The concentration and composition of PAHs emitted from biomass cooking fuel were characterized in a rural non-smoking household in northern China. Twenty-two parent PAHs (pPAHs), 12 nitro-PAHs (nPAHs), and 4 oxy-PAHs (oPAHs) were measured in the kitchen, bedroom, and outdoors during both summer and winter. The most severe contamination occurred in the kitchen in the winter, where the daily mean...
In the title mol-ecular salt, C(16)H(13)N(2)OS(+)·HSO(4) (-), the thia-zolo[3,2-a]benzimidazolium ring system is roughly planar [maximum deviation = 0.046 (3) Å] and makes a dihedral angle of 58.22 (11)° with the benzene ring. The meth-oxy group is almost coplanar with its attached benzene ring [C(meth-yl)-O-C-C = -1.6 (5)°]. In the crystal, the cation is linked to the anion by a bifurcated N-H...
a conductance study of the interaction between cs+, rb+, nh4+, k+, t1+ and ag+ ions and18-crown-6 (18c6), benzo-18-crown-6 (b18c6), dicyclohexyl-18-crown-6 (dc18c6),dicyclohexyl-24-crown-8 (dc24c8), dibenzo-24-crown-8 (db24c8) in different binarymixtures of acetonitrile (an) with dimethylsulfoxide (dmso) and dimethylformamide (dmf)at 25 °c has been carried out. formation constants of the result...
The environment is heavily populated with polycyclic aromatic hydrocarbons (PAHs), which are dangerous to human health. Degradation and cleaning of PAH chemicals from water soil regions crucial due their chemical biological impacts persistent nature. In this study, we found that a very efficient bacterial consortium A-LOBP-19A+LOP-9 (99.62%) for benzo[a]pyrene up 1000ppm B-LOP-9 +GWP-2 (93.8%) ...
Mutagenic activity of nine nitro derivatives of benzanthrone, namely 1-nitro-, 2-nitro-, 3-nitro-, 9-nitro-, 11-nitro-, 1,9-dinitro-, 3,9-dinitro-, 3,11-dinitro- and 3,9,11-trinitrobenzanthrone were tested with Salmonella strains TA98, TA100, YG1021 and YG1024 in both the presence and absence of an S9 mix. Each compound exhibited mutagenic activity with all the strains. Among these nine isomers...
In the title compound, C(15)H(13)NO(3), the dihedral angle between the two aromatic rings is 79.25 (16)°.
در این پروژه، روش کلی سنتز دو سری از کمپلکس های سیکلومتاله شده ارگانو پلاتین که شامل لیگاند های 2-فنیل پیریدین (h-ppy) و benzo[h]quinolone می باشد ارائه شده است که از واکنش 2 اکی مولار از لیگاند های benzo[h]quinoline (bhq) وc^n= 2-phenylpyridine (ppy) در استون با دایمر cis,cis-[pt2me4(µ-sme2)2]، کمپلکس های [pt(ppy)(sme2)me]، 1 و [pt(bhq)(sme2)me]، 2 را می دهد. زمانی که کمپلکس های 1 و 2 با 1 اکی...
In this study, PAHs and their transformed PAH products (TPPs) in road dust were subjected to UV driven photolysis, then extracted using simultaneous pressurized fluid extraction, analysed Shimadzu Triple Quadrupole GC/MS. The results of the analysis used investigate robustness reliability 14 existing diagnostic ratios (DRs) two newly proposed molecular DRs that are relevant for characterizing s...
Assistant dopants with reduced Dexter energy transfer rates were designed by replacing the donor moiety of 2,3,5,6-tetra(9 H -carbazol-9-yl)terephthalonitrile (4CzTPN) 5 -benzo[4,5]thieno[3,2- c ]carbazole (BTCz).
