Uptake of 137Cs was measured in different agricultural plant species (beans, lettuce, barley and ryegrass) grown in 5 undisturbed soil monoliths covering major European soil types. The first cultivation was made three years after soil contamination and plants were grown during 3 successive years. The plant–soil 137Cs transfer factors varied maximally 12-fold among soils and 35-fold among species when grown on the same soil. Single correlations between transfer factors and soil properties were found, but they varied widely with plant type and can hardly be used as a predictive tool because of the few soils used. The variation of 137Cs concentrations in plants among soils was related to differences in soil solution 137Cs and K concentrations, consistent with previous observations in hydroponics and pot trials. Absolute values of transfer factors could not be predicted based on a model validated for pot trials. The 137Cs activity concentration in soil solution decreased significantly (11- to 250-fold) for most soils in the 1997–1999 period and is partly explained by decreasing K in soil solution. Transfer factors of lettuce showed both increasing and decreasing trends between 2 consecutive years depending on soil type. The trends could be explained by the variation in 137Cs and K concentrations in soil solution. It is concluded that differences in 137Cs transfer factors among soils and trends in transfer factors as a function of time can be explained from soil solution composition, as shown previously for pot trials, although absolute values of transfer factors could not be predicted. 相似文献

Is phytoremediation a sustainable and reliable approach to clean-up contaminated water and soil in Alpine areas? 总被引:1,自引:0,他引:1

Background, aim and scope
Phytoremediation does exploit natural plant physiological processes and can be used to decontaminate agricultural soils, industrial sites, brownfields, sediments and water containing inorganic and organic pollutants or to improve food chain safety by phytostabilisation of toxic elements. It is a low-cost and environment friendly technology targetting removal, degradation or immobilisation of contaminants. The aim of the present review is to highlight some recent advances in phytoremediation in the Alpine context. 相似文献36.

Animal husbandry and labour migration are important livelihood strategies for a large proportion of the rural population in developing countries. Up to now, the two strategies have usually been studied by looking at either one or the other; their interlinkages have rarely been examined. Based on a case study in rural Kyrgyzstan, the aim of this paper is to explore the links between animal husbandry and labour migration. Results show that for most rural households, livestock is crucial yet not sufficient to make a living. Therefore, many people diversify their income sources by migrating to work elsewhere. This generates cash for daily expenses and the acquisition of new livestock, but also leads to an absence of workforce in households. Yet since remittances usually exceed the expenses for hiring additional workforce, most people consider migration profitable. From a socio‐economic point of view, migration and animal husbandry can thus be considered important complementary livelihood strategies for the rural Kyrgyz population, at least for the time being. In the long term, however, the failure of young migrants to return to rural places and their settlement in urban areas might also cause remittance dependency and lead to an increasing lack of qualified labour. From an environmental point of view, the investment of remittances into animal husbandry poses challenges to sustainable pasture management. Increasing livestock numbers in rural areas raise pressure on pasture resources. Since most people consider animal husbandry their main future prospect while continuing to use pastures in a fairly unsustainable way, this may further exacerbate the over‐utilization of pastures in future. 相似文献

Soil and water quality is greatly affected by environmental pollution due to the increasing trend of urbanization and industrialization. In many developing countries, including Pakistan, the situation is more alarming as no preventive measures are still taken to tackle the problem. Although in developed countries, many techniques are used to remediate the environment including phytoremediation. It is the most eco-friendly technique in which plants are used to remove pollutants from the environment. Pakistan has also a great diversity of plants which could be used for the remediation of environmental pollutants. To our knowledge, few studies from Pakistan were reported about the use of flora for phytoremediation. According to recent literature, 50 plant species from Pakistan are studied for remediation purposes. In this review, the potential of different plant species for phytoremediation from Pakistan has been discussed along with their comparison to other countries to relate future perspectives. 相似文献

IntroductionWe wished to determine the extent to which number of passengers, driver age, and sex were associated with aggressive driving actions (ADAs) in young drivers involved in a fatal crash.MethodsWe used U.S. fatal-crash data from Fatality Analysis Reporting System (FARS), 1991 –2008. Proxy measures of aggressive driving included ADA presence and speed differential (posted speed limit minus estimated travel speed). We examined the odds of an ADA and speed differential in young drivers (aged 16 to 25) by passenger status.ResultsCompared to driving alone young drivers (aged 16) had increased odds of an ADA between 14% (OR: 1.14; 95% CI: 1.07; 1.22) and 95% (OR: 1.95; 95% CI: 1.40; 2.74) when accompanied by one and five passengers, respectively. Further, carrying a higher number of passengers was a stronger predictor of speeding in younger drivers.ConclusionsThis study supports the use of graduated licensing approaches. Specifically, developing interventions to reduce aggressive driving appear imperative.Impact on IndustryWhile the results of our study support the use of graduated licensing approaches there is room for improvement. Our study indicates that tackling impaired driving is not sufficient to drastically reduce aggressive driving among the youngest drivers. Further research on young drivers is required to understand the influence of peers and the role of gender on driving behavior. Strategies to reduce aggressive driving behaviors among the youngest drivers may not only prevent crashes during their early driving careers but may also translate into a reduced crash risk over their lifetime. 相似文献
