“…Finally, 50.0 mg/L is the predicted possible concentration of BPA contained in soil in the future based on current rates of release into the environment, or the amount of BPA in soils suddenly polluted by high concentrations of BPA . In addition, the Cd concentration in soils reportedly varies between 0.01 mg/L and 3.37 mg/L . Moreover, 10.0 mg/L is the predicted possible concentration of Cd accumulated in soils in the future or the concentration of Cd in soils suddenly polluted by high concentrations of Cd .…”

Bisphenol A (BPA) is ubiquitous in the environment because of its continual application in plastics and the epoxy resin industry. Cadmium (Cd) is a highly toxic heavy metal element mainly used in smelting, electroplating, and plastic and dye manufacturing. Pollution as a result of BPA and Cd exists simultaneously in many agricultural regions. However, little information is available regarding the combined effects of BPA and Cd on plants. The combined effects of BPA and Cd on the photosynthesis, chlorophyll fluorescence, and chlorophyll content of soybean seedlings were investigated using noninvasive technology. Combined treatment with 1.5 mg/L BPA and 0.2 mg/L Cd synergistically improved the net photosynthetic rate (Pn ), initial fluorescence (F0 ), maximal photochemical efficiency (Fv /Fm ), effective quantum yield of photosystem II (ΦPSII ), photosynthetic electron transport rate (ETR), and chlorophyll content. Combined treatment with 1.5 mg/L BPA and 3.0 mg/L Cd increased the F0 and decreased the Pn , Fv /Fm , ΦPSII , and ETR, whereas BPA and Cd exhibited an antagonistic effect. Furthermore, combined treatment with 17.2/50.0 mg/L BPA and 3.0/10.0 mg/L Cd synergistically decreased the Pn , Fv /Fm , ΦPSII , ETR, and chlorophyll content, although it increased the F0 . Finally, the effects of BPA and Cd on photosynthesis, chlorophyll fluorescence, and chlorophyll content ceased when BPA stress was stopped.

“…Siswanto et al reported that the degradation of rice residues resulted in the production of high and low molecular organic acids. For instance, the presence of high molecular weight compound like humic acid in the residues decreased the uptake of Cd in the roots on the base of free Cd ion activity and total Cd concentration, whereas low molecular organic acids like citric acid increased the uptake and internalization of Cd .…”

Contamination of soil and water with potentially toxic elements (PTEs) has become a global environmental concern that could pose potential risks to human health and agriculture. The major anthropogenic sources of PTEs contamination include coal combustion processes, leather tanning operations, mining, smelting activities, and use of sewage water for irrigation. Scattered studies are available in the literature that determines the sources, bioavailability, and potential hazards due to PTEs contamination to crop plants and, ultimately, to human beings. This article reviews how solid‐ and solution‐phase chemistry of soil and existing plant species influence the bioavailability of PTEs to cereal and legume plants, along with the mechanisms involved in the uptake and accumulation. This article also describes the phytotoxic effects of PTEs and strategies to overcome these toxic effects by identifying highly tolerant cereals and legumes. Moreover, this article also summarizes recent advances in the field application and discusses perspectives to reduce PTEs accumulation in cereal and legume crops.

“…The concentrations of BPA were designed to reflect those used in earlier investigations of the effect of BPA on terrestrial plants , current BPA pollution level records, developing trends of BPA contamination in the environment, and a hypothetical large accidental release into the environment, and are similar to those selected (1.5 mg/kg, 17.2 mg/kg, 50.0 mg/kg) by Sun et al . The Cd concentrations selected (0.2 mg/kg, 3.0 mg/kg) reflect reported levels in soils, which vary between 0.01 mg/kg and 3.37 mg/kg , and a higher (10.0 mg/kg) concentration that simulates a potential concentration of Cd accumulated in soils in the future or the concentration of BPA in soils suddenly polluted by Cd at high concentration .…”

Bisphenol A (BPA) and cadmium (Cd) pollution exist simultaneously in many regions. However, little information is available regarding the combined effects of BPA and Cd pollution on plants. Plant roots are in direct contact with the soil, which is an important compartment of BPA and Cd. In the present study, the effects of combined BPA and Cd pollution on soybean seedling roots were evaluated in pot experiments. Combined treatment with BPA and Cd at low concentrations (1.5 mg/kg BPA and 0.2 mg/kg Cd) improved soybean seedling root growth. However, other combined BPA and Cd treatments, including combined treatment with BPA (Cd) at the low concentration and Cd (BPA) at the high concentration as well as combined treatment with BPA and Cd at the high concentration, inhibited soybean seedling root growth. The improvement or inhibition of soybean seedling root growth was greater in the combined BPA and Cd treatments than in single treatments. The effects of the combined BPA and Cd treatments on root growth resulted from changes in nitrate assimilation. In addition, the combined effects of BPA and Cd on the nitrate and ammonium contents in roots are discussed. The present research provides a basic understanding of the combined effects of BPA and Cd pollution on plant roots.
