However, alkylsulfides generated during the Grignard derivatization from elemental sulfur occurring in the sediment are not removed by this procedure. , 2000). Florisil is a preferred adsorbent for biotic matrix with a high lipid content. Hexane or hexane-Et2O mixtures are the most widely used eluents during the clean-up step because they allow GC determination without evaporation to dryness. More volatile solvent such as pentane is used to minimize the evaporation losses of the most volatile species.
Cadmium is also found in industrial paints and may represent a hazard when spray applied. Operations involving removal of cadmium paints by scraping or blasting may similarly pose a significant hazard. , 1998). 4. , 1995). These include the use of mono-methyl tins, mono-butyltins and di-butyltins as stabilizers in polyvinyl chloride (PVC) and as catalysts in industrial processes. , 1995), as previously mentioned. , 1997; Fatoki, 2000). 5. Pollution source – Points of heavy metals (HMs) Nonpoint sources of heavy metals pollution are mostly natural.
The soluble forms are generally ions or unionized organometallic chelates or complexes. , 1984). Heavy metals in surface water systems can be from natural or anthropogenic sources. Currently, anthropogenic inputs of metals exceed natural inputs. Excess metal levels in surface water may pose a health risk to humans and to the environment (Nriagu, 1996). Considering that heavy metals are natural constituents of the Earth's crust, they are present in varying concentrations in all ecosystems and human activities have drastically changedthe biogeochemical cycles and balance of some of these heavy metals.
