The Effect of Cotton Wool Dust on Peak Flow Meter (PEF)of Textile Factory Workers in Mosul


ABSTRACT : BACKGROUND:Byssinosis is a disease caused by long exposure to cotton, hamp, and flax dust, it differs from occupationalasthma, it needs along period of exposure to develop and the worker gets adaptation on subsequent days afterMonday chest tightness. The over all prevalence of byssinosis was 22.4%.Byssinosis needs at least 10 years to develop,the prevalence and severity increased with increasing duration of exposure to cotton dust. processing of cotton ismore harmful to lungs, and this is due probably to high dust concentration, or the dust contains toxinsand other organic substances which decrease in later manipulations. OBJECTIVE :To find out the prevalence of byssinosis among textile factory workers in mousel.To through alight on the relationship between smoking and byssinosis among workers exposed tocotton wool dust. the relationship between duration of working in a textile factory and occurrenceof byssinosis PATIENT AND METHOD:Two hundred and fifty Mosul Textile factory male workers , occupationally exposed to cottondust, aged (22-65) years were randomly selected and were interviewed to get information aboutage, work duration, smoking habit, and about chronic cough, phlegm, wheeze and chest tightness,and workers were examined clinically, and special considerations attended to the chest. Theworkers involved in this study were in good health at the time of engagement to this work, and anyworker with bronchial asthma, or other chest diseases were excluded. by history .Peakedexpiratory flow (PEF) was carried out for all 250 workers by Right's Peak flow meter(W18416.Harlow, England). RESULT AND DISCUSSION:All of the workers were male their age ranged 22-65 years with mean age of 45.3 years, in thosebetween 31-40 years the incidence was 10.8%, this increased to 49.3% in those whose age wasover 51 years. The mean work duration was 18.2 years, ranged (2-44) years. The prevalence was12.6% in age groups 10-19 year work duration, 47.2% in 20-29 years, and 49.2% in those over 30year work duration. In age group 10-19 years work duration moderate cases of byssinosis was4.7% and no any sever case and mean PEF 106%, while in age group over 30 year work durationthere was 33.3% moderate and 7.9% sever cases of byssinosis and mean PEF 94.9%.increasedprevalence and severity of byssinosis in sections where the dust concentration was high. In theweaving room 12%, were byssinotic, where the dust concentration was lowest, 25%, in spinningroom where the dust concentration was higher, while in ginning room where the dust concentrationis highest the prevalence was 41.8%. . CONCLUSION:We have shown that the prevalence of byssinosis is still high in MousalTexitle factory- Iraq. It isstatistically estimated that the prevalence of byssinosis after 8 years will be 35.2%, the reason forthis may be attributed to bad occupational safety measures..
