Bioavailability and risk assessment of potentially toxic elements in garden edible vegetables and soils around a highly contaminated former mining area in Germany
(2017)Although soil contamination by potentially toxic elements (PTEs) in Europe has a history of many centuries, related problems are often considered as having been dealt with due to the enforcement of tight legislations. ... -
Biosolids application affects the competitive sorption and lability of cadmium, copper, nickel, lead, and zinc in fluvial and calcareous soils
(2017)The objective of this research was to investigate the effects of biosolids on the competitive sorption and lability of the sorbed Cd, Cu, Ni, Pb, and Zn in fluvial and calcareous soils. Competitive sorption isotherms were ... -
Biotreatment and bacterial succession in an upflow immobilized cell bioreactor fed with fludioxonil wastewater
(2021)The large quantities and the persistent nature of fungicide wastewaters have increased the efforts towards a sustainable technological solution. In this context, fludioxonil-contaminated wastewater was treated in an upflow ... -
Challenges in microbially and chelate-assisted phytoextraction of cadmium and lead – A review
(2021)Cadmium (Cd) and lead (Pb) are ubiquitously present in surface soils, due to anthropogenic activities, causing threat to ecological and human health because of their carcinogenic nature. They accumulate in large quantities ... -
Characterization of the biodegradation, bioremediation and detoxification capacity of a bacterial consortium able to degrade the fungicide thiabendazole
(2017)Thiabendazole (TBZ) is a persistent fungicide used in the post-harvest treatment of fruits. Its application results in the production of contaminated effluents which should be treated before their environmental discharge. ... -
Chemical characterisation, antibacterial activity, and (nano)silver transformation of commercial personal care products exposed to household greywater
(2019)The objective of this study was to test the original speciation of silver (Ag) in eight different commercially available personal care products and investigate the chemical transformation of Ag during exposure to two types ... -
Combined toxicity of cannabidiol oil with three bio-pesticides against adults of sitophilus zeamais, rhyzopertha dominica, prostephanus truncatus and trogoderma granarium
(2020)The present study investigates the interaction between cannabidiol (CBD) oil and three biopesticides: Azatin and two baculovirus formulations (Madex and Helicovex), both separately and in combination, in order to investigate ... -
A critical prospective analysis of the potential toxicity of trace element regulation limits in soils worldwide: Are they protective concerning health risk assessment? - A review
(2019)Trace elements (TEs) may have toxic effects to plants and humans; thus, countries and organizations impose maximum allowable regulation limits of their concentrations in soils. Usually such limits are placed in different ... -
Detection of future changes in seasonality in extreme short-term rainfall in selected stations of Slovakia
(2017)This paper analyses the projected changes in short-term rainfall events during the warm season (April-October) in an ensemble of 30 regional climate model (RCM) simulations. The seasonality analysis was done for the ... -
Fish welfare in aquaponic systems: Its relation to water quality with an emphasis on feed and faeces-A review
(2017)Aquaponics is the combination of aquaculture (fish) and hydroponic cultivation of plants. This review examines fish welfare in relation to rearing water quality, fish feed and fish waste and faeces to develop a sustainable ... -
Hazardous toxic metal(loid)s in top- and deep-soils during the transformation of aquaculture ponds restored to farmland
(2022)The pollution risks due to the soil migration of toxic metal(loid)s (TMs) are a greatly hazard to ecological environment as well as animal and human health. Previous studies have primarily focused on surface contamination ... -
Hexavalent chromium availability and phytoremediation potential of Cichorium spinosum as affect by manure, zeolite and soil ageing
(2017)Cichorium spinosum (spiny chicory) is a wild edible vegetable, and a possible suitable species for Cr(VI)-phytoremediation. There are three approaches for altering Cr(VI) dynamics: reduction to Cr(III) by organic matter ... -
