Abstract Inhalation of grass pollen can result in acute exacerbation asthma, prompting questions about how reaches metropolitan areas. We establish typical atmospheric Poaceae (grass) concentrations recorded at two samplers within the Sydney basin eastern Australia and analyse their correlation with each other meteorological variables. determine effect synoptic regional airflow on transport dur...

In this study, Particulate Matter (PM) samples, collected during 2 summer and 2 winter months over a long-term period (1984–2012) at a suburban site in Athens (Greece), were used in order to examine the connection between Sahara dust long range transport events and mass concentrations of the aerosol mineral component, as well as the relative abundance of specific crustal components. As a result...

We present month-long observations of speciated acyl peroxy nitrates (APNs), including PAN, PPN, MPAN, APAN, and the sum of PiBN and PnBN, measured at the Mount Bachelor Observatory (MBO) as part of the INTEX-B collaborative field campaign during spring 2006. APN abundances, measured by thermal dissociation-chemical ionization mass spectrometry (TD-CIMS), are discussed in terms of differing con...

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 pollen counts at two sampling stations located 40 km apart, in south-western Spain (Cordoba city and El Cabril nature reserve) over the period 2010-2011. Pollen grains were captured using Hirst-type volumetric spore traps. Analysis of...

Aerosols suspended in the atmosphere negatively affect air quality and public health promote global climate change. The Guanzhong area China was selected as study area. Air data from July 2018 to June 2021 were recorded daily, 19 haze periods for this study. Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model used simulate mass transport trajectory during period classify for...

Los cultivos transgénicos aparecen como respuesta a la preocupación por abastecer gran demanda alimenticia derivada del crecimiento poblacional. Sin embargo, diferentes autores han argumentado que los contaminan genéticamente tradicionales y ocasionan pérdida de biodiversidad agrícola nativa. Aunque este trabajo no aborda afectación tradicionales, explica importancia tipo estudios su posible us...

The GMOS (Global Mercury Observation System) project has the overall goal to develop a coordinated observing system monitor mercury on global scale. Here we present long-term (2011–2020) air monitoring data obtained at Listvyanka station located shore of Lake Baikal, Siberia. shows obvious seasonal variation background concentration in air, which increases cold and decreases warm season. short-...

BACKGROUND The Himalaya with its altitude and geographical position forms a barrier to atmospheric transport, which produces much aqueous-particle monsoon precipitation and makes it the largest continuous ice-covered area outside polar regions. There is a paucity of data on high-altitude microbial communities, their native environments and responses to environmental-spatial variables relative t...
