“…In contrast, the concentration of lead in the current study was slightly higher than the values reported for gray water [29]. Deterioration of sewerage pipelines and the wear of household plumbing fixtures are considered important sources of Co in domestic wastewater [23,34]. Concentrations of Co, Cd, Fe, Mn and to some extent Cu in the present study were higher than the allowable limit for irrigation.…”

Water is becoming a scarce resource in terms of quantity and quality. Water supply enhancement measures are being taken with less attention given to wastewater management, leading to increased discharge of untreated wastewaters. Wastewater is emerging as an affordable and reliable alternative water supply for urban agriculture, supporting thousands of farmers. Extensive use of untreated wastewater for irrigation will without a doubt lead to accumulation of heavy metals in soils and crops, resulting in overwhelming risks to both public health and the environment. This paper deals with determination of the strength and compositions of the wastewater from a public university in the tropical semiarid region for rainy and dry seasons, based on a number of key parameters including heavy metals. Furthermore, it identified the real advantages of treated water use and issues pertaining to untreated wastewaters use for irrigation purposes. An independent t test showed significant differences in concentrations of all the tested metals, excluding lead, copper, and cadmium during dry and wet seasons. Similarly, differences were significant for electrical conductivity, biological oxygen demand, total nitrogen and total phosphorus. Salinity and concentrations of organics, nutrients, copper, cadmium, iron, manganese and to some extent copper exceeded the allowable thresholds for irrigation water. Lead, zinc, nickel and chromium, on the other hand, were lower than their respective limits. Wastewater used for irrigation purposes is unsafe, and urgent policy interventions on the use of untreated wastewater are required.

“…Similar results were obtained for E. Crassipes with 3 to 15 time more concentration in roots [13,18]. Due to industrial effluent, accumulation of various metal ions and external disturbance might affect the accumulation capacity of the plant [10,12,19].…”

Phytoremediation, an emerging technology which uses plants to remove contaminants of concern (COC) such as organic and inorganic compounds especially heavy metals (HM). The present study focuses on assessing the toxicity of heavy metals available in effluents discharged from industries and the accumulation ability of an aquatic plant, Eichhornia crassipes (water hyacinth). Phytoremedial potential of E. Crassipes and HM interaction between soil and water were evaluated in the present study under the presence of cow dung manure as an enhancer. Heterogenous accumulation of metal ions were found in the plant. Heavy metal concentration in plant parts were varied for roots and shoots. The concentration of HM ions in the plant parts were varied from root to shoot. Value of translocation factor (TF) was found to be in the region 0.5 â€“ 0.8, with Fe has low (0.51) and Pb has high (0.77), bioconcentration factor (BCF) were in the order of Ar > Ca > Zn > Fe > Pb at both roots and shoots. Transposition factor (TrF) of all HM ions were >1.5 except for Zn (1.21). E. Crassipes was found to accumulate a large amount of HM ions and could be used for efficient treatment of contaminated water.

“…Phytoremediation of heavy metals with aquatic plants has gained significant consideration due to its elegance and cost-effectiveness [39,227]. The earlier worker has demonstrated that aquatic plants have the capability to eliminate HMs from different kinds of wastewater [140,225,245,246].…”

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.
