Metallic Profile of Whole Blood and Plasma in a Series of 99 Healthy Children.

In recent years, special emphasis has been put on heavy metals. Children are very sensitive to accumulation of metals. Furthermore, as regards elements, the reference values in children are scarce in the literature as it is difficult to obtain the large quantity of blood necessary to analyze many metals by the conventional atomic absorption spectrometry technique.

Metallic profile of whole blood and plasma in a series of 106 healthy volunteers.

In 2003, we simultaneously quantified 27 metals by inductively coupled plasma-mass spectrometry (ICP-MS) in the whole blood, plasma and urine of 100 healthy volunteers. We again determined the metallic profile in whole blood and plasma during 2012. ICP-MS validated multielementary method was performed for metals in whole blood and plasma.

Importance of anthropogenic metals in hospital and urban wastewater: its significance for the environment.

Thirty-four metals were analyzed by ICP-MS. Among these elements, anthropogenic silver, gadolinium and platinum, were representative markers of medical activities in hospital and urban wastewater. On working days, median hospital wastewater concentrations for anthropogenic silver, gadolinium, and platinum were approximately three, 13 and 27 times higher respectively than the Municipal wastewater.

[The metallic profile: a new biological concept].

Considerable advances have been made in metals and metalloids analysis over the past decade. This analysis is a basic stage in deficiency or toxicity assessment. A recently introduced technique, inductively coupled plasma mass spectrometry (ICP-MS) is progressively replacing atomic absorption.

[Inductively coupled plasma: a promising new tool with application in human toxicology and public health].

The authors describe the use of inductively coupled plasma to detect 32 metals and metalloids in blood, urine, hair and nails. They also report the first case of gadolinium overdose documented by blood analysis with this method Metal speciation, a new approach developed in our laboratory, can distinguish between toxic and non toxic metals.

Metal and metalloid multi-elementary ICP-MS validation in whole blood, plasma, urine and hair. Reference values.

Four multi-elementary metal and metalloid quantification methods using inductively coupled plasma mass spectrometry (ICP-MS) were developed and validated in human whole blood, plasma, urine and hair by means of a single preparation procedure for each sample. The ICP-MS measurements were performed using a Thermo Elemental X7CCT series and PlasmaLab software without a dynamic reaction cell. With this procedure 27-32 elements can be simultaneously quantified in biological matrices: Li, Be, B, Al, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Rb, Sr, Mo, Pd, Ag, Cd, Sn, Sb, Te, Ba, W, Pt, Hg, Tl, Pb, Bi, U.
