This study had as main objective to use Laguncularia racemosa as a bioindicator of the presence of metals in the mangrove of the Buranhém river’s estuary, in the city of Porto Seguro, southern Bahia, in May 2017. For this purpose, green and yellow leaves from this plant were collected at four points in the estuary. These samples underwent acid digestion (USEPA 3050‑B method) for further quantification of metals by ICP OES. The minimum and maximum values for the concentration of metals found were, respectively (mg kg‑1) Cr: 0,29 - 2,90; Mn: 7,92 ‑ 72,13; Fe: 74,07 ‑ 392,67; Ni: 0,25 ‑ 1,24; Cu: 0,18 ‑ 1,19; Zn: 6,62 ‑ 16,93; Sr: 47,09 ‑ 167,28; Cd: 0,06 ‑ 36,42; Ba: 3,20 ‑ 17,24; and Pb: 2,59 ‑ 145,90. The results indicate that Laguncularia racemosa is a bioindicator of metals with a relevant potential regarding the quality of mangrove ecosystems.Downloads
