Contributions of local pollution emissions to particle bioreactivity in downwind cities in China during Asian dust periods. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2019; 245:675-683. [PMID: 30497001 DOI: 10.1016/j.envpol.2018.11.035] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2018] [Revised: 11/12/2018] [Accepted: 11/12/2018] [Indexed: 06/09/2023]
Abstract
This study investigated the effects of pollution emissions on the bioreactivity of PM2.5 during Asian dust periods. PM2.5 during the sampling period were 104.2 and 85.7 μg m-3 in Xi'an and Beijing, respectively, whereas PM2.5 which originated from the Tengger Desert was collected (dust background). Pollution conditions were classified as non-dust days, pollution episode (PE), dust storm (DS)-1, and DS-2 periods. We observed a significant decrease in cell viability and an increase in LDH that occurred in A549 cells after exposure to PM2.5 during a PE and DS-1 in Xi'an and Beijing compared to Tengger Desert PM2.5. Positive matrix factorization was used to identify pollution emission sources. PM2.5 from biomass and industrial sources contributed to alterations in cell viability and LDH in Xi'an, whereas vehicle emissions contributed to LDH in Beijing. OC, EC, Cl-, K+, Mg2+, Ca, Ti, Mn, Fe, Zn, and Pb were correlated with cell viability and LDH for industrial emissions in Xi'an during DS. OC, EC, SO42-, S, Ti, Mn, and Fe were correlated with LDH for vehicle emissions in Beijing during DS. In conclusion, the dust may carry pollutants on its surface to downwind areas, leading to increased risks of particle toxicity.

Watanabe M, Noma H, Kurai J, Sano H, Hantan D, Ueki M, Kitano H, Shimizu E. A panel study of airborne particulate matter composition versus concentration: Potential for inflammatory response and impaired pulmonary function in children. Allergol Int 2017; 66:52-58. [PMID: 27262618 DOI: 10.1016/j.alit.2016.04.014] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2016] [Revised: 03/29/2016] [Accepted: 04/24/2016] [Indexed: 10/21/2022] Open
Abstract
BACKGROUND The relationship between airborne particulate matter (PM) and pulmonary function in children has not been consistent among studies, potentially owing to differences in the inflammatory response to PM, based on PM types and sources. The objective of this study was to investigate the effect of airborne PM on pulmonary function in schoolchildren and its potential for an inflammatory response. METHODS Daily morning peak expiratory flow (PEF) was measured in 339 schoolchildren in February 2015. Interleukin (IL)-8 production was assessed in THP1 cells stimulated by airborne PM collected every day during the study period, and these IL-8 concentrations are described as the daily IL-8 levels. A linear mixed model was used to estimate the association between PEF values and the daily levels of suspended PM (SPM), PM diameters smaller than 2.5 μm (PM2.5), and IL-8. RESULTS The daily IL-8 levels were significantly associated with those of SPM and PM2.5. A 0.83 μg/mL increase in IL-8 levels was significantly associated with a -1.07 L/min (95% confidence interval, -2.05 to -0.08) decrease in PEF. A 12.0 μg/m3 increase in SPM and a 10.0 μg/m3 increase in PM2.5 were associated with a -1.36 L/min (-2.93 to 0.22) and -1.72 L/min (-3.82 to 0.36) decreases in PEF, respectively. There were no significant relationships between PEF, SPM, and PM2.5. CONCLUSIONS These findings suggest that the effects of airborne PM on pulmonary function in schoolchildren might depend more on the pro-inflammatory response than the mass concentration of the PM.

Mutagenic and genotoxic potential of native air borne particulate matter from industrial area of Rourkela city, Odisha, India. ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2016; 46:131-139. [PMID: 27458701 DOI: 10.1016/j.etap.2016.07.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2016] [Revised: 07/15/2016] [Accepted: 07/18/2016] [Indexed: 06/06/2023]
Abstract
In this study, we examined potential adverse health effect of particulate matter (PM) collected from industrial areas of Rourkela, Odisha, India. Results indicate that PM in these areas contains benzo[a]pyrene in addition to other unidentified molecules. Ames test revealed the above PM to be highly mutagenic. Further studies of PM in HaCaT cells suggest its DNA damaging potential which may lead to apoptosis. Generation of reactive oxygen and nitrogen species following PM exposure may be an early event in the PM induced apoptosis. In addition, the activity of cytochrome P450 (CYP450), the key xenobiotic metabolism enzyme, was found to be increased following PM exposure indicating its role in PM induced toxicity. To confirm this, we used genetic and pharmacological inhibitors of CYP450 like CYP1B1 siRNA and Clotrimazole. Interestingly, we found that the use of these inhibitors significantly suppressed the PM induced apoptosis in HaCaT cells, which confirm the crucial role of CYP1B1 in the toxic manifestation of PM. For further analysis, blood samples were collected from the volunteer donor and analyzed for immunophenotypes and comet assay to survey any change in immune cells and DNA damage in blood cells respectively. The study was performed with 55 blood samples including 32 from industrial areas and 23 people from non-industrial zone of Rourkela city. Samples had a mean±SD age of 35±6.2years (35 men and 20 women). Our investigation did not observe any significant alteration in lymphocytes (P=0.671), B cell (P=0.104), cytotoxic T cell (P=0.512), helper T cell (P=0.396), NK cell (P=0.675) and monocytes (P=0.170) of blood cells from these two groups. Taken together; this study first time reports the possible health hazards of PM from industrial areas of Odisha, India.
