Pollen-monitoring: between analyst proficiency testing

Aerobiologia, 2017
This study presents the results of a Europe-wide training and Quality Control (QC) exercise carried out within the framework of the European Aerobiology Society’s QC Working Group and European COST Action FA1203 entitled “sustainable management of Ambrosia artemisiifolia in Europe (SMARTER)” with the aim of ensuring that pollen counters in Europe are ...

Monitoring airborne pollen in New Zealand

Journal of the Royal Society of New Zealand, 2021
Against a backdrop of increasing pollen allergy prevalence, this paper reviews the current state of knowledge of allergenic pollen loading in New Zealand. An unavoidable conclusion is that relevant available datasets are fragmentary, incomplete and out-of-date, with the last nationwide survey conducted >30 years ago.

AirborneCorylus pollen monitoring: Preliminary data

Aerobiologia, 1987
In 1984–5 and 1985–6 aerosporological data were collected in an experimental hazel-nut orchard in Cravanzana (High Langa) whereCorylus maxima andCorylus avellana cv. Tonda Gentile delle Langhe (TGL) were present with a prevalence of the latter. Inter variety crosses withC. avellana and interspecific hybridsC. avellana xC.

Monitoring respiratory effects of allergenic pollen

Nature Reviews Genetics, 2021
A study in Current Biology demonstrates the use of environmental DNA to monitor the abundance and composition of airborne grass pollen on a national scale. Integration with health data can infer the effects of specific pollen types on respiratory health.

Pollen Viability for Air Pollution Bio-Monitoring

Journal of Atmospheric Chemistry, 2004
Biological characterization of Corylus avellana L. and Pinus nigra L. pollen samples was carried out to determine the actual value of pollen as a bio-indicator of the effects of atmospheric pollution, using samples from plants naturally developed in sites controlled for air pollution.

Airborne pollen monitoring in Italy

Review of Palaeobotany and Palynology, 1990
Abstract Monitoring of airborne pollen in Italy is described with particular reference to the allergenic pollen which is principally represented in Italy by Betulaceae, Compositae, Corylaceae, Fagaceae, Gramineae, Oleaceae, Plantaginaceae and Urticaceae.

Automatic pollen monitoring.

2021
Pollen are among the most relevant al- lergens in Germany, in addition to allergens from house dust mite, cat, and dog. There is no legal limit for pollen flight, as pollen flight is predominantly not caused by anthropogen- ic activity. Thus, monitoring of pollen is also legally not part of the tasks of local authori- ties that are responsible for the ...

GFP‐tagged pollen to monitor pollen flow of transgenic plants

Molecular Ecology Notes, 2001
AbstractIn this study, the pollen‐active LAT59 promoter from tomato was used to express a green fluorescent protein (GFP) encoding gene in Nicotiana tabacum (tobacco) pollen. This promoter is preferentially expressed in anthers and pollen. Pollen in transgenic plants segregated in a 1 : 1 Mendelian ratio, and the plants were polymerase chain reaction ...

Monitoring indoor pollen over two years

Grana, 2014
The present study monitored a private apartment for pollen that had settled on the floor. Pollen was sampled and analysed from two rooms over a period of two years. The study showed that pollen accumulations indoors are dominated by wind-pollinated species reflecting the current flowering season.
