Biomonitoring California Protocol for Following up on Elevated Levels of Urinary Arsenic.

ABSTRACT:

Objectives

to develop and implement a follow-up protocol for Biomonitoring California study participants with elevated levels of urinary arsenic, particularly inorganic forms.

Methods

We selected 20 μg/L as the level of concern for urinary inorganic arsenic; samples with total arsenic ≥20 μg/L were speciated. Participants with elevated inorganic arsenic were notified of their level and invited to participate in a telephone survey to help determine possible exposure sources. We illustrate the protocol in four Biomonitoring California studies, which collected samples from 2010-2013 in locations across the state.

Results

48 participants in the four studies had elevated urinary inorganic arsenic levels. Consumption of rice and rice-based products was the mos
