Wastewater Irrigation-Sourced Plant Nutrition: Concerns and Prospects

Impacts of long-term irrigation with coalmine effluent contaminated water on trace metal contamination of topsoil and potato tubers in Dinajpur area, Bangladesh

“…Plants can uptake ionic elements from the soil solution because of the concentration gradient [ 97 ]. Therefore, excess trace metals could accumulate inside plants if they are available in soil in higher quantities [ 38 , 54 , 92 ]. In the present study we observed similar results, where trace metal contents in potato tubers harvested from wastewater irrigated site-III showed substantially higher trace metals compared to potato tubers harvested from groundwater irrigated site-I as well as surface water irrigated site-II ( Table 4 ).…”

“…In the present study we observed similar results, where trace metal contents in potato tubers harvested from wastewater irrigated site-III showed substantially higher trace metals compared to potato tubers harvested from groundwater irrigated site-I as well as surface water irrigated site-II ( Table 4 ). The only possible explanation could be higher trace metal availability in site-III soil leading to higher uptake and accumulation in potato tubers [ 38 , 54 , 97 ]. Numerous previous studies investigating the trace metals accumulation in different plants as a result of wastewater irrigation also concluded the same way that, wastewater carried a substantial amount of trace metals that in turn increased soil trace metal levels and ultimately elevated trace metal accumulation in plant parts [ 5 , 10 , 21 , 57 , 58 , 96 ].…”

“…However, recent studies outlined that potato is very prone to trace metal accumulation as it remains directly in contact with soil [ 51 , 52 ]. Metals and metalloids are naturally available in the soil system, but careless human activities like unplanned effluent management and long-term irrigation with contaminated wastewaters are bound to fill up the trace metal bearing capacity of the soil, after which these trace elements find their way towards contaminating groundwater, surface water and eventually the plants and crops [ 53 , 54 ]. As the most popular vegetable, high trace metal accumulation in potatoes would pose a greater health risk because food chain contamination is one of the major routes for trace metals' entry into the human body [ 23 , 33 , 55 ].…”

Remediation of wastewater by biosynthesized manganese oxide nanoparticles and its effects on development of wheat seedlings

“…Wastewater disturbs the physical and physicochemical system of wheat due to the high concentration of COD, TDS, and nutrients ( Zhang et al., 2021 ). The high amounts of phosphate and nitrate disturb metabolism by unbalancing the nutritional system of plants and accumulating in cells and tissues ( Ahmad et al., 2020 ). The chlorophyll parameters of wheat decreased considerably under wastewater treatment as compared to treated wastewater ( Figure 8 ).…”

Removal of Potentially Toxic Elements (PTEs) from Contaminated Water Using Microcrystalline Cellulose Extracted from Rice Straw

“…The agricultural sector consumed 62.4 B m 3 , while the drinking and healthy uses consumed 10.4 B m 3 .Wastewater recycling provided 1.3 B m 3 . As reviewed by Ahmad et al(2020) and Asano et al(2018), wastewater can be categorized into two categories based upon its derivation: domestic and industrial wastewaters. Industrial liquid wastes being drained which generate industrial wastewater having various components like FOG (fat, oil and grease), pharmaceutical wastes, chemicals, and other hazardous materials.…”
