Monitoring air pollution close to a cement plant and in a multi-source industrial area through tree-ring analysis

Abstract: Thirty-two trace elements were examined in the tree rings of downy oak to evaluate the pollution levels close to a cement plant isolated in a rural context and an industrial area where multiple sources of air pollution are or were present. Tree cores were collected from trees growing 1 km from both the cement plant and the industrial area that are located 8 km from each other. The analysis of the trace elements was performed on annual tree rings from 1990 to 2016 using laser ablation inductively coupled plasma… Show more

“…Hierarchical clustering across the sites in our study found that 29 Si, 24 Mg, 43 Ca, 44 Ca and 209 Bi, 238 U, 232 Th, 34 S, 9 Be, 133 Cs clustered together and these represent sources such as the earth’s crust and the industrial processes, such as cement and marble industries [ 23 ]. For instance Cs has been linked with the erosion and weathering of rocks and minerals and as well as the fly ash from waste incinerators and coal burning power plants [ 33 ].…”

“…63 Cu, 202 Hg and 79 Br also clustered together and point to sources such as coal combustion and to some extent cement processing. Cu has been reported in emissions from cement plants [ 33 ]. Hg is associated with coal combustion [ 36 ].…”

“…Many studies focused on a handful of elements to identify environmental changes, either through acidification or the addition of heavy metals [71,[91][92][93][94][95][96][97][98]. However, most studies looked at the general elemental profile of tree samples to identify elements of interest or of higher concentration than expected [22,68,99]. The most studied element in dendrochemistry from this review is lead (Pb), with 91 articles including it within the scope of the research (Figure 6).…”

“…While promising, dendrochemistry is not without its difficulties and inconsistencies. Since the first applications of dendrochemistry, researchers in the field have continuously called for more research to fully understand the translocation and uptake of different elements by specific tree species [19][20][21][22][23][24][25][26]. The main reasons for the caution come from acknowledging that tree growth and elemental uptake depend on many factors [26].…”

“…Dendrochemical studies have been successfully utilized to study trace metal deposition in tree rings and have been widely used to monitor environmental changes in soil and atmosphere [55]. Alternative dendrochemical techniques have been used to study the effects of atmospheric pollution [56][57][58] and volcanic eruptions [59][60][61][62]. Wildfires generate large numbers of pollutants, including trace elements [63,64].…”
