3.1.5 Conclusioni Dall insieme dei risultati illustrati nelle precedenti tabelle è possibile trarre alcune semplici considerazioni: - I valori di concentrazione in atmosfera al livello del suolo in tutti i casi esaminati sono molto modesti; gli stessi risultano inferiori in media di un ordine di grandezza rispetto ai relativi valori di standard di qualità dell aria. Occasionalmente è possibile il verificarsi di concentrazioni apprezzabili di biossido di azoto come valore stimato sulla media oraria di picco all interno degli intervalli considerati - Anche i valori di deposizione delle polveri risultano davvero modesti rendendo piuttosto laboriosa un apprezzabile misura strumentale - Il complesso dei valori ottenuti nelle rappresentazioni grafiche confermano sostanzialmente gli andamenti e le distribuzioni stimate tramite il modello ISCLT, tenuto conto ovviamente che le simulazioni ottenute con quest ultimo si basavano sulla elaborazione di un intervallo di tempo quarantennale. - I recettori che rilevano i valori maggiori sono il numero 6 ed il numero 1 di coordinate UTM rispettivamente di (693911,932558) e (692533,933410). I valori riscontrati presso tali recettori sono prossimi ai valori di massimo assoluto ottenuti durante i campionamenti; ciò confermerebbe l ottimo posizionamento dei campionatori. 60
