Efficient detection of polycyclic aromatic hydrocarbons and polychlorinated biphenyls via three-component energy transfer.

Microscale detection of polychlorinated biphenyls using two-step laser mass spectrometry

Microprobe two-step laser desorption/laser ionization mass spectrometry ( LMS) is used as a new analytical technique for the detection of polychlorinated biphenyls (PCBs). Three standard Aroclor solutions (Aroclor 1232, 1242, and 1262) and three samples of activated carbon spiked with Aroclor 1242 are examined. All the PCBs present in the Aroclor solutions are clearly identified using LMS. The ...

Occurrence, Fate and Treatment Methods of Polycyclic Aromatic Hydrocarbons, Polychlorinated Biphenyls, Dioxins and Furans: A Mini Review

Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), dioxins and furans are persistent organic pollutants with well-known toxicity and carcinogenic activity. These organic pollutants have the tendency to bioaccumulate, present little or no biodegradation and subsequently, could cause a menace to the ecosystems and human health. This review discusses the occurrence, fate an...

Polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and chlorinated pesticides in background air in central Europe – investigating parameters affecting wet scavenging of polycyclic aromatic hydrocarbons

Concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and chlorinated pesticides (CPs) were measured in air and precipitation at a background site in central Europe. ∑ PAH concentrations in air and rainwater ranged from 0.7 to 327.9 ng m and below limit of quantification (< LOQ) to 2.1× 10 ng L. The concentrations of PCBs and CPs in rainwater were < LOQ. ∑...

In Situ Stabilization of Persistent Organic Contaminants in Marine Sediments

Microprobe two-step laser desorption/laser ionization mass spectrometry (μLMS) is used as a new analytical technique for the detection of polychlorinated biphenyls (PCBs). Three standard Aroclor solutions (Aroclor 1232, 1242, and 1262) and three samples of activated carbon spiked with Aroclor 1242 are examined. All the PCBs present in the Aroclor solutions are clearly identified using μLMS. The...
