    Amphimedon viridis marine sponge as metal bioindicator for Al, Ba, Cr, Fe and Mn.

    BACKGROUND: Bivalves, oysters, and mussels are accepted as biological indicators for marine pollutants. Heavy metals biomonitoring on the environment was this study objective using A. viridis compared with Perna perna (mollusk bivalve). The area studied included Ilha Pituã in Vila Velha – ES and Ilha do Boi and Camburi Garden Beach in Vitoria - ES. METHODS: The sample collection comprised seawater, mussel (P. perna) and sponge (A. viridis). Al, As, Ba, Cr, Cu, Fe, Pb, Mn, K, Ti and Zn were analyzed using ICP OES. RESULTS For metal studied Al, Ba, Cr, Fe and Mn presented greater accumulation in A. viridis than in P. perna. The metal concentrations detected in seawater, sponge, and mussel could be related using PCA with 79.26% total variance demonstrating that A. viridis bioaccumulated more metals than P. perna. CONCLUSION: Sponge metal accumulation reflected not only spatial metal variation but also seasonal changes.

    Mangifera indica L. as airborne metal biomonitor for regions of the state of Espírito Santo (Brazil).
    (2020) Castro, Leonardo Zago de; Silva, Thaís R. B. da; Ronchi, Silas Nascimento; Guimarães, Adriana A. T.; Nalini Júnior, Hermínio Arias; Ribeiro, Juliano Souza; Coutinho, Silvia Cruz Goes; Schmitt, Elisângela Flávia Pimentel; Endringer, Denise Coutinho
    Inorganic pollutants are continuously introduced into the atmosphere. Bioindicators present an alternative method of monitoring air quality. This work proposes to evaluate the Mangifera indica L. leaves as a biomonitor for air quality. Quantification of aluminum (Al), barium (Ba), calcium (Ca), chromium (Cr), copper (Cu), iron (Fe), potassium (K), manganese (Mn), magnesium (Mg), sodium (Na), nickel (Ni), sulfur (S), strontium (Sr), titanium (Ti), and zinc (Zn) were determined in leaves of M. indica using optical emission spectrometer inductively coupled plasma (ICP-OES). The correlogram analyses demonstrated a strong positive correlation between Al and Fe. Contamination of the soil by vehicles and agricultural chemicals, in synergy with the influence of the winds, may be considered as a source of contamination. Enrichment factor (EF) index was used to distinguish between natural and anthropogenic sources. Detection of Mn and Cu could be associated with anthropogenic influence, demonstrating M. indica as a feasible tool to biomonitor air quality.
