Mining activities and associated waste materials pose significant environmental challenges, including soil, water, air contamination, along with health risks to nearby populations. Despite the harsh conditions of metal-enriched soils nutrient-poor substrates, certain plants known as metallophytes thrive in these environments. This study examined vascular flora Sardinia’s abandoned mining sites, a focus on identifying their potential role phytoremediation. A comprehensive floristic checklist...
Environmental contamination due to human activities is a worldwide problem that has led the development of different remediation techniques, including biotechnological approaches such as phytoextraction and phytostabilization. These techniques take advantage pioneer plants naturally develop tolerance mechanisms survive in extreme environments. A multi-technique multi-disciplinary approach was applied for investigation Helichrysum microphyllum subsp. tyrrhenicum samples, bulk soil,...
The mitigation of metals contamination is currently a crucial issue for the reclamation mine sites. Indeed, wastes are often disposed in open dumps and consequently pollutants subjected to dispersion surrounding areas. In this study, potential use Helichrysum microphyllum subsp. tyrrhenicum phytostabilization was evaluated ex situ conditions. Ninety specimens were randomly selected planted three substrates (reference substrate, waste materials, with compost). Mineralogical compositions...
Phytoremediation and the use of suitable amendments are well-known technologies for mitigation petroleum hydrocarbon (PHC) contaminations in terrestrial ecosystems. Our study is aimed at combining these two approaches to maximize their favorable effects. To this purpose, Helichrysum microphyllum subsp. tyrrhenicum, a Mediterranean shrub growing on sandy semiarid soils, was selected. The weathered PHC-polluted matrix (3.3 ± 0.8 g kg−1 dry weight) from disused industrial site employed as...
AbstractTailings and mine dumps are often pollutant sources that pose serious environmental threats to surrounding areas. The use of pioneer vascular plants extract or stabilize metals is considered among the more effective tailing reclamation techniques. study aimed at evaluating phytoremediation potential Pinus halepensis in abandoned mine-tailing (SW-Sardinia, Italy). Plant ability tolerate high Zn, Pb, Cd concentration their accumulation roots aerial parts were assessed greenhouse...
Arsenate, As(V), and arsenite, As(III), are the most available arsenicals present in soil solutions, particular mine polluted substrates, cause several symptoms of toxicity plants (like inhibition seed germination reduction seedling development). For these reasons, seeds studies essential for design phytoremediation activities sites. Seed development Helichrysum microphyllum subsp. tyrrhenicum, were evaluated at 15 °C using various concentrations As(V) As(III) (0–500 mg/L 0–200 mg/L,...
Arsenate, As(V), and arsenite, As(III), are the most available arsenical species that present in soil solutions, particular mine polluted substrates. As(V) As(III) cause several symptoms of toxicity plants, such as inhibition seed germination, reduction root shoot growth. In this context, seeds germination studies essential for design phytoremediation activities sites. Seed seedling development Helichrysum microphyllum subsp. tyrrhenicum , were evaluated at 15°C under two forms As different...
