Titre : Determination of environmental quality of water and soil samples collected from the selected areas of Gorce National Park Type de document : TFE / Mémoire Auteurs : Charlotte Racot, Auteur ; Olivier Janssens, Directeur de publication, rédacteur en chef Année de publication : 2017 Note générale : Le fichier numérique de ce document est disponible uniquement pour les membres de la Haute Ecole Louvain-en-Hainaut ainsi que ses étudiants. Veuillez vous connecter pour accéder à votre compte lecteur Langues : Français (fre) Mots-clés : Agronomie AIBT Erasmus Gorce National Park Pologne Index. décimale : TFE AIBT TFE Agro-industries et biotechnologies Résumé : Gorce National Park is supposed to be a protected area. However, pollution is ubiquitous. It comes from human wastes from tourists and local population, the management of meadows or it could come from industries in the south of Poland.
It is why, the aim of this study is the determination of the content of selected pollutants of water and soil in samples collected from the selected areas of Gorce National Park. But also an assessment of their overall environmental impact.
The different analyses include the use of analytical techniques. Several parameters such as temperature, oxygen indicator, biogenic indicator (e.g. nitrate, ammonia, phosphate) and salinity indicators (e.g. pH, hardness, conductivity) were measured on water samples.
Thanks to those, we were able to determine the quality of water and the concentration of Zinc, Cadmium and Lead in soil. The results showed that there is no pollution in the Kamienica creek. They also detected a slight pollution of those three heavy metals in the investigated soil samples.Note de contenu : Table of contents
