Steroids as Sewage Specific Indicators in New York Bight sediments
Bulletin of Environmental Contamination and Toxicology
|April 1, 1977
Summary
Researchers identified high levels of coprostanol and 24 beta-ethyl coprostanol in New York Bight sediments. These steroidal compounds originate from sewage and can serve as effective tracers for marine sediment pollution.
Area of Science:
- Environmental chemistry
- Marine geology
- Organic geochemistry
Background:
- Marine sediments can accumulate various organic compounds from anthropogenic sources.
- Steroidal compounds are common biomarkers found in fecal matter.
Purpose of the Study:
- To investigate the presence and origin of steroidal compounds in New York Bight sediments.
- To evaluate the potential of specific steroids as indicators of sewage contamination in marine environments.
Main Methods:
- Analysis of sediment samples collected from the New York Bight.
- Identification and quantification of steroidal compounds using advanced analytical techniques.
Main Results:
- Sediments contained significant concentrations of coprostanol and 24 beta-ethyl coprostanol.
- The detected steroidal compounds were confirmed to be of sewage origin.
Conclusions:
- Coprostanol and 24 beta-ethyl coprostanol are reliable indicators of sewage input in marine sediments.
- These steroids can be utilized as effective sewage tracers for monitoring marine pollution.
