只有非常有限的信息可用于测量纳米颗粒的环境浓度。在这项研究中，荷兰的几个环境隔间被探测纳米颗粒的存在。筛选了不同类型的水中存在无机纳米颗粒（Ag、Au、TiO2）和有机纳米颗粒（C-60、C-70、[6,6]-苯基- c -61丁酸辛酯、[6,6]-苯基- c -61丁酸丁酯、[6,6]-双苯基- c -61丁酸甲酯、[6,6]-苯基- c -61丁酸甲酯）。分析了空气样品中纳米颗粒Mo、Ag、Ce、W、Pd、Pt、Rh、Zn、Ti、Si、B以及Fe和Cu的存在。采用ICP-MS、Orbitrap-HRMS、SEM和EDX进行调查。水样包括沙丘和河岸滤液、地表水和地下水、污水处理厂的进水、流出物和污泥，以及机场和港口附近收集的地表水。空气样本包括城市和农村样本，在空气、污水处理厂、进水、废水和污泥中检测到c -60，但在其他含水样品中检测不到，尽管检测限低至0.1 ng/L。C-70和功能化富勒烯均未检测到。通过SEM/EDX和ICP-MS验证了STP污泥和进水中Ag和Au纳米颗粒的存在。在空气中，某些金属的含量高达25m %，存在于纳米级的颗粒中。总体而言，空气样品中金属总质量的1%至6%存在于尺寸分数中
Only very limited information is available on measured environmental concentrations of nanoparticles. In this study, several environmental compartments in The Netherlands were probed for the presence of nanoparticles. Different types of water were screened for the presence of inorganic (Ag, Au, TiO2) and organic nanoparticles (C-60, C-70, [6,6]-phenyl-C-61-butyric acid octyl ester, [6,6]-phenyl-C-61-butyric acid butyl ester, [6,6]-phenyl-C-61-butyric acid methyl ester, [6,6]-bis-phenyl-C-61-butyric acid methyl ester, [6,6]-phenyl-C-71-butyric acid methyl ester, [6,6]-thienyl-C-61-butyric acid methyl ester). Air samples were analysed for the presence of nanoparticulate Mo, Ag, Ce,W, Pd, Pt, Rh, Zn, Ti, Si, B as well as Fe and Cu. ICP-MS, Orbitrap-HRMS, SEM and EDX were used for this survey. Water samples included dune and bank filtrates, surface waters and ground waters as well as influents, effluents and sludge of sewage treatment plants (STPs), and surface waters collected near airports and harbours. Air samples included both urban and rural samples.C-60 was detected in air, sewage treatment plants, influents, effluents and sludge, but in no other aqueous samples despite the low detection limit of 0.1 ng/L. C-70 and functionalised fullerenes were not detected at all. In STP sludge and influent the occurrence of Ag and Au nanoparticles was verified by SEM/EDX and ICP-MS. In air up to about 25 m% of certain metals was found in the nanosize fraction. Overall, between 1 and 6% of the total mass from metals in the air samples was found in the size fraction
