“…A biorremediação é o processo de tratamento que utiliza a ocorrência natural de microrganismos e/ou plantas para degradar substâncias toxicamente perigosas transformando-as em substâncias menos ou não-tóxicas. Este processo é um mecanismo de estímulo de situações naturais de biodegradação, para a limpeza de derramamentos de óleos, e tratamento de ambientes terrestres e aquáticos contaminados com compostos xenobióticos (substância sintética que polui o meio ambiente) (Sánchez-Castro et al, 2023).…”

“…Entre os métodos de recuperação in situ, alguns dos processos de remediação são tidos como importantes, e consistem na melhoria ou recuperação de solos contaminados de forma natural, física, química e biológica, reduzindo a carga de contaminante, a concentração, a mobilidade ou a toxicidade deste contaminante em um determinado local (Sánchez-Castro et al, 2023).…”

“…In semi-arid regions, AMD is linked to water availability and only becomes apparent during rainfall events, which are common in semi-arid Mediterranean climates. During mining activities, runoff water can carry particulate matter and soluble material, including potentially toxic elements (PTEs) [ 10 , 11 ]. It should be noted that the pH values of these waters can range from 2 to 6.…”

“…Various publications have discussed the recovery options for Portman Bay, including studies and experiments related to the remediation of runoff waters that mix with acid mine drains and reach the beach area [ 10 , 15 , 33 ]. The meteoric waters are contained within the exposed section of the bay, resulting in the formation of a shallow lagoon during wet periods.…”

This paper evaluates an experimental wetland as part of a pilot soil reclamation project in a mining area. The wetland was constructed using materials of mining origin from the area; most reactive materials of acid pH were stabilised using limestone filler. The study selected macrophytes that are tolerant to potentially toxic elements (PTEs) and resistant to salinity, namely Phragmites australis, Juncus effusus, and Iris pseudacorus. These macrophytes were then placed in pots containing substrates composed of different mixtures of topsoil, peat, and mining waste (black or yellow sand). A thorough analysis of the physicochemical and mineralogical characteristics of the materials included studies of PTE mobilisation. This study emphasises the significance of the rhizosphere in directing the transfer of PTEs to the plant and the correlation between the substrate and the development of plant defence mechanisms, such as the formation of Fe-plates. Scanning electron microscopy was used to highlight these aspects and validate the results of the analytical determinations. These wetlands can be proposed as a phytoremediation strategy for areas affected by mining and maritime influence. They are easy to construct and remain stable, providing important ecosystem services such as the natural attenuation of acid mine drainage, support for vegetation development and fauna, and a clean ecosystem.

“…It has been identified as the third most significant threat to soil functions in Europe and Eurasia, fourth in North Africa, fifth in Asia, seventh in the Northwest Pacific, eighth in North America, and ninth in sub-Saharan Africa and Latin America [1]. Although most pollutants, such as the heavy metals Cu and Zn, have anthropogenic origins, some contaminants can occur naturally in soils as components of minerals and may become toxic at high concentrations [1, 5,6].…”

Heavy Metal-Based Fungicides Alter the Chemical Fractions of Cu, Zn, and Mn in Vineyards in Southern Brazil

This study aimed to evaluate Cu, Zn, and Mn fractions in vineyard soils in two important wine-growing regions in Latin America, which have soils with different soil organic matter (SOM) and clay contents. Soils were collected from vineyards aged 35, 37, and 39 years (Serra Gaúcha) and 13, 19, and 36 years (Campanha Gaúcha). In each region, soils were collected from a non-anthropized area, and in the oldest vineyards, the collection was conducted on and between the planting lines. The available and total Cu, Zn, and Mn contents were analyzed in addition to the chemical fractions. The ΔCu, ΔZn, and ΔMn were also calculated by subtracting the contents of each fraction of the vineyards from the reference areas. The use of fungicides promotes increased metal contents in vineyard soils. In soils with high SOM contents, Cu tended to increase in the organic fraction in surface and depth. In contrast, Zn increased in the residual fraction, and Mn increased in most bioavailable fractions. Cu and Zn increased their contents in soils with low SOM and clay contents in the organic and mineral fractions. Mn accumulated in the mineral and residual fractions.
