TL;DR: Collectively, biofilm development intensifies the role of MPs in the migration and fate of trace metals in freshwater, since it does not give MPs an edge over natural substrates in adsorption.

TL;DR: A series of laboratory and field studies were conducted to test suitability and optimal sampling conditions of an Amicon ultrafiltration system for the collection of colloidal material for trace metal phase speciation studies in marine environments as discussed by the authors.

TL;DR: Clams showed a complex pattern due to the variability introduced by size-related factors and the natural dynamics of SPM in the estuary, while Cr and Mn showed an apparent reverse industrial trend with higher concentrations in clams collected at distant stations near the turbidity maximum zone, possibly reflecting enhanced particle retention.

TL;DR: In this article, a dilute sulfuric acid solution containing trace metals whose concentrations exhibit log normal distributions is collected as wetfall-only and primarily on an event basis at a site in the Tennessee Valley.

TL;DR: The geoaccumulation index (I geo), calculated to estimate the enrichment of metal concentrations in soil, showed that the level of metal pollution in most surveyed areas is significant, especially for Pb and Cd; it is thus important to keep systematic and continuous monitoring of heavy metals and their derivatives to manage and suppress such pollution.
Abstract: There is a growing public concern over the potential accumulation of heavy metals in soil, owing to rapid industrial development. In an effort to describe the status of the pollutions of soil by industrial activities, relevant data sets reported by many studies were surveyed and reviewed. The results of our analysis indicate that soils were polluted most significantly by metals such as lead, zinc, copper, and cadmium. If the dominant species are evaluated by the highest mean concentration observed for different industry types, the results were grouped into Pb, Zn, Ni, Cu, Fe, and As in smelting and metal production industries, Mn and Cd in the textile industry, and Cr in the leather industry. In most cases, metal levels in the studied areas were found to exceed the common regulation guideline levels enforced by many countries. The geoaccumulation index (Igeo), calculated to estimate the enrichment of metal concentrations in soil, showed that the level of metal pollution in most surveyed areas is significant, especially for Pb and Cd. It is thus important to keep systematic and continuous monitoring of heavy metals and their derivatives to manage and suppress such pollution.
