Summary In many European agricultural landscapes, species richness is declining considerably. Studies performed at a very large spatial scale are helpful in understanding the reasons for this decline and as basis guiding policy. unique, large‐scale study of 25 landscapes seven countries, we investigated relationships between several taxa, links biodiversity landscape structure management. We estimated total vascular plants, birds five arthropod groups each 16‐km 2 landscape, recorded various...
In this study we introduce a new indicator for private consumption based on search query time series provided by Google Trends. The is factors extracted from consumption-related categories of the Trends application Insights Search. forecasting performance assessed relative to two most common survey-based indicators: University Michigan Consumer Sentiment Index and Conference Board Confidence Index. results show that in almost all conducted in-sample out-of-sample experiments outperforms...
Atrazine, propazine, and terbuthylazine are chlorotriazine herbicides that have been frequently used in agriculture thus potential drinking water contaminants. Hydroxyl radicals produced by advanced oxidation processes can degrade these persistent compounds. These also very reactive with sulfate (2.2–3.5 × 109 M–1 s–1). However, the dealkylated products of pesticides less toward (e.g., desethyl-desisopropyl-atrazine (DEDIA; 1.5 108 s–1)). The high reactivity is largely due to ethyl or...
Background: Osteoporosis is a widespread disease of the skeleton that becomes more common with advancing age.Its prevalence still inadequately documented.The goal this study to determine how osteoporosis in Germany.Methods: The routine billing data large statutory health insurance carrier Germany (the TK company) from years 2006 2009 were anonymized and retrospectively analyzed.Insurees aged 50 above identified either their bearing diagnosis or osteoporosis-related fractures, having received...
Permanently charged and ionizable organic compounds (IOC) are a large diverse group of belonging to many contaminant classes, including pharmaceuticals, pesticides, industrial chemicals, natural toxins. Sorption mobility IOCs distinctively different from those neutral compounds. Due electrostatic interactions with sorbents, existing concepts for describing sorption, by extension mobility, inadequate IOC. Predictive models developed based on octanol–water partitioning (Kow) organic-carbon...
Abstract Diethylenetriamine penta(methylenephosphonate) (DTPMP) and related aminopolyphosphonates (APPs) are widely used as chelating agents in household industrial applications. Recent studies have linked APP emissions to elevated levels of the herbicide glyphosate European surface waters. However, transformation processes products APPs environment largely unknown. We show that is formed from DTPMP by reaction with manganese at near neutral pH pure water wastewater. Dissolved Mn 2+ O 2 or...
Ozonation of diclofenac in aqueous solution the presence and absence an •OH scavenger, tertiary butanol (t-BuOH), was studied, most important reaction intermediates products were identified. The second-order O3 rate constant determined by competition with buten-3-ol found to be 6.8 × 105 M−1 s−1 at 20 °C. From this high constant, it has been concluded that must initially add on amino nitrogen. Decomposition adduct results formation •− (→ •OH) aminyl radical precursors. A free yield 30%...
Compound-specific analysis of stable carbon and hydrogen isotopes was used to assess the fate gasoline additive methyl tert-butyl ether (MTBE) its major degradation product alcohol (TBA) in a groundwater plume at an industrial disposal site. We present novel approach evaluate two-dimensional compound-specific isotope data with potential identify reaction mechanisms quantify extent biodegradation complex field sites. Due widespread contaminant plume, multiple MTBE sources, presence numerous...
The peroxone process is one of the AOPs that lead to (•)OH. Hitherto, it has been generally assumed (•)OH yield unity with respect O3 consumption. Here, experimental data are presented suggest must be near 0.5. first evidence derived from competition experiments. consumption 4-chlorobenzoic acid (4-CBA), 4-nitrobenzoic (4-NBA) and atrazine present in trace amounts (1 μM) followed as a function concentration solution containing H2O2 mM) tertiary butanol (tBuOH, 0.5 excess over compounds.

ABSTRACT Aim Species richness in itself is not always sufficient to evaluate land management strategies for nature conservation. The exchange of species between local communities may be affected by landscape structure and land‐use intensity. Thus, turnover, its inverse, community similarity, useful measures integrity from a diversity perspective. Location A European transect France Estonia. Methods We measured the similarity plant, bird, wild bee, true bug, carabid beetle, hoverfly spider...
