Abstract We report results of an interdisciplinary project devoted to the 26 km‐diameter Ries crater and genesis suevite. Recent laboratory analyses “crater suevite” occurring within central basin “outer on top continuous ejecta blanket, as well data accumulated during past 50 years, are interpreted boundary conditions imposed by a comprehensive new effort model formation its deposits computer code calculations (Artemieva et al. 2013). The properties suevite considered all scales from...
Abstract
1. Pyrene metabolite g.l.c. profiles were recorded and metabolites identified by mass spectrometry.2. is metabolized liver microsomes of untreated rats to 1-hydroxypyrene, 4,5-dihydroxy-4,5-dihydropyrene, two different diphenols a triol, tentatively as 1,4,5-trihydroxy-4,5-dihydropyrene.3. Pretreatment with phenobarbital or polychlorinated biphenyls favours oxidation at the K-region, whereas cytochrome P-448 inducers stimulate non-K-region pyrene.4. 1-Hydroxypyrene does not inhibit pyrene...
Eutrophication due to excessive nutrient inputs is a major threat coastal ecosystems worldwide, causing harmful algae blooms, seagrass loss and hypoxia. Decisions combat eutrophication in the North Sea were made 1980s. Despite significant improvements during recent decades, high nitrogen loads resulting problems remain. In this study, long-term changes Elbe Estuary (Germany) characterized based on data provided by River Basin Community from 1985 2019. Additionally, surface water samples...

Abstract Urinary PAH-metabolite excretion by non-exposed volunteers, temporarily living on a PAH-poor and PAH-rich diet, respectively, as well occupationally PAH-exposed coke plant workers road has been studied. Significant differences in the amount of metabolites excreted urine were detected; ratio various was also found to be different. The mass per liter from phenanthrene for unexposed volunteers about 3.5μg/1, 70μg/l 35 μg/l. For chrysene values 0.03 μg/1 2.5 μg/l 0.09μg/l, total...
Treatment of mouse skin with coal tar is known to initiate tumour formation, the carcinogenic activity associated mainly polycyclic aromatic hydrocarbons (PAHs). A sample pharmaceutical was analysed by gas chromatography and 19 major PAHs were identified. 32P-postlabelling analysis used characterize those that are responsible for DNA binding and, inference, its biological activity. grouped according their reported activities applied as mixtures skin. Group contained all PAHs, group B seven...
