Description
Results of comprehensive experiments on the biological methylation of lead are reported. In contrast to other experiments in these attempts have been made to transfer methylgroups of different compounds and their C-14-labelled analogues to inorganic lead, lead-210 and ionic organic lead compound such as PbMe3OAc, PbEt3OAc and PbEt3Cl by microbiological activity. In none of the numerous experiments PbMe4 or PbEt3Me could be detected as the product of biological methyl transfer. Experiments with ionic organic lead salts yielded lead tetraalkyls like PbMe4 and PbEt4 only as a result of chemical reactions. (orig.)
Abstract (German)
Die Ergebnisse umfangreicher Experimente zur biologischen Methylierung werden vorgestellt. Im Gegensatz zu anderen Experimenten ist in diesen versucht worden, durch Mikroorganismen Methylgruppen verschiedener Methylgruppendonoren gezielt auf anorganisches Blei, anorganisches Blei-210 und ionische organische Verbindungen wie PbMe3OAc, PbEt3OAc und PbEt3Cl uebertragen zu lassen. In keinem der Experimente konnte PbMe4 oder PbEt3Me als Produkt eines biologischen Methylgruppentransfers festgestellt werden. Die Experimente mit ionischen organischen Bleisalzen ergaben PbMe4 und PbEt4 als Ergebnis chemischer Reaktionen. (orig.)Additional details
