“…However, the amounts of Cd, Cu, Ni, and Zn in both seasons were lower than the permissible value of the regulations [31,32]. Cd and Zn in the groundwater were not detected, perhaps because of the low content of Cd and Zn in the MSW [36], which might be reduced by plant absorption [37].…”

The municipal solid waste (MSW) landfill in Vientiane, Laos, which receives > 300 tons of waste daily, of which approximately 50% is organic matter, has caused serious environmental problems. This study was conducted to investigate the accumulated levels of heavy metals (HMs) (cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn)) in water (surface and groundwater), soil, and plants between dry and wet seasons according to the standards of the Agreement on the National Environmental Standards of Laos (ANESs), Dutch Pollutant Standards (DPSs), and the World Health Organization (WHO), respectively. Although no impact of pollution on the surface water was observed, the levels of Cr and Pb in the groundwater significantly exceeded the basics of ANESs and WHO in both seasons. The pollution caused by Cd and Cu reached the eco-toxicological risk level in the landfill soils and its vicinity. The vegetable Ipomoea aquatica, which is consumed by the nearby villagers, was seriously contaminated by Cr, Pb, Cu, and Zn, as the accumulation of these toxic metals was elevated to much greater levels as compared to the WHO standards. For the grass Pennisetum purpureum (elephant grass), the quantities of HMs in all plant parts were extreme, perhaps due to the deeper growth of its rhizome than I. aquatica. This study is the first to warn of serious HM pollution occurring in the water, soil, and plants in the MSW landfill of Vientiane, Laos, which requires urgent phytoremediation. The indication of what sources from the MSW principally cause the pollution of HMs is needed to help reduce the toxicological risks on Lao residents and the environment in Vientiane as well.

“…The chemical composition of heavy metals, plant age, physiology of absorption and excretion of elements from the body of organisms, physical and chemical factors and the function of heavy elements in various organs of aquatic organisms can have a significant impact on the absorption of heavy metals by aquatic plants (Almeida et al 2011). Many studies have been conducted to determine the accumulation of heavy metals in aquatic plants (Axtell et al 2003;Bonanno and Giudice 2009;Engi et al 2015). For instance, earlier report (Favas and Pratas 2013) showed the importance of absorption of heavy metals by some aquatic plants such as Ranunculus trichophyllus, Azolla caroliniana and Juncusus.…”

Uptake and accumulation of heavy metals by water body and Azolla filiculoides in the Anzali wetland

The Anzali international wetland is a valuable habitat to a wide variety of aquatic flora and fauna. This wetland ecosystem is being threatened due to various pollutants particularly the heavy metals discharging from different point and non-point sources. Concentration of various heavy metals (Cr, Pb, Hg, Cu, Zn, Cd, Ag and Ti) was examined in the water body and Azolla filiculoides (an exotic fern in the Anzali wetland). The samples regarding water and A. filiculoides were randomly carried out in three parts of the wetland (eastern, central and western parts) in May 2015. After preparing and digesting the samples, the concentration of the heavy metals was measured using ICP OES method. The obtained results showed that the concentration of Zn in water and A. filiculoides samples was higher than other heavy meals in all parts of the wetland (p < 0.05). Overall, concentration of the heavy metals was significantly higher in the eastern part of the wetland than other two sampling locations (p < 0.05). Also with comparing the concentration of the heavy metals in water and A. filiculoides, it was found that all examined metals (except Cd and Ag) in A. filiculoides had significantly higher concentration than water sample, while Cd and Ag in water and A. filiculoides did not have a significant difference with each other. Based on the results, it can be concluded that A. filiculoides can effectively absorb Cr, Pb, Zn, Hg, Cu, Cd, Ag and Ti so that it might be used as a valuable species for the bioremediation and the removal of heavy metals from the wetland.

“…Iron is an essential element for plants (Wintz et al ., 2002) and plays a vital role in enzymatic processes such as chlorophyll and protein biosynthesis as well as in cellular respiration. On the contrary, excessive accumulation of this element damages tissues through free radicals production (Bienfait, 1988; Engin et al ., 2015). Markert (1992) proposed 5–200 mg kg −1 as phytotoxic concentrations for Fe; this range was exceeded in the sampled aquatic plants.…”

A preliminary environmental assessment of four heavy metals (Mn, Pb, Zn and Fe) on the coast of Campeche, Mexico was carried out. Surface sediments (0–10 cm), water and plants were collected in four sites of the coastline to obtain information about the levels and spatial distribution of the selected elements. The bioconcentration factor (BCF) was calculated for plants, where the BCF of Mn (3.375–3.558) and Zn (0.291–0.888) were high for Conocarpus erectus (button mangrove) and the BCF of Fe ranged from 0.022 to 0.023 in Laguncularia racemosa (white mangrove). This study showed that a significant source of metal contamination in the coastline of Campeche could be the discharge of municipal sewage. The relationship among metals, water, sediments and plants revealed a distinct behaviour of metals transportation in the marine environment. Mangroves operated as excluder species for nonessential metals (Pb) and accumulators for essential metals (Zn). Results showed that mangroves could be employed as a phytostabiliser of heavy metals.
