“…For instance,Zn 2+ is a cofactor in some essential enzymes in animals and plants, Cu 2+ is an important metal for many biological functions, but at 0.1 to 1.0 mg L -1 is toxic to a number of plants [5]. Nonetheless, some of metals are toxics Pb 2+ is a toxic element, and no useful biological function of lead has been reported [12,13,14,15]. Akrivos et al [16] indicated that zinc (Zn 2+ ), copper (Cu 2+ ), nickel (Ni 2+ ) and chromium (Cr 3+ ) effects on plant growth and crop yields and are known to be cumulative toxins, while lead (Pb 2+ ), cadmium (Cd 2+ ) and mercury (Hg 2+ ) are toxic to the animal or human digest of the plants and might be mutagen causing cancer [17].…”

Abstract:The present study aimed to reuse of ablution water for washing peat soil in order to reduce the concentrations of heavy metals in these soils which might effect negatively on the plant growth. The washing process design was similar to horizontal subsurface flow constructed wetlands (HSSFCW) consist of layers of peat and sand soil and surrounded by gravel on both sides. Strelitzia sp. was used to detect the presence negative effect of the washing process on the morphological characteristics of the plants. The physical and chemical characteristics of ablution water was examined before and after the washing process by using Inductively Couple Plasma-Mass Spectrometer (ICP-MS) Atomic Absorption Spectrometer (AAS). The characteristics of peat soil before and after the washing process were examined by using X-Ray Fluorescence (XRF). The results revealed that the percentage of FeO 3 in peat soil reduced from 45.80 to 1.01%. The percentage of SiO 2 in sand soil dropped from 87.7 to 67.10%. Parameters of ablution water resulted from the washing process which including Biological Oxygen Demand (BOD 5 ) and heavy metals have increased but still within the standard limits for the disposal of ablution water into the environment. No atrophy was observed in Strelitzia sp. leaves, indicating the ability of plant to grow normally. It can be concluded that the utilization of ablution water in the washing of peat soil has improve the characteristics of the soil without effect on their organic constitutes.

“…The maximum removal of K, Ca and N from control sample was less than 10%. The ability of microalgae to accumulate different types of metals ions has been reported in the literature and explained due to the presence of functional groups on the cell wall and cell membrane of microalgae cells which react with metal ions to form complex compounds [31]. Microalgae cells removed metal ions by chemisorption, surface precipitation, ion exchange, and covalent bonding [32].…”

The present study aimed to investigate the potential for application of phycoremediation system using Botryococcus sp. for the treatment of bathroom greywater at village houses. The greywater samples were obtained from four houses. The treatment system was conducted at ambient temperature for 21 days. Botryococcus sp. (Accession No. JQ585723.1) was inoculated into the greywater in a dry mass (0.3 mg L -1 ). The results revealed high effectiveness of the treatment system. The maximum reduction of biological oxygen demand (BOD 5 ) from four types of greywater ranged from 85.3 to 98%, while was between 71.22 and 85.47% for chemical oxygen demand (COD) after 21 days. The reduction of nitrate (NO 3 -) appeared rapidly within 18 days of the treatment period with 98% of the reduction efficiency. Reduction of ammonia (NH 3 ) and orthophosphate (PO4 3-) was recorded after 21 days with the efficiency ranged from 86.21 to 99 and 39.12 to 99.3%, respectively. The high removal percentage of potassium (K) (97%) recorded within 3 days, while calcium (Ca) reduction (95%) was noted at the end of the treatment period indicating the high applicability of phycoremediation system to be used in the village houses. Moreover, the system is easily implementable, very low cost where no energy is required, eco-friendly and has no toxic by-products.

“…The recovering Ni 2+ ions from aqueous solution by the bacterial cells as a response for different concentrations of metal ions and cell biomass depend on the equilibrium between the metal ions and active sites available on the bacterial cell surface [2,10]. At low concentrations of Ni 2+ ions more active site are available for biosorption of metal ions, while at high concentrations of metal ions the free active sites become saturated with the metal ions with high concentrations of the metals still available in the solution.…”
