This study investigated the influence of chemical remediation agents (Bc, M, HA, and Bc + HA) on the growth of the halophyte and the mechanism of restoration of soil salinization using joint halophyte and chemical remediation in arid fields. The results showed that aboveground organ biomass of increased significantly with the chemical remediation agents analyze but the effects on the root system were different. Among the root traits, dry weight of the taproot of increased significantly ( < 0.05) by 60.57% with HA; however, the lateral roots were inhibited. With the addition of biochar, the content of sodium ions in roots increased significantly. Further analysis showed that endogenous manganese (Mn) promoted K absorption concentration increase from 22.09 to 38.28 g/kg. Moreover, Joint and chemical remediation with Bc, HA, M and Bc + HA reduced Na to 5854.76, 9396.19, 6530.95 and 11164.29 g/(kg DW⋅m·a), respectively. Tests revealed that for , the aboveground biomass and root morphological plasticity, as well as the synergistic effect of K on Na transport capacity influenced by endogenous Mn in leaves, were the primary causes of the efficient improvement of saline-alkali land.

Tobacco, being a globally cultivated crop, holds significant social and economic importance. Tobacco plants are susceptible to the adverse effects of heavy metals (HMs), particularly cadmium (Cd), which hinders root development, disrupts water balance, and impedes nutrient absorption. Higher concentrations of HMs, especially Cd, naturally accumulate in tobacco leaves due to complex interactions within the plant-soil continuum.

The bromination of α-oxo ketene dithioacetals using KBr/HO, catalyzed by vanadium chloroperoxidase (VCPO), has been successfully demonstrated. A comparative study of enzymatic processes "on water" "in water", using 2 wt% of the surfactant TPGS-750-M revealed that the in-water protocol not only provides higher yields but also accommodates a broader substrate scope. This bromination method in an aqueous micellar medium enabled the preparation of brominated α-oxo ketene dithioacetals in fair to excellent yields (23 examples).

Heavy metals pose a significant threat to human health, with contaminated water sources linked to severe conditions, including gastric cancer. Consequently, the effective remediation of heavy metals is crucial. This study employs a bibliographic analysis to examine key methodologies, leading organizations, and prominent countries involved in heavy metal remediation.

An increasing amount of water pollution is being caused by an increase in industrial activity. Recently, a wide range of methods, including extraction, chemical coagulation, membrane separation, chemical precipitation, adsorption, and ion exchange, have been used to remove heavy metals from aqueous solutions. The adsorption technique is believed to be the most highly effective method for eliminating heavy metals from wastewater among all of them.
