Pneumoproteins in Offshore Drill Floor Workers

Area of Science:

• Occupational Health
• Environmental Medicine
• Biomarkers

Background:

• Occupational exposure to airborne contaminants in offshore drilling environments poses potential respiratory health risks.
• Systemic inflammation and lung injury biomarkers are crucial for assessing health impacts in exposed workers.

Purpose of the Study:

• To evaluate serum levels of club cell protein 16 (CC-16), surfactant protein D (SP-D), and C-reactive protein (CRP) in offshore drill floor workers.
• To investigate the influence of airborne contaminants and smoking status on these biomarkers.

Main Methods:

• Blood samples collected pre- and post-14-day work shifts from 65 drill workers and 65 referents.
• Air sampling for oil mist, drilling mud, and elemental carbon.
• Analysis of serum CC-16, SP-D, CRP, and smoking biomarkers (nicotine, cotinine).

Main Results:

• No significant changes in CC-16 or SP-D levels during the work period or between workers and referents.
• CRP levels decreased over the work period.
• CC-16 concentrations showed a strong association with sampling time; current smokers with high nicotine levels had lower CC-16.

Conclusions:

• A 14-day offshore work period did not alter serum pneumoprotein or CRP levels.
• Sampling time significantly impacts CC-16 measurements.
• Smoking status, specifically nicotine levels, influences CC-16 concentrations in drill workers.
