“…Adicionalmente, quando a espécie apresenta os fatores inferiores a 1, mas com alta tolerância ao ambiente, ela também pode ser considerada fitoestabilizadora (YANG et al, 2014). LEITE, 2020). É uma técnica de remediação no próprio local contaminado e evita contaminações secundárias que ocorreriam com o deslocamento da matéria, além de manter a camada superficial do solo, que por meio de outros métodos teria a fertilidade exaurida pela remoção (TAVARES et al, 2013).…”

“…O fato é que mediante a ampla distribuição das hiperacumuladoras no reino vegetal, é impossível que em todas espécies os mesmos mecanismos estejam sendo utilizados (BARZANTI et al, 2011). Essas plantas devem crescer rapidamente e produzir significativa biomassa, porém o maior acúmulo de metais pesados interfere nessa produção (OLIVEIRA & LEITE, 2020). Dependendo do grau de estresse, priorizam o investimento em recursos e energia para a defesa, ao invés do crescimento vegetal (FU et al;.…”

“…entre experimentos realizados em campo e em laboratório(OLIVEIRA & LEITE, 2020). Em condições naturais, os metais são misturados e menos disponíveis, além de sofrerem influência do clima e simbiontes do solo, portanto é mais confiável para testar verdadeiramente o potencial de plantas fitorremediadoras(HASSAN & AARTS, 2011;SCHNEIDER et al, 2013).Zonas agrícolas, urbanas e industriais estão sendo usadas para avaliar as diferentes técnicas existentes.…”

The practical utility, positive aspects and disadvantages are shown in this mini-review by means a practical formula to calculate the dosage of chlorine sanitizers (CS), which provides the amount of chlorine being used in the solution in gram (g) or milliliters (ml) and two figuras i) concentrations as calculated for chlorinated sites that handle or process food and ii) the advantages and disadvantages of the CS. The CS are widely used in the agribusiness sector widely used in the agribusiness sector worldwide, however, produce chloramine, toxic, carcinogenic to humans. Alternatives to the use of chlorine are needed such as ozone (O3), hydrogen peroxide (H2O2), peroxyacetic acid or peracetic (CH3CO3H), ultraviolet rays with a wavelength of 250 to 275nm by presenting germicidal activity. Studies are needed to reduce the cost of implementing these technologies in business.

“…It also boasts rapid growth, substantial biomass production, and an extensive deep root system (Balliana et al, 2017; Silva & Rezende, 2017). This species has been proven for phytoremediation of soil contaminated with copper (Rangel et al, 2023) and lead (Martínez & Dussán, 2018; Oliveira et al, 2017); herbicides: sulfentrazone (Ferraço et al, 2017; Madalão et al, 2017) and tebuthiuron (Ferreira et al, 2021; Mendes et al, 2021); diesel fuel oil (Balliana et al, 2017); and other types of contaminants such as those present in dumps (Barbosa et al, 2021) and steel mill waste (Dantas de Oliveira & Leite, 2020).…”

Soil contamination caused by fossil fuels and biofuels can alter the chemical and physical properties of soil, limiting its use for agricultural, residential, and recreational purposes. Phytoremediation offers a cost‐effective and manageable solution to mitigate these environmental impacts that can be applied to large areas. The aim of this study was to evaluate Canavalia ensiformis (jack bean) growth and nutrition during the remediation of B10 biodiesel in artificially contaminated soil. The experimental design was fully randomized, with four replications and three contamination levels with B10, 0%, 1%, and 2% vol/wt, evaluated over 20, 40, and 60 days after sowing. Plant growth was assessed: shoot and root dry biomass, height, number of leaves, leaf area, and plant nutrition: macro‐ and micronutrient vegetable tissue. Dry biomass of shoots and roots, plant height, the number of leaves, and the leaf area decreased significantly in inverse proportion to the level of contamination. Twenty days after sowing, C. ensiformis growing in B10‐contaminated soil reduced the nitrogen and potassium concentrations, while phosphorus and sulfur increased, and calcium and magnesium remained unaffected. However, all except potassium tended to equilibrium after 60 days of sowing. Regarding micronutrients, manganese increased after 20 days of sowing, while iron decreased, and copper and zinc remained unchanged. Despite its growth and nutrition limitations, C. ensiformis is a viable option for phytoremediation in areas contaminated with hydrocarbons. Its nitrogen absorption capacity makes it an ideal natural fertilizer for the remediation of fuel‐contaminated soils.

The steel residues application (SR) in sandy soils, under a proper handling management, can result in a benefits range, among which, the soil acidity correction. This study investigated the gralunometric composition of three slags and one exhaustion powder from a steel mill, in the municipality of Marabá-PA, in addition to the ability of soil pH correction. To identify the granulometric fractions were used number 8, 10, 16 and 18 mesh sieves. The pH correction experiment were made in factorial scheme, evaluated 3 doses of each RS (1.5 t ha-1, 2.0 t ha-1 and 2.5 t ha-1) in vases with Neosol, for 60 days. Residues from the steel refining (EAFS, LDS and EAFD) showed a particle size predominantly under 1.00 mm, and promoted pH values above to 7.0. The blast furnace slag obtained domain of particle sizes > 2.00 mm, with 77% of the material retained in the sieves, and their soil disposition promoted similar results to dolomitic limestone, used traditionally to pH correction in acid soils, representing an alternative in soil preparation. Others residues also showed the soil pH correction capacity, although the used dosages proved to be above the ideal, with values above 7 and alkalinity tendency. The necessity of an investigation of EAFS, LDS and EAFD residues dosage are essential to pH soil correction, in order to condition the soil to pH ranges considered ideals (6-6.5).
