Relative arsenic intake dose decreased in order: water > garden
soils > homegrown vegetables, and on average, each accounted for 77, 16, and 7% of a residential gardener's
daily arsenic intake dose. The IELCR ranges for vegetables, garden soils, and water were 10−8 to 10−4, 10−6
to 10−4, and 10−5 to 10−2, respectively. All vegetables (greenhouse and home garden) were grouped by
scientific family, and the risk posed decreased as: Asteraceae ≫ Fabaceae > Amaranthaceae >
Liliaceae > Brassicaceae > Solanaceae ≫ Cucurbitaceae.
