Potentially Toxic Metals in the High-Biomass Non-Hyperaccumulating Plant : Human Health Risks and Phytoremediation Potentials.

Human health risk and phytoremediation of potentially toxic metals (PTMs) in the edible vegetables have been widely discussed recently. This study aimed to determine the concentrations of four PTMs, namely Cd, Fe, Ni, and Zn) in Amaranthus viridis (leaves, stems, and roots) collected from 11 sampling sites in Peninsular Malaysia and to assess their human health risk (HHR). In general, the metal levels followed the order: roots > stems > leaves.

Growth and health status of reared under manipulated photoperiod conditions.

In general, the length of photoperiod affects the physiology of . This study aimed to understand the growth and health status of this fish reared under manipulated photoperiods. The study was conducted between June to August 2020[A1] .

Anthropogenic impacts on heavy metal concentrations in the coastal sediments of Dumai, Indonesia.

Concentrations of Cd, Cu, Pb, Zn, Ni and Fe were determined in the surface sediments to investigate the distributions, concentrations and the pollution status of heavy metals in Dumai coastal waters. Sediment samples from 23 stations, representing 5 different site groups of eastern, central and western Dumai and southern and northern Rupat Island, were collected in May 2005. The results showed that heavy metal concentrations (in microg/g dry weight; Fe in %) were 0.
