“…Pharmaceuticals have emerged as an important group of contaminants of emerging concern (CECs) and merit considerable attention owing to their potentially undesirable ecological effects. 1,2 Large quantities of pharmaceuticals are consumed globally, excreted via urine and feces into wastewater, enter wastewater treatment plants (WWTPs), and are then discharged via WWTP effluents into receiving rivers. 3,4 Unused pharmaceuticals can also pollute the environment.…”

Pharmaceuticals have been detected at high concentrations in municipal solid waste (MSW) landfill leachates, which are recognized as an underestimated source of pharmaceutical residues in the environment. However, limited efforts have been made to characterize pharmaceuticals in MSW landfill refuse, which is also of significant concern given the potential long-term environmental impact. Herein, we excavated landfill refuse from six cells with landfill ages of 7−27 years in the largest MSW landfill in Shanghai (in each cell, landfill refuse was collected from different depths of 2−8 m) and analyzed samples for the presence of 55 pharmaceuticals, including antibiotics and non-antibiotics. The results reveal the presence of 42 pharmaceuticals in landfill refuse, with median concentrations ranging from 0.30 to 116 μg/kg. Antibiotic and non-antibiotic pharmaceuticals exhibited diverse concentration trends with age, related to changes in policy intervention and consumption over time. Different concentration variations of individual pharmaceuticals were observed in refuse samples excavated at different depths and positively correlated to their sorption ability. The mass of pharmaceuticals in the investigated landfill was estimated from the obtained concentrations to be 80−220 tons with 95% probability, based on Monte Carlo analysis. To the best of our knowledge, this study provides the first estimate of pharmaceutical mass in an MSW landfill. The results will be helpful for understanding the potential long-term environmental impact of pharmaceuticals in landfills.

“…20 Currently a lot of focus is given to the development of adsorbents from waste materials by suitable modications, adhering to the "waste to wealth" principle. [21][22][23] Biomass has been identied as a green resource for the synthesis of char based adsorbents for decontamination of water from phosphates, 24 organic pollutants 25 and many heavy metal ions. 26 Biochar is produced by the thermal degradation of biomass under oxygen limited conditions.…”

“…Treatment and recycling of wastewater and electronic waste (e-waste) have become increasingly necessary due to the presence of precious, critical, and strategic metals as well as the environmental impact of metal recovery [1][2][3]. e-waste is highly heterogeneous and includes a wide range of materials, such as metals, plastics, and ceramics, which are nonbiodegradable pollutants.…”

Through the electrodeposition technique, toxic metals in wastewater can be removed and deposited on a chosen substrate with excellent selectivity. In this work, we use this technique to extract lead cations from simulated wastewater by using fluorine-doped tin oxide (FTO) substrate at various temperatures. In situ tracking of lead nucleation at advanced stages has been achieved by chronoamperometry. According to the experimental results, the theoretical models developed to study the kinetic growth of lead deposits in 2D and 3D are in good agreement. Nucleation rate and growth rate constants, for example, were found to be strongly influenced by temperature. Cottrell’s equation is used to calculate the diffusion coefficient. X-ray diffraction, scanning electron microscopy, and energy-dispersiveX-ray techniques were used to investigate and characterize the lead deposits. The reported results could provide insight into the optimization of electrodeposition processes for heavy metal recovery from wastewater and electronic wastes.
