CANONICAL VARIATE ANALYSIS OF CHLOROPHYLL CONTENT IN PLANTS EXPOSED TO DIFFERENT LEAD CONCENTRATIONS IN AMBIENT AIR CONDITIONS
Journal Title: Civil and Environmental Engineering Reports - Year 2014, Vol 3, Issue 14
Abstract
This paper presents the results of biomonitoring of Pb in ambient air. For this purpose Italian ryegrass was used to evaluate Pb level. Additionally chlorophyll forms (a+b, a and b) were measured in leaves. Plants were exposed at 5 sites varying in environmental characteristics in the 2011 growing season. A similar set of plants was conducted in control conditions. Three 28-day long exposure series were performed. The aim of this study was to analyse the relation between Pb level and chlorophyll content in various exposure sites and series using multivariate analysis of variance. The analysis revealed variability of Pb and all chlorophyll forms contents in different exposure sites and series. The lowest level of Pb concentrations was noted at a sub-urban site together with the highest level of all chlorophyll forms contents. Canonical variate analysis could be a proper tool for a graphical data presentation of Pb level in plants exposed to various environmental conditions.
