“…The Cd content in stem vegetables was the highest among the categories of vegetables. Furthermore, celery is suggested to be more capable of accumulating higher Cd levels than other vegetables in other studies [28,29], which is in accordance with the findings in this study. Our results showed that celery, even in the control area, accumulated the highest concentration of Cd among all categories of vegetables investigated.…”

Dietary exposure of cadmium (Cd) has not been studied in Southwest China. The objective of the study was to determine the pollution characteristics and contamination levels in various agriculture products in Southwest China and to conduct a comparison of dietary exposure assessment of Cd in polluted and non-polluted areas. Results showed that the mean Cd contents in rice were 0.53 and 0.52 mg/kg in the high-polluted and low-polluted areas, respectively, with the average value was 0.03 mg/kg in the control area. The mean dietary Cd exposure from rice and vegetables of the selected non-occupational residents in Southwest China was 113.10 μg/kg bodyweight (bw)/month, 88.80 μg/kg bw/month, and 16.50 μg/kg bw/month in the high-polluted, low-polluted, and control areas, respectively, which correspond to 4.5 times, 3.6 times, and 0.66 times of the provisional tolerable monthly intake (25 μg/kg bw/month) established by the Joint FAO/WHO Expert Committee on Food Additives. The findings indicated that the risk for Cd exposure of residents was high due to home-grown food (most especially rice) being near polluted areas and is of great concern.

“…The uptake effect of plants is one of the major pathways through which THMs enter into the food chain from the growth soils. The bioaccumulation factor (BCF) is usually used to reflect the uptake effect and then used to compare the capacity of different plants to absorb pollutants from the growth soils . Based on the uptake effect from growth soils to plants, some linear prediction models for BCF single THM have been established in wheat and corn, vegetables and cultivated soil .…”

BACKGROUND Toxic heavy metals (THMs) cause severe environmental hazards and threaten human health through various consumption of food stuff. However, little is known of THMs in chestnuts. In this study, the risk assessment and prediction of THMs [lead (Pb), arsenic (As), chromium (Cr), cadmium (Cd) and mercury (Hg)] in chestnuts and growth soils from China were investigated. RESULTS The main detected THMs in chestnuts and growth soils were As and Cd. The total pollution levels of the five THMs (Nemerow pollution indexes, NPIs) were 0.062 and 1.06, respectively. The dietary risks for children were higher than those of adults, especially short‐term non‐carcinogenic risk. The main combined risks from the relationships between THMs were Pb‐Cr (r = 0.85, P < 0.01) in chestnuts and Pb‐As (r = 0.59, P < 0.01) in growth soils. The risk source was found to be the uptake effect of THMs from soil to chestnut, with the highest bioaccumulation factors (BCFs) of Cd (0.254). Several comprehensive risk models were established with the highest coefficient of determination (R2) of 0.79. In addition, the main contribution rates of different soil parameters to comprehensive risk of THMs uptake were 49.8% (Cd), 23.4% (pH), 13.8% (Cr) and 13.0% (organic carbon). CONCLUSION The total pollution levels of THMs fell outside of the safety domain in growth soils. Furthermore, more attention needs to be paid to Cd pollution owing to its low environment background value and high accumulation ability. Three main soil parameters (Cr content, pH, organic carbon) played important roles in the formations and accumulations of THMs in chestnuts. © 2019 Society of Chemical Industry

“…Soil contamination with cadmium concentrations as high as 2500 mg kg −1 had the objective of evaluating specific phytotoxic effects, such as the onset of chlorosis and plant mortality, which could not be observed in concentrations close to the Brazilian legal limit (3 mg kg −1 ). Moreover, the concentrations of cadmium that were used in this work simulate real cases of severe soil pollution in different areas around the world, as reported for soils from Spain, Poland, and many other countries …”

This study aims to elucidate the retention mechanism of Cd2+ in Chromic Luvisol, quantify the accumulation of this element in coriander (Coriandrum sativum L.), and evaluate the resulting biological disorders. After chemical and structural soil characterization, its maximum adsorptive capacity for Cd2+ is estimated. Subsequently, coriander is cultivated in the presence of Cd (from 12.5 to 2500 mg kg−1); cadmium concentrations are spectrometrically determined in stalks and leaves previously decomposed in a pressurized microwave oven. Leaves are analyzed by optical microscopy to identify cell damage. Chromic Luvisol has 20% (w/w) clay, 0.4 ± 0.03% (w/w) total organic matter, pH 8.0 ± 0.1, maximum adsorptive capacity = 5350 mg kg−1, and discretely reversible Cd2+ adsorption. Coriander exhibits leaf chlorosis and die when soil cadmium doses are ≥625 mg kg−1; below this dose, cadmium is accumulated in coriander up to 22.0 ± 0.6 mg kg−1 (dry weight). At 15 mg kg−1 in soil, cadmium causes atrophy of the mesophyll. This work integrates chemical and biological aspects related to the presence of cadmium in Chromic Luvisol, and highlights the risks concerning the cadmium accumulation in coriander as well as the possibilities of using this vegetable in future phytoremediation investigations.
