The workshop will discuss measuring and interpreting exposure data in occupational settings.

Mar 25, 2026

Presentations are invited for ASTM International’s 45th Workshop on Detection Limits and Censoring Data in Workplace Exposure Assessment, to be held Oct. 8, 2026, in Jacksonville, FL. The event is sponsored by ASTM International’s air quality committee (D22) and will be held in conjunction with the committee’s standards development meetings.

The workshop will discuss the challenges and methodologies associated with measuring and interpreting exposure data in occupational settings. Exposure data primarily represents the level of exposure to hazardous substances in the workplace. Conditions like the use of an exhaust system, technical parameters, or even humidity and temperature can influence this measure.

Attendees will:

• Gain a deeper understanding of the importance of detection limits and overall method uncertainty in workplace measurements, how they are calculated, and their influence on data interpretation and risk assessments;
• Explore various methodologies for handling censored data and provide tools and statistical approaches for drawing valid conclusions from incomplete datasets;
• Learn about the latest research trends and emerging technologies to help them identify critical issues;
• Leave equipped with new knowledge, tools, and connections to effectively enhance assessment practices.

Topics for this workshop include:

• Detection and quantification limits 
• Factors influencing detection limits (analytical and statistical methodology, instrument calibration, and sample preparation)
• Measurement uncertainty, i.e., the accuracy of exposure measurement
• Data censoring, i.e. discerning which data is suitable for an assessment
• Interpretation of censored data in exposure studies
• Considerations in data collection
• Needs for new or improved standards

To participate in the workshop, authors must submit a 250 to 300-word preliminary abstract to the Workshop Chairs, Steven Verpaele and Katrin Pitzke no later than May 31, 2026.
