Biologically Essential and Non-Essential Elements Causing Toxicity in Environment

Journal of Environmental & Analytical Toxicology, 2018
This paper encompasses the toxicity of abundant and trace elements present on the earth. Generally, the less abundant elements are more toxic. But even the biologically essential elements become toxic above a critical concentration. The synergistic influence of a metal on toxicity of another is also discussed for mercury selenium and zinc-cadmium pairs.

Essential and Non-essential Elements in Scalp Hair of Diabetics: Correlations with Glycated Hemoglobin (HbA1c)

Biological and Pharmaceutical Bulletin, 2018
Essential elements (Ca, Mg, Zn, Cu, Fe, Cr, Mn and V) and non-essential elements (As, Cd, Hg and Pb) were measured in scalp hair samples of 45 diabetic subjects and 59 control subjects in Japan using inductively coupled plasma mass spectrometry. All diabetic subjects took insulin and/or antidiabetic agents, with glycated hemoglobin (HbA1c) ranging ...

A genome-wide association study provides insights into the genetic etiology of 57 essential and non-essential trace elements in humans

Communications Biology
Trace elements are important for human health but may exert toxic or adverse effects. Mechanisms of uptake, distribution, metabolism, and excretion are partly under genetic control but have not yet been extensively mapped.
