: Laboratory experiments on microbial decomposition and on the contribution of diplopods to organic matter decomposition in soil were combined with field studies to reveal the major points of heavy metal effects on the leaf litter decomposition process. The study focused on the accumulation of organic litter material in heavy metal-contaminated soils. Microbial decomposition of freshly fallen leaves remained quantitatively unaffected by artificial lead contamination (1000 mg kg(-1)). The same was true for further decomposed leaf litter material, provided that the breakdown of this material was not influenced by faunal components. Although nutrient absorption in diplopods is affected by high lead contents in the food, this effect alone, however, was shown not to be sufficient for the massive deceleration of the decomposition process under heavy metal influence which could not only be observed in the field but occurred in microcosm studies as well. Reduced reproduction and lower activity of the diplopods most likely were responsible for the observation that lead-influenced diplopods enhanced microbial activity in soil only in a lesser degree than uncontaminated animals did. This effect is assigned to represent the main reason for decreased decomposition rates and the subsequent accumulation of organic material in heavy metal-contaminated soils.

ZusammenfassungDargestellt wird die erfolgreiche Behandlung eines Patienten mit jahrelangem Asthma bronchiale, allergischer Rhinitis, Anaphylaxie und einem Grand-Mal-Anfall mit Mytilus edulis pearl (Miesmuschel). Dabei erfolgte die Mittelbestimmung durch die Empfindungsmethode von Dr. Divya Chhabra. Sowohl die Mittelfindung als auch die Leitsymptome des verordneten Arzneimittels werden erläutert. Durch die Behandlung von 2014 – 2020 konnte die Asthmamedikation reduziert, die Infekthäufigkeit und -schwere konnten erheblich gesenkt und Arbeitsunfähigkeitszeiten konnten vermieden werden. Durch die durchgehende pneumologische Kontrolle können der erfolgreiche Verlauf und die stabile pulmologische Situation gezeigt werden.
