Long-term exposure to urban dust containing potentially toxic elements (PTEs) poses detrimental impacts on human health. However, studies estimating health risks in dusts from a global perspective are scarce. We evaluated data for twelve PTEs across 59 countries 463 published articles, including their concentrations, input sources, and probabilistic found that 34.1 60.3% of those investigated have been heavily contaminated with As Cd, respectively. The was significantly correlated economic structure due emissions industrial activities traffic being the major sources. Based Monte Carlo simulation, we mean hazard index below safe threshold (1.0) could still cause non-negligible Arsenic Cr were threatening health, relatively high risk levels observed cities China, Korea, Chile, Malaysia, Australia. Importantly, our analysis suggested threaten approximately 92 million adults 280 children worldwide. Overall, study provides important foundational understanding guidance policy decision-making reduce potential associated PTE promote sustainable development economies.

Liquid crystal monomers in ventilation and air conditioning dust: Indoor characteristics, sources analysis and toxicity assessment

Environment International, Journal Year: 2023, Volume and Issue: 180, P. 108212 - 108212

Indoor dust contaminated with liquid crystal monomers (LCMs) released from various commercial display (LCD) screens may pose environmental health risks to humans. This study aimed investigate the occurrence of 64 LCMs in ventilation and air conditioning filters (VACF) dust, characterize their composition profiles, potential sources, associations indoor characteristics, assess vitro toxicity using human lung bronchial epithelial cells (BEAS-2B). A total 31 concentrations (ΣLCMs) ranging 43.7 ng/g 448 were detected collected VACF dust. Additional analysis revealed interactions between conditions exposure associated The service area working time system, number LCD positively correlated fluorinated ΣLCMs (r = 0.355 ∼ 0.511, p < 0.05), while non-fluorinated not found (p > suggesting different behavior fates environment.

Release Behavior of Liquid Crystal Monomers from Waste Smartphone Screens: Occurrence, Distribution, and Mechanistic Modeling

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(28), P. 10319 - 10330

Published: June 27, 2023

Liquid crystal display (LCD) screens can release many organic pollutants into the indoor environment, including liquid monomers (LCMs), which have been proposed as a novel class of emerging pollutants. Knowing pathways and mechanisms LCMs from various components LCD is important to accurately assess LCM reveal their environmental transport behavior fate in ambient environment. A total 47, 43, 33 out 64 target were detected three disassembled parts waste smartphone screens, layer (LL), light guide plate (LGP), screen protector (SP), respectively. Correlation analysis confirmed LL was source LGP SP. The emission factors screen, SP, estimated 2.38 × 10–3, 1.36 1.02 mechanism model developed describe behaviors where characteristics parameters released LCMs, average mass proportion (AP), predicted subcooled vapor pressures (PL), octanol–air partitioning coefficients (Koa), involving coexistence absorption adsorption mechanisms, could control diffusion-partitioning. reach diffusion-partition equilibrium more quickly than those indicating that be mainly governed through SP diffusions.
