Other potential routes include skin contact with sealcoat and abraded sealcoat particles and contaminated soil, sediment, dust, and water.
Survey participants were asked questions regarding activities that may have influenced exposures through contact with contaminated solids (e.g. soil, sediment, dust, mine materials).
He and colleagues hoped to find complete and detailed lake sediments of dust and vegetation remains from a site within the Sahara, but such sites are rare as most of the Sahara's lakes have dried over the past 7000 years.
Recently, a few studies have been conducted on surface sediments from dust source regions, e.g., the Asian interior (Maher et al. 2009; Zan et al. 2015) and North Africa (Lyons et al. 2010, 2012; Oldfield et al. 2014).
Exposures to dioxins in soil, river sediments, household dust, historic emissions, and contaminated fish and game were of primary interest.
In the central and eastern U.S., PAH fingerprints of lake sediment and dust from sealcoated parking lots were similar, and were different from fingerprints of lake sediment and dust in the western U.S., reflecting regional differences in sealcoat product type used.
Experts fear a mine could taint the region's water with increased sediment, coal dust and nitrates from explosives.
Understanding the relationship between horizontal flux and the vertical component of sediment and dust is critical to predicting fundamental processes such as erosion, and to assessing human and environmental risks associated with contaminated sediment and dust.
Magnetic susceptibility is used worldwide as a measure of concentration of (ferri magnetic minerals in soil, sediment and dust.
The present study was designed to probe the levels of heavy metals (Cd, Pb, Cr, Mn, Cu, Ni, Zn and Fe) for different environmental matrices (ground water, wastewater, sediment, soil, dust and leachates).
