摘要: Benzene (B), toluene (T), ethylbenzene (E) and xylene (X) known as BTEX are commonly observed in the refinery industrial area acknowledged that pose a threat to human health, possibly even more so children. Personal exposure of 86 schoolchildren ambient air levels were measured simultaneously. The potential risks also investigated. results revealed highest personal exposures school children residing close oil refinery. average level benzene comparable these which indicated large impact outdoor pollution on exposure. non-cancer for within acceptable limits (HQ<1), meaning no adverse effects expected result exposures. Despite was lower than daily guideline value, estimate cancer risk showed lifetime not negligible therefore monitoring measure should be taken into account preserve health
