Health risk of heavy metals in street dust

Abstract

Heavy metals in street dust represent a risk to the human health due to their toxicity, persistence and bioaccumulation. Using the US Environmental Protection Agency (USEPA) assessment, here, we review the human health risks of such dust worldwide. The street dust in such cities is contaminated by As, Cd, Cr, Cu, Hg, Mn Ni, Pb and Zn beyond the median levels of the world soil background values. Among these elements, the median values of the hazard risk indices (non-carcinogenic risk) are highest for As, Cr and Pb and the median values of the risk indices (carcinogenic risk) for As are in the tolerable risk range for children and adults and in the case of Pb, the median value of the carcinogenic risk indices are also in the tolerable range for children. We emphasize that the level of heavy metals in street dust pose a considerable risk to the human health and require monitoring and approaches to reduce such toxic levels.

Potential Health Effects of Heavy Metals and Carcinogenic Health Risk Estimation of Pb and Cd Contaminated Eggs from a Closed Gold Mine Area in Northern Thailand

“…Therefore, Hg is an international priority in terms of toxic pollution and is now a major global concern [ 12 , 15 ]. Pb and Cd are also a threat to human health because of their carcinogenic nature [ 16 , 17 ]. According to the International Agency for Research on Cancer (IARC), they fall into Group 2B (Possibly carcinogenic to humans) and Group 1 (Carcinogenic to humans), respectively.…”

Heavy metal analysis in of indoor and outdoor dust extracts and cytotoxicity evaluation and inflammation factors on lung, gastric and skin cell lines

“…DPs are important routes for loading HMs into the human body [ 19 ]. The health risks posed by HMs in indoor and outdoor DPs have attracted particular attention [ 20 , 21 , 22 ]. https://journals.sagepub.com/action/doSearch?target=default&ContribAuthorStored=Naimabadi%2C+Abolfazl Previously, Naimabadi et al.…”

Metals, Nanoparticles, Particulate Matter, and Cognitive Decline

“…Intoxication with heavy metals is a global health problem (5) as is the extensive environmental Al pollution (2) and the metal exposures associated with outdoor and indoor particulate matter (PM) in urban environments (6,7). Exposure to metals is ubiquitous and emission sources are heterogeneous: gasoline, diesel, alternative mixed biofuels, contaminated soil, water and food, medical implants, waste recycling facilities, subway, lubricating oils, and occupational environments (8)(9)(10)(11)(12).…”
