Accumulation of these pollutants in soil is becoming a major ecological concern because of their adverse effects on food safety and human health 8. Soil contamination by HMs and PAHs has accelerated owing to rapid social and economic development in China through urbanization and industrialization 6, 7. It has been estimated that 25% of global soils are highly degraded, 44% are moderately degraded, and more soil is degraded every day 5. These contaminants are often generated by various agricultural and industrial products and practices, such as chemical fertilizers, burning of fossil fuel, petroleum spills, coal tar, and residues from metalliferous mining 3, 4. Similar content being viewed by othersĬontamination with heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) is one of the most pressing threats to water and soil resources, as well as to human health it can destroy natural ecosystems 1, 2. calamus might be useful for phytoremediation of co-contaminated soil. Cluster analysis was used to evaluate the similarity between different treatments during phytoremediation of Cd and PAHs. Correlation analysis also indicated a positive relationship between residual concentrations of phenantherene and pyrene (PAHs), whereas enzyme activities (dehydrogenase and polyphenol oxidase) were negatively correlated with each other. Dissipation of PAHs from soils was not significantly influenced by Cd addition or by the presence of plants. The combined treatment of low Cd and low PAHs increased plant biomass and Cd accumulation in plant tissues, thus enhancing Cd removal. calamus were significantly influenced by the interaction of Cd and PAHs after 60 days of growth. Our results showed that growth and biomass of A. A greenhouse experiment was conducted to investigate the independent and interactive effects of cadmium (Cd) and polycyclic aromatic hydrocarbons (PAHs) on the growth of the wetland plant Acorus calamus and its ability to uptake, accumulate, and remove pollutants from soils. Phytoremediation is a promising technology for the remediation of sites co-contaminated with inorganic (heavy metal) and organic pollutants.
