| #P001 | chemical | health | guideline | chlorpyrifos | drinking water | MAC | 0.09 mg/L | The maximum acceptable concentration (MAC) for chlorpyrifos in drinking water is derived from the ADI as follows: MAC = 0.01 mg/kg bw per day × 70 kg × 0.20 / 1.5 L/d ≈ 0.09 mg/L | high | |
| #P002 | chemical | health | guideline | chlorpyrifos (ADI) | drinking water | requirement | 0.01 mg/kg bw per day | The ADI for chlorpyrifos has been derived by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) as follows: ADI = 0.1 mg/kg bw per day / 10 = 0.01 mg/kg bw per day | Derived by FAO/WHO using an uncertainty factor of 10 | high |
| #P003 | chemical | health | guideline | chlorpyrifos (NOAEL) | drinking water | unknown | 0.1 mg/kg bw per day | 0.1 mg/kg bw per day is the NOAEL derived from two-year studies in the dog and rat and studies with human volunteers | Derived from two-year studies in the dog and rat and studies with human volunteers | high |
| #P004 | design | operational | guideline | average body weight (adult) | drinking water | requirement | 70 kg | 70 kg is the average body weight of an adult | Used for MAC derivation | high |
| #P005 | design | operational | guideline | average daily consumption of drinking water (adult) | drinking water | requirement | 1.5 L/d | 1.5 L/d is the average daily consumption of drinking water for an adult. | Used for MAC derivation | high |
| #P006 | design | operational | guideline | proportion of daily intake allocated to drinking water | drinking water | requirement | 0.20 dimensionless | 0.20 is the proportion of daily intake of chlorpyrifos allocated to drinking water | Used for MAC derivation | high |
| #P007 | design | operational | guideline | uncertainty factor | drinking water | requirement | 10 dimensionless | 10 is the uncertainty factor. | Used for ADI derivation | high |
