ICP-MS Detection and Non-carcinogenic Risk Analysis of Lead in Cable Flue Gas

Abstract

The lead content in the flameless combustion flue gas for three types of cable was measured using inductively coupled plasma mass spectrometer (ICP-MS) under 5 different temperatures ranging 300~700°C, and the non-carcinogenic risk analysis model was employed to estimate human health risk under different physical activities. Experimental results showed that the lead concentration sorted order for three kinds of cable flue gas is ZR-YJV>YJV> ZR-RVV. With the rise in temperature the lead content in the cable smoke increases, and the lead content at 600~700°C is higher than that of the national standard. Non-carcinogenic risk analysis demonstrated that at 600~700°C the Rf values of these three kinds of cables are at 1~100 level. But during extremely heavy physical activities, the Rf values of YJV and ZR-YJV reached 106.05 and 120.49 levels at 700°C respectively, which are 100 times more than the risk limit and have a strong non-carcinogenic risk.
