Significance and Use

This practice is intended for the digestion of lead in dust wipe samples collected during various lead hazard activities performed in and around buildings and related structures.

This practice is also intended for the digestion of lead in dust wipe samples collected during and after building renovations.

This practice is applicable to the digestion of dust wipe samples that have or have not been collected in accordance with Practice E1728 using wipes that may or may not conform to Specification E1792 .

This practice is applicable to the digestion of dust wipe samples that were placed in either hard-walled, rigid containers such as 50-mL centrifuge tubes or flexible plastic bags.

Note 2Due to the difficulty in performing quantitative transfers of some samples from plastic bags, hard-walled rigid containers such as 50-mL plastic centrifuge tubes are recommended for sample collection.

Digestates prepared according to this practice are intended to be analyzed for lead concentration using spectrometric techniques such as Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) and Flame Atomic Absorption Spectrometry (FAAS) (see Test Method E1613 ), or using electrochemical techniques such as anodic stripping voltammetry (see Practice E2051 ).

This practice is not capable of determining lead bound within matrices, such as silica, that are not soluble in nitric acid.

This practice is capable of determining lead bound within paint.

1. Scope

1.1 This practice covers the acid digestion of surface dust samples (collected using wipe sampling practices) and associated quality control (QC) samples for the determination of lead.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This practice contains notes which are explanatory and not part of mandatory requirements of the standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
