bef...

The present study is the first attempt to examine temporal and spatial characteristics of aerosol properties and classify their modes over Iran. The data used in this study include the records of Aerosol Optical Depth (AOD) and Angstrom Exponent (AE) from MODerate Resolution Imaging Spectroradiometer (MODIS) and Aerosol Index (AI) from the Ozone Monitoring Instrument (OMI), obtained from 2005 t...

Chitosan-graft-polyethylenimine (CHI-g-PEI) copolymer has been used for theimprovement of low transfection efficiency of chitosan. The present study aims to test thepulmonary toxicity and efficiency of CHI-g-PEI as an aerosol gene carrier. Mice were exposedto aerosol containing green-fluorescent protein (GFP)-polyethylenimine (PEI) or GFP-CHIg-PEI complexes for 30 min during the development of ...

background: bio aerosols include airborne micro-organisms such as bacteria, fungi, viruses, etc and their products. exposure to a bio aerosol is linked with a broad spectrum of health problems, including infectious diseases, acute toxic effects, allergies, and cancer. the aim of this study was to evaluate the quality and quantity of bio aerosols found in the air of different wards in valiasr ho...

This dissertation presents a scientific framework that facilitates enhanced understanding of aerosol source – receptor (S/R) relationships and their impact on the local, regional and global air quality by employing a complementary suite of modeling methods. The receptor – oriented Positive Matrix Factorization (PMF) technique is combined with Potential Source Contribution Function (PSCF), a tra...
