A new approach to a legacy concern: Evaluating machine-learned Bayesian networks to predict childhood lead exposure risk from community water systems.

Publication Type:Academic Journal

Source(s):Environmental research [Environ Res] 2022 Mar; Vol. 204 (Pt B), pp. 112146. Date of Electronic Publication: 2021 Sep 29.

Abstract:Lead in drinking water continues to put children at risk of irreversible neurological impairment. Understanding drinking water system characteristics that influence blood lead levels is needed to prevent ongoing exposures. This study sought to assess t...

Childhood blood lead levels and environmental risk factors in Madagascar.

Publication Type:Academic Journal

Source(s):Environmental science and pollution research international [Environ Sci Pollut Res Int] 2022 Sep; Vol. 29 (45), pp. 68652-68665. Date of Electronic Publication: 2022 May 11.

Abstract:One-third of children globally have blood lead levels (BLLs) exceeding the (former) US CDC reference value of 5 µg/dL; this value may be as high as one-half for children in low- and middle-income countries (LMICs). Lead exposure occurs through a variet...

Elevated water lead levels in schools using water from on-site wells.

Publication Type:Academic Journal

Source(s):Journal of water and health [J Water Health] 2022 Sep; Vol. 20 (9), pp. 1425-1435.

Abstract:Only 8% of US public schools operate their own community water systems, and thus are subject to the federal Lead and Copper Rule's regulation of water lead levels (WLLs). To date, the absence of parallel water testing data for all other schools has pre...
