Size distribution and concentration of fungal aerosol in animal premises of a zoological garden
This study aimed to assess the levels of fungal aerosol in animal premises (tapirs, giraffes, pygmy hippos, monkeys, meerkats, pheasants, ostriches, exotarium) of the Krak ów Zoo. The bioaerosol samples were collected using a six-stage Andersen impactor to assess the concentrations and size distribution of airborne fungi. Particulate matter (PM10, PM4, PM2.5 and PM1) concentration was assessed using DustTrak Aerosol Monitor. PM concentrations were relatively low (0.048 –0.204 mg/m3) and did not exceed the limit values for occupational exposure. Also, the levels of fungal aerosol in almost all cases did no...

Alternaria spores in Emilia-Romagna, Northern Italy: current diffusion and trends
AbstractSince the end of the 1990s, the aerobiological network managed by the Regional Environmental Agency in Emilia-Romagna, Italy, started a systematic monitoring of different types of fungal spores, in particular Alternaria. This activity is of outstanding interest due to the various detrimental effects on human beings and on vegetation associated with Alternaria spores presence in the atmosphere. Daily concentration values of Alternaria spores are available from the Emilia-Romagna network in 10 stations. The availability of these data allows to set up a detailed analysis of the presence of Alternaria spores in differe...

An assessment of ragweed pollen and allergen loads in an uninvaded area in the Western Black Sea region of Turkey
AbstractAmbrosia artemisiifolia L., known as common ragweed, is an invasive and allergenic plant that has begun to expand its presence in Turkey.

Extractable lipids from Phleum pratense pollen grains and their modifications by ozone exposure
AbstractGrass pollen grains are an important source of aeroallergens eliciting respiratory allergic diseases worldwide. In the field of allergology,Phleum pratense pollen is considered as a model for other grass taxa. Upon contact with the aqueous phase of mucosa membranes, lipids are co-delivered from pollen grains with allergens. Lipid molecular species have pro-allergic, pro-inflammatory and immunomodulatory effects on the cells of the allergic immune response. The quantitative analysis ofPhleum pratense pollen lipids is missing in the literature. In this work, the total mass of lipids extractable by methylene chloride ...

Multi-point analysis of airborne Japanese cedar ( Cryptomeria japonica D. Don) pollen by Pollen Robo and the relationship between pollen count and the severity of symptoms
In this study, we addressed Pollen Robo. First, we examined whether Pollen Robo can accurately countC. japonica pollen and found that Pollen Robo was useful during the major pollen season. However, it sometimes counts non-pollen particles and other pollen rather thanC. japonica pollen. Therefore, it is not useful when a small amount of pollen is dispersed such as the start day of the pollen season. Next, we examined the daily dispersion ofC. japonica pollen and it was shown that it is related to the distance between sampling locations. However, factors other than distance may be involved. Another matter of concern is the r...

On possibilities of assimilation of near-real-time pollen data by atmospheric composition models
AbstractAssimilation of pollen observations for increasing accuracy of the deterministic model forecast and reanalysis faces several roadblocks. The most-evident problem today is the long delay of the data because of the manual character of the observations. Automatic monitors are about to eliminate this issue but more are on the way. This paper shows that the classical assimilation of the model state, i.e. pollen concentrations, has very little effect on the forecasts. Due to short relaxation time of the system, the updates generated by the assimilation are forgotten within a few hours. In a search of approaches with a lo...

The objective of the study is to evaluate the pollen and allergen concentration in two cities in the north-west of the Iberian Peninsula, Porto (Portugal) and Ourense (Spain), and analyse how weather parameters and environmental pollutants can affect the patterns of pollen and allergen airborne distribution. The pollen sampling was conducted, during 2018, using a Hirst volumetric sampler, and Pla a 1 aeroallergen was collected using a Burkard multivial cyclone sampler. The pollen counting was obtained following the Spanish Aerobiology Network methodology. Aeroallergens were quantified by ELISA method using a Pla a 1-specif...

Can air microbiota be a novel marker for public health? A sampling model and preliminary data from different environments
AbstractNext-generation sequencing (NGS) and advances in microbiota knowledge are opening new perspectives for environmental microbiology and public health. Massive parallel sequencing of bacterial DNA is providing new insights to unravel microbial dissemination in different matrices, including air. Here, we have assessed the air biodiversity in several indoor environments by NGS-based metagenomics and compared results with respect to classical approaches. Environmental sampling was achieved in three exemplificative indoor locations: offices, recreational facilities and public restrooms. Sampling was performed by active (s...
