The Geochemistry of Pesticides
2007The widespread use of synthetic pesticides since their introduction in the early twentieth century has represented the most extensive release of synthetic compounds that Earth's ecosystems have ever experienced. Predicting the full implications of this phenomenon for the health of living organisms requires an understanding not only of the biological ...

From the previous chapter is should have become obvious that the distribution or partitioning of chemical elements is essentially controlled by rock-forming processes. The terrestrial planets with their initially chondritic bulk composition differentiated into a metallic core and a silicate mantle during a very early stage of our solar system’s history.

Journal of the American Oil Chemists' Society, 1966
AbstractLipids, particularly the glycerides, terpenes, sterols, and hydrocarbons, have properties conducive to their preservation either in original or transformed state and are significant constitutents of the geochemical biomass. The occurrence of phytane, pristane, and fatty acids in Precambrian sedimentary rocks 2.7 billion years old has been ...
