Sublethal effects of PCBs and PCB replacements in fish
Marine Chemistry, 1983Abstract The environmental impact of some PCB replacements was compared with a PCB mixture, Aroclor 1254, by measuring the induction of the mixed function oxidase (MFO) system of the liver of brook trout ( Salvelinus fontinalis ). The magnitude of response was not always related to the tissue concentration of the test compounds or to similarities in ...

Due to the suspected carcinogenic nature of polychlorinated biphenyls (PCBs), a high degree of interest in the analysis and identification of these compounds in transformer oil has developed. The paper reports the identification of Aroclors 1242, 1254, and 1260 in transformer oil samples brought to the laboratory for analysis.

ABSTRACTAn outbreak of poisoning, characterized clinically by hyperpigmentation and a chloracne‐like eruption, broke out in mid‐Taiwan in Feburary 1979. Probably over a thousand persons were affected. The source of poisoning was found to be a specific brand of rice bran oil which was contaminated accidentally with polychlorinated biphenyls (PCB).

The Electric Power Research Institute's $7 million, five-year research program to find a way to manage PCB pollution is discussed. PCBs are used in two types of sealed electric equipment: 1) transformers that raise or lower the voltage of a power line; and 2) capacitors on utility poles that help maintain constant voltage in homes.

Due to rapid increases in printed circuit board (PCB) complexity and lack of research progresses in PCB routing algorithms over the years, routing has become a bottleneck in overall circuit board design time. Today, a high-end PCB typically takes significant tedious manual efforts to complete the wiring and this problem will only get worse for future ...
