A methodology for identifying workers exposed to asbestos since 1940

Area of Science:

• Occupational Health
• Environmental Health
• Epidemiology

Background:

• Asbestos exposure poses significant health risks, necessitating accurate identification of exposed populations.
• Historical industrial practices have led to widespread asbestos use in various workplaces.
• Quantifying asbestos exposure is crucial for public health assessments and risk management.

Purpose of the Study:

• To develop and apply a method for identifying specific workplaces with high asbestos exposure.
• To estimate the total number of individuals with substantial asbestos exposure in New Jersey.
• To categorize exposed individuals by industry sector.

Main Methods:

• Utilized a novel methodology to pinpoint individual workplaces associated with asbestos use.
• Collected and analyzed data on employee numbers at identified high-risk locations.
• Segmented exposure data by industry, including manufacturing plants, shipyards, and insulators.

Main Results:

• Estimated 486,400 individuals in New Jersey experienced substantial asbestos exposure.
• Identified 16 manufacturing plants contributing 102,700 exposed individuals.
• Eight shipyards accounted for 376,200 exposed individuals, with 7,500 insulators also identified.

Conclusions:

• The developed method effectively identifies high-risk workplaces and quantifies asbestos-exposed populations.
• Shipyards and manufacturing plants represent major sources of asbestos exposure in New Jersey.
• Findings underscore the long-term public health burden of occupational asbestos exposure.
