“…Particles size distributions reported on a volume, number or mass basis all identify the predominance of finer particles sizes (often finer than 10 µm) in the runoff from heavily used roads with a tendency to a slightly coarser distribution being observed for car parks and residential roads. The increased surface area associated with finer particles, combined with a higher cation exchange capacity, provides them with a greater affinity for pollutants, such as metals (Dong and Lee, 2009;Liebens, 2001;Ujevic et al, 2000). Hence, the finer fractions contribute more pollutants per unit mass and following wash-off will remain in suspension longer providing the opportunity to travel further (Herngren et al, 2006;McKenzie et al, 2008).…”

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.

“…Sediments could be polluted by various means other than natural sources, such as via polluted river water, where the river could be polluted by the waste water outflows, airborne inputs, rainfall, dust precipitation, industrial sludge and transport activities [1]. Determination of the concentration of heavy metals in the sediment is important for assessing the nature and extent to which the aquatic environment is polluted.…”

ABSTRACT. In the present study, laser-induced breakdown spectroscopy (LIBS) has been applied for the determination of levels of Cr, Mn and Fe in sediment samples and the results have been compared with that of flame-atomic absorption spectroscopy (F-AAS). Fourteen sediment samples were collected from Tinishu Akaki River (TAR), Addis Ababa, Ethiopia. Pellets of 24 mm in diameter and 3−5 mm in thickness were prepared using a manual hydraulic press under a pressure of 8000 psi by mixing finely ground sediment samples with boric acid. The concentrations of Cr, Mn and Fe were successfully determined by Q-switched Nd:YAG laser at 1064 nm. Quantification of these metals was conducted against certified reference materials of sediments and soils. The LIBS results for the elements varied from 0.060-0.707 mg/g for Cr, 0.895-3.64 mg/g for Mn and 26.9-71.8 mg/g for Fe. The F-AAS results varied from 0.061-1.37 mg/g for Cr, 1.24-4.46 mg/g for Mn and 49.0-83.3 mg/g for Fe. TAR was found to be heavily polluted with Cr.

“…The nature of the substrate is also important in studies of trace metals. Finer sediments usually contain higher concentrations of contaminants than coarser sediments (Ujevic, Odzak, & Baric, 2000). In this context clams like A. tuberculosa (Gulf of Nicoya and Golfito) and P. arctata (Moín Bay) are found in fine grained sediments, while T. affinis lives in an extensive coarse sand flat at the mouth of the Lagarto River, which drains mostly grass lands for cattle raising.…”

Abstract:The input of contaminants to coastal ecosystems is a global problem on the rise. Data on metal pollution from tropical sites is often lacking and pilot surveys are urgently needed to provide a general framework to estimate the relative impact of these and other pollutants. The objective of this study was to make accessible data on trace metals collected during pilot surveys (2000)(2001)(2002)(2003)(2004)(2005)(2006) at four coastal embayments of Costa Rica. Cu, Fe, Mn and Zn were analyzed by Flame Atomic Absorption Spectrometry (FAAS) and Al, Cd, Ni, Pb and Sn by Graphite Furnace Atomic Absorption Spectrometry (GFAAS). Concentrations of Fe, Pb, Zn, Mn, and Ni were determined by FAAS or GFAAS, in tissues of the rock snail Acanthais brevidentata, the infaunal bivalves Anadara tuberculosa and Tagelus affinis (from three Pacific sites: Culebra Bay, Gulf of Nicoya, and Golfito Bay) and in the clam Polymesoda arctata from the Caribbean coast (Moín Bay). In addition, Sn, Cd and Cu were evaluated in tissues of T. affinis. A group of specimens of T. affinis was depurated for 72 hours in filtered seawater from the collection site. Concentrations varied between and within sites and also between parts of the same The relatively high concentration of Pb was probably related to the use at the time of sampling of leaded fuel in small boat operations at the site, while no evident cause was found for the high Mn values. Depuration was partially effective in lowering the metal burden in T. affinis. Data gathered during the pilot survey were indicative of relatively clean conditions of Culebra Bay, while the other three sites have important concentrations of certain contaminants, including metals. In spite of the fact that this data was collected more than a decade ago, it remains as the most recent available on trace metals from coastal mollusks of Costa Rica. Rev. Biol.
