For PCDD/F or dioxin-like PCBs, one sampling period of 6 to 8 hours is used.\nType of measurement\nAveraging period\nDefinition\nContinuous\nDaily average\nAverage over a period of one day based on valid hourly or half-hourly averages.\nPeriodic\nAverage over the sampling period\nAverage value of three consecutive measurements of at least 30 minutes each.\nWhere continuous measurement is used, the BAT-AELs may be expressed as daily averages.",
