Exposure to Inhalable Flour Dust and Respiratory Symptoms of Workers in a Flour Mill in Iran

In 1999 the American conference of governmental industrial hygienists (ACGIH) proposed a threshold limit value (TLV) of 0.5 mg/m for flour dust with a sensitization notation. As part of this study, a relationship between flour dust concentrations and respiratory symptoms were examined. All 24 male flour subjects and 10 male controls were studied using air samples, ventilatory function testing, ...

Peak expiratory flow rate in flour mill workers.

The current cross-sectional study with a comparison group was undertaken to investigate peak expiratory flow rate (PEFR) in flour mill workers and to study relationship between reduction in PEFR and age, smoking, exposure to grain dust and respiratory morbidity. The study included 286 flour mill workers and equal number of neighbourhood controls group-matched for age. PEFR was measured by using...

Mycoflora study in a wheat flour mill of Argentina

THE MYCOFLORA OF THE ENVIRONMENT wheat conditioning, milling and screening, and filling zone, as well as, raw material -wheat-, intermediate product -grits- and end product -flour- on day 1, and after cleaning improvements -days 45 and 90- were studied in an Argentine wheat mill. Samples were incubated at 28°C for 5-7 days on Malt Extract Agar with chloramphenicol (100 mg L(-1)) and the results...

Title : Producing Fiber Flax Using Modern Machinery and Field Retting

approv Steven J. Knapp Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in Oregon around 1957 before newly developed technology and fiber cultivars were available. The purpose of this research was to explore the use of modern methods and new cultivars. Field studies were conducted to evaluate cultivars and optimum cultural practices that would produce the highest yi...
