镇痛剂的非那宗类型，包括propyphenazone，氨基比林，安替比林，确定在固体废物和渗滤液的主要城市萨格勒布，克罗地亚，以及在土壤和地下水下面的垃圾填埋场。所有结构鉴定和定量分析均采用高分辨率气相色谱/质谱法进行。固体废物的分析表明，propyphenazone和氨基比林是其中最丰富的具体人为化合物在垃圾填埋场，而安替比林只检测到痕量浓度。由于垃圾填埋场没有任何保护屏障，严重污染的垃圾渗滤液羽流迅速渗入由高渗透性冲积沉积物组成的下层土壤，最终到达地下含水层。因此，在填埋场下方的地下水中检测到高浓度（高达67微克/升）的异丙安替比林和氨基比林。然而，氨基比林似乎是强烈衰减的含水层部分附近的垃圾填埋场，而propyphenazone表现出相当高的持久性和流动性的渗滤液羽。
Analgesics of the phenazone type, including propyphenazone, aminopyrine, and antipyrine, were determined in solid waste and leachate from the main landfill of the city of Zagreb, Croatia, as well as in soil and groundwater below the landfill. All structural identifications and quantitative analyses were performed using high-resolution gas chromatography/mass spectrometry. The analyses of solid waste revealed that propyphenazone and aminopyrine were among the most abundant specific anthropogenic compounds in the landfill, while antipyrine was detected only in trace concentrations. Since the landfill does not include any protective barrier, heavily contaminated landfill leachate plume penetrates rapidly into the underlying soil, which is composed of highly permeable alluvial sediments, and eventually reaches groundwater aquifer. As a consequence, propyphenazone and aminopyrine were determined in high concentrations (up to 67μg/L) in groundwater below the landfill. However, aminopyrine seems to be strongly attenuated in the aquifer section near the landfill, while propyphenazone showed a rather high persistence and mobility in the leachate plume.
