3.QUANTITATIVE ANALYSIS OF SOPORIFIC SEDATIVE DRUGS AND LOCAL ANESTHETIC DRUGS WITH UNIDENTICAL STANDARD SUBSTANCE BY GC AED
7.After its oral administration to human, the relative bioavailability of T was 103.45 % ±11.75%. Paired analysis indicated that T_max, C_max and AUC_0→t did notdiffer between T and R and both preparations were bioequivalent. ATX, the standard substance, was used to quantitate all the samples again and the results were as follows: one-compartment model;
8.The content of Pb,As,Cd,Cr of planting soil,vegetables and irrigated water in several producing base which has no environmental pollution was analyzed by AAS The RSD and recovery of this method is less than 7% and from 94% to 110% respectively The determined results of GBW 08302 soil standard substance are consistent with that of recommendation
10.Comparation of the result with the past surveys, the PSP content in the present survey was lower than in 1991, but was in the same level as in 2002. The PSP contents in the oysters in all 15 maricultural waters were lower than the limit standard for the toxic substance in the non-environmental pollution aquatic products, and also lower than the safety market limit set by the FAO.
