Abstract

Contaminated soils impose a major environmental, agricultural and human health problem worldwide. At present, continuous studies are done to discern potential plants that can be used as a phytoremediant to resolve this problem. The present study investigated the effects on the growth rate, uptake and distribution of the heavy metal on the vegetative parts, tolerance and bioconcentration factor of Abelmoschus esculentus (L.) Moench (okra) to copper-treated soil. Okra seeds were replanted and grown in plastic buckets with soil contaminated with low and high levels of copper. The plant height and dry mass were measured weekly and during harvesting (after eight weeks) respectively; and was then subjected for chemical analysis. The results showed that among the three levels of contamination, high level of copper contaminant caused slow growth and high dry mass in okra plants. High dry mass indicates the tolerance of okra plants against metal contamination and can still be considered viable. The uptake and distribution of copper was greatly present within the roots of the plant, while the leaves accumulated the least. These data showed that as the copper concentration increases, the metal uptake and distribution of plants in their parts also increases. The presence of heavy metal did not affect the biomass production of okra as shown by the high index of tolerance (IT), which exceeded 100% in both levels of metal contamination. Copper exhibited a trend with increasing bioconcentration factor (BCF) values as level of concentration increases which showed that okra can tolerate heavy metal contaminant even at the highest level of contamination. Okra can be a good phytoremediant; however, the metal contaminant may impose physical defects into the plant such as slow growth and shorter height.
