RESUMO
OBJECT IVE To provide reference for relevant decision-makers to formulate policies to guide the transfer of pharmaceutical industry. METHODS Using the statistical data from 2000 to 2019，taking industrial transfer index as index ，on the basis of 4 regions，our country was divided into 8 comprehensive economic areas ：the eastern coastal area ，the southern coastal area，the northern coastal area ，the middle reaches of the Yellow River area ，the middle reaches of the Yangtze River area ，the northeast area ，the southwest area and the northwest area. The regional characteristics and regularity of China ’s pharmaceutical industrial transfer were discussed in terms of space and time. RESULTS & CONCLUSIONS From 2004 to 2019，among the 31 provinces，pharmaceutical industry was transferred in 19 provinces，including Jilin ，Shandong，Henan and Gansu ，accounting for 61.3％；pharmaceutical industry was transferred out in 12 provinces，including Hebei ，Beijing，Xinjiang and Hubei ，accounting for 38.7％. There were 12 provinces whose absolute average values of industrial transfer index were greater than 0.2，indicating that China’s pharmaceutical industry had undergone large-scale migration among provinces ，and the scale of pharmaceutical industrial transfer varied significantly among provinces. From the perspective of regional distribution ，4 pharmaceutical industrial transfer-in centers had been formed in China ，the eastern coastal area ，the northeast area ，the middle reaches of the Yangtze River area and the southern coastal area ；industrial transfer followed the location selection mode from within areas to between areas. From the perspective of time change trend ，there was a phenomenon of gradient deviation in the transfer of pharmaceutical industry in various areas of China ，and there are 5 evolution types ，mainly including “up and down fluctuation ”，“first decrease and then increase”，“first increase and then decrease ”；the transfer of pharmaceutical industry was active in most areas ，and the transfer path remained relatively stable. In some areas ，the roles of transfer-out place and transfer-in place had been exchanged. According to the scale and trend of industrial transfer ，each area should formulate guiding policies to realize the coordinated development of inter-regional pharmaceutical industry.
RESUMO
By using microwave extraction, a GC/MS method was developed for the determination of polycyclic aromatic hydrocarbons ( PAHs) content in soil which is around the discharge ditch of oily wastewater, and a correlation analysis of the content of organic matter in soil was carried out. The results showed that PAHs in the surface soil pollution were mainly from 2 to 4 rings of low molecular PAHs, and the PAHs with high molecular were not detected. Each sampling point belongs to slight or moderate pollution and the overall assessment is moderate pollution, which is middle and low lever in comparison with soil data of central regions. The origin may be the low molecular PAHs of oil pollution along with the atmospheric transmission, but it cannot be completely excluded the possibility of fuel combustion pollution. No obvious correlation was found between the content of polycyclic aromatic hydrocarbons and organic matter.
