Exposure to PAHs and health risk assessment in three sewage irrigations

The sewage irrigation area in Tianjin reached 6 billion m2 in 2003 which accounts for 22% of the irrigated areas. Polycyclic aromatic hydrocarbons (PAHs) contamination caused by sewage irrigation on agricultural land has attracted considerable attention because of their toxic and hazardous risks to...
