during charcoal production is associated with lung function deficits
and respiratory symptoms nonetheless; other factors could also give rise
to the similar respiratory disorders or problems. This study was
designed to ascertain the influence other impinging factors wield on the
respiratory symptoms and lung function deficits among workers at
wood-burning earth kilns.History of asthma significantly and negatively impinged on lung function
deficit among these workers. Duration of job amongst other factors did
not influence the prevalence of respiratory symptoms. Pre-employment
screening of workers for respiratory disorders may be a worthwhile
venture to pursue in the long term.
