Urine selenium concentration is a useful biomarker for assessing population level selenium status (2019)
Journal Article

Plasma selenium (Se) concentration is an established population level biomarker of Se status, especially in Se-deficient populations. Previously observed correlations between dietary Se intake and urinary Se excretion suggest that urine Se concentrat...

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.

Investigating the use of microdialysis and SEC-UV-ICP-MS to assess iodine interactions in soil solution (2019)
Journal Article

Element cycling in the terrestrial environment is heavily reliant upon processes that occur in soil solution. Here we present the first application of microdialysis to sample iodine from soil solution. In comparison to conventional soil solution extr...

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.

The risk of selenium deficiency in Malawi is large and varies over multiple spatial scales (2019)
Journal Article

Selenium (Se) is an essential human micronutrient. Deficiency of Se decreases the activity of selenoproteins and can compromise immune and thyroid function and cognitive development, and increase risks from non-communicable diseases. The prevalence o... Read More about The risk of selenium deficiency in Malawi is large and varies over multiple spatial scales.

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...
