Journal ArticleDOI
TL;DR: In this article, the authors investigated the effect of industrial wastewater discharge on the global geochemical system due to wastewater discharge and found that the amount of metals in municipal wastewater by man is now of the same order of magnitude as the injection of the metals by natural weathering.

TL;DR: The trace metal concentrations in alpine mosses can be regarded as a reliable estimate of total atmospheric deposition, i.e., including occult deposition by cloudwater, in close relation to cloud cover frequency.

TL;DR: In this article, the concentrations of trace metals and elements in the coarse fraction of atmospheric particulate matter (CPM, particles smaller than 10 and larger than 2.5 μm in diameter, PM10-2.5) and their spatial and temporal trends were investigated in the greater Los Angeles area.
Abstract: The concentrations of trace metals and elements in the coarse fraction of atmospheric particulate matter (CPM, particles smaller than 10 and larger than 2.5 μm in diameter, PM10–2.5) and their spatial and temporal trends were investigated in the greater Los Angeles area. Ten distinct sampling sites were chosen to encompass a variety of CPM sources, including urban, rural, coastal, inland, and near-freeway sites. Time-integrated 24-h CPM samples were collected at each location once a week, for an entire year, from April 2008 to March 2009, to characterize drivers of the seasonal and spatial patterns of the CPM trace metal content. Metals were quantified using sector-field inductively coupled plasma mass spectrometry (SF-ICP-MS). Trace metals in CPM displayed distinct seasonal and temporal variations, and a principal component analysis (PCA) was performed to aid the identification of the CPM sources underlying these variations. The probable sources of each principal component were identified using elemental...

TL;DR: The correlation between various physiochemical variables and trace metals suggested significant role of fine grained particles (clay) in trace metals distribution whereas owing to low organic carbon content in the region the organic complexation may not be playing significant role in trace metal distribution in the Sundarban mangroves.
Abstract: The distribution, enrichment, and ecotoxicity potential of Bangladesh part of Sundarban mangrove was investigated for eight trace metals (As, Cd, Cr, Cu, Fe, Mn, Pb, and Zn) using sediment quality assessment indices. The average concentration of trace metals in the sediments exceeded the crustal abundance suggesting sources other than natural in origin. Additionally, the trace metals profile may be a reflection of socio-economic development in the vicinity of Sundarban which further attributes trace metals abundance to the anthropogenic inputs. A total of eleven surficial sediment samples were collected along a vertical transect along the freshwater-saline water gradient. The sediment samples were digested using EPA 3051 method and were analyzed on ICP-MS. Geo-accumulation index suggests moderately polluted sediment quality with respect to Ni and As and background concentrations for Al, Fe, Mn, Cu, Zn, Pb, Co, As, and Cd. Contamination factor analysis suggested low contamination by Zn, Cr, Co, and Cd, moderate by Fe, Mn, Cu, and Pb while Ni and As show considerable and high contamination, respectively. Enrichment factors for Ni, Pb, and As suggests high contamination from either biota or anthropogenic inputs besides natural enrichment. As per the three sediment quality guidelines, Fe, Mn, Cu, Ni, Co, and As would be more of a concern with respect to ecotoxicological risk in the Sundarban mangroves. The correlation between various physiochemical variables and trace metals suggested significant role of fine grained particles (clay) in trace metal distribution whereas owing to low organic carbon content in the region the organic complexation may not be playing significant role in trace metal distribution in the Sundarban mangroves.
