The Dynamic Analysis of Benzo [a]pyrene in Corn Straw
Abstract:
Samples of corn straw, soils and environmental water were collected, and Benzo[a]pyrene (B[a]P) in samples was detected by means of GC/MS. Its levels in atmosphere, soils and environmental water are ranged from 17.6 to 18.4, 0.2 to 2.7 and 5.1 to 5.4μg/kg, respectively. To B[a]P in corn straw, the contribution of the atmosphere is dominant. B[a]P levels in soils where corn straw burned was higher than that where such burning not occurred, and higher levels of B[a]P in soils of suburban roadside and lower level in rural roadside were observed. B[a]P was detected in river water and rainwater, but it was not detected in groundwater. Although soil and environmental water contributed B[a]P to corn through root uptake, that will be very limited importance. For GC/MS, selected monitoring of molecular ions for target analyte and standard was performed instead of full scanning analysis.
