Measurement of polycyclic aromatic hydrocarbons and other pollutants

Abstract

A single point study of atmospheric pollution has been carried out in Granada (Spain); suspended particulate matter, sulphur oxides, ammoniac, nitrogen dioxide and polycyclic aromatic hydrocarbons were determined. There were variations in relation to the month and the day of the week. The PAHs have been determined through HPLC, with a mobile phase of acetonitrile-water (75-25). The results of measurements of benzo(a)pyrene were between 1.006 and 0.485 micrograms m-3 in two different periods of sampling.

Polypyrrole Chitosan Cobalt Ferrite Nanoparticles Composite Layer for Measuring the Low Concentration of Fluorene Using Surface Plasmon Resonance

“…Many methods have been introduced for measuring the concentration of fluorene. The best known methods that were used to measure low concentrations of fluorene are high performance liquid chromatography (HPLC), [18] liquid chromatography-fluorescence detection (LC-FLD), [19] and laser-induced fluorescence probes. [20] These met-hods require expensive instruments, and they require special chemical knowledge to conduct experiments and analyze the data.…”

Reduced Graphene Oxide Decorated with Polypyrrole Nanoparticles Layer for Detection of Pyrene Using Surface Plasmon Resonance Technique

“…6 Some of the health effects associated with exposure to pyrene are skin cancer, bladder cancer, lung cancer, 7,8 shrinkage of kidneys and increased size and weight of the liver. 9,10 Numerous methods are used to measure the concentration of PAHs, including pyrene such as high performance liquid chromatography (HPLC), 11 the combination of HPLC and fluorescence, 12 sensor based on molecularly-imprinted polymers (MIPs), 13 liquid chromatography-fluorescence detection (LC-FLD), 14 laser-induced fluorescence probe, 15 and the microwave technique. 16 The disadvantages of these methods are that they require special chemical knowledge and the equipment required is expensive.…”
