Low-level arsenic exposure in wood processing plants

M J Rosenberg, P J Landrigan, S Crowley

    American Journal of Industrial Medicine
    |January 1, 1980
    PubMed
    Summary

    Workers exposed to arsenic preservatives in wood processing showed increased urinary arsenic levels, indicating a potential exposure hazard. Further research is needed to assess long-term health effects.

    Area of Science:

    • Occupational Health
    • Environmental Toxicology
    • Industrial Hygiene

    Background:

    • Arsenic preservatives are used in wood treatment.
    • Concerns exist regarding potential health risks for workers exposed to these chemicals.

    Purpose of the Study:

    • To evaluate the acute medical hazards associated with arsenic preservatives in wood processing.
    • To assess arsenic exposure levels in workers at wood treatment plants.

    Main Methods:

    • Study involved 44 workers exposed to arsenic preservatives and 37 controls at three California woodworking plants.
    • Data collected included medical histories, physical examinations, and urinary arsenic level analysis.
    • Statistical adjustments were made for age, employment duration, and smoking habits.

    Main Results:

    • No significant differences were found in medical histories or physical examinations between exposed workers and controls.
    • Urinary arsenic concentration directly correlated with the level of arsenic exposure.
    • The study confirmed an arsenic exposure hazard in the wood processing industry.

    Conclusions:

    • Occupational exposure to arsenic preservatives in wood processing presents a demonstrable hazard.
    • While acute toxicity was not evident in this study, the potential for chronic or subtle toxicities remains.
    • Further investigation into long-term health effects, such as neurological deficits, is warranted.
