“…The enrichment factor (EF) is used for identifying the crustal and non-crustal origin of elements [38], and it is applied to particulate matter collected in filters [14,39], plants/lichens [32,40], and sediments [41]. The enrichment factor of the element was determined for each sample, using the reference values of soil composition (Table S1) [42] and taking Si as the crustal reference element [43], according to Equation (1):…”

This study aimed to understand the influence of industries (including steelworks, lime factories, and industry of metal waste management and treatment) on the air quality of the urban-industrial area of Seixal (Portugal), where the local population has often expressed concerns regarding the air quality. The adopted strategy was based on biomonitoring of air pollution using transplanted lichens distributed over a grid to cover the study area. Moreover, the study was conducted during the first period of national lockdown due to COVID-19, whereas local industries kept their normal working schedule. Using a set of different statistical analysis approaches (such as enrichment and contamination factors, Spearman correlations, and evaluation of spatial patterns) to the chemical content of the exposed transplanted lichens, it was possible to assess hotspots of air pollution and to identify five sources affecting the local air quality: (i) a soil source of natural origin (based on Al, Si, and Ti), (ii) a soil source of natural and anthropogenic origins (based on Fe and Mg), (iii) a source from the local industrial activity, namely steelworks (based on Co, Cr, Mn, Pb, and Zn); (iv) a source from the road traffic (based on Cr, Cu, and Zn), and (v) a source of biomass burning (based on Br and K). The impact of the industries located in the study area on the local air quality was identified (namely, the steelworks), confirming the concerns of the local population. This valuable information is essential to improve future planning and optimize the assessment of particulate matter levels by reference methods, which will allow a quantitative analysis of the issue, based on national and European legislation, and to define the quantitative contribution of pollution sources and to design target mitigation measures to improve local air quality.

“…Nonetheless, HM detection techniques that decrease or eliminate matrix destruction, facilitate direct, easy and rapid determination of ultra-trace heavy metals in solid samples are becoming increasingly attractive and popular, particularly for field studies [37]. Detection techniques such as instrumental neutron activation analysis (INAA), photoacoustic spectroscopy, and laser-induced breakdown spectroscopy (LIBS), have been employed in phytoremediation studies as they facilitate multi-elemental analysis on the tissue and cellular level [38,39]. LIBS offers rapid detection and real-time monitoring; however, further improvement and optimization is needed to improve its stability, reduce interference, accuracy, and sensitivity of the spectrum, and improve detection under various conditions [39].…”

Effectively dealing with hazardous and recalcitrant pollutants such as heavy metals (HMs) has become a global challenge with limited options available for reprieve. This is true for Pacific Island Countries and Territories (PICTs) which have witnessed significant economic transitions and substantial increases hazardous waste depositions. Although several physico-chemical remediation techniques exist, the economic and geographic limitations of PICTs render them impractical for the region. Phytoremediation, a plant-based remediation technology which exploits hyperaccumulator plants to extract, accumulate and/or stabilize HMs, has received significant interest as a sustainable and non-intrusive remediation option. Nonetheless, improving the application and efficiency of phytoremediation programs not only requires a better understanding of the fundamental mechanisms governing HM accumulation and tolerance in plants, but also demands fast and reliable spectroscopic techniques for in-situ analysis. This review critically examines the current practices in phytoremediation and its prospects for the treatment of HM-contaminated sites in PICTs. We also review the limitations of traditional spectroscopic techniques such as inductively coupled plasma mass spectroscopy/atomic emission spectroscopy (ICP-MS/ AES) and the promise of novel techniques such as field portable X-ray fluorescence spectrometry (FP-XRF), atmospheric pressure discharge plasma (APDP) and lab on chip (LOC) in phytoremediation studies.

“…Soil contamination has gained considerable attention as potential source of human and ecological risk over a large area in the southern Portugal and southwestern Spain in correspondence to the Iberian Pyrite Belt (IPB), the largest volcanogenic massive sulfide ore of the world (Ca ´novas et al 2008;Ferna ´ndez-Caliani et al 2008;Canha et al 2010). In this region, Riotinto, about 90 km NW of Sevilla, emerged since the antiquity as the main center of a massive and prosper mining industry.…”

Phytostabilization is a green, cost-effective technique for mine rehabilitation and ecological restoration. In this study, the phytostabilization capacity of Erica australis L. and Nerium oleander L. was assessed in the climatic and geochemical context of the Riotinto mining district, southwestern Spain, where both plant species colonize harsh substrates of mine wastes and contaminated river banks. In addition to tolerating extreme acidic conditions (up to pH 3.36 for E. australis), both species were found to grow on substrates very poor in bioavailable nutrients (e.g., N and P) and highly enriched with potentially phytotoxic elements (e.g., Cu, Cd, Pb, S). The selective root absorption of essential elements and the sequestration of potentially toxic elements in the root cortex are the main adaptations that allow the studied species to cope in very limiting edaphic environments. Being capable of a tight elemental homeostatic control and tolerating extreme acidic conditions, E. australis is the best candidate for use in phytostabilization programs, ideally to promote early stages of colonization, improve physical and chemical conditions of substrates and favor the establishing of less tolerant species, such as N. oleander.
