In addition to heavy metal contamination, it is also crucial to consider the presence of other contaminants such as pesticides, herbicides, and other chemical pollutants in plant-based products. These contaminants can accumulate in plants during the phytoremediation process and could pose a health risk if consumed by humans. Therefore, it is important to conduct thorough testing and analysis of plant-based products to ensure that they meet safety standards and guidelines set by regulatory authorities.
Furthermore, it is important to consider the potential for allergens in plant-based products, as certain individuals may have sensitivities or allergies to certain plants or plant products. Labeling requirements and transparency about the origin and processing of plant-based products are essential to inform consumers about potential allergens and ensure the safety of these products. By following safety standards and guidelines, monitoring heavy metal levels, and testing for contaminants and allergens, phytoremediation can be a safe and effective method for remediation of contaminated sites while also ensuring the safety of plant-based products for human consumption.
While phytoremediation offers numerous advantages over traditional bioremediation technologies, it is essential to ensure the safety of plant-based products for human consumption. The review discusses the safety standards and guidelines that need to be considered when assessing the safety of plant-based products, such as the Dietary Reference Intake (DRI), Recommended Dietary Allowance (RDA), Tolerable Upper Intake Level (TUL), and Maximum Level of Intake without Detriment to Health (MLI). The review also highlights the importance of monitoring heavy metal levels in plant extracts or products to account for potential contamination during processing.
