With China's rapid economic development, the reduction in arable land has emerged as one of the most prominent problems in the nation. The long-term dynamic monitoring of arable land quality is important for protecting arable land resources. An efficient practice is to select optimal sample points while obtaining accurate predictions. To this end, the(More)
A multimedia fugacity model with spatially resolved environmental phases at an urban scale was developed. In this model, the key parameter, organic matter, was replaced with black carbon (BC) and applied to simulate the distributions of phenanthrene (Phe), pyrene (Pyr) and benzo[α]pyrene (BaP) in Nanjing, China. Based on the estimated emissions and measured(More)
The soluble organic fractions (SOF) in diesel exhaust particulates have been extracted with ultrasonic separator and analyzed by gas chromatography/mass spectrometry (GC/ MS). The GC/MS conditions were as follows: an HP SE-50 capillary column (30 m x 0.2 mm i. d. x 0.2 microm); temperature programming started at 100 degrees C, holding for 2.0 min, then(More)
