Biomarker information content

The concentration of individual biomarkers in a crude oil are relatively low (Peters and Moldowan, 1992 Figure 7), but their information content is significant and related to source, depositional environments, maturity, age, migration, and extent of biodegradation. The complete biomarker fingerprints obtained by MID are used extensively for the purpose of undertaking oil/oU or oil/source rock correlation studies. There are numerous papers and books which have documented the utilization of biomarkers in petroleum exploration only a few examples of the major applications will be... [Pg.3695]

Figure 7 The concentrations of individual biomarkers in a crude oil are relatively low but the complex nature of their structures means their information content is high. This diagram provides an indication of the approximate concentrations of individual steranes and terpanes in a t)fpical cmde oil.

This book presents information on evaluating sediment contamination and its effects on aquatic ecosystems. Contents include effective assessment methods effects on marine and fresh water benthos, plankton, and fish defining physical and chemical habitat conditions bioavalability influencing factors biomarkers acute and chronic toxicity study design collection methods and EPA management strategies. [Pg.100]

In routine analysis, arsenic in urine is usually determined. Recently, Karagas etal. (2002) proposed the use of toenail arsenic concentrations as a reliable biomarker of total As exposure reflecting arsenic intake by drinking water containing > 1 pg L kThe authors mentioned that urinary As may not be detected consistently in a population for which drinking water contents are primarily < 50 pg so that toenails may better provide risk information... [Pg.1341]

Pantothenic acid is measured in the blood, urine and food. Determination of blood and urinary pantothenic acid contents can be a biomarker for the evaluation of pantothenic acid status. Measurement of pantothenic acid in as many foodstuffs as possible gives important information for determining pantothenic acid status. For example, the Standard Tables of Food Composition in Japan 2010 records pantothenic acid contents for 1878 foodstuffs (Ministry of Education, Culture, Sports, Science and Technology 2010). The pantothenic acid content of a number of foodstuffs is shown in Table 20.1. [Pg.335]
