摘要

可卡因是一种非法毒品，世界各地的执法部门在缉获中经常发现。本文描述了一个罕见的案例，可卡因贩运沥青材料，可能以可卡因盐酸盐的形式。这些材料是在巴西联邦警察的一次行动中发现并在桶中缴获的。样品最初被提取出来，经斯科特测试呈阴性，但进一步的气相色谱联用质谱(GC-MS)筛选证实了可卡因的存在。然后，对样品进行定量GC-MS分析。在桶中发现的沉淀物质提取物中，可卡因的浓度从0.11至1.53纳克/10毫克不等。考虑到提取效率在57.44%左右，估计可卡因占桶沉渣重量的1.07 ~ 15.34%。

Cocaine Trafficking in Asphalt Material: An Unusual Report of Cocaine in Seized Drugs

Cocaine is an illicit drug commonly found by law enforcement in seizures around the world. This paper describes a rare case of cocaine trafficking in asphaltic material, possibly in the form of cocaine hydrochloride. The material was found and seized in barrels during an operation conducted by the Brazilian Federal Police. The sample was initially extracted and resulted negative for cocaine via Scott’s Test, but further screening by gas chromatography coupled with mass spectrometry (GC-MS) confirmed the presence of cocaine. Afterwards, samples were subjected to quantitative GC-MS analysis. The concentrations of cocaine ranged from 0.11 to 1.53 ng/10 mg in the extracts of precipitate material found in the barrels. Considering that extraction efficiency was around 57.44%, it is estimated that 1.07 – 15.34% of barrel’s sediment weight was constituted by cocaine.
