Key Findings at a Glance
This section provides a high-level summary of the most critical information regarding wood dust. It serves as an introduction to its classification as a carcinogen and highlights the primary health concerns identified in scientific literature, setting the context for the more detailed sections that follow.
Official Classification
Group 1
Wood dust is classified as a "known human carcinogen" by the International Agency for Research on Cancer (IARC) and the U.S. National Toxicology Program (NTP).
Primary Cancer Risk
Sino-nasal Cancers
The strongest and most consistent evidence links wood dust exposure to cancers of the nasal cavity and paranasal sinuses. Other cancers like lung cancer have also been studied, but the link is less definitive.
Beyond Cancer
Respiratory Issues
Exposure can also lead to non-cancerous health problems, including asthma, bronchitis, dermatitis, and other allergic reactions. These are often the primary complaints from affected communities.
Primary Cancers Associated with Wood Dust Exposure
Understanding the Carcinogenic Risks
This section delves into the scientific evidence linking wood dust to cancer. The interactive chart below allows you to explore how the risk of developing sino-nasal cancer varies significantly across different industries and exposure levels. This highlights that not all wood dust exposure carries the same level of risk, with factors like wood type and work processes playing a crucial role.
Relative Risk of Sino-nasal Cancer by Industry
Odds Ratios (OR) indicate the increased likelihood of disease. An OR of 10 means a 10-fold increased risk.
From Factory Floor to Residential Neighborhoods
While most research focuses on occupational settings, communities living near facilities like mulch production plants also face exposure to airborne wood dust. This section illustrates how "fugitive dust" escapes from these sites and becomes a nuisance and potential health concern for nearby residents, leading to formal complaints and regulatory scrutiny.

Documented Resident Complaints
Oversight and Enforcement
State environmental agencies are responsible for regulating air quality and addressing public nuisances. This section outlines the typical process that follows a resident complaint about fugitive dust. Click on each step to understand its role in the regulatory framework, which aims to balance industrial activity with community well-being.
