BACKGROUND It has been suggested that dust exposure causes airway inflammation among cement factory workers. However, there is limited information on the mechanisms of this effect. We explored any associations between total dust exposure and fractional exhaled nitric oxide (FENO) as a marker of airway eosinophilic inflammation among cement production workers in Tanzania. We also examined possib...

introduction: metalworking fluids (mwfs) are widely used in metal working operations for cooling down, lubricating and reducing the friction between tools and work pieces which result in controlling the heat produced. exposure to mwfs causes several adverse effects including respiratory problems, skin diseases, cancer and even infertility. this study examines workers’ exposure to mwf mist and t...
