Kathryn Rosica of the Chemical Manufacturers Association raised an interesting point in her letter (EHP vol. 102, p. 1006). Neither the term "glycol ethers" nor the term "ethylene glycol ethers" strictly identifies a class of chemicals whose members all share a common distinctive toxicological profile. As Rosica correctly noted, "Higher molecular weight ethylene glycol monoethers that have been...

Past studies on the toxicological effects of ethylene glycol alkyl ethers as well as the recent data on these chemicals in Japan are reviewed. Only a few researchers have participated in the study of ethylene glycol alkyl ethers in Japan. The effects of ethylene glycol alkyl ethers on testis and embryotoxic effects of ethylene glycol monomethyl ether (EGM) have been studied, as has the teratoge...

ally produced organic material and its majority is used in the production of polymers and derivatives. Between a variety of processes the thermal cracking of hydrocarbons in the presence of steam (steam cracker) is mostly used. Regardless of the process type, all plants require process analytical equipment to collect reliable and accurate process data for process control, product quality, and p...

this study was aimed to study the ways of removing dormancy period and accelerating pre-sowing tuber germination to provide simple tools to apply by farmers. for this purpose, intact tubers, exposed tubers to released ethylene and sliced tubers were examined in respect to germination characters, bud length, starch, anthocyanin and chlorophyll contents and amylase activity. relative amount of an...

of AF performance. that contain EG has been reponed to result in irreversible damage to renal, hepatic, cardiovascular, and central nervous systems, and is a cause of death in household pets and other animals.2-4 It is not known why some animals ingest EGcontaining products. Although there are reports suggesting that the "sweet" taste of EG, and of products containing it, may lead to ingestion ...
