Can Geochemical Baseline be used to determine heavy metal enrichment?
The contents of Cr, Ni, and Cd were within the background level. Geochemical baseline can be used not only to determine the enrichment degree but also as a potentially useful tool for identifying the pollution source (local and non-point source) of heavy metals in sediments.
How to determine pollution source of heavy metals in sediments based on Geochemical Baseline?
This study aims to determine the pollution source of heavy metals in sediments based on the geochemical baseline by using statistical methods. The geochemical baseline values of surface and core sediments in Lihu Lake, a typical urban lake in Taihu Lake Basin, were calculated by relative cumulative frequency and iterative methods.
What are the sources of heavy metal pollution?
According to Ross (1994), the anthropogenic sources of metal contamination can be divided to five main groups:
Metalliferous mining and smelting (As, Cd, Pb, Hg)Industry (As, Cd, Cr, Co, Cu, Hg, Ni, Zn)Atmospheric deposition (As, Cd, Cr, Cu, Pb, Hg, U)Agriculture (As, Cd, Cu, Pb, Si, U, Zn)What is metal pollution?
Heavy metals normally occur in nature and are essential to life but can become toxic through accumulation in organisms.
Arsenic, cadmium, chromium, copper, nickel, lead and mercury are the most common heavy metals which can pollute the environment.What is the difference between Geochemical Baseline and background concentration?
The difference between geochemical baseline and background concentration for a specific metal in sediment is that: a background is the natural concentration of the metal, and a baseline is the determined concentration at specific time and thus includes natural and human influences.
What is the main metallic water pollutant?
The most common heavy metal pollutants are arsenic, cadmium, chromium, copper, nickel, lead and mercury.
There are different types of sources of pollutants: point sources (localized pollution), where pollutants come from single, identifiable sources.Where is heavy metal pollution found?
Baseline and premining geochemical characterization of mined sites Heavy metal pollution and spatial distribution in surface sediments of Mustafakemalpas¸ a stream located in the world's largest borate basin (Turkey) Background values for evaluation of heavy metal contamination in sediments in the Parnaiba River Delta estuary, NE/Brazil
Heavy metals emanate from geogenic (natural) and anthropogenic (man-made) sources.
These chemical species can pose severe ecological pollution and environmental degradation due to their high toxicity and non-bio-degradable nature.
