Über dieses Buch

Worldwide concern in scientific, industrial, and governmental com­ munities over traces of toxic chemicals in foodstuffs and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to provide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. Until now there has been no journal or other publication series reserved exclusively for the diversified literature on "toxic" chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wild­ life, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authorita­ tive publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancillary legislation.

Cyanobacteria and pesticides
Abstract
The cyanobacteria or blue-green algae (BGA) are the group of microorganisms having an oxygen-evolving photosynthetic system. Many genera are aerobic nitrogen-fixers and some others also are known to grow on molecular nitrogen in the anaerobic and symbiotic state. The combination of an oxygen-evolving photosynthesis with the oxygen-sensitive nitrogen-fixing system is rare among the microbes. In addition, they have the ability to invade otherwise uninhabitable sections of the environment, namely, hot springs, icelands, volcanic soil, and sewage wherein the combined-nitrogen content either is absent or the temperature is in either of the extremes or a variety of natural or artificial chemicals is present. The cyanobacteria have a role in binding the soil particles and also add nitrogenous compounds to the soil. The global combined nitrogen of cyanobacteria both free-living and symbiotic forms (Azolla, Cycas, etc.) is important today when we think of the protein demand of the developing countries tomorrow. Thus, study of the abundance of cyanobacteria in natural ecosystems and rice fields (where they grow mostly in tropical climates) is important.

Review of Methods for the Determination of Ethylenethiourea (Imidazolidine-2-Thione) Residues
Abstract
Ethylenethiourea [imidazolidine-2-thione (ETU), Fig. 1] has been known to be a possible degradation product of ethylenebis(dithiocarbamate) (EBDC, Fig. 2) fungicides for over 30 years (Clarke et al. 1951, Fishbein and Fawkes 1965, Czegledi-Janko 1967, Bontoyan et al. 1972).

Compartmentation and reliability of sampling procedures in organochlorine pollution surveys of cetaceans
Abstract
The study of the effects of chemical pollution on wildlife basically straddles three scientific disciplines: chemistry, ecology and zoology. The research chemist must elaborate systems for detecting and precise quantifying of the different compounds found in the tissues of living organisms, and must study those properties of such compounds which explain the basic processes of transfer and accumulation in the ecosystem. The ecologist must put this data together with his own knowledge of the dynamic processes which regulates the ecosystem, both on a general level (movements of air and water masses), and on a particular one (trophic chains, migrations, etc.). Finally, the zoologist must bring his knowledge to bear on the biology of the species which are to be studied, in order that the results maybe correctly evaluated and not biased by the particular characteristics of the animals sampled (physiological or reproductive state, age, etc.).
