EPA Method 7470A (SW-846): Mercury in Liquid Wastes (Manual Cold-Vapor Technique)

Applicability: EPA Method 7470A, specifically known as “Mercury in Liquid Waste (Manual Cold-Vapor Technique)”, is applicable for determining the concentration of mercury in liquid samples, including mobility procedure extracts, aqueous wastes, and groundwaters. It can also be used for analyzing certain solid and sludge-type wastes, though Method 7471B is generally preferred for those.

Purpose: The primary purpose is to quantify mercury levels in liquid samples, typically those generated from environmental or waste management contexts.
