Advances on Understanding and Detecting the Prevalence of Lead Hazards in Housing
September 1, 2020
2:00–3:00 PM Eastern Daylight Time



This webinar covers a new lead-based paint testing method, and new information on residential LBP and LBP hazards prevalences. For renovation, repair and painting on older U.S. housing, LBP presence requires lead safe work practices and post-work testing. To enhance chemical spot test kit performance for determining LBP, two improved (rhodizonate, sulfide) kits were developed and validated. The rhodizonate kit couldn’t dissolve all the lead, but a sulfide kit enhanced by solid state dilution and other refinements had specificity and sensitivity comparable to portable X‑ray fluorescence analyzers. The sulfide kit didn’t meet EPA’s RRP rule test kit criterion, which thus appears too stringent for any test kit or XRF. Lead safety program targeting is enhanced when reflecting LBP and LBP hazard variations by geography, sociodemographics, and housing characteristics. With household surveys becoming less accurate (less public cooperation), for HUD’s American Healthy Homes Survey II (2019), it updated its resident contact, screening, recruitment, inspection and sampling methods; these, and LBP and LBPH prevalence decreases since AHHS I (2006) will be described.

Learning Objectives

After participating in this webinar, attendees will:

  • Learn how to use chemical spot test kits before renovation, repair, and painting projects in older homes, and the rationale for their use.
  • Learn the effectiveness of currently available commercial spot test kits in determining lead-based paint, and areas for improvement re EPA criteria.
  • Learn the effectiveness of the HUD research's spot test kits, and how that relates to EPA regulatory criteria.
  • Learn the major findings on the trends in the prevalences of lead-based paint and lead-based paint hazards in US housing from 2006 to 2019.
  • Learn methods for improving household survey participation in the current climate regarding surveys.

What is an ACGIH® Webinar?

ACGIH® is dedicated to providing quality, scientific, educational events. One method of doing this is to offer distance-learning webinars. A webinar, short for Web-based seminar, is a presentation, lecture, or seminar that is transmitted over the Internet. A key feature of a webinar is its interactive elements — the ability to give, receive and discuss information. Webinars are as effective as on-site presentations without the travel expense. This ACGIH® webinar is 1.0 hours in duration and consists of a live presentation given via the Internet with no option for call in audio.
