Summary
This study developed the first bovine blood lead standard reference material, crucial for accurate lead testing in cattle. The material meets national standards, ensuring reliable analytical results for bovine lead levels.
Area of Science:
- Analytical Chemistry
- Veterinary Science
- Environmental Health
Context:
- Accurate quantification of lead in bovine blood is essential for public health and animal welfare.
- Existing reference materials for bovine blood lead are limited, necessitating the development of national standards.
- Lead exposure in cattle can have significant economic and health implications.
Purpose:
- To establish the first grade standard analytical reference material for bovine blood lead.
- To ensure the accuracy and reliability of lead measurements in bovine blood samples.
- To meet national standard material requirements for bovine blood lead analysis.
Summary:
- A bovine blood lead reference material was developed using acetate lead administration and validated against USA NIST SRM 955b.
- The material demonstrated excellent homogeneity and stability over 14 months, with characteristic lead values at low, medium, and high concentrations.
- The developed reference material successfully met national standards for analytical reference materials.
Impact:
- Provides a reliable standard for accurate lead testing in bovine blood, supporting regulatory compliance and disease surveillance.
- Enhances the quality control of laboratory diagnostics for lead poisoning in cattle.
- Contributes to improved food safety and environmental monitoring programs.
