“…L. minor met the basic characteristics of metal hyperaccumulation and was found to be a hyperaccumulator of both Ni and Cr in all experimental concentrations. Obek () determined L. gibba L.'s heavy metal accumulating capability in secondary treatment effluence and found it to have high ability to remove Cr in secondary treatment effluence as well: 300% on the first day, 360% on the second day and 500% on the fifth day of experimental period.…”

“…Therefore, L. minor might be useful in the treatment of water contaminated with Ni and Cr, individually. Obek () determined Ni accumulation using L. gibba L. in secondary treatment effluents, but observed no significant changes in Ni accumulation levels during the seven day experimental period. According to results by Appenroth et al .…”

This study investigated the use of Lemna gibba and Lemna minor plant species to absorb Cr, Ni and Co from Alacakaya mining area water. Lemna gibba and L. minor were separately placed to feed into two reactors. Water and plant samples were collected for eight consecutive days, and the pH, electric conductivity and temperature of the water were measured. The plants were washed, dried and burned at 300°C for 24 h in a drying oven. The samples were then analysed by ICP‐MS (inductively coupled plasma mass spectroscopy) for concentrations of Cr, Ni and Co, which were 1.2, 0.9 and 0.5 μg L−1 respectively. On Day 8, the determined uptake of L. gibba and L. minor were: 196 and 398% for Cr; 307 and 1473% for Ni; and 166 and 223% for Co respectively. Lemna gibba and L. minor were thus effective in absorbing Cr, Ni and Co from mining water.

“…Aquatic phytoremediation with floating aquatic plants for nutrient removal has a large potential, especially in tropical and subtropical regions of the world (Olguín et al, 2008). Among these species may be cited: Azolla caroliniana Willd, Salvinia minima Baker and Lemna gibba Linnaeus (Mkandawire & Dudel, 2005;Olguín et al, 2008;Hayes, 2010;Obek & Sasmaz, 2011).…”

Potential of macrophytes for removing atrazine from aqueous solution

et al. 2011

-The potential of three macrophytes, Azolla caroliniana, Salvinia minima, and Lemna gibba was assessed in this study to select plants for use in environmental remediation contaminated with atrazine. Experiments were carried out in a greenhouse over six days in pots containing Hoagland 0.25 strength nutritive solution at the following atrazine concentrations: 0; 0.01; 0.1; 1.0; 10.0 mg L -1 . Decrease in biomass accumulation was observed in the three macrophytes, as well as toxic effects evidenced by the symptomatology developed by the plants which caused their deaths. The chlorosis and necrosis allowed to observe in the plants the high sensitivity of the three species to the herbicide. Plants presented low potential for removal of atrazine in solution when exposed to low concentrations of the herbicide. However, at the 10.0 mg L -1 atrazine concentration, L. gibba and A. caroliniana showed potential to remove the herbicide from the solution (0.016 and 0.018 mg atrazine per fresh mass gram, respectively). This fact likely resulted from the processes of atrazine adsorption by the dead material. The percentage of atrazine removed from the solution by the plants decreased when the plants were exposed to high concentrations of the pollutant. Azolla caroliniana, S. minima, and L. gibba were not effective in removing the herbicide from solution. The use of these species to remedy aquatic environments was shown to be limited.Keywords: Azolla caroliniana, Salvinia minima, Lemna gibba, herbicide, bioremediation.RESUMO -Avaliou-se, neste estudo, o potencial de três macrófitas -Azolla caroliniana, Salvinia minima e Lemna gibba -com vistas à seleção de plantas para remediação de ambientes contaminados por atrazine. Foram realizados experimentos em casa de vegetação durante seis dias, em vasos contendo solução nutritiva Hoagland (0,25 de força iônica), nas seguintes concentrações de atrazine: 0; 0,01; 0,1; 1,0; e 10,0 mg L -1 . A redução da biomassa acumulada pelas macrófitas foi observada, bem como os efeitos de toxidez evidenciados pela sintomatologia desenvolvida nas plantas, os quais causaram sua morte. Clorose e necrose observadas nas plantas mostraram a alta sensibilidade das três espécies ao herbicida. As plantas demonstraram baixo potencial para remoção de atrazine, quando expostas ao herbicida em baixas doses. Entretanto, na concentração de 10,0 mg L -1 de atrazine, L. gibba e A. caroliniana mostraram potencial para remover o herbicida da solução (0,016 e 0,018 mg de atrazine por grama de massa fresca, respectivamente). Esse fato provavelmente resultou do processo de adsorção de atrazine pela matéria morta. A porcentagem de atrazine removida da solução pelas plantas diminuiu quando estas foram expostas a altas concentrações do poluente. Azolla caroliniana, S. minima e L. gibba não foram eficazes na remoção do herbicida na solução. A utilização dessas espécies para sanar ambientes aquáticos mostrou-se limitada.

“…For example, increased incidences of cancer in some villages of this basin might result from water pollution (Yin 2005). Previous investigations have shown that the metals in the Shaying River pose a potential risk on ecosystem safety and public health, mainly because many of them, e.g., lead, cadmium and chromium, bio-accumulate in aquatic food chains (Obek 2009;Walkuska et al 2010). Even at low aqueous concentrations, the metals can damage the nervous system (Johnson and Atchison 2009) and disrupt the immune system (Mishra 2009).…”

Because of serious pollution of river water, people living along the Shaying River in China exploit the groundwater as a drinking water resource. Various pollutants including heavy metals have been detected in the groundwater at depths up to 200 m. To perform a non-carcinogenic risk assessment, the hazard index (HI) was determined for several metals present in the groundwater. High resolution inductively coupled plasma-mass spectrometry and inductively coupled plasma-atomic emission spectroscopy were used to measure the levels of Hg, Fe, Mn, Zn, Cd, Cr, Cu and Pb in source groundwater of eight tap water treatment plants (WTPs) during a 3-year period (2007-2009). Zn was present at the highest concentration of up to 101.2 μg l(-1) and Cd contributed the most (57.8%) to the HI in the WTPs, followed by Mn (14.3%) and Cr (13.1%). Both hazard quotients of individual metals and HI of total non-carcinogenic risk in each WTP were below 1.0, suggesting that the water posed negligible health risk on local residents. Temporal and spatial comparisons showed that high HIs tend to occur in low water periods (i.e., summer), and the City Pressure Station (Fuyang City) had the highest HI, followed by Yingnan Pressure Station (Yingnan Country) and Taihe WTP (Taihe Country). This study provides benchmark information useful for regulatory authorities to control the discharge of metals into the Shaying River Basin, and serves as a basis for comparison to other river systems in the world.
