The main goal of this laboratory is to identify, quantify and study the structure of the organic pollutants specific to North-East region of Romania. This laboratory is coordinated by the researchers from Faculty of Chemistry of our University.

Physic-chemical analyses laboratory is focused on the following research directions:

  • monitoring the organic and inorganic pollutants from natural matrixes
  • studies concerning the establishing of the structure of unknown compounds
  • studies of mechanisms of reactions in natural conditions of volatile organic compounds
  • applying new methods of how to identify, separate, concentrate and determine environment pollutants
  • the elimination of some pollutant agents from wastewater

The research team has the ability to obtain important results using an efficient infrastructure: is has participated in international projects, has remarkable results on a national level (their own research made up for the lack of information from the literature regarding the chemical behaviour of some pollutants in the environment – using advanced analytical means of quantification of some organic pollutants from various natural matrixes), has results published in specialized magazines ISI rated.

In addition to tracking indicators monitored by the National Environmental Agencies in Romania, our laboratory analysis is interested in other indicators such as follows:

  • quantifying the content of heavy metals present in the sediment powders (especially Pb), waters and soils
  • the quality of the pH precipitates, conductivity, acidity and alkalinity, chemical composition

Keeping in mind that in the Al.I. Cuza University in Iasi, there are activities of monitoring and analysis at local and regional level, especially in distress situations (accidents, floods, illegal and abusive emissions etc.) the new Laboratory for the identification, quantification and studying of volatile organic pollutants shall reunite the efforts of the environmental researchers by monitoring other indicators such as:

  • the identification of organic volatile compounds specific to the North – East region (alkanes, alkynes, aromatic hydrocarbons – BTX, alcohols, aldehydes, organic acids)
  • the identification of the chemical composition of sediment powders (the organic fraction)
  • the identification of persistent organic pollutants (POP-s) from waters and sediments
  • The quality of the precipitations – the content of organic matter from the precipitations – establishing the influence of the organic fraction on the pH of the precipitations

The performance criteria remain nonetheless the essence of the value and the requirements for any analysis. Hence the two conditions which must be fulfilled by any laboratory of European standard: objectivity and efficiency. The quality control activity will cover the pre-treatment phases, starting with nominating the quality objectives and continuing with equipment, sampling and personal site. This crucial objective will be carefully observed by a team of 2-3 specialists, which have graduated the courses organized by RENAR and EURACHEM Romania.

As deducted from the presentation of the situation on both national and international level, any contribution to the diminishing or the stopping of the anthropogenic aggressions on the environment is of utmost importance, through the mere fact that it contributes to the protection of the population and the ecosystems. The immense diversity of pollutants in all departments of the environment make their identification, quantification and control as complex as their immense number. Consequently, the present objective has as a purpose the identification and monitoring of organic volatile pollutants, characteristic to the North- East area of Romania.

The domain that is approached is new and very complex, on the one hand, due to the numerous members of the interdisciplinary team, the nature of the pollutants and the methodologies which will be used (electrochemical methods, spectral methods, high-resolution chromatographic methods, mass spectrometry), the modelling of the systems on the computer, the sketching of maps with spatial and temporal distribution of the concentrations. On the other hand, the complexity also arises from the big number of sampling sites, on the whole surface meant for monitoring, which brings with it a very vast amount of analysis (according to evidence and replicates)/site/month/year.

The novelty of our laboratory is the manner of theoretical and experimental approach to introducing monitoring as a mandatory activity

  • identifying and quantifying as instruments of qualitative and quantitative evaluation of pollutant organic volatile compounds;
  • identifying and quantifying as instruments of connecting the environmental policies and legislation of North East Romania to the European and international environment politics;
  • identifying and quantifying as promises for the future, for the abiding of the laws, the enhancement in the quality of life, the conservation of the biodiversity of the ecosystems
  • it considers the elaboration of a high performance methodology for the identification of some isotopes in the environment;

Acknowledging the situation regarding the pollution with volatile organic compounds on a national and international level, but especially, the need to contribute with our own data to the general European bigger picture, justifies the request for creating a Laboratory for the identification, quantification and studying of volatile organic pollutants in the CERNESIM Centre
