Upper Respiratory Allergic Symptoms And Effects Of Coal Dust On Pulmonary Function Tests Of Individuals Working In Coal Mines, Near Quetta, Baluchistan, Pakistan
This research was carried in order to know hazardous outcomes of coal mine dust on upper
respiratory system and their pulmonary function tests.
In this longitudinal cross sectional study, we evaluated upper respiratory allergic symptoms and
pulmonary function tests deterioration cause by coal dust exposure in coal mines workers near
Quetta, Baluchistan (from October 2018 to March 2019). A total of 336 individuals working in coal
mines meeting the preset selection criteria were selected and 41 normal healthy individuals of
same age and sex were selected from the general public of the same region who had never been
exposed to coal dust/coal mines and served as control group.
Their pulmonary functions were recorded by (SX MULTI SPIRO, USA) and for the analysis of
data SPSS version 18 was employed. The result shown in frequency and percentages, Chi
Square test was used and p value of < 0.05 was considered as significant.
Unprotected exposure to coal dust for longer period of time has bad impact on pulmonary
function test and biochemical parameters and is associated with increased frequency of upper
respiratory tract allergic symptoms.
