Summary
In 1986, lead exposure in Minneapolis-St. Paul radiator shops was high, with many workers exceeding safe levels. This study investigated the prevalence of lead exposure and toxicity in the industry.
Area of Science:
- Occupational Health
- Environmental Health
- Toxicology
Background:
- In 1986, ambient air lead levels in Minneapolis-St. Paul radiator repair shops frequently exceeded Occupational Safety and Health Administration (OSHA) action levels.
- This indicated a potential risk of lead exposure for workers in this industry.
Purpose of the Study:
- To determine the prevalence of lead exposure and toxicity among workers in the radiator repair industry.
- To assess blood lead levels and zinc protoporphyrin (ZPP) levels in this occupational group.
Main Methods:
- Thirty-five radiator shops were identified, and 30 were visited.
- Fifty-three workers from these shops participated in the study.
- Blood lead levels and zinc protoporphyrin (ZPP) levels were measured.
Main Results:
- The mean blood lead level among studied workers was 1.53 mumol/L (range 0.24-2.80 mumol/L).
- Seventeen workers (approximately 32%) had blood lead levels exceeding 1.93 mumol/L (40 micrograms/dl).
- The mean zinc protoporphyrin (ZPP) level was 0.55 mumol/L (range 0.16-1.43 mumol/L).
Conclusions:
- A significant portion of radiator repair workers in the Minneapolis-St. Paul area exhibited elevated blood lead levels.
- No specific worksite or personal characteristic strongly predicted lead or ZPP levels, suggesting widespread exposure risks.
- Further investigation into exposure sources and control measures is warranted.
