Abstract Dust aerosols have serious influences on different sectors such as the economy, climate change, pollution, transportation and public health. storms increased over Middle East especially impacting central Iraq lately. The goal of work is to identify possible dust sources pathways influencing study area. Using remote sensing data by employing monthly average Aerosol Index (AI-OMI), HYSPL...

Abstract In this study, we explore the conditions that led to unprecedented wildfire occurred in Chernobyl Exclusion Zone April 2020 and effect of fire on 137 Cs dispersal, as wildfires are important drivers resuspension, with potentially harmful consequences for receiving ecosystems. We characterised historical record between 2000 using MCD64A1.006 MODIS Burned Area Monthly Global 500 m datase...

The concentrations of Pb and Cd in the needles twigs fir spruce collected from 26 sites Eastern Tibetan Plateau were measured analyzed this study. mean 0.034 1.291 mg/kg, respectively, 0.101 2.511 twigs. These increased significantly with needle twig age peaked at 5 years. enriched compared needles. spatial distributions determined using inverse-distance-weighted interpolation method on basis c...

Atmospheric dispersion calculations are made using the HYSPLIT Particle Dispersion Model for studying the transport and dispersion of air-borne releases from point elevated sources in the Mississippi Gulf coastal region. Simulations are performed separately with three meteorological data sets having different spatial and temporal resolution for a typical summer period in 1-3 June 2006 represent...

The impact of regional and local weather and of local topography on intradiurnal variations in airborne pollen levels was assessed by analysing bi-hourly holm oak (Quercus ilex subsp. ballota (Desf.) Samp.) pollen counts at two sampling stations located 40 km apart, in southwestern Spain (Cordoba city and El Cabril nature reserve) over the period 2010-2011. Pollen grains were captured using Hir...

Ambient sulphur dioxide (SO2) measurements have been performed at a high altitude site in the semi arid region of western India, Gurushikhar, Mt. Abu (24.6 ̊N, 72.7 ̊E, 1680 m ASL), during different sampling periods span over Sep-Dec 2009 and Feb-Mar 2010. A global three dimensional chemical transport Model, GEOS-Chem, (v8-03-01) is employed to generate the SO2 profile for the entire region for t...

Levels of coarse (PM10-2.5) and fine (PM2.5) particles were determined between February 2004 and January 2005 in the city of Beirut, Lebanon. While low PM mass concentrations were measured in the rainy season, elevated levels were detected during sand storms originating from Arabian desert and/or Africa. Using ATR-FTIR and IC, it was shown that nitrate, sulfate, carbonate and chloride were the ...

The present study investigates aerosols distributions and a strong Sahara dust-storm event that occurred by early August 2018, in the South of Morocco. We used columnar aerosol optical depth (AOD), Angstrom Exponent (AE) volume size (VSD) as derived from ground-based observations 2 AERONET (AErosol RObotic NETwork) sun-photometers at Saada (31.63°N, 8.16°W) Ouarzazate (30.93°N, 6.91°W) sites, o...

Abstract The continually changing atmospheric conditions over densely populated coastal urban regions make it challenging to produce models that accurately capture the complex interactions of anthropogenic and environmental emissions, chemical reactions, unique meteorological processes, such as sea- land-breeze circulations. purpose this study is determine identify influence synoptic-scale wind...

Nitrogen (N) deposition significantly affects forest dynamics, carbon stocks and biodiversity, numerous assessments of N fluxes impacts exist in temperate latitudes. In tropical latitudes, however, there are few such assessments. this study, we measured the inorganic concentration (wet deposition) deposited rainfall pH throughout one year at boundary a reserve Malaysian Borneo. We considered th...
