Bisphenol A in hazardous waste landfill leachates
TL;DR: The levels of bisphenol A in hazardous waste landfill leachates collected in Japan in 1996 were determined by gas chromatograph/mass spectrometer (GC/MS) and some samples exceeded the EC50 or LC50 levels for aquatic biota.
Journal ArticleDOI
Gas chromatographic investigation of acrylamide formation in browning model systems.
TL;DR: Relatively high levels of acrylamide (753 microgram/g of ammonia) were formed from ammonia and acrolein heated at 180 degrees C in the vapor phase, suggesting that ammonia andacrolein play an important role in acrieslamide formation in lipid-rich foods.
Journal ArticleDOI
Quantities of bisphenol a leached from plastic waste samples.
Takashi Yamamoto,Akio Yasuhara +1 more
TL;DR: To quantify the leaching of bisphenol A into water, various samples of plastic waste were cut into small pieces, soaked in water for two weeks at room temperature in the dark, and the concentration in the water determined by gas chromatography/mass spectrometry (GC/MS).
Journal ArticleDOI

TL;DR: In this paper, the presence of several organic substances in landfill leachates in Japan was investigated and approximately 190 compounds were detected using several analytical methods, including organic phosphates and phthalates, which originate from plastic additives.
Journal ArticleDOI
Mobile sources of atmospheric polycyclic aromatic hydrocarbons in a roadway tunnel
TL;DR: In this article, the average concentration of the major oxy-PAHs found in the guardrail dust samples were 6.9±0.77μg/g for pyrene, 5.5± 0.76μg /g for fluoranthene, and 2.6± 0.30μg for phenanthrene.
