“…The experimental plant S. polyrhiza, exhibited significant potentiality with respect to fluoride accumulation in concentration and duration-dependent manner. The results obtained are in agreement with the earlier findings on aquatic plants that have shown significant fluoride accumulation and its removal ability with increasing concentrations (Sinha et al 2000;Zhou et al 2012;Sharma and Kaur 2017). Bioaccumulation of toxic metals from polluted water by members of the duckweed family (L. minor and L. trisulca) is well documented (Samardakiewicz and Woźny 2000).…”

The present study was designed to assess the fluoride mediated antioxidant defence responses in Spirodela polyrhiza, grown under hydroponic conditions. The plants of S. polyrhiza were exposed to different fluoride concentrations (0, 5, 10, 15, 20, 25, 50 ppm) for the time period 24, 72, 120 and 168 h. Fluoride was observed to be readily accumulated by S. polyrhiza at all the exposure periods. Increased accumulation of fluoride triggered the oxidative stress that was quite evident from enhanced electrolyte leakage, proline, anthocyanin and phenolic content To counterbalance the stress, plant responded by the alterations in the activities of antioxidative enzymes (SOD, CAT, APOX, POD, GR), that was also supposed to confer tolerance ability to plant. Moreover, SEM-EDX, CLSM and FT-IR studies were also performed to confirm oxidative damage. Hence, it can be elucidated that this plant can act as an efficient fluoride accumulator and antioxidant defence system minimized fluoride toxicity. ARTICLE HISTORY

“…Water borne dental fluorosis and crippling skeletal fluorosis has been reported as a common diseases observed in India (Ayoob and Gupta 2006). Though fluoride contamination is primarily a ground water problem, fluoride laden effluent also emanates from various industrial establishments such as phosphate based fertilizer plants and factories producing aluminum, iron, glass, and ceramics etc (Zhou et al 2012). …”

Phytoremediation, popularly known as 'green technology' has been employed in the present investigation to examine the potential of fluoride removal from water by some aquatic plants. Fluoride contamination in drinking water is very much prevalent in different parts of the world including India. Batch studies were conducted using some aquatic plants e.g., Pistia stratiotes, Eichhornia crassipes, and Spirodela polyrhiza which profusely grow in natural water bodies. The experimental data exhibited that all the above three aquatic floating macrophytes could remove fluoride to some relative degree of efficiency corresponding to initial concentration of fluoride 3, 5, 10, 20 mg/l after 10 days exposure time. Result showed that at lower concentration level i.e., 3 mg/L removal efficiency of Pistia stratiotes (19.87%) and Spirodela polyrhiza (19.23%) was found to be better as compared to Eichhornia crassipes (12.71%). Some of the physiological stress induced parameters such as chlorophyll a, chlorophyll b, total chlorophyll, carotenoid, total protein, catalase, and peroxidase were also studied to explore relative damage within the cell. A marginal stress was imparted among all the plants for lower concentration values (3 mg/L), whereas at 20 mg/l, maximum damage was observed.

Diante da constatação cada vez maior de contaminação natural e antrópica por íons fluoreto (F-) em diversos aquíferos utilizados para abastecimento público, o presente trabalho tem por finalidade apresentar e analisar os principais tipos de tratamento (tradicionais e alternativos) disponíveis até o momento para sua remoção. Verificou-se que o método de adsorção é o mais aplicado, utilizando-se a alumina ativada como principal agente. No entanto, novos materiais vêm sendo estudados para substituir a alumina, de modo a diminuir os custos e aumentar a eficiência do tratamento. Os materiais alternativos que vêm sendo mais estudados ultimamente são os biocarvões (biochars), produzidos a partir da queima de diferentes tipos de biomassa, e as nanopartículas naturais e sintéticas. Além da adsorção, destacam-se outros métodos como os tratamentos químico e eletroquímico, o uso de membranas e a fitorremediação. A escolha do melhor método, no entanto, dependerá das características de cada técnica, além daquelas da própria água a ser tratada. Apesar dos custos e da eficiência do processo serem fundamentais nessa escolha, é preciso também levar em consideração a geração de resíduos no final de cada tratamento, como o próprio material adsorvente, lodos e efluentes líquidos concentrados em F-, que deverão ser corretamente destinados.
