Comparison between the Chinese EIA Guidelines for Air Dispersion Modelling and the Advanced Air Dispersion Model ADMS 总被引:1,自引:0,他引:1
1 INTRODUCTION According to the Environmental Protection Law of P.R. China, and the Environmental Protection Management Method on Construction Projects the Technical Guidelines for Environmental Impact Assessment (EIA) (HJ/T 2.1~2. 3-93) have defined how environmental impact assessment should be carried out for construction projects, in terms of the general principle, methodology, contents and requirements. Technical Guidelines for Environmental Impact Assessment on the Atmosphe… 相似文献

Several physiologically based extraction procedures have been proposed to estimate the fraction of the potentially toxic element
content that would be bioaccessible in the human gastro-intestinal tract following accidental ingestion of soil. Many of these
procedures are complex, they have been applied to a very limited range of soils, and most work has focussed on arsenic and
lead. In the present study, a simplified, two-stage extraction, simulating the human stomach and intestine, was developed
and applied to urban soil samples from ten public-access areas in the City of Torino, Italy. The human oral bioaccessibility
of chromium, copper, nickel, lead and zinc was estimated. Lead and zinc bioaccessibilities were found to be higher in the
stomach, but chromium was more bioaccessible in the intestine. Analyte concentrations were higher in roadside soils than in
soils from parks. A higher proportion of the soil metal content was found in bioaccessible forms at roadsides than in parks.
Comparison of the current findings with results of earlier work involving sequential extraction of the same soils indicated
that the sequential procedure gave a relative, but not an absolute, indication of bioaccessibility. Calculations based on
the bioaccessible analyte concentrations suggest that ingestion of only 2–3 g of some of the roadside soil samples from Torino
could deliver the tolerable daily oral intake of chromium, nickel and lead to a 20-kg child. The developed procedure is useful
for preliminary screening of soils and prediction of whether their bioaccessible metal contents are likely to pose a risk
to human health. 相似文献

Relational thinking has recently gained increasing prominence across academic disciplines in an attempt to understand complex phenomena in terms of constitutive processes and relations. Interdisciplinary fields of study, such as science and technology studies (STS), the environmental humanities, and the posthumanities, for example, have started to reformulate academic understanding of nature-cultures based on relational thinking. Although the sustainability crisis serves as a contemporary backdrop and in fact calls for such innovative forms of interdisciplinary scholarship, the field of sustainability research has not yet tapped into the rich possibilities offered by relational thinking. Against this background, the purpose of this paper is to identify relational approaches to ontology, epistemology, and ethics which are relevant to sustainability research. More specifically, we analyze how relational approaches have been understood and conceptualized across a broad range of disciplines and contexts relevant to sustainability to identify and harness connections and contributions for future sustainability-related work. Our results highlight common themes and patterns across relational approaches, helping to identify and characterize a relational paradigm within sustainability research. On this basis, we conclude with a call to action for sustainability researchers to co-develop a research agenda for advancing this relational paradigm within sustainability research, practice, and education. 相似文献

Cysts located on the tongue are rare and usually diagnosed in childhood. Here we report on the prenatal diagnosis of an unusual cystic malformation of the tongue with heterotopic intestinal tissue explored by prenatal ultrasound, magnetic resonance imaging and on its surgical treatment and histological examination. The prenatal differential diagnoses as well as perinatal management of cystic lesions of the tongue are reviewed. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献
