In order to effectively decrease cadmium (Cd) in rice grains contaminated paddy soil and maintain the safe production of rice, identifying excessive Cd caused by varieties or is critical, but it currently lacking. present study, ethylenediaminetetraacetic acid (EDTA)-extractable (EDTA-Cd) bioaccumulation factors based on EDTA-Cd (BCFEDTA-Cd) were used develop an approach identify Cd. Based empirical soil–plant transfer model species sensitivity distribution (SSD), BCFEDTA-Cd divided into five grades. The results showed that grades (minimum value less than 0.11 mg/kg maximum greater 2.93 mg/kg) 0.09 1.40) classified normal pH range. Further, conversion equation between diethylene triamine pentaacetic (DTPA)-Cd was obtained through linear regression analysis using 67 sets data from literature. addition, four selected rounding thresholds for percentage total (%) 52.5, 67.5, 82.5, 97.5%. A (about 75%) can be status bioavailability, especially with high background Finally, a set 1084 pairs Cd-contaminated soils investigate respective contributions when exceeds limit (0.2 mg/kg). field experiment data, systematic identification causes exceeding limit, variety, established applied. conclusion, under exposure conditions, importance identified, their distinguished, thus helping contamination rice.

Cadmium poses a significant threat to freshwater aquatic organisms and ecosystems, making it essential establish regional quality criteria (FWQC) in China safeguard these organisms. The toxicity database for cadmium covered 249 acute data from 52 species (seven phyla 27 families) 62 chronic 21 (four 12 families). During short-term exposure, Morone saxatilis displayed the most sensitivity cadmium, whereas Daphnia magna showed long-term exposure scenarios. Significant correlations were identified between water hardness with coefficient (KATD) at 1.0227 (n = 52, p < 0.05) (KCTD) 0.4983 21, 0.05). With distribution method, (S-FWQC) derived normal as best fit (R2 0.9793), while (L-FWQC) calculated using logistic 0.9686). formulas S-FWQC L-FWQC represented 10(1.0227×lg(H)−1.5444) 10(0.4983×lg(H)−1.7549), respectively, serving an independent variable. This study offers valuable insights improving management of protect China.
