“…Pb is a good example.`P ica'' consuming children ingest dust and soil at an average of rate of 10 g /day (Environmental Protection Agency, 1997). Pb content in house dust and soil is enriched by degrading Pb paint and proximity to heavily used streets and roads (Gulson et al, 1994;Elhelu et al, 1995;Lanphear et al, 1995;Sutton et al, 1995;Lemus et al, 1996;Madany et al, 1996;Emond et al, 1997;Lee et al, 1997;Rust et al, 1997). These studies indicate that soil and dust concentrations range from nondetectable to the milligram per gram range in contaminated areas.…”

NHEXAS AZ is a multimedia, multipathway exposure assessment survey designed to evaluate metals and other analytes. This paper reports the analytespecific concentration distributions in each of the media examined (air, soil, house dust, food, beverage, and water), for various methodologies used (inductively coupled plasma-atomic emission spectroscopy and hydride generation-atomic absorption spectroscopy). Results are reported for the five primary metals (Pb, As, Cd, Cr, and Ni). Ingestion was the most important pathway of exposure. Metal concentrations in air were very low (ng / m 3 ) and found only above the 90th percentile. Metals were commonly found in house dust and soil. Exposure transfer coefficients minimize the importance of this component for those over the age of 6 years. When ranked by exposure, food, beverage, and water appeared to be the primary contributors of metal exposure in NHEXAS AZ. For instance, at the 90th percentile, Pb was undetected in air, found at 131 and 118 g / m 3 in floor dust and soil, respectively, and measured at 16 g / kg in food, 7.1 g / kg in beverage, and 2.0 and 1.3 g / l in drinking and tap water, respectively. We calculated preliminary estimates of total exposure (g /day) for each participant and examined them independently by age, gender, and ethnicity as reported by the subjects in the NHEXAS questionnaire. At the 90th percentile for Pb, total exposures were 64 g /day across all subjects (n =176); adult men (n = 55) had the greatest exposure (73 g /day) and children (n =35) the least (37 g /day). Hispanics (n = 54) had greater exposure to Pb (68 g /day) than non-Hispanics (n =119; 50 g /day), whereas non-Hispanics had greater exposure for all other metals reported. These results have implications related to environmental justice. The NHEXAS project provides information to make informed decisions for protecting and promoting appropriate public health policy.

“…Although many of the pollutants identified in Table 3 may be present as either the dissolved or particulate phases, it is widely reported that the majority of the urban pollutant load is associated with particles which act as mobile substrates (Bjorkland, 2011;Herngren et al, 2006;Lee et al, 1997;McKenzie et al, 2008;Chiew 2002, 2004). The finer particles are more readily mobilised during rainfall as evidenced by reported particle size distributions for urban surface runoff (Table 4).…”

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.

“…heavy metals (lead, zinc, copper, cadmium, chromium and nickel), organic compounds, nutrients, solids, and de-icing agents [1,2]. These pollutants are often adsorbed to particles of different sizes [3][4][5]. One of the most common ways to treat stormwater is through sedimentation in different treatment facilities e.g.…”

Sedimentation is a widely used technique in structural best management practices to remove pollutants from stormwater. However, concerns have been expressed about the environmental impacts that may be exerted by the trapped pollutants. This study has concentrated on stormwater ponds and sedimentation tanks and reports on the accumulated metal concentrations (Cd, Cr, Ni, Pb, and Zn) and the associated toxicity to the bacteria Vibrio fischeri. The metal concentrations are compared with guidelines and the toxicity results are assessed in relation to samples for which metal concentrations either exceed or conform to these values. The water phase metal concentrations were highest in the ponds whereas the sedimentation tanks exhibited a distinct decrease towards the outlet. However, none of the water samples demonstrated toxicity even though the concentrations of Cu, Pb, and Zn exceeded the threshold values for the compared guidelines. The facilities with higher traffic intensities had elevated sediment concentrations of Cr, Cu, Ni, and Zn which increased towards the outlet for the sedimentation tanks in agreement with the highest percentage of fine particles. The sediments in both treatment facilities exhibited the expected toxic responses in line with their affinity for heavy metals but the role of organic carbon content is highlighted.
