trace element

any of various chemical elements, such as iron, manganese, zinc, copper, and iodine, that occur in very small amounts in organisms and are essential for many physiological and biochemical processes

trace element

[′trās ‚el·ə·mənt]
(analytical chemistry)
An element in a sample that has an average concentration of less than 100 parts per million atoms or less than 100 micrograms per gram.
(biochemistry)
A chemical element that is needed in minute quantities for the proper growth, development, and physiology of the organism. Also known as micronutrient.
(geochemistry)
An element found in small quantities (usually less than 1.0%) in a mineral. Also known as accessory element; guest element.

Living organisms are exposed to trace elements from different sources, for example, diet, environment (water, soil, and air), or biomaterials.
In those cases when the concentration of a certain trace element was below the detection level and could not be detected directly in the TCA filtrate, we used the concentration/extraction method: added 0,5 ml of 2% sodium diethyldithiocarbamate solution and 2 drops of TRITON-X-100 detergent to 2,5 ml of serum and vigorously shook the mixture for 10 seconds.

As it is evident from Tables 3 and 4 there was no correlation found between trace element content of hair and serum when compared two by two; the P values are not significant (>0.05) and Pearson correlation coefficient is very small, almost near zero.
