Pyrolysis gas chromatography coupled with infrared identification of eluted peaks confirms that paraquat is pyrolyzed into chloromethane and 4,4'-dipyridyl at smoking temperatures and above. This reaction occurs at 610 degrees C to completion in small amounts in an inert atmosphere. The toxicity of 4,4'-dipyridyl remains to be determined. Pyrolysis of contaminated marijuana also produces the same two products, although detection at low limits is difficult with this procedure.
热解气相色谱法结合洗脱峰的红外鉴定证实，在吸烟温度及以上时，百草枯会热解为氯甲烷和4,4'-联吡啶。该反应在610摄氏度时在惰性气氛中少量发生并完成。4,4'-联吡啶的毒性尚待确定。受污染大麻的热解也会产生同样的两种产物，不过用此方法在低限检测较为困难。
