“…RDS PSD grading envelopes are shaped by both natural phenomena and anthropogenic activities. Natural phenomena are primarily associated with atmospheric deposition (Murphy et al 2014). Anthropogenic activities are local in nature and are associated with erosion of soil and roadside verges, vegetation detritus from surrounding land use and vehicular motion and related activities.…”

This study investigates the contribution of road deposited sediment (RDS) to clogging and the operational lifecycle of highway filter drains (HFDs). RDS samples were collected from nine Scottish trunk roads and fractionated into grain size classes to determine their particle size distributions (PSDs). Results show that RDS PSDs, and the percentage of each grain size fraction, are highly variable. However, despite being collected from different trunk roads, PSD trends are similar, with individual RDS particles ranging in size from <63 μm to >10,000 μm. Medium sand, coarse sand, fine gravel and medium gravel make up 84.1% of the total particle mass concentration, with particles >1,000 μm mostly mineral or asphalt. The study also reveals that the dynamic nature of a trunk road catchment dictates that grading envelopes are essentially instantaneous values. These findings indicate that large particles from the road surface contribute to clogging and have the potential to reduce the operational lifecycle of HFDs. The study also demonstrated that assuming a single RDS PSD profile for filter drain asset management purposes is unlikely to be representative of a trunk road catchment profile.

“…The pollution of the surfaces and the type of land use around the urban channels are considered as some of the in uential factors in the contamination of output ecosystems as result of urban runoff pollution [21]. The sediments of urban runoff are originated from both direct sources (vehicles transportation, including transportation of vehicles, tires ,and car brake pads, exhaust output, oil and oil spills, breakdown of surface materials (repairs, destruction, paint), and soil erosion) [11,[22][23][24], and or indirect sources (such as atmospheric deposition) [25].…”

Heavy metals contamination is vitally crucial issue for human health and natural ecosystems worldwide. The sediments are extremely responsible for accumulation, transfer, and the fate of them into the receiving ecosystems. In this research, the heavy metals pollution status of surface sediments, possible pollution source as well as the correlation between heavy metals with total organic carbons (TOC%) and particle size distribution were evaluated. In this sense, 30 surface sediment samples of three urban channels from three sub-catchments across Tehran megacity was collected, followed by the concentration of key elements strontium (Sr), lead (Pb), cadmium (Cd), nickel (Ni), and copper (Cu) was quantified by applying Inductively coupled plasma-optical emission spectrometry(ICP-OES). According to factor analysis(FA), the possible accumulation reason of (Pb) and (Sr) is as different as Copper, Nickle, and Cadmium elements. The Pearson test and multiple linear regression assigned that the TOC% is the leading reason of Strontium accumulation in surface sediments (r = 0.901). Ultimately, the vehicle transportation and land use type around the urban channels were recognized as the feasible principal origin of heavy metals contamination.

“…Falling raindrops catch solid particles from the atmospheric air, as well as liquid or gaseous substances, which to some extent shape the quality of precipitation. In particular, dust, smoke or chemical substances from industrial or agricultural areas may deteriorate rainwater quality [20,21], which may also result in the appearance of new pollutants in the aquatic environment (i.e., the so-called emerging pollutants (EPs)) that have not been monitored before and for which there are no regulatory standards, such as pharmaceuticals and personal hygiene products, veterinary products, endocrine disruptors and microplastics [22][23][24][25]. Depending on the duration, intensity and time interval between rainfall and the presence of other natural and anthropogenic factors, rainwater quality is highly variable.…”

Detection and Removal of Priority Substances and Emerging Pollutants from Stormwater: Case Study of the Kołobrzeska Collector, Gdańsk, Poland

Progressive urban development affects environmental balance and disrupts the hydrologic cycle, in which rainfall plays a significant role. Since rainwater is considered a valuable resource of the environment, many technical solutions are implemented that enable effective rainwater management. On the other hand, stormwater runoff from urban areas contains numerous (also toxic) substances, and therefore should be properly treated. In this study, a multistage constructed wetland (MCW) pilot installation was used to remove selected groups of priority substances and emerging pollutants from rainwater discharged from the urbanized catchment of the Kołobrzeska stormwater collector in Gdańsk, Poland. The obtained results show that rainwater runoff was characterized by a variable concentrations of heavy metals (Zn, Cd, Cu, Ni, Pb, Hg), polycyclic aromatic hydrocarbons (benzo(a)pyrene, benzo(b)fluoranthene, phenanthrene, fluoranthene and pyrene) and microplastics. Depending on the hydraulic load of the bed, the reduction efficiency for heavy metals ranged from 26.19 to 100%, and for microplastics from 77.16 to 100%, whereas for polycyclic aromatic hydrocarbons it was consistently high, and equaled 100%.
