摘要：OBJECTIVE： To design a combined dynamic inhalation device for testing the toxicity induced by moxa smoking. METHODS： The new apparatus （Patent No. 201120101911.5） includes air renewal and recycling systems, a gas generating device, a gas control unit, and a device to measure and control tem- perature and humidity. Sprague-dawley rats were tested for acute and sub-chronic toxicity after exposure to moxa-burning ***： The new apparatus （Patent No. 201120101911.5） includes air renewal and recycling systems, a gas generating device, a gas control unit, and a device to measure and control tem- perature and humidity. Sprague-dawley rats were tested for acute and sub-chronic toxicity after exposure to moxa-burning ***： We found an LQ0 of 1.2× 10^4 mg/m^3 in the acute toxicity assays. In sub-chronic toxicity tests the organ coefficients studied showed no sig-nificant differences within rats groups of the same gender after treatment with moxa smoke or a month of recovery. However, mean gray degree of lung 70 heat shock protein （HSP70） was significantly elevated in the high dose group in comparison with the low dose group （P 〈 0.05）, mean gray degree, mean optical density, gross area of HSP70 in other organs and caspase-9 parameters showed no significant differences between ***： These results suggest that moxa smoke had no overt toxicity in rats. This work pro- vides evidence and reference for the design of dy- namic inhalation exposure systems.

摘要：A new index, i.e., the periphery representation of the projection of a molecule from 3D space to a 2D plane is described. The results, correlation with toxicity of substituted nitrobenzenes, obtained by using periphery descrip-tors are much better than that obtained by using the areas (i.e., shadows) of projections of the compounds. Even better results were achieved by using the combination of periphery descriptors and the projections areas as well as the indicated variable K reflecting the action of group NO2 position on the benzene ring.

摘要：Urban highway runoff samples from seventeen rainfall events were collected in Shanghai in 2011. The concentrations of ten heavy metals and sixteen polycyclic aromatic hydrocarbons PAHs are analyzed. The results show that the heavy metal concentrations range within 0.50 to 51.80 As 0 to 20.80 Se 13.67 to 445.80 Zn 0 to 44.20 Pb 0 to 15.80 Ni 39.58 to 264.20 Fe 0 to 253.00 Mn 0 to 8.20 Cr 0 to 124.20 Cu and 159.83 to 536.40 μg/L Al . Se Pb Mn and Al concentrations in most samples exceed their corresponding criterion continuous concentrations CCCs while Zn and Cu concentrations exceed their criterion maximum concentrations CMCs .The concentrations ofΣPAHs range within 37.25 to 114.57 ng/L and concentrations of PAHs are all below their corresponding *** Zn and ΣPAHs show the first flush phenomenon. Analysis results of the modified Nemerow index method NIM indicate that runoff from eight rainfall events may have very strong biological toxicity effects four have strong effects three have moderate effects and only two have insignificant *** it is concluded that urban highway runoff is a significant pollution source to aquatic ecosystems and needs immediate purification.
