Abstract
Hydrogen peroxide is a colourless liquid that is normally handled as an aqueous solu-tion.Hydrogen peroxide is commonly used in industry for disinfecting, bleaching and as a general oxidizing agent. The main use (48%) of hydrogen peroxide in the EU is for bleaching pulp. Other uses include manufacturing chemicals and using it as an intermediate in the synthesis of chemicals such as sodium perborate, sodium percarbonate, hydroquinone, hydrazine, organic peroxides and many others. It is used in bleaching textiles and other products, wastewater and waste gas treatment, disinfection, beverage packing, surface treat-ment, etching and cleaning. Small quantities are used in consumer products such as cosmetics, toothpaste and deodorants.Hydrogen peroxide causes irritation of the respiratory tract and eyes. Inhalation of high concentrations of the vapour or mist of hydrogen peroxide may cause extreme irritation of the nose and throat. Even short periods of exposure may cause stinging and watering of the eye and exposure to 9.2 mg/m3 has been reported to cause lung irritation in humans. Higher levels of exposure may cause headache, dizziness, vomiting, diarrhoea, tremors, numbness, convulsions, pulmonary oedema, unconsciousness, and shock. Contact of hy-drogen peroxide with the skin can cause severe skin damage. An irritant of the eyes, mucous membranes, lungs and skin is a critical effect of hydrogen peroxide. The MAC value for hydrogen peroxide was calculated on the basis of the LOAEL (0.83 mg/m[sup]3[/sup]) value and uncertainty factor (Uf= 2). The MAC value of 0.4 mg/m[sup]3[/sup] is recommended and the value of STEL of 0.8 mg/m3. An additional notation of hydrogen peroxide is C – corrosive compounds.
