© 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?

© 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...

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.
