Bioaccumulation of metals in ryegrass (Lolium perenne L.) following the application of lime stabilised, thermally dried and anaerobically digested sewage sludge.
(Elsevier ScienceDirect, 2016-05-09)
The uptake and accumulation of metals in plants is a potential pathway for the transfer of environmental contaminants in the food chain, and poses potential health and environmental risks. In light of increased population ...
Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: a critical review
(Elsevier, 2017-01-06)
Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its ...
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 ...
Stabilisation of a dredged marine sediment: geotechnical and contaminant leaching properties
(Civil Engineering Research in Ireland CERI, 2018-08-29)
In this paper, contaminated sediment dredged from a commercial harbour in Ireland was stabilized using Ordinary Portland cement (OPC) alone and in combination with Ground Granulated Blast Furnace Slag (GGBS). The engineering ...
Metal concentrations in lime stabilised, thermally dried and anaerobically digested sewage sludges.
(Elsevier ScienceDirect, 2015-11-25)
Cognisant of the negative debate and public sentiment about the land application of treated sewage sludges ( biosolids ), it is important to characterise such wastes beyond current regulated parameters. Concerns may be ...
Nutrient, metal and microbial loss in surface runoff following treated sludge and dairy cattle slurry application to an Irish grassland soil
(Elsevier, 2015)
Treated municipal sewage sludge ( biosolids ) and dairy cattle slurry (DCS) may be applied to agricultural land as an organic fertiliser. This study investigates losses of nutrients in runoff water (nitrogen (N) and ...
