Aquatic sediments contain small amounts of organic matter which have been contributed from the land by water and wind erosion, from the water column, and from the sediment itself by biological activity. These fluxes include variable loads of pollutants and their degradation products. Base-line studies of the organic components of contemporary surface sediments and of layers from cores are urgently needed so that the pollutants can be distinguished from the natural compounds. Such analyses require precise analytical procedures capable of identifying pollutants and natural compounds, both expected and unexpected. Computerized gas chromatography-mass spectrometry provides this capability and the option of further processing the stored data long after acquisition. The ways in which computers can be used to process mass spectral data are discussed and some applications are described. The use of one advanced computerized gas chromatography-mass spectroscopy system for the analysis of an estuarine sediment is described in detail. The presence of phthalate esters, polynuclear aromatic hydrocarbons and partially degraded crude oil, as well as certain natural lipids, is demonstrated.

Polychlorierte Biphenyle (PCB) gewinnen neben den pestiziden chlororganischen Kohlenwasserstoffen als potentiell toxische Substanzen unter hygienisch‐toxikologischen Aspekten zunehmende Bedeutung. Wesentliche Vermittler bei der Verbreitung dieser Substanzen in der Umwelt sind die Atmosphäre und das Wasser. Vom hygienischen Standpunkt sind Untersuchungen über die Belastung von Oberflächenwässern, die der Trinkwassergewinnung dienen, erforderlich. Da die Analytik der PCB eng mit dem analytischen Nachweis chlororganischer Insektizide verbunden ist und beim Nachweis beider Substanzgruppen wechselseitig Störungen auftreten können, besteht das Hauptproblem der PCB‐Analytik in der Abtrennung der die Be‐stimmung störenden chlororganischen Insektizide, insbesondere des p, p′‐DDE. Eine dünnschicht‐chromatographische Bestimmungsmethode wird beschrieben, die sowohl eine Trennung als auch eine quantitative Bestimmung folgender Substanzen bzw. Substanzgemische ermöglicht: p, p′ ‐DDT, p, p′‐DDD, p, p′ ‐DDE, y‐HCH, Chlophen A‐60, Aroclor 1254, 2,4,4′‐Trichlorbiphenyl und 2,3,4,5,6,2′,5′‐Heptachlorbiphenyl. Eigene Untersuchungsergebnisse über die PCB‐Belastung von Wässern werden angegeben.

Publications from 1969 through 1974 reporting organic and spark source mass spectrometric studies on environmental samples have been compiled. Emphasis is placed on pollutants identified, but some methods and techniques are discussed. The 396 reports cited vary from those reporting hundreds of identified pollutants to those describing the analysis of only one sample containing one or a few pollutants. Reports concerning forensic, synthetic and standard samples, and analyses for drug residues. metabolites and degradation products are not included
