| Description |
Impact of agriculture crop-residue burning (ACRB) was studied on pulmonary function tests (PFTs) of 50 healthy subjects (13-53 years). Human subjects with no previous history of lung disease were residents of five sampling sites. Investigations were carried out from February 2007 to January 2010 using spirometry. Simultaneously, concentration levels of suspended particulate matter (PM) and fine particulates (PM2.5 and PM10) were monitored using high volume sampler and Anderson Cascade Impactor, respectively. The PFTs show a significant (p<0.05) decrease, while PM shows momentous increase during exhaustive burning of wheat and rice crop residues. Effect of ACRB on the peak expiratory flow rate (PEF) is more than that on force expiratory flow (FEF25-75%). The PEF and FEF25-75% recovered to some extent on completion of burning period, while PFTs like force vital capacity and force expiratory volume did not show a significant improvement. Due to greater concentration of fine particulates during rice crop-residue burning (CRB) than wheat CRB, there was a greater effect on pulmonary functions. The ACRB, in general, poses more effect on the lower and upper age groups in comparison to the middle age group subjects. All the analyses are well supported with large significant levels (p<0.05) obtained by using the paired t-test.
