Using chemical fractionation and speciation to describe uptake of technetium, iodine and selenium by Agrostis capillaris and Lolium perenne (2019)
Journal Article

© 2019 Elsevier Ltd To understand the dynamic mechanisms governing soil-to-plant transfer of selenium (Se), technetium-99 (99Tc) and iodine (I), a pot experiment was undertaken using 30 contrasting soils after spiking with 77Se, 99Tc and 129I, and in...

Agronomic biofortification of leafy vegetables grown in an Oxisol, Alfisol and Vertisol with isotopically labelled selenium (77Se) (2019)
Journal Article

© 2019 Elsevier B.V. Selenium biofortification of crops is a proven technology for improving dietary nutrition. This study used isotopically labelled selenate (>99% enriched 77Se) to assess uptake and Se availability to two green vegetables, Brassica...

Kinetics of 99Tc speciation in aerobic soils (2019)
Journal Article

© 2019 The Authors Technetium-99 is a significant and long-lived component of spent nuclear fuel relevant to long-term assessments of radioactive waste disposal. Whilst 99Tc behaviour in poorly aerated environments is well known, the long-term bioava... Read More about Kinetics of 99Tc speciation in aerobic soils.

Uptake competition between selenium and sulphur fertilizers in sequential harvests of ryegrass: A stable isotope study (2019)
Conference Proceeding

The demand for sulphur (S) fertilizers has increased due to declining S emissions from coal burning and subsequent deposition on agricultural land. Slow-release S may only be beneficial for grass Selenium (Se) status initially and less beneficial for...

Effect of soil properties and contact time on selenium transfer to wheat (2019)
Conference Proceeding

Selenium biofortification of a wheat crop in northeastern Pakistan using 77Se as a tracer (2019)
Conference Proceeding

Selenium (Se) is an important dietary micronutrient for human and animal health and it is a vital component of various selenoproteins that play an essential role in regulating multiple body functions, including metabolism, thyroid hormone synthesis,...

Uptake of trace elements by food crops grown within the Kilembe copper mine catchment, Western Uganda (2019)
Journal Article

The mining and processing of copper from the Kilembe mine between 1956 and 1982 left behind millions of tons of cupriferous and cobalt ferrous mine tailings within the Kilembe mine catchment. Subsequent erosion and deposition of the tailings into adj... Read More about Uptake of trace elements by food crops grown within the Kilembe copper mine catchment, Western Uganda.

Chemical and isotopic fractionation of lead in the surface soils of Egypt (2019)
Journal Article

Chemical fractionation via sequential extraction (SEP) combined with isotopic analysis of Pb was used to investigate the origins and reactivity of Pb in 66 topsoil samples collected from 12 different locations in Egypt. The total soil Pb concentratio... Read More about Chemical and isotopic fractionation of lead in the surface soils of Egypt.

Iodine bioavailability in acidic soils of Northern Ireland (2019)
Journal Article

Iodine is an essential trace element for humans and grazing animals and is often deficient. Our aim was to investigate the role of soil properties in retaining and ‘fixing' iodine in soils and thereby controlling its phyto-availability to grass. Soil...

Lead in Egyptian soils: Origin, reactivity and bioavailability measured by stable isotope dilution (2017)
Journal Article

© 2017 Elsevier B.V. The current availability of Pb in Egyptian soils and associated plants were studied in 15 locations (n = 159) that had been historically subjected to industrial and automobile Pb emissions. Isotopic dilution with enriched 204Pb w... Read More about Lead in Egyptian soils: Origin, reactivity and bioavailability measured by stable isotope dilution.
