Representation of the stages of the study of the enzymatic degradation of polyurethane (PU): (a) docking, (b) molecular dynamics and in (c) the free energy profile of the proposed reaction mechanism.

Physico-chemical treatment of hospital laundry wastewater using aluminum sulfate, tannin and Moringa oleifera seeds aiming for the removal of pollutants and pathogens.

Graphical abstract of composite electrode as electrochemical material for the simultaneous determination of pesticides in surface water and its oxidation behavior study.

The contamination of ocean water with oil spills can be a potential problem for food security. The study investigated the presence of polycyclic aromatic hydrocarbons (PAH) and benzene, toluene, ethylbenzene, and xylene (BTEX) in fishes from the Brazilian coast and Rio de Janeiro (RJ) had the higher contamination among the samples.

Theoretical calculations are tools in predicting sustainable photosensitizing molecules, synthesized derivatives of chlorins and bacteriochlorins. The theoretical data obtained with the Gaussian 09 software using density functional theory (DFT) are similar to experimental spectroscopic data.

Homemade diffusive gradients in thin films (DGT) devices prepared with agarose (non-toxic hydrogel) to evaluate the lability of metallic species in Cará-Cará River, Ponta Grossa, Paraná, Brazil.

Here, we present the validation items studied and the distribution of the estrogen 17α-ethinyl estradiol in suspended particulate matter along a salinity gradient in Guaratuba Bay, South Atlantic, Brazil, during summer and winter.

From gamma irradiation of molybdenum oxide, reduced oxides (MoO_3-x) were obtained with expansion of the absorption spectral region. With the heterojunction formation between MoO_3-x and cadmium sulfide (CdS) quantum dots, better efficiencies for photocatalytic generation of hydrogen and oxygen are achieved.

The use of ethanol as a mobile phase allowed good chromatographic separation with excellent evaluation by Green Analytical Chemistry metrics.

Investigation of polybrominated diphenyl ethers (PBDE) levels in Paranoá Lake sediments revealed higher concentrations attributed to effluent discharges from wastewater treatment plants and storm drainage water systems.

Efficient and reusable adsorbents with pyrochlore structure can be synthesized by a simple route and applied to remove pollutants from aqueous media.

A multiresidue and multiclass method was developed for the determination of current-use pesticides (CUPs) in water samples using solid phase extraction (SPE) with polymeric sorbent and ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS).

This review aims to provide an overview of the methods for determining pesticide residues in exotic fruits, focusing on the strategies employed by these methods and the occurrence of pesticide residues.

Teaching chemistry as a tool for sustainability based on discussions of environmental chemistry in the classroom: challenges and achievements in 27 years of disseminating research in chemical education through the journal Quimica Nova na Escola (QNESc).

This work will focus on Sustainable Development Goals 3 and 4, respectively, which will be achieved if citizens have a sustainable education. This plays an important role in having a healthy life.

Qualitative research employing Bardin's content analysis methodology: this study delves into the approach of Sustainability and Sustainable Development Goals (SDGs) in textbooks of Natural Science area, specifically within Chemistry context.

(S)-Pyroglutamic acid solvent-free synthesis in undergraduate experimental classes to reinforce sustainable preparation and understanding of properties of chiral compounds in the solid state.

Biomass is a promising raw material for energy generation and is relevant to be used in chemistry education by enabling the discussion about sustainable development goals (SDGs). For higher education, it is recommended that planning and execution be based on problematized experimental activity (PEA).

Green chemistry principles are introduced to undergraduate students as an experimental class applying mechanochemistry to prepare both 2-bromoacetophenone and 2-phenylimidazo[1,2-α]pyridine through manual grinding and vortex mixing.

Sustainability, sustainable development, sustainable chemistry and green chemistry are very close and closely interconnected topics, but they present very different concepts.
