Research Project: Investigation into Effect of Soil Moisture Depletion on Vegetable Crop Uptake of Microcontamination Under Recycled Water Irrigation.

Location: Water Management and Conservation Research

Project Number: 2020-13000-003-01-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Jan 1, 2011
End Date: Dec 31, 2015

Reclaimed wastewater has been increasingly used for irrigation throughout the world, but questions remain about potential public health risks. The accumulation of emerging contaminants in crops has been proposed but no data exists regarding the uptake of these compounds by crops consumed fresh by humans.

Greenhouse experiments will be conducted to determine the potential for 4 compounds found in treated effluent to accumulate in crops eaten fresh. The compounds selected are carbamazepine, lincomycin, ibuprofen, and caffeine. Crops will be irrigated with the known concentrations of the compounds irrigated at different soil moisture depletions. Concentrations of the compounds will be determined from the edible portions of the crops. Documents Reimbursable with U of HI (AFRI). Log 42145.
