Title Symptoms of exposure to o-chlorobenzylidenemalononitrile
Original title o-Chlorobenzylidene malononitrile no bakuro ni yoru shōjō ni tsuite [in Japanese]
Bibliographic information Sep. 1987, Vol.35, No.9, p.625-631. Illus. 3 ref.
Abstract o-Chlorobenzylidenemalononitrile (OCMB) is a riot-control agent. Containers contaminated with the compound can be included in metal scrap. Industrial injury patients showed abnormality in smelling, nasal respiratory resistance, or other symptoms believed to be caused by exposure during work with OCMB. In 1 case (2 episodes), the subject was exposed and continued to work for more than 2 hours in spite of obvious and strong symptoms in the eyes, nose, throat and chest. Slight reddening of the nasal and laryngeal mucosae, and elevation of nasal respiratory resistance and lower airway resistance were observed. Taste was normal but olfactory sensitivity was reduced and a slight reddening of the trachea and bronchial mucosa were noted by bronchoscope. In about six months, recovery was essentially complete. In 1 case (1 episode), the subject was exposed, and stopped working immediately when symptoms appeared. In this patient, all findings were almost normal. Scrap metal workers and others who may be exposed to OCMB should always wear protective gear.
