“…Water as a source of life is a scarce resource in most countries (Hofste, Reig and Schleifer, 2019). Although one needs to acknowledge that some fibres are more environmentally friendly, and strides have been made in the fashion industry to reduce the negative environmental impact with some interventions (Nasir, Wee, Aris, Abdullah and Ismail, 2022), we agree with Taljaard and Sonnenberg (2019) who point out that the 'tale' of the environment and fashion consumption has always been a contentious one. In the bigger scheme of things, it is also about the volume of fashion that is consumed, and the manufacturing will not stop if the demand from the retailers and ultimately the consumers is constant!…”

The fashion industry has long been in a battle to improve its sustainability, as well as its environmental protection efforts. In thisconceptual paper, we unpack the different stories of sustainability and environmental challenges in this specific industry – which is very much driven by fast fashion. We contrast developing (South Africa) and developed (Sweden) markets’ approaches to fashion sustainability, to uncover and understand broad overlapping dimensions of sustainability, and differences. The aim of this paper is to stimulate thinking and conversations about sustainable practices in developing nations as well as in developed nations. The review of the stories and the contexts presented suggests the need to shift the focus to the developing market’s consumer, and concludeswith the proposal of including a fifth principle of sustainability: Reframing fashion.

“…Recently, Wang et al 122 reported the excellent adsorption capacity of magnetic nanoparticles-attached fluorographenebased sorbent for PFOA and PFAS removal, surpassing activated carbon, with high removal efficiencies of 92-95% for PFOA and 94-97% for PFOS, effectively reducing their concentrations in the environment (~5 μg/L) to below 50 ng/L. Nasir et al 123 proposed the use of agro-biomass biochar as a natural adsorbent for the removal of emerging organic contaminants, including PFAS. Moreover, the utilization of advanced materials such as metalorganic frameworks (MOFs) for the remediation of PFAScontaminated water has gained attention.…”

Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), known as the most detected per- and polyfluoroalkyl substances (PFAS) in various environmental compartments, have been associated with plastic pollution and endocrine dysfunction. Over the past 180 years (1839–2019), numerous emerging contaminants have been identified, with PFOA and PFOS receiving considerable attention based on scientific evidence and publications. Between 2018 and 2019, PFOA and PFOS experienced a relatively high increase rate of 18.8% and 13.6%, respectively. While developed countries have made progress in establishing stringent guidelines, developing and underdeveloped countries often lack regulations and mechanisms to address emerging PFAS. Furthermore, advancements in PFAS removal technologies are needed to improve their efficacy and feasibility. The establishment of regulatory compliances, along with exposure assessment and risk characterization, is essential for providing precautionary advice on water source protection, water supply security, health risks, treatment efficiency, and contamination forecasting. However, a more comprehensive approach and database for evaluating exposure and risks are still imperative to effectively combat PFAS contamination in drinking water. Therefore, this review aims to enhance environmental monitoring and management practices in response to the global crisis of PFAS contamination. The analysis of Needs, Approaches, Benefits, and Challenges (NABC) is grounded in the current trends of PFAS in the environment and human exposure through drinking water.

“…With the increase in the pyrolysis temperature, the adsorption quantities increased and the maximum adsorption amounts (Q m ) of the biochars prepared at 700 • C were 2.31-4.72 times that of the biochars prepared at 500 • C. This may have been due to the microporous nature inside the biochar, and that the specific surface area increased at higher pyrolysis temperatures [28]. In addition, the value of n decreased as the pyrolysis temperature increased, and the nonlinearity of adsorption isotherms gradually increased, indicating that more inhomogeneous "vitreous", "hard carbon", or highly concentrated adsorption potentials were formed on the surface of biochar, and the adsorption energy was higher for these adsorption sites [29,30].…”

The high porosity of medium-coarse sand (MCS) layers in groundwater recharge areas presents a high environmental risk. Sulfamethoxazole (SMX) and trimethoprim (TMP) are two common sulfonamide antibiotics in surface water that have a high propensity to migrate into groundwater. In this study, four biochars were prepared and biochar-amended soil aquifer treatment (SAT) columns were constructed to remove SMX and TMP. Batch experiments demonstrated that the sorption isotherms conformed to the Freundlich model. The maximum adsorptions of biochars prepared at 700 °C were 54.73 and 67.62 mg/g for SMX and 59.3 and 73.38 mg/g for TMP. Electrostatic interaction may be one of the primary mechanisms of adsorption. The column experiments showed that the SMX and TMP removal rate of the biochar-amended SAT was as high as 96%, while that of the MCS SAT was less than 5%. The addition of biochar greatly improved the retention capacity of the pollutants in the MCS layer in the groundwater recharge area and effectively reduced environmental risk.
