title: [Contact dermatitides due to dichloropropiophenone].
abstract: Contact-allergy eczemas due to dichloropropiophenone. Following an exposition to p-beta-dichloropropiophenone (DCP) of less than one year nine skilled chemical plant workers were taken ill with an eczema from contact allergy, particularly badly seizing their faces, necks, hands and forearms. In all workers in question has been recognized a job connected skin disease with bodily impairment of 20 to 30%. The test concentration of DCP was determined at 0.01% (testing vehicle: oil). Nonexposed persons showed response only at 0.5% DCP concentration (50 times higher percentage!) by falling sick of an uncomplicated irritation erythema, strickly localized. With regard to the almost obligatory tendency towards sensitization there must be strict observation of the stringent measures of a labour protection, and moreover, in the future there should be established a closed system of automatic control.
