Type: Research



Scavenging profession and waste management services have become a standing means of livelihood despite the odours or smell that ensues from the material being handled.

The effect of odours and decomposing materials in the respiratory tract of scavenging practitioners and waste management personnel’s was studied using 30 subjects divided into three(3) groups A,B and C. Each group consist of 10 persons.

Group A is the control, Group B is the scavenging professionals, and Group C is the waste management personnel’s. The aim of the study is to know if the daily odour or smell from the dust bins and waste materials actually have effect in their respiratory tract and the possible bacteria or fungi that can be found in their system. Culture media test, coagulase test, catalase test and Gram stain were the bacteriological tests used to identify the bacteria and fungi in the nasal and throat swabs collected from the subjects while the lung volumes and capacities of the subjects were measured using spirometer. The results of this research showed that bacteria such as salmonella species, streptococcus species, klebsiella species, staph. aureus, pseudomonas, Bacillus subtilis, E. Coli and fungi were isolated from the specimens.

The lung volumes and capacities of the scavengers and waste management personnels were not affected by the odours they are exposed to. The result of the study showed no significant change (p>0.05) hence the respiratory passages of the scavengers and waste management personnels are safe despite the bad and nauseating odours they face on daily basis during their work. It can be deduced from this study that the commonest organism the professionals contract is fungi and salmonella organism.
