Insights

This study establishes pediatric reference values for heavy metals in children using a novel ICP-MS method. The findings provide crucial data for assessing metal exposure and toxicity in pediatric populations.

Area of Science:

  • Environmental Science
  • Toxicology
  • Pediatrics

Background:

  • Heavy metal exposure poses significant risks, particularly to children's health.
  • Establishing pediatric reference values for metals is challenging due to limited blood sample requirements for conventional methods.
  • Existing elemental reference values for children are scarce in scientific literature.

Purpose of the Study:

  • To adapt and validate an inductively coupled plasma mass spectrometry (ICP-MS) method for multielemental analysis in pediatric blood and plasma.
  • To determine pediatric reference values for 25 elements in whole blood and 23 elements in plasma.
  • To compare elemental concentrations across different age groups in children and between children and adults.

Main Methods:

  • Utilized a validated inductively coupled plasma mass spectrometry (ICP-MS) technique requiring only 0.3 mL of whole blood or plasma.
  • Analyzed samples from 99 healthy children aged under 5 to under 18 years.
  • Quantified 25 elements in whole blood and 23 elements in plasma simultaneously.

Main Results:

  • Successfully established a pediatric elemental profile for whole blood and plasma.
  • Observed variations in metallic concentrations among different pediatric age groups.
  • Identified differences in metallic concentrations between pediatric and adult populations.

Conclusions:

  • The developed pediatric metallic profile is a valuable tool for clinical and forensic toxicology.
  • This method facilitates accurate assessment of environmental metal exposure in children.
  • The study provides essential data for understanding metal accumulation and toxicity in pediatric health.

Composition of Blood

The blood in our bodies comprises three major components: blood plasma, formed elements, and the extracellular matrix. Blood plasma is a yellowish fluid that constitutes 55% of the total blood volume. It is primarily made up of water and essential substances such as electrolytes and proteins. Blood plasma serves as a medium for transporting blood cells and also contains nutrients, enzymes, hormones, antibodies, and gases.
Formed elements constitute the remaining 45% of the blood volume. These...

Composition of Blood Plasma01:24

Composition of Blood Plasma

Blood plasma is a fluid that contains approximately 92% water and 8% solutes. The solutes include various types of proteins, which constitute about 7% of the total solutes in the plasma. The high-molecular-weight proteins—albumins, globulins, and fibrinogen—are essential to plasma function. Albumins, making up about 60% of the plasma proteins, maintain the osmotic balance within blood vessels by preventing excessive water leakage. Additionally, albumins serve as carrier proteins,...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Characteristics and Functions of Blood

Blood is specialized connective tissue comprising about 8% of the body mass. It has a thick, liquid extracellular matrix that contains cells, dissolved proteins, and electrolytes, making it five times more viscous than water. Blood is warm, around 38°C, and has an alkaline pH ranging from 7.35 to 7.45.
The primary function of blood is to transport oxygen and carbon dioxide between tissues and the lungs. Oxygenated blood is bright red, while oxygen-depleted blood is darker. It also carries...
