Threshold limit value − time-weighted average (TLV-TWA): The average exposure on the basis of a 8 hours per day, 40 hours per week work schedule. Threshold limit value − short-term exposure limit (TLV-STEL): A 15-minute TWA exposure that should not be exceeded at any time during a workday, even if the 8-hour TWA is within the TLV-TWA.
In addition ECx values do depend on the exposure time. [7] ECx values for survival decrease for increasing exposure time, until equilibrium has been established. This is because effects depend on internal concentrations, [8] and that it takes time for the compound to penetrate the body of test organisms. However, sub-lethal endpoints (e.g ...
