Total and extractable contents of trace metals in agricultural soils of the Valderas area, Spain

The surface horizons of four agricultural field soils (Mollic ustifluvents, Alfic Xerochrepts, Typic Palexeralfs, Typic Haploxeralfs) were sampled to determine the total copper, cobalt, molybdenum, zinc, chromium, nickel, selenium, cadmium, lead, mercury, lithium and strontium, and were also fractionated by an extraction procedure to estimate the quantities of these trace metals in soluble form. The extractants used were the following: 1.0 N NH4 OAc for lithium and strontium, 0.05 M Na2-EDTA for cadmium, copper, nickel and zinc, 2.5% (w/v) acetic acid for lead, 2.5% (w/v) acetic acid and 2% (w/v) dithizone for cobalt, 2% (w/v) diethyldithiocarbamate solution for selenium, 0.1 NHCl for chromium, and 0.5 NHCl for mercury. The total content of these twelve elements in the four field soils sampled were lower than the levels quoted in the literature, although for different geochemical systems. The percentage of the total element content in soluble form was (except for selenium) generally very low, averaging between 5.5 and 8% for copper, 1.6 and 2.5% for cobalt, 8 and 10% for molybdenum, 1.8 and 2.2% for zinc, 14.2 and 17.7% for chromium, 5.5 and 6.4% for nickel, 30 and 55% for selenium, 8 and 14% for cadmium, 3 and 3.6% for lead, 8.3 and 11% for mercury, 5 and 7% for lithium, and 4.4 and 5.7% for strontium, regardless of the soil type.

改革开放以来中国城市园林绿化行业 治理体系演进的回顾、思考与展望

治理体系和治理能力现代化是城市园林绿化行业在新时代必须面对的时代命题。改革开放40年来，行业基本形成了“政府主导、央地互馈、部门协同、企业主体、社团辅助、专家支持、公众参与”的多元主体治理格局；基本形成了以国家政策和行业政策为引领，法律法规体系、规划设计体系和督察监察制度为保障，园林城市创建活动为特色抓手，专业教育体系、专家咨询制度、科研创新体系和技术标准体系为支撑，国际行业交流交往活动为拓展的多元治理工具体系；并在治理意识、治理思路、顶层谋划、治理主体、治理工具等方面取得了一系列经验；市场经济发展和社会主要矛盾变迁、国家治理体系发展演进、城市化进程、社会结构及其文化特征变迁是推动和影响行业治理体系演进的重要驱动力量。当前行业治理存在治理思维尚未全面建立、目标和思路尚不清晰、体系架构尚不完善、行业主管部门作为关键治理主体日渐式微、治理工具和手段不多等问题，据此从治理意识、战略视角、主体架构、顶层谋划、工具体系5个方面提出建议。     

Determination of selected trace elements in herbs and their infusions

The following macro- and microelements were determined in the leaf of peppermint (Mentha piperitae folium) and nettle (Urticae folium) (as tea bags) and in their infusions: As, Ba, Ca, Cd, Co, Cr, Cu, Fe, I, Li, Mg, Mn, Ni, Pb, Se, Sn, Sr, Ti, V and Zn. The determinations were performed using inductively coupled plasma mass spectrometry (ICP-MS) and atomic absorption spectrometry (AAS). From all the determined microelements the highest content found was that of iron, 244 and 107 mg/kg in the leaf of peppermint and nettle, respectively. However, the lowest content found was that of cobalt, 0.10 and 0.08 mg/kg for the leaf of mint and nettle, respectively. The most readily water eluting elements were strontium, selenium and iodine, the most difficult ones - barium and iron.

Trace elements in foods and meals consumed by students attending the faculty cafeteria

The content and intake of some trace elements (Pb, Cd, Ni, Hg, Cr) in meals, consumed by students attending the Faculty Cafeteria, were assessed. The study was carried out over 6 days of the 2nd week of February, 1993 and in three consecutive days of the second week of May. In those periods 10453 and 4055 students attended the cafeteria, respectively. After recording the ingredients and the preparation and cooking methods, some edible portions of foods and dishes were collected, homogenised, lyophilised and kept in polyethylene bottles until analysis. We found few differences in food content and dietary intake of some (Ni and Cr) but not all trace elements between February and May. Higher levels of Pb, Cd, Ni, Cr were present in bread (21.5+/-14.0, 5.6+/-0.02, 55.6+/-1.7 and 66.9+/-0.1 microg/100 g of edible portion, respectively), followed by meat, filled pasta and cheese, whereas lower values were observed in vegetables and fruit. The highest Hg content was recorded in the pasta group. Among the most frequently consumed foods and meals, the highest levels of P, Pb, Cr, Hg, Ni were found in bread, meat and pasta. The calculation of mean trace element intake, corrected for leftovers, showed pasta, bread and meat as the main sources of Pb, Cd, Ni, Hg and Cr over the two periods. The estimated potential tolerated weekly intake (PTWI) resulted high for Pb and Cd and low for Hg. Finally, a large variability in trace element content between raw and cooked foods was observed. These results give valuable information on trace element content of foods to be used for preparation of meals at the Faculty cafeteria in different seasons.     

NINE QUESTIONS TOWARD INFLUENCES OF EMERGING SCIENCE AND TECHNOLOGY ON URBAN ENVIRONMENT PLANNING AND DESIGN

There is no doubt that science and technology have progressed rapidly in the past decade and it is constantly challenging and refreshing people’s understanding of urban environment, human life, and even human nature itself. Meanwhile, its impact on urban environment planning and design should not be ignored and needs to be addressed promptly. The concept of science and technology is self-renewing and has no universal or authoritative definition. In a narrow sense, new science and technology may cover any new materials, technologies, and data invented or discovered by a human; in a broader sense, it might also study new behaviors, emotions, concepts, and philosophy arisen by new materials, technologies, and data. This article explores both positive and negative impacts of science and technology development on urban environment planning and design from nine aspects: image technology, image-tamed design, designers’ dilemma, virtual reality, personal mobile electronic devices, big data, human physical limits, public spaces, and nature. Instead of trying to provide definite answers to these questions, this article seeks to encourage readers’ to understand and think of these topics through a brief discussion.
