The impact of landfills on the local population is convinced Pollution S.r.I (Italy) to develop an analytical system for environmental pollution. Currently, surveys for environmental analysis are carried out discontinuously. Air samplers are taken at regular time intervals and canister are analysed in laboratory. As a results the absence of continuous monitoring and delayed response does not allow real time action and tracking of the pollutants.
Latest the HAPSITE GC-MS (Gas Chromatography-Mass Spectrometry)system provides insights on the analysis of volatile organic compounds (VOCs) in environmental hazardous waste treatment and industrial hygine. On site critical information can be achieved in fast and reliable way.
The process of continuous monitoring was then performed using portable micro gas-cinematographer (Vega-CG) and multi point sampler (vega-MPS) which also produced and distributed by Pollution S.r.I
Vega MPS has a function to send in sequence to Vega-GC the samples 'sucked' at different points inside or on the neighborhood of the landfill. This system consists in a network of pipes of inert material (PTFE) and the intake air is continuously pumped in each line to ensure fresh and not diluted samples. Between sampler and analyzer a concentrator EDU-3 from Airsense Analytics (Germany) has been placed to increase the sensitivity of the monitoring systems.
Using the MC-Plan software integrated in the computer of the Vega-GC, it is possible to record the chemical composition of the sampling point at the specific sampling time and to compare the concentration of each component with the TLV level (threshold limit value). If the threshold level is exceeded on one several points, an alert massage is sent by email or to the mobile phone through a remote PC to graphically display the concentration trend during last hour in order to perform a deep analysis.
