Evaluation of environmental pollutions on Pinus eldarica needles essential oil
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1
Abstract
Influence of environmental stress factors on both crop and wild plants of nutritional value is an important research topic. The past research has focused on rising temperatures, drought, soil salinity, but the potential effects of increased environmental contamination by human-generated pollution on plants have little been studied. Here it studied the influence of environment pollutions on essential oil analyses in Pinus eldarica. The needles of Pinus eldarica Medw. were collected from different regions of Isfahan in Iran (1: Around of industrial factories. 2: In city center with air pollution. 3: Around of high voltage pylons) and they were analyzed by using GC/MS. The 40, 15, 19 compounds were identified in industrial pollution, air pollution and electromagnetic pollution, respectively. The major components in needles of industrial region were: Octadecenoic acid (31.52%), α-pinene (14.95%), 3-carene (4.23%), β-pinene (3.151%). The major components in in needles of collected with air pollution were: α-pinene (52.57%), β-pinene (12.21%), Octadecenoic acid (7.19%), limonene (7.07%). The major components in needles of collected from electromagnetic region were: α-pinene (29.46%), β-pinene (12.32%), limonene (4.93%), Octadecenoic acid (4.92%). Air pollution resulted in density of a-pinene, so that density of a-pinene in urban region Pinus eldarica needles was highest. There was a direct relationship between environmental pollutions and essential oil chemical modifications of the three plants studied. These data collectively demonstrate that human-generated pollution can potentially constitute a stress to the plants.
