About 3 billion new tires are produced each year and about 800 million become waste annually. Global dependence upon from natural rubber petroleum-based compounds represents a persistent complex environmental problem with only partial often-times, ineffective solutions. Tire emissions may be in the form of whole tires, tire particles, chemical compounds, which is transported through various atmospheric, terrestrial, aquatic routes built environments. Production use generates multiple heavy metals, plastics, PAH's, other that can toxic alone or as cocktails. Used require storage space, energy intensive to recycle, generally have few post-wear uses not also potential sources pollutants (e.g., crumb rubber, pavements, burning). particles emitted during major component microplastics urban runoff source unique highly potent substances. Thus, represent ubiquitous pollutant requires comprehensive examination develop effective management remediation. We approach issue pollution holistically by examining life cycle across production, emissions, recycling, disposal. In this paper, we synthesize recent research data human health risks associated use, disposal discuss gaps our knowledge fate transport, well toxicology leachates. examine remediation approaches for addressing exposure tires. consider three levels: their state, particulates, mixture Finally, information understanding outline key questions improve ability manage remediate pollution.

Acute Cardiorespiratory Effects of 6PPD-Quinone on Juvenile Rainbow Trout (Oncorhynchus mykiss) and Arctic Char (Salvelinus alpinus)

Aquatic Toxicology, Год журнала: 2025, Номер 280, С. 107288 - 107288

N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-quinone) is an environmental transformation product of the widely used rubber tire antioxidant, 6PPD. Found in stormwater runoff, 6PPD-quinone has been reported to cause acute lethality at ≤1 μg/L salmonids like coho salmon, rainbow trout, and brook trout. Conversely, other species such as Arctic char brown trout are insensitive, even when exposed significantly greater concentrations (3.8-50 μg/L). Sensitive exhibit symptoms gasping, spiraling, increased ventilation, loss equilibrium, suggesting a possible impact on cardiorespiratory physiology. This study investigated sublethal toxicities, focusing cardiovascular metabolic effects two varying sensitivity: sensitive species, (Oncorhynchus mykiss) tolerant (Salvelinus alpinus). Fish were measured 0.59 or 7.15 6PPD-quinone, respectively, respirometry chambers for 48 h assess temporal changes resting oxygen consumption compared unexposed controls. Following exposure, cardiac ultrasound electrocardiography characterized function vivo, while blood gas analysis examined composition changes. In both observed. only, decrease end systolic volume increase passive ventricular filling, output, PR interval length observed, indicating stimulation. Cardiorespiratory observed following exposure might partly be driven by significant methemoglobin, resulting impaired ability oxygenate tissues. first examine system salmonid fishes provides information invaluable better understanding mechanism toxicity.

ECOTIRE: A New Concept of a Smart and Sustainable Tire Based on a Removable Tread

Applied Sciences, Год журнала: 2025, Номер 15(7), С. 3675 - 3675

Опубликована: Март 27, 2025

This paper introduces a new concept of smart and sustainable tire based on removable tread band: ECOTIRE. Current tires, though crucial for road information vehicle control, such as braking, traction, turning, remain disconnected from Advanced Driver Assistance Systems (ADAS). Additionally, their production, use, recycling pose significant environmental challenges, requiring materials lifecycle improvements. The ECOTIRE makes it possible to separate the part subject wear apply with reduced impact. At same time, service life casing is extended, facilitating introduction sensors that improve safety. study explores purely mechanical connection between tread, demonstrating feasibility this innovative structure while eliminating need rubber matrix-based proper bond two components. Experimental tests using sample simulate tire–road contact patch validate effectiveness link under varying normal loads. Grip test results, measuring longitudinal lateral forces, show promising performance. advancement in technology marks first step toward sustainability, performance, integration, ultimately reducing

Few studies exist that focus on contaminants of emerging concern (CECs) in transitional and coastal waterbodies. This study presents chemical profiling two protected marine harbours the South coast UK sampled 2022. Across 21 sites, 105 unique compounds were detected (0.05 ng L-1 --1798 L-1, median: 11 L-1) water samples biota, including 67 pharmaceuticals, 29 pesticides nine recreational drugs. There significant differences between campaigns with increased numbers concentrations coincided rainfall combined sewer overflow (CSO) discharges. The comparison CSO discharges revealed they an important source for loading specific chemicals increasing some cases by three-orders magnitude. High relative risks estimated sites during recorded five risk quotients (RQs) ranging from 1.1 up to 9.3, highest neonicotinoid, imidacloprid. To understand exposure six species; one macroalgae (Fucus vesiculosus) fauna (Hediste diversicolor, Patella vulgate, Crassostrea gigas, Carcinus maenas, Echinogammarus marinus) analysed (n = 5/species) at a CSO-impacted site. Between eight 18 Fucus vesiculosus (seaweed) showing accumulation mean cumulative burdens reaching 343 ± 71 g-1. Surface contamination did not correlate body burdens. Overall, work highlights complexity space present waterbody dynamic patterns are further influenced tide, salinity. CSOs demonstrated but compound role CEC input pulsing into receiving waters.
