“…El Batawi (1962) found that symptoms of byssinosis were actually more prevalent in ginning (38%) and bale pressing (53%) than in carding (27%), although the last operation had a higher proportion with grade II byssinosis. Ginning seemed safer in Greece, there being no cases of byssinosis in 70 workers evaluated by Kondakis and Pournaras (1965). There were no byssinotics in a study by Palmer et al (1974) in the southwestern United States.…”

Diem, L., and Weill, H. (1977). Thorax, 32,[281][282][283][284][285][286]. Respiratory health and dust levels in cottonseed mills. Four cottonseed mills in the southern United States contained high levels of total and respirable dust. A survey of 172 workers showed low prevalences of byssinosis (2-3%) and chronic bronchitis (4%). Mean baseline (out of dust) lung function values were normal. Mean functional declines over the working shift were present on Monday and absent on Friday, indicating an acute bronchoconstrictor response. Despite limitations in translating measured dust levels into estimates of individual exposures, the overall dose-response relationship seems to differ from that found in the cotton textile industry.Byssinosis may result from inhaling any of several vegetable fibres under a variety of occupational exposures. The cotton textile industry has been the locus of most of the systematic studies of the disease. Non-textile exposures to cotton dust have received little attention, probably because these operations are predominantly rural, dispersed, and seasonal, and have a high turnover of unskilled labour.As a result of the morbidity and disability from byssinosis in textile workers, governments have undertaken to regulate the permissible exposure to cotton dust. The major task is to define a safe and feasible limit of exposure. It is reasonable also to consider whether to apply the same standard to all sources of airborne cotton dust. The answer to this question should depend upon whether byssinosis is found in non-textile workers, and whether the dust-dose biologic-response relationship is similar to that in the textile industry.Cottonseed is an important product of cotton cultivation. Seed mills separate the raw cottonseed into 'linters' (attached short cotton fibres), hulls, and meats, the last being the source of oil and cake or meal. The early steps in processing involve removal of coarse trash by mechanical shakers, stripping the linters from hulls by revolving saws, and collecting the baling linters. These operations raise substantial amounts of dust. The cottonseed is not treated in any way before it reaches the mill. Study population and methodsIn the summer of 1975, we studied workers in four cottonseed mills in the southern United States. We attempted to recruit all workers in dusty jobs and a number of other cottonseed mill workers (thought to be only minimally exposed to dust) to serve as a comparison group. In three mills, we recruited as many workers as were willing to participate. In the fourth and largest mill, all workers in dusty jobs were recruited, and as many with minimal exposures as study time permitted. One hundred and seventy-two workers completed the interview; 153 completed function studies for inclusion in the Monday analysis (reasons for exclusion included having less than 40 hours off work before testing, or unexpected absence from work). Of these 153 workers, 145 were available for study on Friday of the same week.Frequency distributions of the ages and length o...

“…But the prevalence of byssinosis in the ginnery halls is less than that reported in Egypt. Kondakis and Pournaras (1965) did not find byssinosis in cotton ginneries in Greece. Table 3 shows the prevalence of byssinosis in the main processes of ginning and farfara in Egypt and 4.…”

“…The prevalence of byssinosis in cotton ginneries has been described in many different countries (Gilson, Stott, Hopwood, Roach, McKerrow, and Schilling, 1962;Batawi, 1962;Batawi et al, 1964;Kondakis and Pournaras, 1965). In the Sudan, byssinosis caused by cotton dust is a notifiable and compensatable industrial disease under the Workshops and Factories Ordinance, 1949 (Khogali, 1966 (Schilling, Vigliani, Lammers, Valid, and Gilson, 1964), translated into Arabic, was used.…”

Khogali, M. (1969). Brit. J. industr. Med., 26,[308][309][310][311][312][313]. A population study in cotton ginnery workers in the Sudan. An epidemiological study in cotton ginneries in the Sudan covered 323 permanently employed ginnery workers, a random sample of 35 seasonal farfara workers, and a control group of 24 members of a fire brigade. All the workers studied were men.The study showed a prevalence of byssinosis (defined as chest tightness starting on return from the annual holiday and continuing for at least three consecutive days) in 20 % of the ginnery workers and in 48-6 % of the farfara workers. Workers exposed to dust showed a mean fall in F.E.V.1.o of -0 10 litre during the shift, while workers not so exposed showed a mean rise of +0-23 litre; this difference was statistically significant.

Objectives:To assess the effect of cotton dust on pulmonary function tests of workers in a cotton textile factory. Subjects and Methods: One hundred forty one male workers aged 21-60 years. Out of them 67 from Pepsi factory considered as controls ,and 74 from cotton textile factory in Mosul ,during the period from the 1 st of January 2007 to the 30 th of April 2007.The pulmonary function tests studied were :FVC ,FEVI , FEV%.PEF and FEF25-75%. Results: Workers in cotton textile factory showed a significant reduction in the levels of FVC and of FEV1 at age of 40-60 years as compared to control workers. Conclusions:The results showed that cotton dust causes a significant reduction in FVC and FEVI as age advances. P
