Klaus Füsser give similar species, either by reduction of a mixed surface anhydride or by thermal treatment of low valency surface “salts”. Here systems with V, Mo and Fe will be discussed, with a short look to Ti, Co, Ni and Cu... can be fixed to silicagel by a redox cycle (O./500°C; CO/600°C); in the resultin

Klaus Füsseride, and an MAC of 0.5 μg 1. for so-called total pesticides. Problems arise in the development of suitable methods because of two basic difficulties; there are hundreds of pesticides that could be monitored and the MAC sets difficult analytical performance requirements - ie a method needs to be reas

Klaus Füssercumulate, uptake from water is the predominant route. Because aquatic organisms have to ventilate very large amounts of water to satisfy their oxygen requirements, exposure to extremely low concentrations in water can lead to high concentrations in the organisms..The concentrations of many micropoll

Klaus Füssers formed, notably xenoliths in kimberlites. Outside cratonic areas where kimberlites typically occur, diamonds have been recorded in alpine peridot-ites and gravels associated with them. Graphite pseudomorphs after di-amonds occur in the Beni Bousera peridotite massif (Kornprobst, 1969) within garne

Structural and petrological investigations suggest that shearing starts in the lower crust at very high temperature, befo
