We developed an air pollutant emission inventory for marine vessels in the Shanghai Port in 2003. We estimated emissions under cruising and maneuvering conditions based on two categories of vessels: (1) vessels in the Outer Port, which enter the area following notification of the Shanghai Maritime Safety Administration, a division of the Ministry of(More)
Analyses of diurnal patterns of PM10 in the downtown of Pudong, Shanghai have been performed in this study at different daily ozone maximum concentrations (O(3,max)) from May to October, 2010. In order to evaluate secondary aerosol formation at different ozone levels, CO was used as a tracer for primary aerosol, and 0(3, max) was used as an index for(More)

In the title compound, C28H29FN3O3PS, the pyrimidine ring is oriented at a dihedral angle of 50.9 (2)° with respect to the floro-benzene ring, while the two phenyl rings bonding to the same P atom are twisted with respect to each other, making a dihedral angle of 62.2 (2)°. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯F hydrogen bonds into a(More)

The asymmetric unit of the title compound, C(20)H(15)N(2)P, contains two independent mol-ecules with similar structures. The 1,5-naphthyridine ring system is nearly planar, with maximum deviations of 0.010 (3) and 0.012 (3) Å; its mean plane is oriented with respect to the two phenyl rings at 79.69 (12) and 84.00 (10)° in one mol-ecule, and at 74.25 (12)(More)
The concentration, speciation and chemical reactivity of ambient volatile organic compounds (VOCs) in shanghai city were analyzed and measured by using online gas chromatography with flame ionization detection systems (GC-FID) during a typical air pollution episode (from Oct. 30th to Nov. 2nd, 2010) and 55 kinds of VOCs were detected. The results show that(More)

In the title compound, C6H6ClN3O2, all non-H atoms are approximately coplanar [maximum deviation = 0.012 (4) Å]; an intra-molecular N-H⋯O hydrogen bond occurs between the amino group and the carbonyl group. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into supra-molecular chains propagated along [101].
