Source apportionment and environmental fate of lead chromates in atmospheric dust in arid environments

Paint particles in the marine environment: An overlooked component of microplastics

“…Paint particles from these sources are transported to the aquatic environment as airborne particulates that are subject to fallout, with road runoff or treated waste water, or via washdown from boat maintenance facilities or coastal structures undergoing repair. The significance of the local transport of airborne paint particles has been established from the levels and signatures of contamination of soils and roof top dusts of residential and municipal buildings in the vicinity of roads, dry docks, boatyards and harbours ( Decelis and Vella, 2007 ; Jartun et al., 2009 ; Turner, 2013 ; Eklund et al., 2014 ; Sakata et al., 2017 ; Meza-Figueroa et al., 2018 ). Given the particle size range generated by sanding (in the range of < 50 nm to a few μm in diameter; Koponen et al., 2009 ), however, the potential range of airborne transport of paint particles is considerable.…”

Lead and Chromium in European Road Paints

“…The composition, mineralogy, environmental dispersion and potential health impacts of road paints containing PbCrO 4 have been reported for specific locations in Japan (Ozaki et al, 2004;Adachi and Tainosho, 2004), the US (White et al, 2014;O'Shea et al, 2021), South Korea (Lee et al, 2016(Lee et al, , 2018 and Mexico (Meza-Figueroa et al, 2018) but there is a distinct lack of studies on road markings in Europe. Here, data appear to be limited to a few measurements of the Pb and Cr content of road paints in northwest England and southwest England as part of broader investigations of leaded paint in the urban setting (Sturges and Harrison, 1986;Turner and Solman, 2016;Turner and Lewis, 2018), and an assessment of road paint more generally as a source of microplastics, but not Pb, to the environment (Verschoor et al, 2016;Hann et al, 2018).…”

A Yellow Lead-Free Pavement Marking Paint Based on Hybrid Dye-Clay Nanopigment: Morphological, Thermomechanical, and Photophysical Properties

“…The massive public transportation infrastructure contains a substantial amount of lead (Pb) in the form of lead chromate pigment (PbCrO 4 ) inside yellow pavement markings. This pigment can leach out over time during its field application and migrate toward the air, soil, and water over a wide geographical area, causing serious health problems for living beings. − According to the statistical data reported by the World Health Organization (WHO), lead poisoning accounts for 0.6% of the global disease burden (GDB) and is responsible for more than one million deaths in 2017 . Nevertheless, only a few countries have established effective regulations to restrict the use of lead-based pigments in pavement marking paints so far. , One of the major obstacles that responsible organizations face in eliminating lead chromate from pavement marking formulations is the lack of an environmentally benign alternative yellow pigment that fulfills both economical and color performance requirements.…”
