For some time there has been debate over the optimal size of a pollen count.
If one watches television or listens to the radio in the summer one is told that the pollen count will be so much.
Information about the pollen count is given regularly throughout the summer as part of our weather forecasts.
One possible scenario for the coming years is that pollen count could increase to 20 grams per cubic meter.
A pollen count for a specific layer can be produced by observing the total amount of pollen categorized by type (shape) in a controlled sample of that layer.
To reduce the effect of interannual variability in flower production, the pollen counts of both years were summed before percentages were calculated.
It carries out pollen counts, so that people know about the effects of pollen and how it can trigger allergies, which can trigger asthma.
We are aware that the summer months can cause particular problems for patients with asthma because of factors such as high pollen counts.
