Microcomputer programs for the evaluation of predictable long-term exposure.

Abstract

Some methods proposed for evaluation of predictable long-term exposure by statistical treatment of workshift exposure values are considered. Predictable long-term exposure is a useful parameter for risk assessment procedures, as it allows the evaluation of workplace hazards by taking into account interday variability of exposure to air contaminants. Statistical calculations required for evaluating predictable long-term exposure may be performed easily by hand-held programmable calculators. The programs reported here are for use with a Texas Instruments TI-59 hand-held programmable calculator equipped with a PC-100 C thermal printer. They are designed for users inexperienced in programming, since an interactive approach has been adopted that helps communication between user and computer.
