The use of commercially available SPE cartridges is an attractive technique, because the volume of elution solvent is reduced and the cartridges can be used in different cleanup methods. C 8 retains OPPs because of its apolar characteristics, and it allows polar analytes to pass. This method has been used to clean up extracts from beef tissues (60,61,63). The opposite is true of polar stationary phases such as Florisil, which has been used to clean up extracts from marine mammal tissues (62). 

Monooxygenases are found in many living organisms bacteria, yeasts, insects, plants and mammal tissues. They are used for organic asymmetric reactions either in a more or less purified enzymatic form (cytochromes P-450) or in whole-cell microorganisms (bacteria, fungi).

Meat and Bone Meal is the rendered product from mammal tissues, including bone, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach, and rumen contents, except in such amounts as may occur unavoidably in good processing practices. It shall contain a minimum of 4.0% phosphorous (P), and the calcium (Ca) level shall not be more than 2.2 times the actual phosphorous (P) level.

Mammal tissue cells can be cultivated if cubic shaped microcontainers (300 x 300 x 310 pm ) with a wall thickness of 50 pm are used (Figure 4, left side). The injection molded PMMA structures possess small pyramidal rectangular holes (40 x 40 pm ) with smallest size (6x8 pm ) at the bottom side for the nutritious supply of ihQ cells (P). 

Clear images of biomolecules such as phosphoryl-choline, fatty acids, and lipids in mammal tissues can be readily obtained [22,24,28,94,95], The special resolution... 

In most of the mammalian tissues studied, there are two major isoforms of MT (termed MT-1 and MT-2), which differ slightly in amino acid sequence and net charge. These MT isoforms bind metals identically but are encoded by two distinct genes. Recently two other mammalian MT genes (termed MT-3 and MT-4) have been identified in certain mammal tissues (Palmiter et al. 1993), but their significance is not yet understood. In contrast, only one MT gene has been isolated from avian species, chicken, and turkey (Fernando and Andrews 1989). 

Uthe et al 2 have described a rapid semi-micro method for determining methylmercury in fish and crustacean and aquatic mammal tissue. The procedure involves extracting the methylmercury into toluene as methylmercury bromide, partitioning the bromide into aqueous ethanol as the thiosulphate - complex, re-extracting...

The issue of matrix effects that result in signal suppression (or possibly, enhancement) is a cause for concern, in that analyses may be subject to bias. Tomy et al. [116] report one of the first applications of isotopically labeled internal standards to the determination of HBCD diastereomers in complex matrix samples. The use of and labeled HBCD isomers, in principle, should reduce measurement bias, since quantitation is based on the ratio of coeluting HBCD species (i.e., the analyte and the internal standard) rather than absolute responses of the analytes. Analyte response may vary with instrument conditions and matrix effects however, the ratio remains constant. The use of isotopically labeled internal standards for the individual diastereomers is now common practice for BFRs [117]. HBCD isomers have been determined by LC—MS/MS methods in diverse sample types, including estuary [94] lake, river, and snow water samples [118] styrenic polymers [119] marine sediments [120] fish [121], marine mammal tissues [122—124] seaweed [125] foods [126] and human biological matrices [124,127].
