Abstract The paper deals with an analysis of the amount 16 polycyclic aromatic hydrocarbons (PAHs (Polycyclic hydrocarbons—16 defined by US EPA.)) released from reclaimed asphalt mixtures used in base layers road surfaces and binder construction using cold in-place recycling. For ten samples tested, sum PAHs was determined directly for crushed mixture its 24-h leachate. were to make cylindrical specimens recycling mixture. prepared simulate as realistically possible use reconstructions...
Although growth stimulation at low arsenic doses was observed in several plants, few studies have focused on this phenomenon more detail. The effects of different concentrations (0-50 mg kg-1 soil: As0-As50) the and selected physiological parameters two maize cultivars (Zea mays L. cvs. Chapalu MvNK 333) were tested. Cultivar 333 manifested a generally higher tolerance to As than cv. Chapalu, which may be related lower content tissues. highest stimulatory effect recorded As1 As2 (cv....
The article provides information about a new device, AlgaTox developed in the R&D project sponsored by Technology Agency (n.TA02030179) and patented Czech Republic (CZ 305687). Its functionality is based on use of biosensor, its main advantage fast response rate. toxicity detection achieved through precise measurement green algae oxygen production dynamics after their exposure to light wavelength 680 nm. Clark sensor with resolution 0.05% equilibrium concentrations stability at constant...
Abstract Toxicity assessment of K 2 Cr O 7 , ZnCl and NiCl .6H focusing on the green unicellular alga Desmodesmus subspicatus showed that Ni was most toxic (EC 50 = 0.121 mg L −1 ), followed by 0.357 ) Zn 0.968 ). The exposed to solutions individual metals their mixtures (Zn + Ni, Cr). After 48, 72 96 h exposure, accumulation Zn, in algal cells assessed. Moreover, change toxicity metals, concentration selected biogenic elements (Ca, Na, Mg, S, K, P, Mn) rate metal removal from were also...
Construction of motorways and road traffic bring a new line element into the landscape, which fundamentally influences local hydrological regime water quality. Impermeable surfaces are introduced affecting natural infiltration in environment. The aim present research was to assess long-term historical development changes landscape retention potential due construction D1 motorway Jihlava region also evaluate impact winter maintenance on quality surface waters soils. During reference period,...
Abstract The article deals with the contamination of soil in vicinity D1 motorway caused by application chemical de-icing agents winter. In selected area, during a period one year (from October 2017 to 2018), samples were regularly collected once month at five different distances from road. Chloride concentrations aqueous extracts monitored and degree toxicity was established for living organisms. resulting chloride load evaluated respect precipitation activity amount salt applied area....
Abstract Monitoring of pollution in the vicinity roads connected to winter road maintenance is one important tools for optimising technology and reducing its environmental impact. The aim this study was determine relationship between increased concentration sodium ion characterize harm caused by de-icing agents on selected types individual components grown Norway Spruce ecosystem. model area located immediate D1 motorway connecting Prague Brno (Czech Republic), at 103rd kilometer. thus...
