Thallium behavioral effect

HUMAN TOXICITY DATA Toxicological data reported in humans varies according to the specific soluble thallium compound, (thallium acetate) oral-human LDLo 12 mg/kg unre-ported-human LDLo 26 mg/kg unreported-child LDLo 8mg/kg. (thallium iodide) oral-man TDLo 286 mg/kg toxic effects behavioral effects. 

Formation of open adlayers via UPD is not a universal phenomena. Other metals such as lead, thallium and bismuth form close-packed mcommensurate monolayers and exhibit an effect which has been termed electrocompression. This refers to a gradual compression of the monolayer in the region between the monolayer deposition and bulk deposition regions. There is a slow reduction of the monolayer lattice parameter until it is about 3% compressed with respect to the bulk metal [22 - 23]. This type of behavior is expected for close-packed commensurate monolayers on the basis of effective medium theory [24].
