“…The heavy metal emanating from effluents of various industries (such as tanneries, dye producers, textile dyeing plants, metal engineering, electroplating) may lead to the problem of heavy metal bioaccumulation in aquatic plants (Kara 2005) and fish (Hollis et al 2001;Long and Wang 2005;Marcussen et al 2007). It has been reported that heavy metals can accumulate in different tissues of freshwater fishes (Amundsen et al 1997;Ruangsomboon and Wongrat 2006) and marine fishes (Kalay et al 1999;Wong et al 2001).…”

“…Aquatic plants possess an immense potential to remove heavy metals from wastewater (Dushenkov et al, 1995;Kara, 2005). Though extensive literature is available highlighting the potential of several Salvinia species for accumulation/removal of various heavy metals including Ni, Cu, As, Pb, Cr, Zn from wastewaters (Sen and Mondal, 1990;Sen and Bhattacharya, 1994;Nigam et al, 1998;Nichols et al, 2000;Hoffman et al, 2004;Hadad et al, 2007), the physiological factors and regulatory mechanisms related to the greater potential of plants for tolerating high levels of heavy metals are not known.…”

Investigations were carried out to evaluate alterations in photosynthetic performance of Salvinia natans (L.) exposed to chromium (Cr) and zinc (Zn) rich wastewater. Accumulation of high levels of Cr and Zn in plants affected photosynthetic electron transport. Photosystem-(PS) II-mediated electron transport was enhanced in plants exposed to Cr rich wastewater while a decline was observed in Zn-exposed plants. Photosystem-I-mediated electron transport increased in plants exposed to Cr and Zn rich wastewater. Efficiency of photosystem II (F v /F m ) measured by fluorescence did not show any significant change in Cr-exposed plants but a decrease was observed in Zn-exposed plants as compared to the control. The enhancement in PS I-induced cyclic electron transport in Cr and Zn exposed plants led to a build up of the transthylakoidal proton gradient (∆pH) which subsequently helped in maintaining the photophosphorylation potential to meet the additional requirement of ATP under stress. The carbon assimilation potential was adversely affected as evident from the decrease in Rubisco (EC 4.1.1.39) activity. The alterations in photosynthetic electron transport affected stromal redox status and induced variations in the level of stromal components such as pyridine nucleotides in plants exposed to Cr and Zn rich wastewater. The present investigations revealed that alteration in the photosynthetic efficiency of Salvinia exposed to Cr could primarily be the result of a decline in carbon assimilation efficiency relative to light-mediated photosynthetic electron transport, though in the case of Zn-exposed plants both these factors were affected equally. Key words: carbon assimilation, electron transport, heavy metals, photophosphorylation, redox status Desempenho fotossintético de plantas de Salvinia natans expostas a água de esgoto rica em cromo e zinco: Avaliou-se o desempenho fotossintético de plantas de Salvinia natans L. expostas a água de esgoto rica em cromo (Cr) e zinco (Zn). O acúmulo de Cr e Zn em altos níveis afetou o transporte fotossintético de elétrons. O transporte de elétrons mediado pelo fotossistema (FS) II aumentou nas plantas expostas ao esgoto rico em Cr, observando-se o oposto nas plantas expostas ao esgoto rico em Zn. O transporte de elétrons mediado pelo FS I aumentou nas plantas expostas ao esgoto rico tanto em Cr como em Zn. A eficiência do FS II (F v /F m ) avaliada por fluorescência não variou significativamente em resposta ao Cr, porém reduziu-se nas plantas expostas ao esgoto rico em Zn, em comparação com as plantas-controle. O aumento do transporte cíclico de elétrons associado ao FS I acarretou em aumento do gradiente transtilacoidal de prótons (∆pH) que, por seu turno, esteve associado com o potencial de fotofosforilação para suportar as necessidades adicionais de ATP sob condições de estresse. O potencial de assimilação do carbono foi decrescido, conforme se deduz da menor atividade da Rubisco (EC 4.1.1.39). As alterações no transporte fotossintético de elétrons afetaram o status redox do estro...

“…The pH of the aqueous solution is an important operational parameter in the adsorption process because it affects the solubility of the metal ions, concentration of the counter ions on the functional groups of the adsorbent and the degree of ionization of the adsorbate during reaction (Kaonga et al 2010;Ghazy and Ragab 2007;Kara 2005;Onundi et al 2010). In order to find optimal pH value for the sorption process, the removal of copper ions in the pH range 2-6 was investigated and the data are illustrated in the Fig.…”

Heavy metal pollution of water is a serious problem because of its toxic effects on the human health and living organism. Therefore, there is a need to develop technologies to remove toxic pollutants found in polluted water. There are different ways to remove the toxic metals from wastewater. Among all treatments proposed, the adsorption process is one of the most promising technologies in water pollution control. Recently, numerous approaches have been studied for the development of cheaper and effective adsorbents. Many low-cost adsorbents, including natural materials, biosorbents and waste materials from industry and agriculture, have been proposed by several researchers. In this study, removal of copper from aqueous solution by using powdered and modified kernel of date (Fructus dactylus) with apocarbonic anhydrase enzyme has been investigated. The operating variables studied were contact time, initial solution pH, initial metal concentration, temperature and adsorbent dosage. The experimental investigation results showed that modified and powdered kernel of date (F. dactylus) has a high level of adsorption capacity for copper ions. The adsorption data were correlated with the Langmuir and Freundlich isotherm models. It was found that the Langmuir and Freundlich isotherms fitted well to the data. The results revealed that copper is considerably adsorbed on modified and powdered kernel of date (F. dactylus). Consequently, it is concluded that the modified and powdered kernel of date (F. dactylus) can be successfully used for the removal of the copper ions from the aqueous solutions.
