Overview

Occupational lung disease may be classified according to the type of inhalant into 3 groups: inorganic dust, organic dust, and agents other than inorganic and organic dust.

Classification

• Occupational lung disease may be classified according to the type of inhalant into 3 groups:
  • Inorganic dust
    • Such as silicates, carbons, and metals
  • Organic dust
    • Thermophilic fungi, true fungi, bacteria and animal proteins
  • Agents that are neither organic or inorganic
    • Chemical sources, gases, vapors, fumes and aerosols

Chemicals, gases, fumes, vapors and aerosols

• Farmer's lung (Macropolyspora faeni) • Grain handler's lung (Thermactinomyces vulgaris) • Humidifier or air conditioner lung (T. sacchari) • Aspergillus • Cryptostroma corticale • Aureobasidium pullulans • Penicillium species

• Bacillus subtilis • B. cereus • Bird fancier's disease

• Silica ("silicosis") • Asbestos ("asbestosis") • Talc (hydrated Mg silicates; "talcosis") • Kaolin or "china clay" (hydrated aluminum silicate) • Beryllium ("berylliosis") • Mica (principally K and Mg aluminum silicates) • Portland cement • Aluminum silicates (sericite, sillimanite, zeolite) • Nepheline (hard rock containing mixed silicates) • Diatomaceous earth (Fuller's earth, aluminum silicate with Fe and Mg)

• Coal dust ("coal worker's pneumoconiosis") • Graphite ("carbon pneumoconiosis")

• Tin ("stannosis") • Aluminum • Hard metal dusts (cadmium, tungsten, titanium and cobalt) • Iron ("siderosis") • Antimony • Hematite (mixed dusts of iron oxide, silica and silicates; "siderosilicosis") • Mixed dusts of silver and iron oxide ("argyrosiderosis") • CuSO4 neutralized with hydrated lime (Bordeaux mixture; "vineyard sprayer's lung") • Rare earths (cerium, scandium, yttrium, lanthanum)

Chemical sources: • Synthetic - fiber lung (Orlon, polyesters, nylon, acrylic) • Bakelite worker's lung pathways • Vinyl chloride, polyvinyl chloride powder Gases: • Oxygen • Oxides of nitrogen • Sulfur dioxide • Chlorine gas • Methyl isocyanate Fumes: • Oxides of zinc, copper, manganese, cadmium, iron, magnesium, nickel, brass, selenium, tin, and antimony • Diphenylmethane diisocyanate • Trimellitic anhydride toxicity Vapors: • Hydrocarbons • Thermosetting resins (rubber tire workers) • Toluene diisocyanate (TDI - asthmatic reactions prominent) • Oxygen • Mercury Aerosols: • Oils • Fats • Pyrethrum (a natural insecticide)
