The potential of wild vegetation species of Eleusine indica L., and Sonchus arvensis L. for phytoremediation of Cd-contaminated soil

Abstract

Phytoremediation has been intensively studied due its costs effectiveness and environmentally sound. Studies of heavy metal pollution phytoremediation has been done in develop countries, but still limited in Indonesia. This study aims to explore the potential of wild plant species Eleusine indica L. and Sonchus arvensis L. as an agent of phytoremediation on Cd-contaminated soil. This study was done descriptively in Pujon, Malang, Indonesia, to test the ability of two species of wild plants E. indica and S. arvensis in absorbing Cd. Along this research, plant growth and the concentration of Cd in roots, stems and leaves, was monitored. Plant growth was measured every week for three months. The plant roots, stems, and leaves collected separately, then analyzed its Cd levels. The results showed that both of two species of wild plants grew well on soil contaminated Cd. Plant roots can accumulate higher Cd than the stem part. In addition, E indica has the ability to accumulate Cd higher than S. arvensis, i.e. 57.11% and 35.84%, respectively.

Bioaccumulation and Translocation of 6:2 Fluorotelomer Sulfonate, GenX, and Perfluoroalkyl Acids by Urban Spontaneous Plants

“…These four plants are common urban weeds in China, and plants of the same families span a wide geographic range across global urban spaces. In addition, they possess significantly different morphological and physiological traits (Table S2 and Figure S2A–J) and have demonstrated superenrichment of heavy metals in previous studies. − The experiments were conducted in five replicates in a greenhouse (25 °C, 14 h light). Plants were collected from the campus of Chongqing University (Shapingba District, Chongqing, China), and no source of industrial pollution (e.g., factories) within 10 km was confirmed.…”

“…Furthermore, they have been shown to have promising applications in urban restoration practices. In fact, many of them can grow well under postmining site conditions, and they can serve as a good option in urban greening initiatives within polluted areas to develop species-rich plant communities and accumulate heavy metal pollutants. − …”

The influence of rice husk and tobacco waste biochars on soil quality

“…Based on the previous research conducted by Hamzah et al (2017), this study site has been contaminated with heavy metals, such as lead and mercury. This study consisted of three steps, (1) biochar preparation and characterization, (2) soil sampling and characterization; and (3) field experiment.…”

Phytobioremediation of cadmium-contaminated soil using combination of Ipomoea reptans Poir and Trichoderma sp. and its effect on spinach growth and yield

“…It is suspected that the lower the concentration of Cd contained in the soil, the less absorbed content and this does not cause toxics to the plant. According to Hamzah et al, (2017), the existence of Cd in the soil at high concentration that exceeds a threshold generally can inhibit plant growth; cadmium will restrict the plant growth and change the plant structure. (Table 7).…”
