“…Thus, this indicated that in comparison, Ipomoea reptans is a more hyperaccumulative plant than Helianthus annuus for the accumulation of Al. Hyperaccumulative plants was reported to be more adaptable to toxic environment than the non-hyperaccumulative [11,12]. Therefore, Al was found higher in Ipomoea reptans than in Helianthus annuus as Al has been reported to be commonly accumulated in the root rather than other parts of the plants [13].…”

Heavy metals contaminations are among the most hazardous environmental pollution due to its ability to resist disintegration in the natural ecosystem. Thus, they pose risk to living organisms as they are persistent in the environment. Reports on the accumulations of heavy metal in edible plants had alarmed many parties that the general public has become more aware on the seriousness of this issue. Bioaccumulation within the food chain poses potential risks of toxicity effects. Thus, it is crucial to conduct appropriate study to analyze the pathway of the heavy metal elements as a measure to understand the behavior of the heavy metal elements. The aim of this paper is to investigate heavy metal accumulation in plant tissue, particularly the leave, stem and root. Ipomoea reptans and Helianthus annuus were selected as the experimental plant species in the study. Spent dry cell or batteries were utilized as the source of heavy metal contamination of which batteries are commonly discarded in the municipal solid waste stream. Results indicated that the accumulation of heavy metals in the two plants were low and below the limit of European Union Standard for edible plants. However, heavy metal in alkaline batteries exposure was found to promote the growth of longer root in both plants as compared to carbon-zinc batteries and the control. Yet, the accumulation of heavy metal in the plants tissues in this study were only monitored for the period based on the maturation of the plants, longer exposure may result with different outcome, that further investigation is deemed necessary.

“…Cyphomandra betacea is a commercially attractive fruit, which distributes in New Zealand, Sri Lanka, and Southwest of China [6]. In this study, to study effects of hyperaccumulator straw on soil nutrient availability and soil enzyme activity of C. betacea under Cd stress, we planted C. betacea seedlings in Cd-contaminated soil, and mulching with straws of four Cd-hyperaccumulator species (Solanum photeinocarpum [7], Tagetes erecta [8], Galinsoga parviflora [9] and Bidens pilosa [10] on soil surface. The aim of the study was to screen hyperaccumulator straw which could enhance soil nutrient availability and soil enzyme activity of C. betacea under Cd stress, and provide a reference for other fruit trees.…”

A pot experiment was conducted to study the effects of hyperaccumulator straw on soil nutrient availability and soil enzyme activities of Cyphomandra beracea under Cadmium (Cd) stress. Four Cd-hyperaccumulator species (Solanum photeinocarpum, Tagetes erecta, Galinsoga parviflora, Bidens pilosa) straws were applied as mulches on the Cd-contaminated soil surface which planted C. beracea. The results showed that mulching hyperaccumulator
