متن کاملRelationship between PAHs Concentrations in Ambient Air and Deposited on Pine Needles
OBJECTIVES This study was carried out to determine whether or not pine needles can be used as passive samplers of atmospheric polycyclic aromatic hydrocarbons (PAHs) using the correlation between accumulated PAH concentrations in air (Ca, ng/m(3)) and those deposited on pine needles (Cp, ng/g dry). METHODS PAHs in ambient air was collected using low volume PUF sampler and pine needles was gat...
متن کاملA Passive Sampler for Atmospheric Particles
Preliminary investigation on the feasibility of size selective passive sampling for atmospheric particles was undertaken through laboratory simulated and outdoor sampling. The passive samplers used in the research were improved from passive sampler used for sampling atmospheric organic contaminants. Sampled particle size distribution was analyzed by MasterSizer 2000 laser particle size analyzer...
متن کاملAre pine needles bioindicators of air pollution? Comparison of organochlorine compound levels in pine needles and ambient air.
Levels of six PCB congeners and seven organochlorine pesticides were investigated and compared in ambient air and in pine needle samples. The applied methods are suitable for the analysis of PCBs and organochlorine pesticides in environmental samples and for their detection in recent intakes. DDE, HCB, lindane, PCB-28, PCB-52, PCB-101, PCB-138 and PCB-153 were found in all pine needle and air s...
متن کاملEvaluation of a passive air sampler for measuring indoor formaldehyde.
A passive air sampler, using 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole, was evaluated for the determination of formaldehyde in indoor environments. Chromatography paper cleaned using a 3% hydrogen peroxide solution was experimentally determined as being the optimum absorption filter for the collection of formaldehyde (0.05 microg cm(-2) formaldehyde). From a linear-regression analysis betwe...
