  • Biosorption of strontium by Padina sp. algae biomass: process optimisation and equilibrium study

    Biosorption of strontium by Padina sp. algae from aqueous solutions was studied. A response surface methodology (RSM) was employed to optimise the biosorption parameters. The effects of pH, initial metal concentration in solution, biomass dosage and temperature on the strontium uptake by the algae were investigated. RSM analysis showed that the experimental data were adequately fitted to ...

  • Characterisation of a bioassay using the marine alga Dunaliella tertiolecta associated with spectroscopic (visible and infrared) detection

    This paper describes an ecotoxicological test using the alga Dunaliella tertiolecta associated with visible (VIS) and infrared (FTIR) spectroscopic detection. The estimation of toxicity is performed by measuring the cell density at 432 nm instead of 665 nm the results are comparable with those obtained by conventional visual or automatic estimation of celle density. FTIR spectroscopy gives an ...

  • Principal component analysis to assess the efficiency and mechanism for ultraviolet-C/polyaluminum chloride enhanced coagulation of algae-laden water

    Polyaluminum chloride (PAC) coagulation, short wavelength ultraviolet (UV-C at 254 nm) treatment and UV-C/PAC treatment of algae-laden water from Meiliang Gulf (Lake Taihu) were conducted. The intrinsic characteristics and correlations of chromophoric dissolved organic matter (CDOM), algae biomass and other contaminants were investigated. Parallel factor analysis determined four CDOM components, ...

  • Economic impact of algae blooms

    How much does an algae bloom cost? What is the price of inaction? Algae and cyanobacteria blooms are issues of considerable concern for environmental agencies, drinking water companies, municipalities and people alike. The incidence of Harmful Algae Blooms (HAB), along with its adverse effects, have been increasing in recent years as a result of climate change, increased fertilizer runoffs into ...

  • How listening to the ocean can help reveal environmental damage

    In 2013, Katherine Indeck listened to recordings of sounds made in a channel between the Gulf of Mexico and Tampa Bay, Florida. Some of the audio files had been collected in 2005 during an unusually severe red tide, a bloom of toxic algae that killed fish, dolphins and sea turtles. Other recordings were made after the ecosystem began to recover. During the recovery years, Indeck could hear sounds ...

  • Can harmful algal blooms be predicted?

    Summer 2015, as the eighth month of the year approaches (August), we are starting to hear and read in the news about sudden algal blooms occurring in freshwater lakes and marine environments. Many popular beach resorts have put up warning signs proclaiming the water is unsafe for recreational purposes. This is an understandable precautionary measure since phytoplankton abundance or more ...

  • Stocking up filtration equipment for marine expeditions

    February is here, and for many research teams across the world, that means it’s time to set sail. Shoulder seasons are an important time to conduct marine research because many algal and microbe species are in bloom. Whether your research has you voyaging the open sea or cruising in coastal waters, Sterlitech is here to stock the ship with all your laboratory filtration needs. We are proud ...
