Phytoremediation Capability and Copper Uptake of Maize (Zea mays L.) in Copper Contaminated Soils

Copper is a frequently used heavy metal worldwide and known to be an essential micronutrient for most living organisms including plants. However, excessive levels of copper in soil may adversely affect plant growth survival. The continuing introduction soil, e.g., through utilization agrochemicals has raised serious environmental concerns throughout the world. A variety plants have capability eliminate pollutants from different mechanisms; however, limited information reported on phytoremediation potential maize (Zea mays L.) its uptake accumulation copper-containing soils. effects additions 0, 50, 100, 200 300 mg kg?1 parameters Z. mays, roots shoots, were investigated this research. content samples determined using atomic absorption spectrophotometry. addition 50 Cu stimulated parameters, while higher exhibited inhibitory growth. Results indicated that accumulated significantly than shoots all treatments, suggesting dominancy phytostabilization mechanism remediation Cu-polluted by mays. translocation aerial parts enhanced some extent with level soil. greatest capacity 5210 µg per pot was gained cultivated treated copper. demonstrated can promisingly remediate low moderately copper-contaminated
