“…Following the degradation of the OM content, soluble organic metal complexes are generated that enhance metal bioavailability [33]. Although, Eid et al [1,17] suggested that sewage sludge could be a valuable fertilizer to improve growth, yield, and plant constituents of crops, sewage sludge should be utilised with caution and in controlled circumstances in order to diminish the metal accretion in soil and the subsequent metal uptake by plants.…”

“…The cumulative uptake of metallic elements by plants involves and relies on a number of soil characteristics, the components of the sewage sludge and the concentration used, the species phenology and physiology, the biochemistry related to the rhizosphere, climate characteristics, the influence of chelation, and chemical metal speciation [17,34,35]. The principal source of metal accretion and filtering in plants is thought to be the root system, which takes up metals at a slow rate, especially if they are available in significant quantity, and thus inhibits or reduces their mobility to the areal plant components [24,36].…”

“…The simple estimation of the BCF can serve as a rough insight into the range of metal uptake, but it does not reflect more detailed site-specific conditions of the soil [14]. Valuable mathematical approaches and regression models can be applied to forecast specific dependent variables (e.g., metal concentrations within plant tissues) using variables independent of the soil (e.g., metal concentration, pH, and OM content) [13,[15][16][17]. Once generated, such models can be employed to determine the impact of sewage sludge use with respect to crops such as A. esculentus.…”

Prediction models were developed to estimate the extent to which the metals Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn were taken up by the fruits, the leaves, the stems, and the roots of the okra plant, Abelmoschus esculentus (L.) Moench., grown under greenhouse conditions in soil modified with a spectrum of sewage sludge concentrations: 0, 10, 20, 30, 40, and 50 g/kg. All the metals under investigation, apart from Cd, were more concentrated in the A. esculentus roots than in any other organ. Overall, the sum of the metal concentration (mg/kg) within the varying plant tissues can be ranked in the following order: roots (13,795.5) > leaves (1252.7) > fruits (489.3) > stems (469.6). For five of the metals (i.e., Cd, Co, Fe, Mn, and Pb), the BCF was <1; for the remaining four metals, the BCF was >1, (i.e., Cr, 1.074; Cu, 1.347; Ni, 1.576; and Zn, 1.031). The metal BCFs were negatively correlated with the pH of the soil and positively correlated with soil OM content. The above-ground tissues exhibited a TF < 1 for all metals, apart from Cd with respect to the leaves (2.003) and the fruits (2.489), and with the exception of Mn in relation to the leaves (1.149). Further positive associations were demonstrated for the concentrations of all the metals in each examined plant tissue and the corresponding soil metal concentration. The tissue uptakes of the nine metals were negatively correlated with soil pH, but positively associated with the OM content in the soil. The generated models showed high performance accuracy; students’ t-tests indicated that any differences between the measured and forecasted concentrations of the nine metals within the four tissue types of A. esculentus failed to reach significance. It can, therefore, be surmised that the prediction models described in the current research form a feasible method with which to determine the safety and risk to human health when cultivating the tested species in soils modified with sewage sludge.

“…A presença de metais pesados, é uma das principais limitações ao uso do lodo na agricultura, pois pode causar a contaminação do solo, lençol freático, plantas e animais (Eid et al, 2021). A concentração de metais pesados presentes no lodo pode variar de acordo com o tipo de esgoto que a estação de tratamento recebe, sendo que o esgoto industrial, em comparação ao esgoto doméstico, possui concentração de metais pesados mais elevada (Tytła et al, 2016).…”

O esgoto é constituído pela água usada nas atividades diárias, que foi usada para lavar roupa ou louça, no banho, na descarga do banheiro ou na pia. Esta água residual contém impurezas, constituída de uma mistura de detritos, restos de alimentos, detergentes, urina, fezes e outras substâncias. Quando jogado diretamente no meio ambiente, gera odor forte e fétido, além de conter bactérias nocivas, causadoras de enfermidades. Quando devidamente tratado, o lodo é chamado de biossólido, e sua reutilização agroflorestal pode ser uma alternativa atraente. Desse modo, o presente estudo tem como objetivo identificar o biossólido, caracterizar o processo de tratamento e a composição do material, relatar suas utilidades associadas a agricultura e recuperação de áreas degradadas, assim como normativas e legislações que vigoram a respeito desse resíduo. O trabalho foi conduzido por meio de levantamento bibliográfico que reúnem assuntos relevantes sobre o biossólido, características do biossólido, lodo de esgoto, utilização na agricultura, a fim de disponibilizar um conhecimento mais esclarecedor e relevante para a comunidade científica na área de tratamento de lodo de esgoto, convertendo-o em biossólido, sua caracterização e aplicação na agricultura nos mais variados aspectos.

“…Uma das principais restrições ao uso do lodo na agricultura é a presença de metais pesados, que pode causar a contaminação do solo, lençol freático, plantas e animais (EID et al, 2021). Entretanto, em razão da enorme variação e interação entre lodos e solos, não existem resultados conclusivos sobre a efetiva contaminação do ambiente quando do uso agrícola deste resíduo (Agoro et al, 2020;Lin et al, 2020;Zoghlami et al, 2020).…”

Este trabalho teve como objetivo avaliar o efeito da aplicação de lodo de esgoto sobre os teores de metais pesados e sódio no solo e nas folhas do girassol (Helianthus annuus L.). O experimento foi realizado em área de Nitossolo Háplico do Instituto de Ciências Agrárias da Universidade Federal de Minas Gerais em Montes Claros - MG. Os tratamentos corresponderam a quatro doses de lodo de esgoto da ETE Montes Claros – MG (0; 10; 20 e 30 t ha-1, em base seca), com seis repetições, no delineamento em blocos casualizados. Foram avaliados os teores de Ni, Pb, Cd, Cr, Zn, Cu e Na no solo e na planta. A aplicação de doses de até 30 t ha-1 de lodo de esgoto na adubação de girassol não influenciou os teores de Ni, Pb, Cd, Cr, Zn, Cu e Na no solo e no tecido foliar da planta, não havendo limitação ao uso agronômico deste resíduo para os elementos citados.
