Pools and fluxes of mercury and methylmercury in two forested catchments in Germany

Mercury (Hg) and methylmercury (CH3Hg+) are global pollutants, but little information is available on rates of atmospheric input, distribution and mobility in soils and catchments of central Europe. The objectives of this study were to investigate input and output fluxes of these compounds in a deciduous and a coniferous catchment in NE Bavaria (Germany), and to estimate pools and mobility of total Hg (Hgtot) and CH3Hg+ at the catchment scale. Bulk precipitation, throughfall, litterfall and runoff were collected biweekly from April 1998 to April 1999. Several soil profiles were sampled to estimate pools of Hg compounds in the catchments. In both catchments highest contents of Hgtot were found in the Oa layer of the forest floor (up to 500 ng g(-1)) and the soil storage of Hgtot calculated for a soil depth of 60 cm was approximately 890 g ha(-1) in the coniferous and 190 g ha(-1) in the deciduous catchment. Highest contents of CH3Hg+ in upland soils were observed in the Oi layer of the forest floor, and soil storage of CH3Hg+ was 4.35 g ha(-1) in the coniferous and 0.59 g ha(-1) in the deciduous catchment. The annual total deposition of Hgtot (total deposition not measured directly but calculated from throughfall and litterfall) was 541 mg ha(-1) year(-1) in the coniferous and 618 mg ha(-1) year(-1) in the deciduous catchment. Total deposition rates of CH3Hg+ were 3.5 and 2.6 mg ha(-1) year(-1). The contribution of litterfall to the total deposition of Hgtot and CH3Hg+ was 55% in the deciduous catchment. In the coniferous catchment, the contribution of litterfall to total deposition was only 29% for Hgtot, but 55% for CH3Hg+. By far the largest proportion of the deposited CH3Hg+ and Hgtot remained in the catchments (85% in the coniferous, 95% in the deciduous). As compared to remote Swedish catchments, deposition and output via runoff of Hgtot, were higher, but deposition and output of CH3Hg+ were lower in our catchments. In contrast to other studies, the annual budget revealed no differences in the mobility between the two species at the catchment scale. However, temporal patterns of the runoff fluxes and converse gradients of CH3Hg+ and Hgtot contents in the forest floor indicated differences in mobility on shorter time scales.     

Prolift材质医用网片在家兔体内的生物相容性及缩变的实验研究

目的探讨Prolift材质医用网片在动物体内的生物相容性及面积缩变度。方法将6只新西兰家兔按随机数字表法分为3组：A组、B组和C组,每组2只。每只家兔腹部皮下放置10 mm×40 mm Prolift材质医用网片10片。3组家兔术后均采用氟哌酸50 mg.d-1加入饲料中口服,抗感染3 d。A组中1只家兔出现感染为A1组,1只未感染的家兔为A2组;B、C 2组家兔均未出现感染。A组术后第14天处死家兔,B组术后第30天处死家兔,C组术后第90天处死家兔,各组家兔分别取出Prolift材质医用网片及肌肉组织,以家兔自身的皮下组织及肌肉组织作为对照组。用游标卡尺测量Prolift材质医用网片的长、宽值,计算面积及Prolift材质医用网片面积缩变度。同时行组织切片,在光学显微镜下观察各组家兔的炎症反应、纤维组织囊壁形成情况。结果 A1组家兔术后第3天出现植入Prolift材质医用网片部位感染,各组家兔均无血清肿、侵蚀、暴露及排斥反应等。A1、A2、B、C 4组家兔Prolift材质医用网片面积缩变度分别为（21.84±0.05）%、（3.13±0.03）%、（2.30±0.03）%、（2.50±0.03）%,A1组家兔Prolift材质医用网片面积缩变度和处死后的网片面积与A2组比较差异均有统计学意义（均P〈0.05）,家兔Prolift材质医用网片面积缩变度和处死后的网片面积A2组、B组、C组之间比较差异均无统计学意义（均P〉0.05）。A2、B、C 3组家兔炎症反应分级分别为Ⅲ级、Ⅱ级、〈Ⅰ级,纤维组织囊壁形成分别为Ⅲ级、Ⅱ级、〈Ⅰ级。结论 Prolift材质医用网片植入家兔体内后具有良好的抗缩变性能和生物相容性,但感染可能是引起网片缩变的重要因素。

Occurrence of acidic pharmaceuticals in raw and treated sewages and in receiving waters

The occurrence of five acidic pharmaceuticals, ibuprofen, naproxen, ketoprofen, diclofenac and bezafibrate, in seven different sewage treatment plants (STP) and three receiving waters were determined. The analytical procedure included solid phase extraction, liquid chromatographic separation and detection by a triple-quadrupole mass spectrometer. The studied pharmaceuticals were found in all the STPs. The pattern of the occurrence of individual compounds was the same in every STP and matched the consumption figures reported in the literature. Ibuprofen is the most used pharmaceutical in Finland and was accordingly found to be the most abundant compound in the raw sewage. In the treatment processes, the highest removal rate was observed for ibuprofen and the lowest for diclofenac, 92%+/-8% and 26%+/-17%, respectively. Due to the incomplete removal in the STPs, the pharmaceuticals were found in rivers at the discharge points of the STP effluents. Downstream from the discharge points, the concentrations decreased significantly mainly due to dilution in the river water. The risk to the aquatic environment was estimated by a ratio of measured environmental concentration (MEC) and predicted no-effect concentration (PNEC). At the concentrations the compounds were found in the surface waters, they should not pose risk for the aquatic environment. However, at dry seasons and/or during malfunctions of STPs, ibuprofen could be associated with a risk in small river systems.

Assessment of the performance of organic and mineral-based insulation products used in exterior walls and attics in dwellings

The assessment of the performance of organic and mineral-based insulation products used in exterior walls and attics in traditional Danish housing estate was evaluated. The assessment covered the ability of the materials to be handled on site as well as measurements of the performance of the materials once installed and exposed to normal use of the dwellings and Danish weather conditions over a 2-year period. Evaluations were based on, on-site observations, thermographic observations and measurements of temperature and moisture conditions within the different materials used. Eight different products were used for thermal insulation including six organic and two mineral fibre materials. Loose-fill material and predefined fixed-shape products were used. The eight different products were installed in 16 dwellings, two neighbouring dwellings were insulated with each product. Exterior walls were constructed without PE vapour barriers while ceilings were constructed with PE vapour barriers.

Social relationships and patterns of use in urban public spaces in China and the United Kingdom

Public spaces are social places that enhance social life and foster social interactions. However, there is a lack of analysis of the patterns of use by people in various types of social relationships. Observational data on four public spaces in Suzhou, China, and Sheffield, UK, assessed users' personal characteristics, activities and spatial occupancies in public spaces. Site factors were not related to personal characteristics, but age and group size were culturally different. Activities and spatial occupancies differed between unaccompanied and accompanied users. Compared to single users, users in groups tended to participate in multiple activities at once, and their activities included more interactions. Single users' spatial distributions conformed to the edge effect, but users in groups were evenly distributed in the spaces. Three types of social relationships were defined: Intimate Pair, Intimate Group and Social Group. Intimate Pairs were most likely to use mobile phones and use private spaces, Intimate Groups were most likely to be talking and sitting and to use park amenities, and Social Groups were most likely to be playing games and relaxing in spacious open areas. Regarding spatial occupancy, Intimate Pairs and Social Groups were most likely to use the middle and peripheral regions, and the Intimate Groups tended to be evenly distributed in the spaces. The results of this study stress the importance of designing public spaces for the types of users expected to use the spaces and to consider various types of social relationship groups.
