With the digital revolution across world, including in low- and middle-income countries (LMICs) like Bangladesh, global burden of electronic waste (e-waste) is increasing. Consequently, environmental human health implications informal e-waste recycling practices LMICs are becoming a cause for concern. Here we report indoor dust air contamination from derived heavy metals shops Dhaka, capital Bangladesh. Representative Pb, Cu, Ni, Cr, Mn were measured samples collected three different located...
The adsorption of foulants on photocatalytic nanoparticles can suppress their reactivity in water treatment applications by scavenging reactive species at the photocatalyst surface, screening light, or competing for surface sites. These inhibitory effects are commonly modeled using Langmuir–Hinshelwood model, assuming that adsorbed layer compositions follow Langmuirian (equilibrium) competitive adsorption. However, this assumption has not been evaluated complex mixtures foulants. This study...
Nanoplastics are of rapidly emerging concern as ubiquitous environmental pollutants. However, fate and transport assessments currently hindered by a need for new analytical methods that can selectively quantify nanoplastics in matrices. This study presents the first proof principle to hyphenate asymmetric flow field-flow fractionation (AF4) with total organic carbon (TOC) detection analysis, evaluated on mixtures multimodal polystyrene presence dissolved matter clay colloids. The AF4-TOC...
