A comparative study of heavy metal concentration and distribution in deposited street dusts in a large and a small urban area: Birmingham and Coventry, West Midlands, UK

Cadmium contamination in various environmental materials in an industrial area, Hangzhou, China

“…British Geological Survey, Wikipedia, 2008). Numerous papers suggest that Cd pollution in city environments might be fairly common (Li et al, 2001;Charlesworth et al, 2003;Zhang et al, 2004;Lin et al, 2007). Recently, in new investigations of the national resources in China, regional Cd anomaly belts were found in the alluvium of the Yangtze River (Cheng et al, 2005).…”

Variation in soil chemistry related to different classes and eras of urbanisation in the London area

“…The relationship between Pb and other elements associated with road traffic (Harrison, 1979;Warren and Birch, 1987;Ward, 1990;Leharne et al, 1992;Charlesworth et al, 2003;Robertson et al, 2003;Thornton, 2012) was evaluated in the GLA by examining how these elements vary with proximity to different classes of roads. Ordnance Survey OS Open Roads data was used to calculate distances between soil sample sites and roads (Supplementary material Figure SM-5).…”

Effects of road dust on the growth characteristics of Sophora japonica L. seedlings

“…Studies on the effects of dust loads outnumber those on dust composition and grain size. In previous artificial dusting studies, several dust load treatments were compared (Armbrust, 1986;Shukla et al, 1990;Charlesworth et al, 2003;Kuki et al, 2009), concerning loam, fly ash, iron dust, and cement dust. As for the dust composition's effects on plants, in the ore dust studies, ore element contents and plant characteristics were often linked (Kuki et al, 2008;Neves et al, 2009).…”

“…Road dust includes high concentrations of heavy metals, such as Cd, Cr, Cu, Pb, and Zn (Charlesworth et al, 2003;Tang et al, 2013), which are different in composition from natural dusts such as loam. To highlight the dust composition effects of road dust, we used loam from an unpolluted rural area for comparison.…”
