Abstract Heterogeneity between ambient and personal exposure to heavy metals has been documented. However, few studies have investigated potential health risks posed by inhalational airborne metal(loid)s at the individual level. A total of 404 fine particles (PM 2.5 ) samples were collected from 61 adult residents (aged 18–63 years) in Hong Kong during 2014–2015. Heavy analyzed using energy dis...

eight selected heavy metals (cu, zn, pb, cd, cr, mn, fe and al) in surface and sub-surfacesediments in the northern coast of sfax (tunisia) were studied in order to assess the sediment quality and tohighlight the anthropogenic contributions to heavy metal distributions in the two study sediment levels.multiple chemometric approaches based on geographic information system (gis), enrichment facto...

This Chapter covers the emissions of airborne particulate matter (PM) from road transport which are due to vehicle tyre and brake wear (SNAP code 070700) and road surface wear (SNAP code 070800). PM emissions from vehicle exhaust are not included. The focus is on primary non-exhaust particles in other words those particles emitted directly as a result of the wear of surfaces and not those resul...

environmental pollution of soil, plants and deposits around highways endanger urban environment through heavy metals as the by-products of vehicles and urban industries along with other pollutants. in this research, three main highways of tehran city; namely shahid chamran, shahid hemmat and yadegar emam which had the highest rate of vehicle transportation were selected and required sampling wa...

Aerosol mass spectrometer (AMS) measurements are used to characterize the evolution of exhaust particulate matter (PM) properties near and downwind of vehicle sources. The AMS provides time-resolved chemically speciated mass loadings and mass-weighted size distributions of nonrefractory PM smaller than 1 microm (NRPM1). Source measurements of aircraft PM show that black carbon particles inhibit...

Background & Aims of the Study:  Heavy metals are ubiquitous in the environment, as a result of both natural and anthropogenic activities, and humans are exposed to them through various pathways, especially food chain. So, this study aimed to assess heavy metals (Cu, Pb and Zn) concentrations in different parts of the leek vegetable in Hamedan Province, Iran. Materia...

OBJECTIVE To determine the blood lead levels and trace elements (copper and manganese) in traffic police constables in Islamabad in order to assess the effects of environmental pollution on the levels of metals in body fluids. METHODS Blood samples were collected from 47 male traffic police constables, 21 to 45 years of age, posted in different areas of Islamabad and controlling traffic from ...

Introduction: The aim of the present study was to determine the levels of alpha particles and heavy metals contamination in the meat products consumed in Najaf, Iraq. Moreover, this study was also targeted toward comparing the results with those in the literature and making appropriate conclusion and recommendations. Material and Methods: This study determined the track of alpha particles and ...
