Respiratory system 554 INDEX

If tlie pollutant causes iui acute non carcinogenic risk, tlie inaximuin one hour concentration is used for C, and tlie acute reference exposure limit is used for tlie REL. Likewise, if tlie pollutant causes a clironic non carcinogenic risk, tlie one year average concentration is used, as is tlie clironic reference exposure limit. In tliis procedure, a Iiazard index is calculated for each pollutant separately, and tlien tlie indices are summed for each toxicological endpoint (i.e., tlie respiratory system, tlie central nervous system, etc.). Finally, tlie total hazard index is tlien compared to a value wliich is considered significant. [Pg.415]

It is a mobile, narcotic, flammable liquid whose over-exposure irritates eyes and upper respiratory system (Merck Index). It has a sweet-ethereal, fruity taste in water (Arctander, 1967). An odor threshold of 17 ppm in water was given by Mulders (1973b). [Pg.170]
