1 ADULT LEAD EXPOSURE Richard Rabin Lead Registry Coordinator Massachusetts Division of Occupational Safety

2 Health Effects Cancer Cataracts High blood pressure Decreased life span Decreased cognition Peripheral arterial disease (PAD)

3 Sources - Occupational Construction Bridge painting House and commercial painting Deleading Demolition

4 Sources - Occupational Manufacturing Foundries Smelters Batteries Glass Plastics

5 Sources - Occupational Services/repair Autobody, paint refinishing Auto radiator repair Recycling – batteries, scrap metal, computers

6 OSHA Lead Standards General Industry (1978) Construction (1993)

7 OSHA Lead Standards Maximum allowable air lead level –.05 mg/m³ (50 mcg/m³) Protective measures Ventilation Respirators Personal protective clothing Separate eating area Showers, changing area Medical monitoring Medical exams Blood lead testing Medical removal, paid if blood lead => 50 mcg/dl

8 Sources - Non- occupational Firing ranges; “reloading” (at home) Home renovation and painting Remedies Litargirio Greta Ayurvedic medicines Herbs prepared in lead-soldered pots

9 Take-home Exposure Sources lead dust on body, clothes, shoes taken home contamination of home, car

10 Take-home Exposure Meta-analysis of 10 reports (NIOSH, 1999) Children of lead-exposed workers vs. US population Mean BLL: ~ 2.5 times higher Percent => 10 mcg/dl: 52% vs. 8.9% Percent => 20 mcg/dl: 21% vs. 1.1%

11 Take-home Exposure Construction workers study (NIOSH and NJ Health Dept., 1997) * most workers brought work clothes home; * employers with no shower facilities * dust lead levels higher in workers’ homes and cars than in controls’ * workers’ children’s BLL (26% => 10 mcg/dl) vs. controls’ BLL (5%)

12 Adult Lead Registries NIOSH Funding (~35 states) Coordination, data analysis Health People 2010 goal: elimination of BLLs => 25 mcg/dl

13 Adult Lead Registries Purposes Identify industries with over-exposures Identify individual companies Education for workers, management, physicians Publicize findings

14 Adult Lead Registries Basic elements Labs required to report (similar to childhood programs) Blood lead level (MA: => 15 mcg/dl) Patient information Physician information

15 Adult Lead Registries Follow-up Contact health care provider (HCP) Information on patient Educate HCP Contact patient/worker Interview Educate Workplace Industrial hygiene investigation Referral to OSHA- funded consultation Referral to OSHA Special projects – training, educational material

16 Adult Lead Registries Data analysis and dissemination Limitations Many workers/adults not tested Most registries do not receive reports of all tests (low levels)

17 House Painting High lead exposures Power sanding (up to a few mg/m³) Scraping Heat gun

18 House Painting Poor control of dust Sanding – no vacuum attachment Scraping – no misting Tracking dust from one area to another Dry sweeping Non-HEPA v acuuming

19 Data from 1996 – 2001 report (BLL => 40 mcg/dl) House and commercial painting (excl. bridge) – 94 (33% of occupational cases) Deleading - approx. 65 (23%) Workers with young children (< 6 years old) – approx. 25% Hispanic ethn. – 9.5% (4.7% in working pop.)

20 Data from 1996 – 2001 report (BLL => 40 mcg/dl) Compliance with OSHA lead standard Medical monitoring program House painters - 21% Deleaders – approx. 90% Training on lead hazards House painters – 29% Deleaders – approx. 90%

21 Data from 1996 – 2001 report (BLL => 40 mcg/dl) Non-occupational cases Home renovation & painting – 3% Target shooting – 3%
