© 2019 The Author(s). Background: Micronutrient deficiencies including selenium (Se) are widespread in Malawi and potentially underlie a substantial disease burden, particularly among poorer and marginalised populations. Concentrations of Se in stapl... Read More about Can selenium deficiency in Malawi be alleviated through consumption of agro-biofortified maize flour?

Using chemical fractionation and speciation to describe uptake of technetium, iodine and selenium by Agrostis capillaris and Lolium perenne. Journal of Environmental Radioactivity, 212, Article 106131. https://doi.org/10.1016/j.jenvrad.2019.106131

© 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...

Kinetics of 99Tc speciation in aerobic soils (2019)
Journal Article
Izquierdo, M., Bailey, E. H., Crout, N. M., Sanders, H. K., Young, S. D., & Shaw, G. G. (2020). Kinetics of 99Tc speciation in aerobic soils. Journal of Hazardous Materials, 388, Article 121762. https://doi.org/10.1016/j.jhazmat.2019.121762

© 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.

Urine selenium concentration is a useful biomarker for assessing population level selenium status (2019)
Journal Article
Phiri, F. P., Ander, E. L., Lark, R. M., Bailey, E. H., Chilima, B., Gondwe, J., …Broadley, M. R. (2020). Urine selenium concentration is a useful biomarker for assessing population level selenium status. Environment International, 134, Article 105218. https://doi.org/10.1016/j.envint.2019.105218

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...

Chemical and isotopic fractionation of lead in the surface soils of Egypt (2019)
Journal Article
Shetaya, W. H., Marzouk, E. R., Mohamed, E. F., Bailey, E. H., & Young, S. D. (2019). Chemical and isotopic fractionation of lead in the surface soils of Egypt. Applied Geochemistry, 106, 7-16. https://doi.org/10.1016/j.apgeochem.2019.04.013

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
Phiri, F. P., Ander, E. L., Bailey, E. H., Chilima, B., Chilimba, A. D. C., Gondwe, J., …Broadley, M. R. (2019). The risk of selenium deficiency in Malawi is large and varies over multiple spatial scales. Scientific Reports, 9(1), Article 6566. https://doi.org/10.1038/s41598-019-43013-z

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.
