Temporal trends and identification of the sources of volatile organic compounds in coastal seawater

Volatile Organic Compounds (VOCs) in the marine environment are produced by biogenic sources (marine macroalgae, phytoplankton, sediments, etc.) as well from anthropogenic sources. The temporal variation of such VOCs was studied together with their relationship to biological, meteorological and physico-chemical factors. Sixty four different VOCs were quantified including halogenated (<LoD to 906 ng L(-1)), non-methane hydrocarbons (NMHC) (<LoD to 1539 ng L(-1)), mono-aromatics (<LoD to 4232 ng L(-1)), oxygenated (<LoD to 1539 ng L(-1)) and sulfur containing compounds (
