Input assumptions used to calculate non-carcinogenic human health risk due to different trace metal exposures through dietary intake of brinjal and dermal adsorption of soils.
| Parameter | Unit | Values | Reference | |
|---|---|---|---|---|
| Ingestion | Dermal adsorption | |||
| Metal concentration (Cbrinjal and Csoil) | µg g-1 | – | – | – |
| Brinjal ingestion rate (BIR) | g person-1 day-1 | 7.28 | – | 24,25 |
| Skin surface area available for contact (SA) | cm2 | – | 5700 | 23 |
| Dermal absorption fraction (ABSd) for metals | – | – | 0.001 | 23,26 |
| Adherence factor of soil to skin (AF) | mg cm-2-event | – | 0.07 | 23 |
| Exposure frequency (EF) | Days year-1 | 365 | 350 | 23 |
| Exposure duration (ED)* | Year | Male = 64.8; Female = 67.8 | 30 | 23,24 |
| Conversion factor (CF) | kg mg-1 | – | 10–6 | 23 |
| Average body weight (BW) | kg | Male = 70; Female = 50 | Male = 70; Female = 50 | 24 |
| Event frequency (EV) | (events day-1) | – | 1 | 23 |
| Averaging time (AT) | Days | Male = 23,652; Female = 24,747 | 10,950 & 25,550 days for non-carcinogenic and carcinogenic effects, respectively | 23,24 |
*ED is calculated by deducing the childhood period of 6 years from the total life expectancy.
