Total petroleum hydrocarbons (TPHs) are hazardous to human health, and some are potentially toxic to humans . Some TPH compounds such as benzene are carcinogenic, while others such as gasoline are listed by the International Agency for Research on Cancer (IARC) as known carcinogens when occupationally encountered during routine use [ 13 ].

Therefore, when SM is too high, nodulization becomes weak and clinkerization reaction (C3S formation) rate slows down, kiln becomes dusty and difficult to operate. While as when SM is too low, more melt is formed in kiln, issues like thick kiln coating, kiln melting, snowman formation in cooler are more prone. Normal range of SM is 2.3-2.7.
