Poliovirus distribution in the soil-plant system under reuse of secondary wastewater

Treated domestic wastewater is a source of water utilized for a variety of purposes. Outdoor experiments were conducted to examine poliovirus penetration into tomato plants under subsurface drip irrigation with secondary level treated domestic wastewater. According to the results, high virus content in the applied wastewater resulted in a limited penetration into the plant via the roots. No virus contamination was found in the leaves of plants irrigated with wastewater spiked with viruses, while a limited amount of virus contamination was detected in leaves of plants irrigated with tap water enriched with poliovirus.
