“…The mycorrhizal fungi in the root zone form an association with the roots of plants, and have a beneficial role in phytoremediation [97]. This plant-fungi association enhance the availability of essential plant nutrients through their hyphal network, modify the root exudates, alter soil pH and stimulate the bioavailability of various heavy metals to associated plants [98,99].…”

“…Some of the free-floating aquatic plants are well recognized for their capability to eliminate the metals from the contaminated environment: water hyacinth (Eichhornia crassipes) [128], water ferns (Salvinia minima) [129], duckweeds (Lemna minor, Spirodelaintermedia), [130,131], water lettuce (Pistiastratoites), [132], water cress (Nasturtium officinale) [133]. The potential of these free floating aquatic plant for the elimination of heavy metals is comprehensively studied in different studies [99,134,135]. Active transport of heavy metals in free-floating aquatic plants occurs from the roots, from where metals are transferred to other parts of the plant body.…”

Heavy-metal (HM) pollution is considered a leading source of environmental contamination. Heavy-metal pollution in ground water poses a serious threat to human health and the aquatic ecosystem. Conventional treatment technologies to remove the pollutants from wastewater are usually costly, time-consuming, environmentally destructive, and mostly inefficient. Phytoremediation is a cost-effective green emerging technology with long-lasting applicability. The selection of plant species is the most significant aspect for successful phytoremediation. Aquatic plants hold steep efficiency for the removal of organic and inorganic pollutants. Water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and Duck weed (Lemna minor) along with some other aquatic plants are prominent metal accumulator plants for the remediation of heavy-metal polluted water. The phytoremediation potential of the aquatic plant can be further enhanced by the application of innovative approaches in phytoremediation. A summarizing review regarding the use of aquatic plants in phytoremediation is gathered in order to present the broad applicability of phytoremediation.

“…Phytoremediation has been identified as an emerging, lowcost and eco-sustainable solution for HM pollution prevention and control. It is the most suitable alternative to conventional physicochemical remediation technologies, which are highly expensive, technically more suited to small areas, create secondary pollution and deteriorate soil fertility and thus, adversely affects agro-ecosystem (Ali et al 2013;Chandra et al 2015;Mahar et al 2016;Muthusaravanan et al 2018).…”

“…According to the chemical composition of different parts of the date palm, it can be used for absorbing heavy metals such as lead. Lead is one of the toxic heavy metals that our environment accumulated of that heavily [67,68]. Most of the industries such as newsprints, battery industries, smelting, petrochemicals and so on release it and contaminate the environment [69].…”

Date palm (phoenix dactylifera), which is mostly found in the middle east countries such as Iran, Iraq, Saudi Arabia, and the United States (California) that play a significant role in the economical and the environmental condition in those areas. The main purpose of planting dates is its fruit, which is consumed as fresh, dried or processed forms. There are approximately 100 million date palm trees in the worldwide that 62 million of these trees located in the Middle East and North Africa. In Saudi Arabia only, 15000 tons of date palm leaves is prepared as waste materials. The leaves of date palm tree are used in several applications such as making ropes, baskets, and mats in many parts of the world. Unfortunately, the huge amount of the non-food products from the date palm remains as landfill materials without any specific usage. By attention to the date palm properties, the literature clearly showed that each part of date palm has great potential to be used for a variety of applications such as: making paper, absorption of heavy and toxic metals, energy production and soil fertilizing. Some of the obstacles and solutions for using palm date in these applications were also explored. Considering these issues and their solutions, the date palm is a favorable alternative. Despite some limited and traditional uses of these palm wastes, this review considered date palm applications and the properties' of the most important part of that tree in recent researches and related issues for future research are also spotted.
