Semiquantitative determination of polychlorinated biphenyls in tissue samples by thin layer chromatography
A method is described for the analysis of polychlorinated biphenyl (PCB) compounds in tissue samples. Cleanup by hexane-aceto-nitrile partitioning and Florisil column chromatography are performed on samples before oxidative treatment to convert DDE to DCBP. PCB components are then determined semi-quantitatively by TLC. No prior separation of PCB from chlorinated pesticides is required. The lower l

A starling-deterrent wood duck nest box
In many parts of the United States, the starling (Sturnus vulgaris) has I become a serious competitor for nest boxes erected for wood ducks (Aix sponsa).

After that time dates of publication that appear on the covers are either incomplete or incorrect. For taxonomic purposes, for developing a chronological survey of a subject, or for other reasons, the exact date of publication of numbers in
