We have numerically modeled the breakdown of small quantities of several chlorinated hydrocarbons (CH3Cl, CH2Cl2, CHCl3, CCl4, C2H3Cl, and C2H5Cl) in a lean mixture of combustion products between 800 and 1480 K. This simulates the fate of p...

Lead and cadmium enter the municipal solid waste stream as components of a variety of consumer products. Average empirical data from several resource recovery plants were analyzed to obtain an estimate of the source and fate of the subject ...
Total human exposure: basic concepts, EPA field studies, and future research needs [0.03%]

The "irritation signaling" model proposed that a long term contribution to chronic bronchitis might result from the repeated delivery of "signals" resulting from temporary localized acidification of the bronchial epithelium by the action of...
Mobility of polychlorinated aromatic compounds in soils contaminated with wood-preserving oil [0.03%]
多氯芳香烃类化合物在防腐油污染土壤中的迁移性研究
