Effect of Detergents on the Growth of Two Aquatic Plants: Azolla pinnata and Hydrilla verticillata
نویسنده
چکیده
The effect of three chemical formulationstwo surfactants, Sodium Lauryl Sulfate (SLS) and Sodium Dodecyl Benzene Sulfonate (SDBS) and a builder Sodium Tripolyphosphate (STPP) on two aquatic plants – Azolla pinnata and Hydrilla verticillata was studied at various concentrations for a period of five months, from November to March. It was observed that while the detergents favoured the growth of plants at lower concentrations, they hampered their growth at higher concentrations. SDBS was found to be the most toxic to these plants and STPP the least, with SLS exhibiting intermediate levels of toxicity.

Phytoremediation, a plant based green technology, has received increasing attention after the discovery of hyperaccumulating plants which are able to accumulate, translocate, and concentrate high amount of certain toxic elements in their above-ground/harvestable parts. Phytoremediation includes several processes namely, phytoextraction, phytodegradation, rhizofiltration, phytostabilization and ...

INTRODUCTION: Hydrilla verticillata L.f. Royle (hydrilla; Hydrocharitaceae), an invasive submersed plant native to Southeast Asia and Australia, was first introduced into the US through the aquarium trade in Florida in the 1950s (Schmitz et al. 1991). Hydrilla impacts freshwater resources in the US by its aggressive, canopy-forming growth that degrades aquatic ecosystems, limits recreation, fou...

متن کاملRemoval of Aqueous Selenium by Four Aquatic Plants
Several aquatic species were examined as potential phytoremoval agents for selenium in aqueous solutions. Selenium was initially present in concentrations of 0-100 ppm Se (as sodium selenite) in 10% Hoagland’s medium, and aquatic plants were grown in the medium for one week. Four aquatic plants were studied: Cattail ( Typha domingensis ), duckweed ( Lemna obscura ), hydrilla ( Hydrilla verticil...

The potential of three submerged aquatic plant species (Cabomba piauhyensis, Egeria densa, and Hydrilla verticillata) to be used for As, Al, and Zn phytoremediation was tested. The plants were exposed for 14 days under hydroponic conditions to mine waste water effluents in order to assess the suitability of the aquatic plants to remediate elevated multi-metals concentrations in mine waste water...
