Pollen Count

Laser particle counts are the number of particles per cubic foot divided into 6 different size ranges. A laser beam literally counts the number of such particles as they are sucked past a detector. There is evidence that increased numbers of particles, particularly in the smaller ranges, are associated with heart diseases. That is why we measure it.

Tuesday's Comments

Today both pollen and spore counts are in low level with hot and humid weather. We are having different types of basidiospore in the air lately. The vast majority of basidiospores we see are mushroom spores. It is not common in our area to have more basidiospores than ascosores in the air. Ascospores appear before and after rainfall. But basidiospores are associated with rainfall over the past few weeks. Since we have had regular rain for the past month conditions are perfect for mushrooms. With moderate Ozone alert (Yellow) issued by MARC SkyCast throughout KC Metro area today persons with respiratory difficulties should consider restricting their outdoor activities

Pollen and mold counts are collected at Children's Mercy Hospitals and Clinics Hospital Hill location using a Hirst spore trap manufactured by Burkard Limited. Results are expressed as the mean value of the particles per cubic meter and represent an integrated 24 hour collection. These results may be published for media purposes provided the Children's Mercy Hospitals and Clinics logo is used to acknowledge the source.
