The Relationship between the Concentrations of Benzene from Measurements and the CALINE - 4 Models

Abstract
A study of the relationship between the concentration of benzene obtained from measurements and the CALINE - 4 model and to study the relationship between the concentration of benzene obtained from measurements and the CALINE - 4 model. The concentration of benzene were collected in rush hour from 4.00 - 5.00 pm.All samples were collected by a Coconut shell charcoal tube and analyzed by Gas Chromatography. The benzene concentration from the actual measurement was in the range of 0.0008 - 0.0084 mg/M3, with an average of 0.0038 ± 0.0028 mg/M3. The benzene concentration from CALINE-4 was in the range of 0.0093 - 0.1533 mg/M3, with an average of 0.0640 ± 0.0506 mg/M3, The benzene concentration of was measured and the CALINE - 4 assessment not difference at level of 0.01 (Sig equal to 0.000 <0.01) and correlated well with a very high correlation coefficient (R) is equal to 0.9647 Index Term - Benzene, Caline – 4, Air Pollution
