Effect of air pollution in the industrial area of Jeddah city, Saudi Arabia on three tree species Camphor (Cinnamomum camphora), Henna (Lawsonia inermis), and Bougainvillea (Bougainvillea spectabilis) has been studied with special reference to characteristics of leaves. These plant species were chosen because they are common and in the industrial and control areas. leaf area, number of stomata, stomata length and width and stomata pore width and length of these plant species were investigated. The results of this study with all trees species showed significant decrease in plant leaf area and stomata number in the industrial zone comparing with the control area. The results of those tree species indicated marked alteration in epidermal traits, with increased stomata length and width and stomata pore width and length collected from industrial site than those from control site. These changes in the leaf area and epidermal traits could be as indicator of environmental stress and can be recommended in the industrial areas for the early detection of air pollution.

The effect of industrial emissions on the levels of certain biochemical measurements in leaves 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. Overall results showed that the content of chlorophyll a and b, total chlorophyll, carotenoids and protein in the plant leaf of the trees growing in the industrial zone were less comparing with the leaves of the trees growing in the control area.

The Impact

This study was performed to investigate the impact of air pollution on leaf area and anatomical features of Melia azedarach L. trees, in urban areas with three demographical classes: location (I) industrial area, location (II) roadside area and free parts (control area) as a location (III) of Duhok city/Kurdistan Region-Iraq, during July 2021. The results demonstrated that the leaf area of selected plants' leaves in location I had reduced with no noticeable change in the average stomata density in the three locations I, II and Ⅲ. Meanwhile, the results of the most anatomical features of the blade (blade, lower cuticle, epidermis (both upper and lower) thickness, palisade layer height and spongy parenchyma width) in addition to midrib parameters (epidermis thickness (upper and lower), collenchyma and parenchyma layer width, phloem and xylem width and pith diameter) were decreased in both locations I, II, and with well-developed anatomical features in location III.

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.

Tolerance Indices

With the fast growing and excessive increase in industrial projects in Bengaluru, the level of pollution is also increasing. Metal-accumulating woody species have been considered for phytoextraction of metal-contaminated sites. The study examined the air pollution tolerance indices (APTI) of plant species around three industrial areas of south Bengaluru. The physiological and biochemical parameters, which are relative to leaf's water content (RWC), ascorbic acid content (AA), total leaf chlorophyll (TCh) and leaf extract pH were used to compute the APTI values and three heavy metals were selected (cadmium, lead and zinc) for analysis. The result shows that the most tolerant tree species with respect to ATPI and heavy metal concentration wereFicus religiosa, Azadirachta indicaandPongamia pinnata (L.). These plants can be considered as tolerant species in the industrial areas. The APTI values for remaining species are reported lower and are considered as sensitive species. Further studies on air pollution tolerance index with respect to three industrial areas of south Bengaluru indicated that the air pollution was maximum in Jigani industrial area and minimum in Electronic city.

Air pollution tolerance index (APTI) was calculated for various plant species growing in industrial area of Orai. The leaf samples collected from 24 tree species in the industrial area were used to determine their Air Pollution Tolerance Index (APTI) by calculating the ascorbic acid, chlorophyll, pH and relative water contents. The APTI values of less than 16 are reported in 19 species and they can be used as indicators of air pollution. The species Ficus religiosa (24.92), Zizyphus jujuba (21.84), Phyllanthus emblica (17.40), Cassia fistula (17.67) and Tamarindus indica (16.96) showed their moderate response by changing their biochemical contents and were identified as moderately tolerant to air pollution.

Depending on the characteristics of the industrial area, toxicity evaluation of human body, risk assessment and health impact assessment may directly cause cancer due to air pollution. Environmental data collection is from August 2018 to January 31, 2019, and the average, minimum, and maximum values of air pollution data respectively. According to the global data on global trends using the Big Data, high blood pressure is confirmed at 33rd place in the world, and myocardial infarction among the environmental diseases is confirmed to be lower than Korea. Disease that occurred in Jeolla province industrial complex considering the characteristics of our country was identified as representative. Air pollutants are considered to be the causes of allergic diseases in Korea. PM10 was found to be higher than the control area (28.8804348 (㎍ / ㎥), 31.7065217 (㎍ / ㎥) and 32.8532609 (㎍ / ㎥). The mean concentrations of PM2.5 in the middle and high exposure areas were lower than those of the control areas, but the highest in the intermediate exposure areas was 16.5978261 (㎍ / ㎥), 16.1086957 (㎍ / ㎥) and 17.1847826 (㎍ / ㎥) respectively. The relationship between the major variables of environmental exposure in Yeosu was confirmed to be correlated with high blood pressure, chronic obstructive pulmonary disease (COPD), bronchitis, cerebrovascular, diabetes, thyroid disease, sinus infection, anemia and pneumonia.
