“…There is some indication that work in the textile industry may increase the risk of sinonasal cancer, but the etiological agents are unknown. 18 Our analysis shows that employment in spinning and weaving workshop produces higher total cancer incidence. The cancer risk was 35% higher than expected from national rates.…”

Altogether 14,650 workers employed at least for 1 year a the textile factory in Alytus, Lithuania, were included in the cohort and followed during the period from 1978 to 1997. The standardized incidence ratio (SIR) for men was 1.28. The incidence of esophagus cancer was significant higher (SIR 3.42). It increased only slightly for lung (SIR 1.35). In the women cohort, SIR was 1.05. However, there was a significant increase of the incidence of gallbladder cancer (SIR 3.19). Among textile-processing (spinning and weaving departments) women workers, we found elevated total cancer incidence (SIR 1.35), incidence of breast cancer (SIR 1.49), and cervical cancer (SIR 1.82). In this cohort increased SIR values were observed for more than 10 years since first exposure for all cancer (SIR 1.70) and cervical cancer (SIR 2.44).

“…While a number of studies have evaluated health outcomes among paper mill workers, and a subset have focused on the soft tissue paper mill workers who are the focus of our JEM, there is a very limited published literature on dust levels in soft tissue paper mills. We have incorporated exposure estimates from our own previous studies, which documented total dust levels from <3 mg/m 3 10–12 to as high as 40 mg/m 3 9,13 between the 1970s and 1990s, into the JEM described here. The mean inhalable dust levels among paper production workers in two German soft tissue paper mills evaluated in the early 2000s by Kraus et al 15,16 ranged from 10 to 12 mg/m 3 , with very large standard deviations on the order of 15 to 19 mg/m 3 , indicating quite substantial variability in exposure and highlighting the challenges in summarizing exposures in this industry.…”

“…Reports of paper dust exposures among soft tissue paper mill workers are sparse in the literature. We reported total dust levels in Swedish soft tissue paper mills in the 1970s through 1990s as ranging from <3 mg/m 3 10–12 up to 20 to 40 mg/m 3 9,13 . In a 1990 characterization of paper dust exposures in Swedish soft tissue paper mills, we measured total dust concentrations of 0.2 to 2.8 mg/m 3 at one of the mills studied here, 21 and we have previously estimated exposures among Swedish paper machine workers from <1 to >5 mg/m 3 14 using a combination of measurement data and expert judgment.…”

“…8 There have been relatively few studies on soft tissue paper dust exposures and associated health effects, primarily in Sweden and Germany, but those that have been conducted have indicated or shown an association between high exposures and respiratory problems, including reduced lung function, asthma, and nasal and other respiratory symptoms. [8][9][10][11][12][13][14][15][16][17][18] Järvholm 9 noted that many health effects have been associated with, but not convincingly demonstrated to result from, from paper dust exposure, and that additional studies are needed to identify and elucidate possible biological mechanisms of harm.…”

Background Total paper dust exposure has been associated with respiratory problems among workers in the soft tissue paper industry. However, a comprehensive job exposure matrix (JEM) has not been developed for application to this industry. Our study was intended to address this need and to support further studies of mortality and morbidity in a cohort of Swedish workers from this industry. Methods We evaluated four participating soft tissue paper mills in Sweden. We combined information on process and equipment status from the mills with knowledge of the mills obtained through research efforts and paper dust measurements made at all four mills to develop a semi‐quantitative JEM with seven dust exposure levels. The JEM was targeted at workers enrolled into a soft tissue paper mill cohort and working any time between 1960 and 2009. Results The JEM includes a total of 14 421 cells, with each cell corresponding to the exposure for a job title, department, or work location for a one‐year period. Exposure levels in the JEM were estimated to decline at three of the four mills from 1971 to 2009, but overexposures (ie, exceedances of the relevant occupational exposure limits) remained common at the end of the period. Conclusions The JEM results highlight the need for ongoing exposure control efforts in the soft tissue paper industry, and will inform ongoing epidemiological studies of the health effects of exposure to paper dust in Sweden. It is freely available for use by other researchers.

StreszczenieWstęp: Celem badania była ocena możliwości transportu cząstek biologicznych przez naturalne, syntetyczne i sztuczne włókna. Materiał i metody: Równoczesne pobieranie próbek pyłu osiadłego i aerozolu włóknistego przeprowadzono w 3 zakładach przetwarzających naturalne (bawełna, jedwab, len, konopie), syntetyczne (poliakrylonitrylowe, poliamidowe, polipropylenowe, poliestrowe) i sztuczne (wiskozowe) materiały włókniste; w 2 stajniach, gdzie hodowano konie i owce; w 4 domach, w których mieszkały psy i koty, oraz w 1 pawilonie zoologicznym dla lwów. Wszystkie próbki włókien analizowano laboratoryjnie, żeby okreś-lić stopień ich mikrobiologicznego zanieczyszczenia. Wyizolowane szczepy były identyfikowane jakościowo. W celu rozpoznania naturalnego upakowania i struktury badanych włókien, które mogą wspomagać transport cząstek biologicznych, przeprowadzono ich analizę skaningowymi mikroskopami elektronowymi. Wyniki: Zarówno osiadłe, jak i zawieszone w powietrzu włók-na transportowały takie same szczepy drobnoustrojów. Wszystkie włókna syntetyczne, sztuczne oraz włókna jedwabiu, które występują w środowisku jako osobne nici o gładkiej powierzchni, były wolne od zanieczyszczeń mikrobiologicznych. Naturalne włókna o luźnym upakowaniu i szorstkiej strukturze (np. runo owcy, sierść konia), o snopkowym upakowaniu i septowanej powierzchni (np. len, konopie) lub skręconych wstęgach i pofałdowanej strukturze (bawełna) transportowały do 9×10 5 jtk/g bakterii tlenowych, 3,4×10 4 jtk/g bakterii beztlenowych i 6,3×10 4 jtk/g grzybów, w tym patogenów klasyfikowanych przez Dyrektywę 2000/54/WE w 2. grupie zagrożenia. Wnioski: Ponieważ roślinne i zwierzęce włókna są zanieczyszczone znaczącą liczbą drobnoustrojów, w tym patogenów, powinny być mechanicznie eliminowane ze środowiska. Jeśli proces technologiczny na to pozwala, w zakładach pracy powinny być zastępowane włóknami syntetycznymi lub sztucznymi. W celu uniknięcia niepożądanej ekspozycji na szkodliwe czynniki mikrobiologiczne na włóknach zarówno w środowisku pracy, jak i poza nim powinny być wprowadzane środki techniczne, które wydajnie ograniczają obecność tych czynników.

Material and Methods: The simultaneously settled dust and aerosol sampling was carried out in 3 industrial facilities processing natural (cotton, silk, flax, hemp), synthetic (polyamide, polyester, polyacrylonitrile, polypropylene) and semi-synthetic (viscose) fibrous materials; 2 stables where horses and sheep were bred; 4 homes where dogs or cats were kept and 1 zoo lion pavilion. All samples were laboratory analyzed for their microbiological purity. The isolated strains were qualitatively identified. To identify the structure and arrangement of fibers that may support transport of microbial particles, a scanning electron microscopy ana...

Natural organic fibers – health effects

Abstract: Natural organic fibers are not causally linked with the well-known effects of some inorganic fibers, i.e. mesothelioma, lung cancer, lung fibrosis or some pleural diseases. The health effects of natural organic fibers, e.g. irritative effects, seem not to be linked to their fibrous shape.
