“…3B), similarly to results noted by Vardaka et al (1995) on the leaves of holm oak (Quercus coccifera L.). Similar results were also obtained by Nanos & Ilias (2007) when studying the effect of deposition of cement dust on the leaves of the European olive (Olea europaea L.). The smallest particles can clog stomata, thus reducing the concentration and accessibility of CO 2 independent of the effect on light phase of photosynthesis and transpiration (Naidoo & Chirkoot, 2004;Abdel-Rahman & Ibrahim, 2012;Burkhardt & Grantz, 2017).…”

“…In our study, P. serotina accumulated less PM on its leaves, which could protect it from the higher negative impact and could be another reason why this shrub is more tolerant to stressful conditions. Lowering the rate of photosynthesis due to the presence of PM accumulated on the surface of leaves can result from changes in the optical properties of the leaves and the decrease in radiation reaching the chlorophyll antenna, due to absorption or reflection by PM (Nanos & Ilias, 2007;Chauhan, 2010).…”

“…Conversely, PM also has a negative impact on plants (Armbrust, 1986;Hirano et al, 1995;Naidoo & Chirkoot, 2004;Nanos & Ilias, 2007). Particles accumulated on the surface of leaves can absorb and scatter light rays, preventing them from accessing the chloroplast freely (Hirano et al, 1995).…”

Particulate matter accumulation -further differences between native Prunus padus and non-native P. serotina Received: 14 April 2017; Accepted: 23 June 2017 Abstract: Particulate matter (PM) is one of the most harmful inhaled pollutants. Where pollutants have been emitted into the atmosphere, the most effective method for cleaning the air is through phytoremediation, whereby plants act as biological filters. PM has a negative impact on plants, but knowledge of PM effects on the photosynthetic apparatus is limited. In European forests, species of the genus Prunus L. play a key role in the composition of the forest understory and urban as well as industrial plantings. Shrubs of the native P. padus L. and closely-related invasive alien P. serotina Ehrh. are particularly widespread. Thus, both are good model species in which to study the impact of PM pollution. The aim of this study was to assess the accumulation of PM in the context of leaf morphology and amount of epicuticular waxes on foliage, and the efficiency of the photosynthetic apparatus of P. padus and P. serotina. The study was conducted under controlled conditions using two variants of dust, cement and roadside PM. In addition, we analyzed the absorption of dust by leaves dividing it into three fractions by size (10−100 µm, 2.5−10 µm and 0.2−2.5 µm). Results showed that both P. padus and P. serotina accumulate PM mostly on the surface of their leaves ( S PM), rather than in the wax layer ( W PM). P. padus accumulated higher amounts of PM than did P. serotina. The higher presence of PM on leaves of P. padus resulted in a reduction of the efficiency of the photosynthetic apparatus, manifested by lower rates of photosynthesis and chlorophyll a fluorescence, coinciding with an increased stomatal resistance. A strong negative correlation was found between the amount of PM accumulation and the efficiency of the photosynthetic apparatus in P. padus, but not in P. serotina. We have concluded that alien P. serotina is more tolerant to the conditions of stress caused by PM pollution than is the native P. padus, which may partly explain its success in the invasion in Europe.

“…For example, cement kiln dust reduced 73% of the photosynthesis in green beans [22], while ash reduced up to 90% of the rate of photosynthesis of apple trees [23]. Nanos and Ilias [24] described the effects of cement dust, such as a reduced stomatal conductance and transpiration rate of olive trees. Similarly, Shukla et al [25] reported that the highly alkaline nature of the cement dust resulted in the reduced chlorophyll content of dusted plants.…”

Abstract:The Xinjiang Region in Northwest China is known as the "dust center" of the Eurasian mainland. Dust on the leaf surface affects overall plant development. While emphasis was on studying the impacts of industrial dust particles on crop development, the effect of natural dust deposition on the physiological parameters of cotton had not been studied before. The objective of this study was to examine the effects of dust deposits on cotton leaves and to estimate their impact on crop development and yield. For this purpose, an experiment was set up having two treatments and a control. In Treatment 1, cotton leaves were cleaned with water at three-day intervals or after a natural dust fall. In Treatment 2, 100 g·m −2 of dust was applied at 10-day intervals. The control received neither additional dust nor cleaning. In all of the treatments, stomatal conductance, leaf temperature, biomass and yield were measured. The results show a 28% reduction in yield and 30% reduction in OPEN ACCESSWater 2015, 7 117 stomatal conductance of the dust treatment compared to the control treatment. This indicates blocking of the stomata on the top of the leaf surface. In addition, the canopy temperature of the dust-applied leaves was always higher than the control and treatment.

“…Introduzindo poeira de cimento em talhões de Pinus sylvestris à guisa de adubação, Kloseiko;Tilk (2006) comprovaram, após dois meses, que a acidez do solo e os parâmetros fotossintéticos medidos por fluorescência da clorofila não foram afetados pelos tratamentos, mas estes reduziram significativamente a concentração de hexoses em acículas de um ano de idade. Diminuição dos níveis totais de clorofila e da relação a:b, rebaixando a taxa fotossintética e a produção de plantas de oliveira expostas a poeira de cimento foram relatados por Nanos;Ilias (2007). Embora plantas do deserto (Zygophyllum prismatocarpum) tenham sido afetadas pela deposição de poeira, diminuindo o teor de clorofila, inibição da assimilação de CO 2 e do transporte de elétrons, van Heerden et al (2007) concluem que tais sintomas são reversíveis pela lavagem da poeira provocada pela chuva.…”

ResumoO objetivo deste estudo foi analisar o efeito das emissões de poeira de uma usina de cimento sobre o nível de clorofila de seis espécies arbóreas. Quantificou-se o teor de clorofila mensalmente, durante um ano, em árvores de dois locais distintos: um sob a influência da poeira de cimento e outro distante 50 km de tal tipo de emissão. Os pigmentos foram extraídos com dimetilsulfóxido, e a sua concentração medida por espectrometria. Abstract Chlorophyll content of six tree species under influence of cement dust. The present study aimed to analyse the effect of a cement plant emmissions of dust on chlorophyll content of six tree species. Chlorophyll content was evaluated monthly during a year on trees growing at two different places: one under the influence of cement dust and the other 50 km far from this type of emmission. Pigments were extracted with dimethylsulphoxide and its concentration measured by spectrometry. Araucaria angustifolia, Mimosa scabrella, Ocotea puberula and Schinus terebinthifolius showed higher chlorophyll concentration at polluted environment in comparison to control, while Pinus taeda and Matayba elaeagnoides performed the inverse manner. Under dust environment, the highest values in Araucaria, Schinus and Ocotea were observed during Winter, while Pinus, Mimosa and Matayba did reach peak values in middle Spring. At the control environment, Araucaria and Mimosa showed uniform values during entire year, while Ocotea and Matayba showed peaks in middle Autumn and decreased values in Winter. Schinus performed reduced values in direction Winter-Spring and Pinus presented level increase in the same direction. Keywords: Cement emissions; leaf pigments; air pollution; pollution by cement; seasonal variation. INTRODUÇÃOOs estudos dos efeitos ecofisiológicos em vegetais devido à interferência que o homem causa ao ambiente natural assumiram nas últimas décadas importância cada vez maior. Devido às dificuldades de controle e as interações múltiplas, não são muitos os estudos desenvolvidos sobre as descargas industriais poluentes e seus efeitos na vegetação. É conhecido que as usinas de cimento emitem poeira que, quando misturada à água, produz um precipitado com elevado pH, tóxico para os seres humanos, animais e vegetais. Segundo observações de Scheffer et al. (1969), nas proximidades dessas indústrias foi verificada uma deposição de partículas da ordem de 1g.m -2 .dia -1. As espécies podem apresentar diferentes graus de tolerância à ação da poeira de cimento, como foi comprovado por Iqbal;Shafig (2001). Além disso, os autores relatam que, devido à grande quantidade de cálcio fornecida diariamente, em solos ácidos o pH é paulatinamente elevado, concluindo que, apesar de ocorrer uma melhora nas propriedades estruturais do solo, observaram um
