| Abstract |
French translation of: K voprosu o toksikologiceskoj ocenke hloralja v processe ego vydelenija pri napylenii i zalivke penopoliuretanov. Gigiena truda i professional'nye zabolevanija, Moskva, USSR, June 1970, Vol.14, No.6, p.26-29. 2 ref. Occupational hygiene studies carried out during the application of certain polyurethane foams used for insulation, etc. disclosed that, in addition to isocyanates, tertiary amines, etc., chloral (CCl3CHO) also was given off during spraying or moulding. Chloral readily combines with water and water vapour to form chloral hydrate which is known to be acutely toxic (LD50=710 mg/kg, LC50=32 mg/l). Study of the toxic properties of chloral hydrate in cases of chronic exposure has shown that a concentration of 0.06 mg/l is already toxic and that a concentration of 0.02 mg/l is very close to the threshold limit value. The authors recommend that the ceiling value for chloral in air be fixed at 10 mg/m3. |
