[Detection of lead in environmental objects and biologic materials during monitoring]. / Opredelenie svintsa v ob"ektakh okruzhaiushchei sredy i biologicheskikh substratakh pri provedenii monitoringa.

The authors specified methods to detect lead in biologic materials. The quality control covered use of Russian and foreign standard samples, the results proved to agree. Lead was detected by AAS technique (direct and flow-type variants with preliminary concentration of lead) and ELRA method. The authors determined measurement limits sufficient for analysis of complex biologic materials. The measurement range for lead varied from 0.002 mg/kg (plants) to 3,000 mg/kg (soil); the range of serum lead levels was < 0.5-39 mg/dl.
