“…EF represents exposure frequency (350 d·a −1 ); ED means exposure duration (The ED values for adults were 30 years, respectively) [ 32 ]; IR is the inhalation rate; the average daily intakes of vegetables for adult inhabitants were 0.345 kg·d −1 and the average daily intakes of rice for adult inhabitants were 0.221 kg·d −1 [ 33 , 34 ]; C is the metal concentration in the vegetable samples (mg·kg −1 ); BW = average body weight set to 70 kg for adults [ 35 ]; AT is averaging time for non-carcinogens: 365 × EDd (taken as 30 years for non-carcinogens and 70 years for carcinogens) [ 36 ].…”

With the rapid development of industry, chromium (Cr) pollutants accumulate constantly in the soil, causing severe soil Cr pollution problems. Farmland Cr pollution hurts the safety of agricultural production and indirectly affects human health and safety. However, the current situation of Cr pollution in farmland soil and crops has not been detailed enough. In this study, the evaluation of Cr potential risk in soil-crop systems was conducted in a rural area that was affected by industry and historic sewage irrigation. Ten different crops and rhizosphere soils were sampled from four fields. The results showed that Cr contents in farmland soil exceeded the national standard threshold in China (>21.85%), and the Cr content in edible parts of some agricultural products exceeded that too. According to the PCA and relation analysis, the Cr accumulation in edible parts showed a significant correlation with soil Cr contents and available potassium contents. Except for water spinach, the target hazard quotient (THQ) of the other crops was lower than 1.0 but the carcinogenic health risks all exceeded the limits. The carcinogenic risks (CR) of different types of crops are food crops > legume crops > leafy vegetable crops and root-tuber crops. A comprehensive assessment revealed that planting water spinach in this area had the highest potential risk of Cr pollution. This study provided a scientific and reliable approach by integrating soil environmental quality and agricultural product security, which helps evaluate the potential risk of Cr in arable land more efficiently and lays technical guidelines for local agricultural production safety.
