“…The environmental conditions such as geographical location, climate, and soil composition significantly impact the antioxidant content of medicinal plants. For instance, plants grown in regions with abundant sunlight and nutrient-rich soil tend to exhibit higher antioxidant levels [ 54 , 55 ]. Optimal environmental conditions contribute to the synthesis of secondary metabolites, including antioxidants.…”

“…Medicinal plants, known for their rich array of bioactive compounds, including antioxidants, are particularly vulnerable to the adverse effects of environmental pollutants. In addition to affecting the chemical composition, pollution with pesticides and herbicides can contaminate the soil and water, and can also increase the levels of toxic compounds in the medicinal plants [ 5 , 54 ]. When these contaminated plants are consumed, they can cause a range of health problems, including cancer, neurological disorders, and reproductive issues [ 60 , 61 ].…”

“…Soil pollution is a major concern around the world, as it can have a significant impact on human health and the environment. One area where soil pollution can have a particularly significant impact is on medicinal plants, which are valued for their therapeutic properties [ 54 ]. Soil contaminated with heavy metals, industrial chemicals, and pollutants from urban areas ( Figure 2 ) negatively impacts the antioxidant content in medicinal plants [ 67 ].…”

The paper provides a comprehensive examination of heavy metal stress on medicinal plants, focusing on its impact on antioxidant capacity and biosynthetic pathways critical to their therapeutic potential. It explores the complex relationship between heavy metals and the physiological and biochemical responses of medicinal plants, highlighting how metal stress disrupts biosynthetic pathways, altering concentrations of secondary metabolites. This disruption may compromise the overall quality and efficacy of medicinal plants, requiring a holistic understanding of its cumulative impacts. Furthermore, the study discusses the potential of targeted genetic editing to enhance plant resilience against heavy metal stress by manipulating genes associated with antioxidant defenses. This approach represents a promising frontier in safeguarding medicinal plants in metal-contaminated environments. Additionally, the research investigates the role of phytohormone signaling in plant adaptive mechanisms to heavy metal stress, revealing its influence on biochemical and physiological responses, thereby adding complexity to plant adaptation. The study underscores the importance of innovative technologies and global cooperation in protecting medicinal plants’ therapeutic potential and highlights the need for mitigation strategies to address heavy metal contamination effectively.

“…Therefore, in the following manuscript, As will be referred to as a heavy metal. Through soil investigation at eight pollution points in five provinces in southeastern China, it was found that Pb, Ni, and Cd were the main pollutants in industrial sites [4]. Coke/chemical processing and oxygen production in steel plants lead to Pb, Cd and Hg pollution [5].…”

It is very important to understand the distribution and sources of typical potentially toxic elements in industrial sites in order to provide essential information for risk assessment and the process of land reclamation selection. Here, around 29 soil column samples of 6 m depth were collected using a geoprobe drill rig from a typical electroplating site located in the Yangtze River Delta, which has been operating for more than 20 years. Analysis in the laboratory, including measurement of elemental concentrations using ICP-OES, was carried out. The distribution and sources of typical heavy metals were investigated, and correlated risks were assessed using positive matrix factorization. As, Pb, and Cr were the dominant heavy metal pollutants, with ranges of 3.20–154 mg/kg, 13.9–9271 mg/kg, and 27.2–2970 mg/kg, which were 1.28 times, 11.6 times, and 3.71 times higher than the Chinese national standard, respectively. Pb was found to be accumulated in the top 0–2 m and As in the top 0–3 m due to the presence of a typical clay and loamy soil. Additionally, Cr could be transferred into the groundwater, with a maximum concentration of 497 mg/kg, due to frequent interaction between the groundwater and soil. A PMF model showed that the dominant sources of pollution were the electroplating process section, the glass melting process section, the production process section, and the electroplating wastewater. Pb, As, and Cr were mainly generated from the industrial production process, glass melting process, and electroplating process. The pH and CEC appeared to influence the chemical speciation greatly, with higher content observed bound to carbonates as a result of exchange processes in the case of high CEC and low pH conditions. Both the Pb and As observed could contribute to non-carcinogenic and carcinogenic health risks, respectively, based on PMF-HRA analysis, which should receive greater attention in risk management strategies for polluted sites. Identification of the main sources of heavy metals in a site could provide a basis for potential land reclamation.
