Hb J-Antakya or alpha 2 beta (2)65(E9)Lys----Met in a Turkish family and Hb complutense or alpha 2 beta (2)127(H5)Gln----Glu in a Spanish family; correction of a previously published identification.

Almost 10 years ago we reported in this journal the characterization of Hb Hacettepe or alpha 2 beta (2)127(H5)Gln----Glu. Unfortunately, we have to conclude that the original characterization of this Turkish variant was in error. The corrected data are presented in this short communication. The variant (alpha 2 beta (2)65(E9)Lys----Met) was (re)named Hb J-Antakya, after the city where the family resides. An abnormal Hb, observed in a Spanish family and named Hb Complutense, had the beta 127 Gln----Glu substitution, erroneously assigned to the Turkish variant.

Accumulation model for solutes leaching from polymeric containers.

An accumulation model for predicting the equilibrium solution concentration of leachables migrating from polymeric containers has been applied to the leaching of several solutes from a blend of a styrene-butadiene-styrene block co-polymer and polypropylene. The model considers three accumulation-limiting mechanisms: total available pool, solute solubility and solute partitioning. Equations relating a solute's solvent-water partition coefficients (Po/w and Ph/w) and its polymer partitioning properties have been developed. With these equations, one can predict leachable accumulation from the container weight, solution volume and the solute's partition coefficients. The maximal accumulation of the leachable in solution will be the lowest value predicted via the three accumulation-limiting mechanisms.
