“…According to Maletsika and Nanos 38 , the application of dust originating from contaminated soil increases the aboveground biomass. In contrast, the low dose of applied soil dust in the present study did not affect the DW yield of the leaves in the two treatments (Table 2), while the risk elements contained in soil dust applied to the leaf surfaces increased the content of elements in the plant biomass (Table 2), similar to the results reported by Xiong et al 8 .…”

“…Arsenic limits stomatal conductance, thus decreasing the transpiration rate 50 . Maletsika and Nanos 38 carried out a similar study on plants exposed to dust. From their results, it is obvious that the applied dust had a negative influence on the transpiration and photosynthetic rates as well as stomatal conductance and the chlorophyll content.…”

In this study, we observed the effect of the application of soil dust enriched with risk elements (Cd, Pb, As and Zn) to leaf surfaces of lettuce (Lactuca sativa var. capitata) while it was grown under hydroponic conditions. This study aimed to determine how low soil dust particulate matter (PM) doses affected the activity of or damaged the photosynthetic apparatus and how the uptake of risk elements was associated with both epigenetic changes (5-methylcytosine content, i.e., 5mC) and stress metabolism. During the study, we obtained many results pertaining to risk element contents and biochemical (total phenolic content (TPC), malondialdehyde (MDA) content and the amount of free amino acids (AAs)) and physiological (photosynthesis parameters: net photosynthetic rate, transpiration rate, intercellular CO2 concentration, stomatal conductance, instantaneous water-use efficiency, maximum quantum yield of PSII, chlorophyll and carotenoid contents, and leaf water potential (WP)) plant features. The results showed an increase in MDA and 5mC. However, the transpiration rate, WP and free AAs decreased. In conclusion, contamination by very low doses of soil dust PM had no direct or significant effect on plant fitness, as shown by the TPC and 5mC content, which indicates that plants can overcome the oxidative stress caused by the accumulation of risk elements. From the above, we propose the use of epigenetic changes as biomarkers of potential changes in the activation of plant metabolism under stress caused by environmental pollution.

“…Plants can be used as a useful bio-indicators for the assessment of environmental pollution in the industrial areas (Tomasevic et al, 2004;Madejón et al, 2004Madejón et al, , 2006Gautam et al, 2005;Mingorance and Oliva, 2006). Several studies were carried out using plants as bioaccumulators or bio-indicators in environmental investigations (Celik et al, 2005;Aksoy and Demirezen, 2006;Yilmaz et al, 2006;Akguc et al, 2008;Maletsika and Nanos 2013;Saadullah, et al, 2014).…”

Particles matters accumulation and anatomical leaf properties of Camphor (Cinnamomum camphora), Henna (Lawsonia inermis), and Bougainvillea (Bougainvillea spectabilis) trees growing in the industrial zone in Jeddah - Saudi Arabia and Hada Al-Shame area (control) was done. The leaf properties of all tree species growing in the industrial and control showed that each stoma had a raised edge over the guard cell region. The guard cells appeared more shrunken on the polluted leaves as compared with unpolluted leave. The results indicated that the most deposition particles on leaf surfaces of all tree species were: soot (C) and soil dust with characteristic matrix elements (Si, Al, Mg, Ca, K); fuel oil particles rich in Al, Si, Ca, and Pb; coal ash particles containing C, Al, Si, K, Ca, S; and Pb. As a result, leaves of those plant species may be used as bio-indicators for the assessment of particular matters in the industrial areas.
