Sedimentary polycyclic aromatic hydrocarbons: the historical record
Science (New York, N.Y.)
|November 25, 1977
Summary
Researchers analyzed polycyclic aromatic hydrocarbons (PAHs) in Buzzards Bay sediment. The findings indicate that PAHs in this area mainly originate from burning fossil fuels.
Area of Science:
- Environmental Science
- Geochemistry
- Organic Chemistry
Background:
- Polycyclic aromatic hydrocarbons (PAHs) are organic compounds formed during incomplete combustion.
- Sediment cores provide a historical record of environmental conditions.
- Understanding PAH sources is crucial for environmental monitoring and risk assessment.
Purpose of the Study:
- To investigate the sources of polycyclic aromatic hydrocarbons (PAHs) in Buzzards Bay, Massachusetts.
- To establish a historical record of PAH deposition in the region.
- To determine the primary contributors to sedimentary PAH levels.
Main Methods:
- Analysis of polycyclic aromatic hydrocarbons (PAHs) using gas chromatographic spectrometry.
- Examination of three distinct sections from a dated sediment core.
- Application of analytical chemistry techniques for compound identification and quantification.
Main Results:
- Polycyclic aromatic hydrocarbons (PAHs) were detected in all analyzed sediment sections.
- Distinct PAH profiles were observed, indicative of specific source inputs.
- The composition of PAHs suggests a dominant anthropogenic origin.
Conclusions:
- Sedimentary polycyclic aromatic hydrocarbons in Buzzards Bay are predominantly derived from the anthropogenic combustion of fossil fuels.
- The findings highlight the significant impact of human activities on the local aquatic environment.
- This study provides valuable historical data for understanding PAH pollution dynamics.

01:25Aromatic Compounds: Overview
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.

01:13Five-Membered Heterocyclic Aromatic Compounds: Overview
Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom, respectively.
02:56The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
01:18Aromatic Hydrocarbon Anions: Structural Overview
Neutral hydrocarbons like cyclopentadiene with an odd number of carbon atoms and one intervening CH2 group in the ring are not aromatic. Cyclopentadiene with 4 π electrons does not satisfy the 4n + 2 π electron rule. Additionally, the intervening CH2 group is sp3 hybridized and lacks a vacant p orbital, thereby interrupting the overlap of p orbitals in a continuous manner and preventing the delocalization of π electrons throughout the ring.
Due to the absence of continuous overlap of p...

01:14NMR Spectroscopy of Aromatic Compounds
Aromatic compounds can be identified or analyzed using proton NMR and carbon‐13 NMR. Typically, aromatic hydrogens or hydrogens directly bonded to the aromatic rings are strongly deshielded by the aromatic ring current. Therefore, they absorb in the range of 6.5–8.0 ppm in proton NMR spectra. For instance, aromatic hydrogens directly bonded to the benzene ring absorb at 7.3 ppm. However, aromatic hydrogens of larger rings absorb farther upfield or downfield than the ideal range. Consider...
01:50Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
