Abstract

Increasing urbanization and industrialization have led to serious heavy metal pollution problems, detrimental to the environment and human health. Phytoremediation, which utilizes hyperaccumulator plants such as Indian mustard and water hyacinth, presents an efficient and sustainable alternative. Despite having the advantages of low cost and utilization of renewable natural resources, phytoremediation also carries risks, such as contamination of consumable plant parts and limited efficiency. Therefore, selecting the right hyperaccumulator plants and having an in-depth understanding of phytoremediation mechanisms are the keys to increasing their success. Phytoremediation mechanisms, such as phytoextraction, hemofiltration, and phytostabilization, can be implemented by considering environmental conditions and contaminants. Factors such as the nature of the medium, root zone, and environmental conditions play a crucial role in determining the effectiveness of phytoremediation. Although challenges still exist, phytoremediation remains a promising approach to treating heavy metal pollution in an economical and environmentally friendly manner.

Abstract

The rapid growth of the chemical industry has increased liquid waste containing heavy metals (Cadmium, Zinc, Lead), which threaten ecosystems and human health due to persistence and biomagnification. The handling of these effluents requires specific methods according to the characteristics of the effluents. Electrochemical processes stand out in heavy metal removal efficiency, while adsorption using natural materials (fruit peels, sawdust) offers lowcost effectiveness. Ion flotation utilizes surfactants, although its efficiency depends on operational conditions. Chemical precipitation with lime is a cheap solution to reduce metal solubility, while phytoremediation relies on plants as an environmentally friendly alternative. The selection of methods is based on the type of metal, waste concentration, and economic-environmental factors. The implementation of this appropriate technology is expected to minimize the risk of heavy metal pollution in a sustainable manner.
