Title Epidemiologic study on the skin lesions of workers exposed to N,N'-methylene-bis-(2-amino-1,3,4-thiadiazole) and of children in the neighbourhood of the factory
Bibliographic information 1985, Vol.11, Supplement 4, p.55-59. Illus. 6 ref.
Abstract The levels of N,N'-methylene-bis-(2-amino-1,3,4-thiadiazole) (MATDA) in the air of a bactericide production plant and in the neighbouring soil and river water were 0.1-0.8mg/m3, 6-2,650mg/kg and 0.5-2.0mg/kg, respectively. Of the 79 workers engaged in MATDA production, 44% suffered contact dermatitis and 72% showed skin pigmentation changes. All the exposed workers had experienced dermatitis at some time. Pigmentation changes were also observed in children of workers residing near the plant. Changes in the formulation of the product from a powder to an emulsion and recycling of process wastes reduced the dermatitis problems to a minimum.
