ASTM D4861

ASTM D4861 is the standard practice for sampling and selection of analytical techniques for pesticides and polychlorinated biphenyls in air. It provides a structured approach for collecting air samples and choosing suitable analytical methods when evaluating these target compounds. For laboratories, consultants, and environmental teams, this standard helps support more consistent sampling decisions and more defensible analytical work. Using ASTM D4861 can improve comparability, reduce uncertainty, and align project procedures with a recognized technical document.

What is ASTM D4861?

ASTM D4861 is an ASTM standard practice focused on how to sample air and how to select analytical techniques for pesticides and polychlorinated biphenyls, or PCBs, in air. Rather than defining a single test method, it helps guide the workflow from sampling through analysis so the chosen approach fits the monitoring objective. This makes the standard useful when selecting methods for environmental assessment, laboratory planning, and technical review. ASTM D4861 is intended to support consistent decision-making in air-related contaminant evaluation.

Where is ASTM D4861 used?

This standard is commonly used in environmental sampling and analytical programs involving air monitoring for pesticides and PCBs. It is relevant when personnel need to collect representative air samples and choose an analytical technique suited to the target compounds and project requirements. Typical use includes laboratory method selection, field sampling planning, and review of air-quality data generated for contaminant evaluation. ASTM D4861 is especially useful where consistent procedures and clear technical documentation are important.

Why is ASTM D4861 important?

ASTM D4861 matters because sampling and method selection directly affect the reliability of air data for pesticides and PCBs. A clear practice helps improve consistency across projects, supports quality control, and reduces the chance of mismatched sampling or analysis choices. It also aids procurement and compliance efforts by giving teams a recognized reference for technical planning. In practice, this can make environmental results easier to compare, review, and defend.
