Presence of emerging contaminants in treated sludges and their potential impacts on the environment
(NUI Galway, 2018-11-13)
Landspreading of sewage sludge remains the most economical and practical means for its disposal, with some countries, such as Ireland, disposing up to 90% to land. Its nitrogen, phosphorus and metal content make it an ...
Changes in the fractionation profile of Al, Ni and Mo during bioleaching of spent hydroprocessing catalysts with Acidithiobacillus ferrooxidans.
(Taylor & Francis, 2018-06-05)
Spent hydroprocessing catalysts are known to contain a variety of potentially toxic metals and therefore studies on the bioavailability and mobility of these metals are critical for understanding the possible environmental ...
Enhancement of bauxite residue as a low-cost absorbent for phosphorus in aqueous solution, using seawater and gypsum treatments.
(Elsevier, 2018-01-20)
Bauxite residue (red mud), the by-product produced in the alumina industry, is being produced at an estimated global rate of approximately 150Mt per annum. Due to its highly alkaline nature, many refineries use neutralisation ...
Contrasting yield responses to phosphorus applications on mineral and organic soils from extensively managed grasslands: Implications for P management in high ecological status catchments
(Wiley, 2018-09-13)
Phosphorus (P) loss from grassland production is one of the main causes affecting high status water bodies in Europe. Soils with a high content in organic matter (OM), even if extensively managed, are particularly vulnerable ...
Effects of fertiliser on phosphorus pools in soils with contrasting organic matter content: A fractionation and path analysis study
(Elsevier, 2018-12-05)
With the intensification of agricultural production in many European countries, more marginal soils with elevated organic matter (OM) content are being brought into cultivation. However, little is known about the transformations ...
An evaluation of the general composition and critical raw material content of bauxite residue in a storage area over a twelve-year period
(Elsevier, 2018-10-09)
Bauxite residue, the by-product produced in the alumina industry, is being produced at an estimated global rate of approximately 150 million tonnes per annum. Currently, the reuse of bauxite residue is low (∼2%), due to ...
