“…Water pollution with heavy metals is a worldwide concern. High levels of metals are toxic to both humans and the living organisms in aquatic ecosystems [ 1 , 2 ]. Metals come from either natural sources, like soil erosion and volcanic activities, or anthropogenic causes, as environmental problems derived from mining operations like acid mine drainage (AMD) [ 3 , 4 ].…”

Adsorption technologies are a focus of interest for the removal of pollutants in water treatment systems. These removal methods offer several design, operation and efficiency advantages over other wastewater remediation technologies. Particularly, graphene oxide (GO) has attracted great attention due to its high surface area and its effectiveness in removing heavy metals. In this work, we study the functionalization of GO with zinc oxide nanoparticles (ZnO) to improve the removal capacity of aluminum (Al) and copper (Cu) in acidic waters. Experiments were performed at different pH conditions (with and without pH adjustment). In both cases, decorated GO (GO/ZnO) nanocomposites showed an improvement in the removal capacity compared with non-functionalized GO, even when the pH of zero charge (pHPZC) was higher for GO/ZnO (5.57) than for GO (3.98). In adsorption experiments without pH adjustment, the maximum removal capacities for Al and Cu were 29.1 mg/g and 45.5 mg/g, respectively. The maximum removal percentages of the studied cations (Al and Cu) were higher than 88%. Further, under more acidic conditions (pH 4), the maximum sorption capacities using GO/ZnO as adsorbent were 19.9 mg/g and 33.5 mg/g for Al and Cu, respectively. Moreover, the removal percentages reach 95.6% for Al and 92.9% for Cu. This shows that decoration with ZnO nanoparticles is a good option for improving the sorption capacity of GO for Cu removal and to a lesser extent for Al, even when the pH was not favorable in terms of electrostatic affinity for cations. These findings contribute to a better understanding of the potential and effectiveness of GO functionalization with ZnO nanoparticles to treat acidic waters contaminated with heavy metals and its applicability for wastewater remediation.

“…The study site is a no‐till pasture field located in the Sand Mountain region of North Alabama (34°17′02.6″N, 85°57′51.8″W), a major broiler production area in the state (Lamba et al., 2019). This region is part of the Cumberland Plateau section of the Appalachian Plateau physiographic province (Sen et al., 2008) (Figure 1).…”

Repeated broiler litter application on agricultural lands can cause nutrient enrichment of subsurface effluent, especially with the existence of preferential flow through soil macropores. Previous studies quantifying soil macropores have not attempted to establish a connection of soil macropore characteristics with the subsurface nutrient (nitrogen [N] and phosphorus [P]) losses, across different topographical locations in the field. This study investigated the effect of broiler litter application and preferential flow on subsurface nutrient transport (N and P) at different topographical positions (upslope, midslope, and downslope) in a no‐till pasture field located in Alabama, USA. Twelve intact soil columns (150 mm id and 500 mm length) were used, and the nutrient leaching measurements from laboratory experiments were linked to soil macropore characteristics quantified using X‐ray computed tomography image analysis and solute transport modeling. Treatments included surface broadcast broiler litter (5 Mg ha−1, on dry basis) and unamended control. Leachates were analyzed for dissolved reactive P (DRP), total P (TP), and nitrate + nitrite‐N (NO3− + NO2−–N). The bromide breakthrough curves provided evidence of preferential flow in all columns. Litter application significantly increased leachate P concentrations, and average TP and DRP concentrations were significantly higher in the leachate from upslope columns compared to those at downslope location. The NO3−–N concentrations in leachate exceeded the US EPA drinking water standard of 10 mg L−1 in all the treatment columns. The highest flow‐weighted mean concentrations of TP and DRP, at 2.7 and 2.5 mg L−1, respectively, were recorded in the upslope columns. Soil physicochemical properties and nutrient leaching losses varied substantially across topographical positions, indicating a need for variable litter application rates to reduce P build‐up and subsequent leaching in vulnerable locations within the field. The relevance of the effect of topographic position on nutrient leaching found in this study should be further tested by investigating a wider range of slopes and soil types in pastures.

“…Metal concentrations in manure often reflect the metal concentrations in chicken feed. Therefore, the high metal content of soils treated with broiler litter can enhance the flow of metals to surface waters through runoff [11]. The levels of Cadmium (Cd) and Lead (Pb) in chicken feed in Asia, North, and South America are alarmingly high, at 782.8 mg Cd/kg and 722.4 mg Pb/kg, respectively.…”

This study addresses the imperative of sustainable broiler waste management in Thailand, a significant global producer and exporter of broiler meat. Utilizing an Analytic Hierarchy Process (AHP) analysis, it systematically evaluates three waste management strategies – direct land application, composting, and gasification – across environmental, economic, technical, and social criteria with 15 sub-criteria. Climate change is identified as the top priority sub-criterion, followed closely by water use. Gasification emerges as the most preferred option with 52.6% preference, outperforming composting (24.8%) and direct land application (22.6%). A comprehensive analysis reveals gasification's superior environmental and social performance, while direct land application demonstrates economic efficacy. Composting exhibits a well-rounded performance across all criteria. Pioneering the AHP model in broiler waste management, this study offers policymakers crucial insights for formulating sustainable long-term policies to address this pressing issue.
