The pollen and mould ratio has surged this year compared to previous years in Islamabad, according to a recent report by the Pakistan Meteorological Department. The measurements, crucial for allergy sufferers, indicate a significant increase in airborne allergens from trees, grass, weeds, and moulds in the region.
Using a Burkhard sampler that operates continuously for 24 hours, pollen and mould spores are collected and analysed on slides by experts to determine their quantity and type. The severity of pollen and mould counts is measured in grains per cubic meter, with each type of pollen assigned a severity level based on its concentration found on the slide.
Today’s readings reveal a notably high pollen ratio in the city, with Paper Mulberry registering at 45,103, which is categorized as “very high” on the severity scale. Pine, Grass, Cannabis, and Alternaria are also notably elevated at 22, 24, 25, and 27 respectively, contributing to a total ratio of 45,201.
The interpretation of pollen and mould counts and their correlation with allergy symptoms is complex, with symptoms varying among individuals and at different levels of pollen and mould concentrations. Weather conditions further complicate the situation, as allergy sufferers often find relief on rainy, cloudy, or windless days due to limited pollen movement. Conversely, hot, dry, and windy conditions lead to higher pollen and mould concentrations, exacerbating allergy symptoms.
Individuals sensitive to these allergens need to be vigilant, as even small concentrations can trigger symptoms. Extremely sensitive individuals may experience severe reactions. The findings underscore the need for allergy sufferers to take necessary precautions and consult healthcare professionals for appropriate management strategies.
As the pollen season progresses, continued monitoring of pollen counts and weather conditions will be essential for mitigating allergic reactions in the affected population.
