The objectives of this study are to use different types of indexes to assess the current pollution status in Mengkabong lagoon and select the best index to describe the Mengkabong sediment quality. The indexes used in this study were Enrichment Factor (EF), Geo-accumulation Index (Igeo), Pollution Load Index (PLI) and Marine Sediment Pollution Index (MSPI). Different indexes give diverse status...

Heavy metal contamination due to natural and anthropogenic sources is a global environmental concern. Release of heavy metal without proper treatment poses a significant threat to public health because of its persistence, biomagnification and accumulation in food chain. Non-biodegradability and sludge production are the two major constraints of metal treatment. Microbial metal bioremediation is...

Introduction: CM chondrites contain minerals that formed by interaction between liquid water and anhydrous minerals [1]. How this process progressed on the parent body is important for understanding how to unravel the effects of aqueous alteration in these meteorites. Studies undertaken to qualify [1] and quantify [2] the extent of alteration found in the CMs resulted in a mineralogic alteratio...

Background & Aims of the Study: The objective of this study was to investigate the seed pre-treatment with salicylic acid (SA) on tolerance and remediation ability of Brassica oleracea var. acephala under lead and zinc stresses. Materials and Methods: Present study was conducted to evaluate phyto-accumulative ability of Brassica oleracea var. acephala in heavy metal concentrat...

 In a complementary field study, the concentrations of some metals (Cu, Ag, Pb, Zn, Ni, Co, Mn, Fe, As, Cd, Cr, Mg and Ba) were measured in clam Solen dactylus, sediments and water collected at two stations (Park-e-Qadir, 56° 20/ E, 27° 11/ and Nakhl-e-Nakhoda, 56° 23/ E, 27° 10/ N) of Bandar Abbas coastal waters of the Persian Gulf in November 2008 and February 2009 showing different contamina...
