Abstract
In present article polycyclic aromatic hydrocarbons (PAHs) are analyzed due to their persistent as pollutants in marine ecosystem. These hydrocarbons may be responsible for long-term adverse effect to the mangrove ecosystem. Polycyclic aromatic hydrocarbons in mangrove sediments are analyzed using chemical and environmental magnetic methodology. Concentration, depth of contamination and sources of 16 PAHs observed in Airoli, Navi Mumbai mangrove sediments are investigated. Ten sediment samples from different depths were analyzed and presence of 16 polynuclear aromatic hydrocarbons (PAHs) is detected via gas chromatography/mass spectrometry. Sixteen PAHs i.e. Naphthalene (NAP), Acenapthalene (ACY), Acenaphthene (ACN), Fluorine (FL), Phenanthrene (PHT), Anthracene (ANT), Fluoranthene (FLA), Pyrene (PYR), Benz (a) Anthracene (BaA), Chrysene (CHR), Benzo (k) Fluoranthene (BkF), Benz (e) Acephenanthrylene (BeA), Ideno (1, 2, 3, -cd) Pyrene (INP), Dibenz (a, h) Anthracene (DBA), Benzo (a) Pyrene (BAP) and Benzo (ghi) Perylene are identified in most of the samples. Environmental magnetic parameters magnetic susceptibility (χ), anhysteretic remanent magnetization, Saturation Isothermal Remanent Magnetization and useful ratios of some required parameters are used to ascertain grain size of the magnetic mineral assemblage. Present article is an attempt to discuss importance of integrated study that the mineral magnetic measurements along with chemical analyses may be of great value to understand environmental conditions that prevailed in the mangrove sediments.
