The Availability Heuristic01:08

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Area of Science:

  • Analytical Chemistry
  • Environmental Science

Context:

  • Ethylene oxide (EO) is a widely used industrial chemical with significant toxicological and environmental implications.
  • Accurate quantification of EO in various matrices is crucial for safety monitoring and regulatory compliance.

Purpose:

  • To develop and compare two distinct analytical methods for the determination of ethylene oxide in aqueous extracts.
  • To evaluate the reliability and applicability of gas-liquid chromatography and spectrophotometry for EO quantification.

Summary:

  • Ethylene oxide is extracted via water circulation at 37°C in a closed system.
  • Quantification is achieved using either gas-liquid chromatography (GLC) with propylene oxide as an internal standard or a spectrophotometric method involving periodate oxidation and chromotropic acid determination of formaldehyde.

  • The spectrophotometric method, while longer, involves acid hydrolysis to differentiate between ethylene glycol and formaldehyde, with the difference in absorbance indicating EO concentration.

    • Impact:

    • Provides validated analytical techniques for accurate ethylene oxide measurement.
    • Offers researchers and industrial hygienists a choice of methods based on equipment availability and sample throughput.
    • Contributes to improved safety protocols and environmental monitoring related to ethylene oxide exposure.
