Description:
Irridations of C3H5Cl/NOx, C3H5Cl/C2H6/NOx, and C2/NOx mixtures were conducted in a 22.7-m3 Teflon smog chamber, operated in a static mode. he irridated mixtures were tested for mutagenic activity by periodically exposing Salmonella typhimurium strain TA100 to the smog chamber ef fluent during the irridation. he allyl hloride photooxidation products total mutagenic activity was found to be dramatically dependant on the presence of Cl atom reaction products. n the absence of C2H6, which is used as a Cl atom scavenger, the observed mutagenic activity of the irridated C3H5Cl/NOx mixture at long extent of reaction was 13 revertants-plate-1h-1 (ppb C3H5Cl consumed)-1. owever, when sufficient C2H6 was 1.4 revertants-plate-1h-1 (ppb C3H5Cl consumed)-1. nder conditions of excess C2H6, the mixture is approximately 30 times more mutagenic than that previously observed for the mutagenic activity of the photooxidation products of porpylene, the nonchlorinated analogue of allyl chloride. he observed mutagenic activity in the presence of excess C2H6 is consistent with the total response caused by chloroacetaldehyde, a primary C3H5Cl photooxidation product.
