“…Overall, the CW system removed sufficient amount of Ammonia Nitrogen, the mean removal percentages of Ammonia Nitrogen examined in this study for the first cycle i.e., in winter season shown in Table 3 and Figure 9 were 78-92%, 69-89% and 73-90% for Phragmites australis, Typha latifolia and Scirpus validus, respectively. And observed removal performance for the second cycle i.e., in summer season shown in Table 4 and Figure 10 was 78-91%, 70-88% and 73-90% for Phragmites australis, Typha latifolia and Scirpus validus, respectively and exceeds the removal amount examined by the authors (Silvestrini et al, 2019;Cano et al, 2019;Yalcuk and Ugurlu, 2009). The mean values of influent and effluent of Phragmites australis, Typha latifolia and Scirpus validus respectively are shown in Table 2.…”

The CWs were planted with Phragmites australis, Typha latifolia and Scirpus validus with sand and gravel. The leachate had been treated with two different cycles, first cycle was performed in the winter season whereas second cycle in summer, to differentiate the performance with seasonal variation. Chemical parameters of leachate pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids TSS, Ammonia-nitrogen (NH 3 -N), Nitrate-nitrogen (NO 3 -N), Total Phosphate PO 4 3-(TP) and heavy metals, Lead (Pb) and Copper (Cu) were tested with intervals of certain weeks. The tests result showed that all parameters experienced a considerable reduction in their concentrations. Significant reduction efficiencies were recorded for parameters, BOD with 53-82%, COD with 32-46%, TSS with 59-75%, NH 3 -N with 90-92%, NO 3 -N with 85-87%, and TP with 48-64%, and heavy metals Pb and Cu with 28-48% respectively in four weeks of the first cycle by all three plants. Whereas, in the second cycle, the removal efficiencies of BOD 78-93%, COD 63-76%, TSS 52-83%, NH 3 -N 90-91% and NO 3 -N 91-92% and heavy metals Pb and Cu with 21-58% respectively in five weeks were observed by all three plants. Along with the experimentation, United Nations Sustainable Development Goals UN SDGs are also highlighted. This study helps achieving tremendous SDGs accompanying treatment of leachate.

“…Phytoremediation technology is gradually being accepted and used as an effective method for regulating ecological stability and purifying water quality [57]. Phytoremediation techniques purify contaminated soil, water, and groundwater through various pathways, such as phytoextraction, phytofiltration, phytostabilization, phytovolatilization, and phytodegradation (Figure 1) [3,45].…”

Global Situation of Bioremediation of Leachate-Contaminated Soils by Treatment with Microorganisms: A Systematic Review

et al. 2023

This systematic review presents the current state of research in the last five years on contaminants in soils, especially in leachates from solid waste landfills, with emphasis on biological remediation. In this work, the pollutants that can be treated by microorganisms and the results obtained worldwide were studied. All the data obtained were compiled, integrated, and analyzed by soil type, pollutant type, bacterial type, and the countries where these studies were carried out. This review provides reliable data on the contamination of soils worldwide, especially soils contaminated by leachate from municipal landfills. The extent of contamination, treatment objectives, site characteristics, cost, type of microorganisms to be used, and time must be considered when selecting a viable remediation strategy. The results of this study can help develop innovative and applicable methods for evaluating the overall contamination of soil with different contaminants and soil types. These findings can help develop innovative, applicable, and economically feasible methods for the sustainable management of contaminated soils, whether from landfill leachate or other soil types, to reduce or eliminate risk to the environment and human health, and to achieve greater greenery and functionality on the planet.

“…As alternativas de SbN decentralizadas que podem ser eficazes no controle de escoamentos pluviais e descargas de poluentes são as biorremediações com wetlands construídas (ÁLVAREZ-ROGEL et al, 2020;BAL-DOVI et al, 2021;CANO et al, 2019;CANO et al, 2020;HERNÁNDEZ--CRESPO et al, 2017;JURCZAK et al, 2018;JURCZAK et al, 2019;KOTSIA et al, 2020;LIQUETE et al, 2016;MATAMOROS et al, 2020;MENDON-ÇA;NOLASCO, 2017;YANG et al, 2020), as infraestruturas de biofiltração com parques lineares em margens de rios (IZYDORCZYK et al, 2018;SYMMANK et al, 2020;SZKLAREK et al, 2018), trincheiras de infiltração e biovaletas vegetativas, jardins de chuva, pavimento permeável, telhados verdes e cisternas (EATON, 2018;MEI et al, 2018;RIECHEL et al, 2020;SHE;WEI;YOU, 2021). Os cursos de águas das áreas urbanas de São Paulo são envoltos em galerias pluviais e, dessa forma, as SbN integradas com as infraestruturas de drenagem urbanas são promissoras para mitigar o impacto da urbanização nas redes hídricas.…”

O livro Construindo sustentabilidade em contextos urbanos, parte da Coletânea Interfaces Ambiente, Saúde e Sustentabilidade: construindo diálogos e atuações interdisciplinares, representa dois aspectos importantes que são constantemente buscados no contexto da pós-graduação: a perenidade de um trabalho insistente de formação de talentos e produção de conhecimentos e a relevância das temáticas que trata, contemporâneas e estratégicas para o país. Num contexto desafiador, às vezes com poucos recursos e no qual nem sempre a pesquisa e a formação de alto nível são valorizadas, um trabalho contínuo e perene, como o realizado no Programa de Pós-Graduação Ambiente, Saúde e Sustentabilidade (ProASaS), traz lições inspiradoras. Este quinto livro da Coletânea é uma delas, principalmente porque resulta de trabalhos de discentes. Entendendo que no mainstream científico, a comunicação científica é parte importante do processo de construção dialógica do conhecimento, esta obra aborda uma temática atual, contemporânea, desafiadora e necessária.
