“…2014Cheng et al, 2015). They can evaporate entirely or partially during the high temperature of fuel combustion and can subsequently enter ambient air through exhaust gases generated after removal by various APCDs (Liu et al, 2002;Feng et al, 2003;Zhu et al, 2016). The combustion of fossil fuel, particularly coal, is believed to be the primary source of hazardous trace elements in the atmosphere and terrestrial and aquatic environments (Sakata et al, 2008;Basile et al, 2009;Nguyen et al, 2010).…”

In this study, a unit-based approach was used to establish an integrated emission inventory of primary PM 2.5 from fossil fuel (coal, oil, and natural gas) power plants in China. The inventory was of high spatial and temporal resolution, and composed of detailed chemical speciation. In 2014, the total emissions were estimated to be approximately 669.53 kt. The emissions of primary PM 2.5 from coal-fired power plants (CFPs) were 668.56 kt, making CFPs the largest contributor. The emissions of primary PM 2.5 from oil-fired power plants (OFPs) and natural gas-fired power plants (GFPs) were approximately 17.41 t and 945.60 t, respectively. Spatial distribution features demonstrated that the emissions in the eastern and central provinces of China were much higher than those in the west, except for provinces involved in the "west-to-east power transmission" project. For CFPs, crustal elements and water-soluble inorganic ions were the primary species of PM 2.5 . By contrast, for OFPs and GFPs, carbonaceous components were the predominant species of PM 2.5 . Moreover, this study conducted a scenario analysis of changes in PM 2.5 emissions resulting from technical advancement, penetration, and substitution of CFPs by GFPs for the target years.

“…The data published by the International Energy 34 Agency stated that the energy consumption had increased by 50.52% from 1990 to 2014. 35 Consequently, the appearance of environmental problems poses a serious threat to the living 36 environment of human beings, such as heavy metal pollution caused by municipal solid waste 37 incineration (MSWI) fly ash [1,2], global warming due to carbon dioxide (CO2) emissions [3], 38 and so forth. 39 40 Municipal solid waste (MSW) has been always one of the most challenging problems in the 41 management of modern cities.…”

13This paper presents both experimental and multi-physics studies on the carbonation and heavy 14 metal retention properties of cement-solidified fly ashes. Cement-solidified fly ash samples 15 with 40% and 60% fly ash ratios were tested for carbonation depth after being supercritically 16 carbonated. Tests were also carried out for compressive strength and retention capacity of heavy 17 metals of the samples before and after supercritical carbonation. Using CO2 absorption instead 18 of calcium carbonate to measure carbonation degree, a multi-physics model was developed and 19 combined with a leaching model to study the impact of carbonation on Cu and Pb leaching from 20 the cement-solidified fly ash. The results show that supercritical carbonation has both positive 21 and negative impacts on the strength and retention capability of heavy metals of the cement-22 solidified fly ashes, which suggests that both the carbonation conditions and the amount of fly 23 ash recycled in cementitious materials should be properly controlled to maximize potential 24 positive effect. 25 26 27

“…Removal of heavy metals from the wastewater is difficult because they exist in different chemical forms. Most metals are not biodegradable, and they can easily pass through different trophic levels to persistently accumulate in the biota [15,16].Removal of toxic pollutants is extremely important to minize the threat to human health and the surrounding environment. Removal of heavy metals achieved through various techniques such as reverse osmosis [17], ion exchange [18], chemical precipitation [19], adsorption and solvent extraction [20] include enormous operational and maintenance costs and are usually not environmentally friendly [19][20][21][22].…”

Application of Floating Aquatic Plants in Phytoremediation of Heavy Metals Polluted Water: A Review

et al. 2020

View full text Add to dashboard Cite

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.
