Abstract

The term arsenolipids describes a class of arsenic species that are not water-, but lipid-soluble. So far, there are 4 subcategories known: Arsenohydrocarbons (AsHC), Arseno Fatty Acids (AsFA), Trimethylarsino Fatty Alcohols (TMAsFOH), and Arsenosugar Phospholipids (AsPL). They have been found mainly in the marine environment (algae, various fish), but recent studies show their accumulation in land-based organisms after ingestion as well. Due to the lack of pure compounds, their toxicological potential was unclear until the synthesis was published (Taleshi et al., 2014) which made cytotoxicological studies possible. These studies quickly showed, that they are able to exert a similar cytotoxicity as inorganic As (Meyer et al., 2014). A study on Globicephala melas (long-finned pilot whale) regarding accumulation and metabolism of these compounds is being conducted in order to be able to assess the threat arsenolipids pose to humans and the environment.
