[Problems of environmental exposure to toxic effects of glutaraldehyde in medicine].

Glutaraldehyde is an antibacterial and antiviral agent commonly used for cleaning and disinfection of endoscopic equipment. The accepted glutaraldehyde air-concentration is 0.2 ppm. The irritant action, allergic potential and possible neurotoxicity of glutaral have been reported. Red eyes, cough, headache and running nose are most frequent symptoms of glutaral activity. The incidence of bronchial asthma and contact dermatitis has also been reported. In order to avoid occupational hazards of glutaraldehyde closed washing-disinfection systems, proper ventilation (20 cycles per hour), vapour recovery safety nozzle and neutralizing agent should be used.
