Introduction
In this study, we explore the identity of a range of polyfluorinated surfactants (PFS) used for food contact materials, primarily to impart oil and water repellency on paper and board. PFS are of interest, as they can be precursors of poly- and perfluorinated alkyl substances (PFAS), of which several are persistent and are found worldwide in human blood and in the environment. 相似文献672.

Introduction
In 2003, the Japan International Cooperation Agency carried out a development feasibility study of Klaipeda Seaport (Lithuania). The focus in this study was the evaluation of environmental impacts of the port expansion because it is located in an ecologically sensitive area. While the Japanese researchers focused on the environmental impact analysis, they did not provide unambiguous conclusions. The problems remained unresolved and required further, more detailed consideration and deeper analysis. 相似文献673.

Introduction
The present study was part of a comprehensive weight-of-evidence approach with the goal of identifying potential causes for the declines in fish populations, which have been observed during the past decades in the Upper Danube River. 相似文献674.
Background, aim, and scope
Ever since the discovery of the mutagenic properties of ionizing radiation, the possibility of birth sex odds shifts in exposed human populations was considered in the scientific community. Positive evidence, however weak, was obtained after the atomic bombing of Japan. We previously investigated trends in the sex odds before and after the Chernobyl Nuclear Power Plant accident. In a pilot study, combined data from the Czech Republic, Denmark, Finland, Germany, Hungary, Norway, Poland, and Sweden between 1982 and 1992 showed a downward trend in the sex odds and a significant jump in 1987, the year immediately after Chernobyl. Moreover, a significant positive association of the sex odds between 1986 and 1991 with Chernobyl fallout at the district level in Germany was observed. Both of these findings, temporality (effect after exposure) and dose response association, yield evidence of causality. The primary aim of this study was to investigate longer time periods (1950–2007) in all of Europe and in the USA with emphasis on the global atmospheric atomic bomb test fallout and on the Chernobyl accident. To obtain further evidence, we also analyze sex odds data near nuclear facilities in Germany and Switzerland. 相似文献675.

Background
Airborne fine particulates (PM 2.5) and its associated polycyclic aromatic hydrocarbons (PAHs) are reportedly hazardous in urban environment due to the presence of multiple emission sources. 相似文献676.

Purpose
We tested the genetic diversity in wild mice (Mus musculus domesticus) inhabiting the asbestos-polluted area as a model for the long-term mutagenic effect of asbestos. Hazardous effects of deposited asbestos persist in the environment because of low rate of fiber disintegration. The upper layers of the soil in the vicinity of a former asbestos factory are nearly “saturated” with asbestos fibers and dust. Natural populations of mice dwell in this area and are constantly exposed to asbestos fibers. 相似文献677.
Occurrence of perfluorinated organic acids in the North and Baltic seas. Part 1: distribution in sea water 总被引:1,自引:0,他引:1
Theobald N Caliebe C Gerwinski W Hühnerfuss H Lepom P 《Environmental science and pollution research international》2011,18(7):1057-1069
Purpose
Due to their high water solubilities and mobilities, persistent, polar perfluorinated compounds (PFCs) such as perfluorinated carboxylates and sulfonates are likely to end up in the oceans. In part 1 of this study, their distribution in North and Baltic Sea water is reported, being of special interest because these seas are surrounded by highly industrialized countries with high population densities. 相似文献678.

As an economically developing country, Turkey has very well operated integrated solid waste management applications structured
on modern facilities, besides over 2,000 scattered open dump areas in the country. Integrated waste management applications
seem eligible for the metropolitan cities like Istanbul and Izmit (Kocaeli). Attempts have not been encouraging for the scattered
regional settlements using central storage sites due to financial shortages and received rejections from nearby settlements.
Small-scale compact solid waste management systems with materials recycling and composting can be more suitable alternatives
in the small-scale regional settlements. The major constituents of municipal solid waste are organic in nature and approximately
a quarter of municipal solid waste is recyclable. Although paper, including cardboard, is the main constituent, the composition
of recyclable waste varies strongly by the source or the type of collection point. Solid wastes need primary treatment in
order to be suitable for incineration and composting. Turkey needs to give more emphasis on the usage of modern solid waste
removal technologies to overcome the overgrowing solid waste disposal problems. 相似文献

The circular economy has been developing rapidly in recent years in China. A legislative system has been created to provide
legal protection for the development of a circular economy, including a series of price and tax measures in the waste management
area. These measures form the basic foundation for promoting better waste management under the circular economic model. Many
challenges, however, remain. For instance, the legal system needs to incorporate more sophisticated science, and China lacks
key waste treatment technology that could support the further development of a circular economy. There is also a need to educate
the public about the concept of the circular economy and its benefits. Specific suggestions are made for the development and
implementation of the circular economic model. 相似文献

Since hydrogen is a renewable energy source, biohydrogen has been researched in recent years. However, data on hydrogen fermentation
by a leachate from a waste landfill as inoculum are scarce. We investigated hydrogen production using a leachate from an industrial
waste landfill in Kanagawa Prefecture. The results showed no methane gas production, and the leachate was a suitable inoculum
for hydrogen fermentation. The maximum H2 yield was 2.67 mol of H2 per mol of carbohydrate added, obtained at 30°C and an initial pH of 7. The acetate and butyrate production was significant
when the H2 yield was higher. Oxidation–reduction potential analysis of the culture suggested that hydrogen-producing bacteria in the
leachate were facultative anaerobic. Scanning electron microscope observations revealed that the hydrogen-producing bacteria
comprised bacilli about 2 μm in length. 相似文献
