Indoor Air Pollution And Pulmonary Function Growth In Pre-Adolescent Children - (1986)

Indoor Air Pollution and Pulmonary Function Growth in Preadolescent Children: Legal Implications for Asbestos-Related Cases

Abstract

The study "Indoor Air Pollution and Pulmonary Function Growth in Preadolescent Children" by Catherine S. Berkey, James H. Ware, Douglas W. Dockery, Benjamin G. Ferris, Jr., and Frank E. Speizer, published in the American Journal of Epidemiology (1986), examines the impact of indoor air pollutants, such as sidestream cigarette smoke and gas stove emissions, on the pulmonary function growth of children aged 6 to 10. The researchers analyzed data from 7,834 children across six geographic areas in the United States, focusing on forced expiratory volume (FEV1) and forced vital capacity (FVC) as measures of lung function. The study found that exposure to these pollutants was associated with reduced pulmonary function growth, with cumulative effects over time. These findings underscore the long-term health risks of early environmental exposures.

Legal Relevance

This study provides a foundation for legal arguments in asbestos-related cases by emphasizing the cumulative and lasting impact of early environmental exposures on lung health. While the study focuses on indoor air pollution, its findings can be extrapolated to support claims involving asbestos exposure. Key points include:

• Evidence Pathways: The study demonstrates how early exposure to harmful substances can lead to long-term deficits in lung function, supporting claims that asbestos exposure, even at low levels or during childhood, can have significant health consequences.
• Occupational History Relevance: The findings highlight the importance of documenting exposure history, as cumulative damage from environmental pollutants can predispose individuals to chronic respiratory diseases.
• Counterarguments to Defense Claims: The study counters common defense arguments that minimal or early-life asbestos exposure is unlikely to cause harm by showing that even low-level exposures can have lasting effects on lung development.

Occupation Groups at Risk

While this study does not directly address occupational asbestos exposure, its findings are relevant to individuals in high-risk occupations where asbestos exposure is common. These include:

• Construction Workers: Often exposed to asbestos in insulation, roofing, and cement products.
• Shipyard Workers: Frequently encounter asbestos in shipbuilding materials.
• Industrial Workers: Exposed to asbestos in manufacturing and machinery.
• Firefighters: Risk exposure during building demolitions or fires involving asbestos-containing materials.
• Miners: Particularly those working in asbestos mines or areas with naturally occurring asbestos.

The study’s emphasis on cumulative lung damage reinforces the need for protective measures and accountability in these industries.

Current Medical Understanding

The study aligns with current medical knowledge that early exposure to harmful substances, including asbestos, can lead to long-term respiratory issues. It supports the understanding that cumulative damage to lung function can predispose individuals to diseases such as asbestosis, mesothelioma, and lung cancer. However, the study’s reliance on self-reported data and a relatively short follow-up period may limit its generalizability.
