Lead (Pb) is one of the most frequent hazardous air contaminants, where the lungs are
particularly vulnerable to its toxicity. However, the Pb distribution and its impact on lung …

Lead (Pb) is recognized as the first heavy metal of the top six toxic air pollutants threatening
human health and the second hazardous substance. Pb exposure is associated with lung …

Nitropyrene (1-NP), a key component of fine particulate matter (PM2. 5), is a representative
of nitrated polycyclic aromatic hydrocarbons (NPAHs). The aim of this research is to …

Wide application of TiO 2 nanoparticles (nTiO 2) and ubiquitous lead (Pb) pollution in
natural environment enhance the chance of co-exposure of humans to Pb and nTiO 2. We …

In this work we have attempted to characterize the programmed cell death (apoptosis) in
alveolar macrophages exposed to various concentrations of lead nitrate. It was found that …

Despite the wide spread of lead environmental pollution, the effect of this heavy metal on
respiratory disease was not shown yet. In respect to increased oxidative stress is an …

Abstract Benzo [a] pyrene (B [a] P) is present in environmental pollution and cigarette
smoke. B [a] P has been shown to induce apoptosis in hepatoma cells, human B cells …

Abstract Benzo [a] pyrene (BaP), a representative polycyclic aromatic hydrocarbon, exists
widely in automobile emissions and polluted atmosphere. The current study aimed to …

Black carbon (BC) and heavy metal lead (Pb), as typical components of atmospheric PM 2.5,
have been shown to cause a variety of adverse health effects. However, co-exposure to BC …

Dimethyl benz (a) anthracene (DMBA), when injected intratracheally once at a dose of 20
mg/kg body weight, is found to induce lung cancer in rats. Two nonsteroidal anti …
