Background Recent studies have observed positive associations between outdoor air
pollution and emergency department (ED) visits for asthma. However, few have examined …

BACKGROUND: Atmospheric pollen counts are ubiquitous data, however, few guidelines
exist for interpreting them. A fundamental problem involves appreciating spatial variability in …

Urban trees provide a range of environmental and public health benefits. However, urban
trees may also have an adverse effect on human health by increasing exposure to pollen …

BACKGROUND: There is increasing interest in the daily pollen count, with pollen-sensitive
individuals using it to determine medication use and researchers relying on it for …

Airborne pollen counts are mainly determined using a volumetric suction sampler based on
the impact principle, that is, a Hirst-type spore trap. As a consequence of their volumetric …

The study assesses differences in the results retrieved by Hirst samplers of the same model
in order to determine their sampling variability. Five seven-day Burkard spore traps were …

Pollen allergies are one of the most common health problems in the United States and over
20% of Americans are sensitized to the pollen produced by common ragweed (Ambrosia …

A palynological study was carried out on 28 corpses brought in one year (June 2003–May
2004) to the morgue of the Institute of Legal Medicine of Parma (Northern Italy). This …

The airborne pollen concentration in the city of Badajoz was measured in two locations 2.9
km apart. The measurements were taken from January to June between 2009 and 2012 …

Characterizing the variation in bioaerosol concentrations is important for the estimation of
health effects associated with bioaerosols and planning exposure assessment strategies …
