“…The higher content may be due to soil uptake from the farm soils or adherence from high traffic volume, or contamination from industrial activities, or both. Earlier reports have shown that cadmium uptake as a result of the use of untreated domestic sewage and super phosphate fertilisers to fertilise plants accounted for about 69-94% of such contaminants, and the remainder arising from atmospheric deposition (Harrison & Chirgawi, 1989). A relationship has also been established between lead content of street foods and volume of vehicular traffic (Ologunde & Abiona, 2000), and lead content of selected food samples obtained from underdeveloped and developing areas were found to be in increasing order (Krelowska -Kulas, 1988).…”

A study was carried out on the processing of a locally produced 'robo' from melon seeds in the Abeokuta metropolis in order to identify potential hazards and critical control points associated with its production and the measures to be adopted for the control of associated hazards. Samples collected along processing lines were subjected to physical and chemical hazard analysis. The results of the analysis showed that the samples were contaminated with the following hazards: mineral matter, tramp metal, extraneous vegetable material and matter of animal origin, as well as lead, cadmium, arsenic and tin (0.33 ± 03, 1.36 ± 0.02, 0.34 ± 0.00 and 1.24 ± 0.03 mg kg )1 , respectively) which were still higher than the acceptable limits (0.1 mg kg )1 ).

“…The main route for Cd to enter plants is through the roots absorbing Cd from soil or water, or the leaves absorbing Cd from the atmosphere [22,23]. Under Cd stress, plants exhibit a series of physiological responses to detoxification and heavy metal enrichment.…”

“…Under Cd stress, plants exhibit a series of physiological responses to detoxification and heavy metal enrichment. Previous studies have shown that the main response mechanisms of plants under Cd stress are root absorption, compartmentalization, chelation, antioxidation, stress, and osmotic regulation [23,24]. Among these, root function, compartmentalization, and chelation of plants are the dominant factors in the process of Cd enrichment.…”

Soil cadmium (Cd) extraction for hyperaccumulators is one of the most important technologies for the remediation of Cd-contaminated farmland soil. However, a phytoremediation model using a single hyperaccumulator cannot guarantee normal agricultural production in contaminated areas. To solve this problem, a combination of efficient remediation and safe production has been developed. Based on two-period field experiments, this study explored the effect of biofortification on soil Cd remediation using the fruit tree Sedum alfredii Hance and oil sunflower crop rotation and relay cropping mode. BioA and BioB treatments could markedly improve the efficiency of Cd extraction and remediation, and the maximum increase in Cd accumulation was 243.29%. When BioB treatment was combined with papaya–S. alfredii and oil sunflower crop rotation and relay cropping mode, the highest soil Cd removal rate in the two periods was 40.84%, whereas the Cd concentration of papaya fruit was lower than safety production standards (0.05 mg/kg). These results demonstrate that biofortification measures can significantly improve the Cd extraction effect of S. alfredii crop rotation and relay cropping restoration modes, which has guiding significance for Cd pollution remediation and safe production in farmland.

“…The main way for Cd to enter plants is to be taken up from the soil or water through the roots of the plant, and it can also be taken up from the atmosphere through the leaves of the plant [ 46 , 47 ]. The uptake of Cd by the roots is mainly divided into two steps.…”

The heavy metal cadmium (Cd), as one of the major environmentally toxic pollutants, has serious impacts on the growth, development, and physiological functions of plants and animals, leading to deterioration of environmental quality and threats to human health. Research on how plants absorb and transport Cd, as well as its enrichment and detoxification mechanisms, is of great significance to the development of phytoremediation technologies for ecological and environmental management. This article summarises the research progress on the enrichment of heavy metal cadmium in plants in recent years, including the uptake, transport, and accumulation of Cd in plants. The role of plant roots, compartmentalisation, chelation, antioxidation, stress, and osmotic adjustment in the process of plant Cd enrichment are discussed. Finally, problems are proposed to provide a more comprehensive theoretical basis for the further application of phytoremediation technology in the field of heavy metal pollution.
