Study of black Carbon levels in city centers and industrial centers in Jordan

الملخص EN

Light absorption coefficients of black carbon (Babs ) were measured at several urban and industrial locations in Jordan during the summer of 2007 and the winter of 2008 using the photoacoustic instrument at a wavelength of 870 nm.

Black carbon mass concentration (BC) was calculated using Babs .

Black carbon levels at urban locations in the summer of 2007 were higher than those obtained at industrial centers.

Zarqa had the highest value of BC in summer (29.24μg/m3) and in winter (13.27μg/m3).

Ibbeen and Irbid city center had relatively high values of BC in winter: 11.75μg/m3 and 12.48μg/m3, respectively.
