Determination of trace metal(loid)s in mangrove swamp sediments in relation to its adjacent host rocks of South Andaman, India

Ten representative fresh rock samples distributed sparsely were collected in each station’s viz., Rutland Island (RT), Chidyatapu (CT), Burmanallah (BN), Carbyn’s cove (CC), Redskin Island (RS), Wandoor (WD), Guptapara (GP), Manjery (MJ), Shipighat (SG), and Junglighat (JG) in South Andaman island f...

Description
Summary:Ten representative fresh rock samples distributed sparsely were collected in each station’s viz., Rutland Island (RT), Chidyatapu (CT), Burmanallah (BN), Carbyn’s cove (CC), Redskin Island (RS), Wandoor (WD), Guptapara (GP), Manjery (MJ), Shipighat (SG), and Junglighat (JG) in South Andaman island for identifying the background values of the trace metal(loid)s viz., V, Cr, Co, Ni, Cu, Zn, Zr, Pb, As, and Fe. Correspondingly, quadruplet samples of mangrove sediments from those ten stations were studied for the aforementioned trace metal(loid)s. Incidence of trace metal(loid)s in rock and mangrove sediments were assessed using wavelength dispersive X-ray fluorescence (WD-XRF) spectrometry. Geo-chemical indices such as enrichment factor (EF), contamination factor (CF), geo-accumulation index (Igeo), and anthropogenic factor (AF) were used to gauge the levels of trace metal(loid)s in mangrove sediments. The results suggest that the incidence of various trace metal(loid)s in the mangrove sediments are from the adjacent host rock (AHR) in all the stations except station JG. The computed values EF, CF, Igeo, and AF articulate that station JG exhibits minor enrichment, considerable contamination, moderately polluted, and anthropogenic influence respectively.
