摘要: The spatial distribution of different classes molecular markers in Tokyo Bay sediments, a semi-enclosed system surrounded by one the most urbanized areas world, has been investigated. In order to study environmental stability chemical sewage markers, their isomeric composition was determined river particulate matter, waste-water influent and surficial sediments. Among characterized, linear alkylbenzenes (LAB) trialkylamines (TAM) were useful for tracing transport contaminants from point-sources pollution, because assessing biodegradation processes during transport. Detection LAB as well TAM sediments outside Bay, more than 20 km riverine inflow 300 m water depth, clearly indicates long-range lateral land-based pollutants.
