| Fine particulate matter (PM-2.5) in the atmosphere has serious implications for the environment and human health. A linked system consisting of a Particle-Into-Liquid Sampler (PILS) and ion chromatographic analysis allow for PM measurements to be taken on a near continuous basis (every 15 minutes), providing crucial information about changes in the concentrations and composition of pollutants in the air over a given period of time. A Tapered Elemental Oscillating Microbalance (TEOM) is used to measure the total mass of the particulate matter and to monitor the presence of heavy metals in the air. Heavy metal emissions have been observed to be products of automobile wear, waste combustion and industry, and are tested every eight hours using ICP-MS. As the Los Angeles basin has enormous traffic flow through it, the concentration and effects of heavy metal emissions on local health and ecology are of great importance. |
