“…As mentioned above, heavy metal contaminants in water produce a huge risk for irrigation due to their toxicity, nonbiodegradation, and potential for mass accumulation (Zuo et al, 2012;Zhang et al, 2012;Singh et al, 2011;Nie et al, 2008;Fuerhacker et al, 2011). Table 3 also shows the limits for irrigation water and reclaimed water in urban areas in China.…”

“…Among many other pollutants, heavy metals are highly hazardous due to their toxicity, non-biodegradation, and mass accumulation (Zuo et al, 2012;Zhang et al, 2012;Singh et al, 2011;Nie et al, 2008;Fuerhacker et al, 2011). Heavy metal accumulation in receiving waters can have a significant impact on aquatic organisms by absorption and bioaccumulation, potentially contaminating the local marine ecosystem (Vardanyan et al, 2006).…”

Porous asphalt pavements have been used as an effective technique to overcome road runoff challenges, and to improve efficiency of rainwater utilisation in urban areas. Using porous asphalt pavements with reservoir storage and harvesting facilities is an important consideration for the future. This study monitored changes in water quality indicators, such as pH, conductivity, and concentrations of lead and zinc, for water stored in porous asphalt pavement models with basalt-, limestone-and 'basalt+limestone'-filled reservoir structures. The research discusses findings over a 696-h storage period following artificial rainfall. Total lead and zinc concentrations were remarkably reduced throughout the initial flush, showing, on average, reductions of 90% and 80.5%, respectively. This pattern was consistent throughout the storage period, producing average reductions in lead and zinc of 99.98% and 79%, respectively, over 696 h. Conductivity and pH levels increased in all pavement models after the 696-h storage. The results obtained confirmed the potential of using porous asphalt pavements with reservoir structures to remove heavy metals from road runoff. This can be applied to future research on the removal mechanisms of porous asphalt pavements in relation to heavy metals in road runoff.

“…Key: TSS = total suspended solids; DIN = dissolved inorganic nitrogen; TPH = total petroleum hydrocarbons Fuerhacker et al (2011) have assessed a filtration system consisting of three filter chambers filled with layers of reactive media (composite, zeolite, vermiculite and granular activated carbon) and preceded by sedimentation and oil separator tanks for the treatment of car park runoff. The monitored pollutants and their mean removal efficiencies were TSS (85%), mineral oil (93%), TOC (52%), NH 4 -N (71%), total Cu (75%), total Zn (73%) and Σ16 PAH (83%).…”

Traffic emissions contribute significantly to the build-up of diffuse pollution loads on urban surfaces with their subsequent mobilisation and direct discharge posing problems for receiving water quality. This review focuses on the impact and mitigation of solids, metals, nutrients and organic pollutants in the runoff deriving from car parks. Variabilities in the discharged pollutant levels and in the potentials for pollutant mitigation complicate an impact assessment of car park runoff. The different available stormwater best management practices and proprietary devices are reported to be capable of reductions of between 20% and almost 100% for both suspended solids and a range of metals. This review contributes to prioritising the treatment options which can achieve the appropriate pollutant reductions whilst conforming to the site requirements of a typical car park. By applying different treatment scenarios to the runoff from a hypothetical car park, it is shown that optimal performance, in terms of ecological benefits for the receiving water, can be achieved using a treatment train incorporating permeable paving and bioretention systems. The review identifies existing research gaps and emphasises the pertinent management practices as well as design issues which are relevant to the mitigation of car park pollution.

“…light expanded clay aggregates (LECA), expanded shale, expanded slate and exfoliated vermiculite) [19,20,[25][26][27][28]. Among thermally processed clay materials, LECA and exfoliated vermiculite have been increasingly used over the latest years for water and wastewater treatment, performing several possible roles, such as filters or as support matrix in constructed wetlands systems [19,[29][30][31][32][33][34][35][36][37][38]. Both materials have exhibited good adsorbent qualities for the removal of several organic pollutants [25,28,39,40].…”
