Environmental monitoring data for tire road wear particles are vastly limited compared to those other microplastics, primarily due analytical challenges with quantification. Recently, two ISO technical specifications have been released using pyrolysis GC-MS However, these methods major assumptions, including that the content of natural and synthetic rubber in tread is constant across formulations products chosen selective. This study analyzed a wide range commercially available tires from...
Tire and road wear particles may constitute the largest source of microplastic into environment. Quantification these are associated with large uncertainties which in part due to inadequate analytical methods. New methodology is presented this work improve analysis tire using pyrolysis gas chromatography mass spectrometry. Pyrolysis spectrometry styrene butadiene styrene, a component polymer-modified bitumen used on asphalt, produces products identical those rubber rubber, tires. The...
Road pollution is one of the major sources microplastic particles to environment. The distribution tire, polymer-modified bitumen (PMB) and tire road wear (TRWP) in different tunnel compartments were explored: surface, gully-pots wash water. A new method for calculating TRWP using Monte Carlo simulation presented. highest concentrations on surface side bank (tire:13.4 ± 5.67;PMB:9.39 3.96; TRWP:22.9 8.19 mg/m2), comparable previous studies, at outlet (tire:7.72 11.2; PMB:5.40 7.84; TRWP:11.2...
Traffic pollution has been linked to high levels of metals and organic contaminants in road-side soils, largely due abrasion tires, brake pads the road surface. Although several studies have demonstrated correlations between different pollutants various traffic variables, they mainly focused on roads with medium density (>30,000 vehicles per day). In this study we investigating tire wear particles road-related (zinc, copper, lead, chromium, nickel, metalloid arsenic) soils low rural areas...
Abstract Constructed stormwater ponds mitigate runoff volumes and pollution, provide other ecosystem services, such as supporting biodiversity, but these services attracted relatively less attention. The impacts of the pollution levels in water column sediments, physical characteristics ponds, presence amphibians on macroinvertebrate community composition biodiversity were explored twelve Norway. Also, similarities between macroinvertebrate, zooplankton plant communities explored. Most taxa...
Climate change and its effects, for instance drought, drive the search alternative water sources. One of these sources is rainwater, especially runoff from various roof surfaces in cities. In turn, use city production food as part hydroponic aquaponic systems requires knowledge possible pollutants their varied concentrations. this article, concentrations benzene, toluene, ethylbenzene, xylene (BTEX) rainwater collected cities stored types tanks (open closed) are analysed. Tests were carried...
Abstract Road runoff carries a mixture of contaminants that threatens the quality natural water bodies and health aquatic organisms. The use sedimentation ponds is nature-based solution for treatment road runoff. This study assessed concentration polycyclic aromatic hydrocarbons (PAHs) their alkylated homologues in sediment from seven highway three urban ponds. In addition, explored bioaccumulation PAHs dragonfly nymphs (Anisoptera). Finally, biota-sediment accumulation factors (BSAFs) were...
Snowmelt, surface runoff, or stormwater releases in urban environments can result significant discharges of particulate matter-bound polycyclic aromatic hydrocarbons (PAHs) into aquatic environments. Recently, more-specific activities such as road-tunnel washing have been identified contributing to contaminant load waters. However, knowledge PAH accessibility matter (PM) origin that may ultimately be released waters is limited. In the present study, we evaluated PAHs associated with seven...
The use of stormwater ponds along the highways is shown to be an effective alternative conventional systems, which are usually sewers. These have potential combine their primary function pollution and peak flow control with promotion biodiversity. present study focuses on comparing natural highway in terms environmental conditions biodiversity macroinvertebrate communities. Twelve nineteen (located within or vicinity cultivated landscape) were explored for number taxa, community composition,...
Abstract Nitrite and nitrate are used as additives in the food industry to provide color taste control undesirable gas flavor production by anaerobic bacteria virtue of their antimicrobial properties. The analytical method that has been widely determine nitrite involves use toxic cadmium. In response a request from Nordic Committee on Food Analysis, study was performed obtain an alternative chromatographic residual meat products. done 3 stages: (1) comparative evaluation performance liquid...
Stormwater ponds are used to compensate for the adverse effects that road runoff might have on natural environment. Depending their design and placement, stormwater can act as both refugia traps local biodiversity. To evaluate impact of biodiversity, it is critical use effective precise methods identification life associated with water body. DNA metabarcoding has recently become a promising tool assessment freshwater biodiversity.Using morphology metabarcoding, we analyze species richness...
Road tunnels play a crucial role in modern road networks, both urban and non-urban areas, necessitate frequent cleaning washing due to the harsh tunnel environment. As result, are considered hot spots for emission of road-related pollutants into In this study, we conducted extensive measurements tire wear particles (TWPs) 18 tire-derived chemicals (TDCs) during process, throughout 21-day treatment period rectangular sedimentation basin concrete, discharge treated wash water. Our key findings...
Abstract Nowadays, stormwater sedimentation ponds are popular in management because of their ability to mitigate flooding and treat polluted runoff from e.g. roads. In addition, they may provide other ecosystem services such as biodiversity. These man-made habitats will inevitably be the organisms living therein negatively affected by chemical cocktail present both water sediment compartments. The study explored DNA damage dragonfly nymphs (Odonata, Anisoptera) highway comparison with...
