Abstract The paper presents an original research regarding the risk for human health in the area of Ploiesti city using SADA software - Spatial Analysis and Decision Assistance. Due to the high level of toxicity, international legislation provides the list of PCBs compounds to be monitored: PCB28, 52, 101, 118, 138, 153, 180. Sample collection was made in 22 points including public green gardens, residential areas, roadsides and industrial areas. The chemical analyses were conducted in the Laboratory of National Research and Development Institute for Soil Science, Agro-Chemistry and Environment from Bucharest, according to an own analytical method adapted after EPA. According to the Romanian standards, PCBs were elevated across industrial regions near urban and industrial sources. The concentrations of PCBs overcome the normal values in the most sampling points and the area presents a potential of risk for people. Local authorities should address the human health threats from urban and industrial soils in Ploiesti city.
摘要本文采用SADA软件空间分析与决策辅助系统(Spatial Analysis and Decision Assistance)对普洛耶斯蒂市地区的人类健康风险进行了原创性研究。由于高毒性，国际立法提供了需要监测的多氯联苯化合物清单:PCB28、52、101、118、138、153、180。样本采集地点包括公共绿地、住宅区、路边和工业区等22个地点。化学分析在布加勒斯特国家土壤科学、农业化学和环境研究与发展研究所实验室进行，根据EPA调整的自己的分析方法。根据罗马尼亚的标准，多氯联苯在城市和工业污染源附近的工业区都有升高。多氯联苯的浓度在大多数采样点超过正常值，该地区对人类存在潜在风险。地方当局应解决普洛耶斯蒂市城市和工业土壤对人类健康的威胁。

Abstract In the last decade there is an increased interest in selecting photosynthetic microorganisms with higher lipid content useful for biotechnological applications. In this paper we present our original results concerning: i) the selection of naturally occurring photosynthetic microorganisms with higher lipid content; ii) the use of these isolates as biological material subject of randomly induced mutagenesis; iii) selection by iodine vapour method of clones with decreased polysaccharides content and expected higher lipid content) as well as iv) genetic analysis of most promising strains in order to check the if they are true mutants or not. The results thus obtained argue the importance of the selection of naturally occurring photosynthetic microorganisms with higher lipid content as well as the use of random mutagenesis as a valuable tool to improve the genetic diversity of photosynthetic microorganisms in order to increase their ability to synthesize lipids for further biodiesel production and/or omega 3 or 6 production.

Abstract The paper aims to evaluate the potential of using aerial images captured from UAV’s, when compared with satellite images, for the purpose of monitoring rapeseed cultures. For this, a comparison is presented; two modern methods of gathering and processing images with the purpose of estimating the rapeseed culture yields, in contrast with the classic method. For this purpose, we use professional equipment to gather images, GPS RTK to provide advanced precision, as well as software such as Precision Flight to plan the flight routes, Precision Mapper to construct the orthophoto, custom made Python programs and LeoWorks to process and classify the resulting images.
