Utilization of Activated Carbon Catalyzed Ozonation (ACCO) For Removal of Ciprofloxacin and Vancomycin from Hospital Wastewater.

Background: Hospital wastewater is considered by health and environmental researchers due to the presence of various hazardous chemical contaminants such as residual of antibiotics and other drugs. The conventional treatment processes are not able to complete removal of them, and could lead to the entry of these compounds into the environment. Then, we aimed to analyze and evaluate the removal of ciprofloxacin and vancomycin antibiotics from hospital wastewater.

Status of TNF-α and IL-6 as pro-inflammatory cytokines in exhaled breath condensate of late adolescents with asthma and healthy in the dust storm and non-dust storm conditions.

Exposure to airborne particulate matter (PM) can be considered as an important risk factor for human health. Some cytokines have been recognized as the biomarkers of exposure to air pollution. Experimental studies indicate that PM exposure could be associated with inflammation.

Associations between short term exposure to ambient particulate matter from dust storm and anthropogenic sources and inflammatory biomarkers in healthy young adults.

This study examined the association between particulate matter from anthropogenic and natural sources and inflammatory biomarkers, including hs-CRP, IL-6, sTNF-RII, and WBCs, in two groups of healthy young subjects. We followed up subjects of two panels (16 to 22 years old), including 22 subjects selected from the urban area (Tehran city) with high-level pollution background and 22 subjects selected from the rural area (Ahmadabad) with low-level pollution background. In each group, we collected 4 times blood samples in various air pollution conditions, In the subjects of the urban group, there was a substantial difference (p < 0.

The acute effects of short term exposure to particulate matter from natural and anthropogenic sources on inflammation and coagulation markers in healthy young adults.

Airborne particulate matter is associated with increasing the risk of cardiovascular diseases. The purpose of this study was to investigate the association between air pollution conditions and MDA, vWF, and fibrinogen markers in the blood of two panels of healthy young individuals in an urban area in Tehran city with a high air pollution background and another group was living in a rural area (Ahmad Abad Mostofi), with a low air pollution background. In each group, 4 blood samples were taken as follows: one in inversion days, the second in winter, but during the existence of normal condition in terms of air pollution, the third sample in the spring during the normal condition in terms of air pollution and the fourth sample during the dust storm conditions.

Proinflammatory effects of dust storm and thermal inversion particulate matter (PM) on human peripheral blood mononuclear cells (PBMCs) in vitro: a comparative approach and analysis.

Particulate matter (PM) as the carcinogenic air pollutants can lead to aggravated health outcomes. Epidemiological studies demonstrated that PM can be engaged in different diseases such as cardiovascular, respiratory and cancer. The in vitro secretion of proinflammatory cytokines by human peripheral blood mononuclear cells (PBMCs) has been used to assess the effects of PM with an aerodynamic diameter < 10 μm (PM).

Physiochemical characteristics and oxidative potential of ambient air particulate matter (PM) during dust and non-dust storm events: a case study in Tehran, Iran.

In the present study, we investigated the characteristics of metal(loid)s, polycyclic aromatic hydrocarbons (PAHs) and oxidative potential (OP) in PM during dust and non-dust days in a rural and an urban area in Tehran. Water-soluble ions, metal(loid)s, PAHs, and OP were measured using ion chromatography (IC), inductively coupled plasma optical emission spectrometer (ICP-OES) and gas chromatography/mass spectrometry (GC-MS), and dithiothreitol (DTT) assay respectively. The results showed that the average concentrations of ambient PM were 284 ± 90.

Correction to: Investigation and Comparison of In Vitro Genotoxic Potency of PM Collected in Rural and Urban Sites at Tehran in Different Metrological Conditions and Different Seasons.

The original version of this article unfortunately contained a mistake. Figure 6 caption should be "The light microscopic image (a) and transmission electron microscopic image (b) of A549 cell after 24 h of exposure to PM10 (150 μg/ml).

On the chemical nature of precipitation in a populated Middle Eastern Region (Ahvaz, Iran) with diverse sources.

This study reports on the chemical composition of rainwater collected at three ground sites with varying degrees of pollution in Ahvaz, Iran, between January 2014 and February 2015. A total of 24 rainwater samples were analyzed for pH and concentrations of trace elements (Fe, Al, Pb, and Cd) and major ions (Na, NH, Ca, Mg, HCO, NO, Cl and SO). Principle Component Analysis (PCA) was used to identify sources of the measured species.

Investigation and Comparison of In Vitro Genotoxic Potency of PM Collected in Rural and Urban Sites at Tehran in Different Metrological Conditions and Different Seasons.

The particulate matter has become a serious health problem in some large cities in the world. These particles are a complex mixture of chemical compounds which change based on location and time and, consequently, can cause different health-related effects. The exact mechanism of the effect of these particles is not yet known for certain.

Short-term effects of particle size fractions on lung function of late adolescents.

Although ambient air pollution has been linked to reduced lung function in healthy students, longitudinal studies that compare the response of asthmatic and healthy adolescents are lacking. To evaluate lung function responses to short-term ambient air particulate matter (PM, PM, and PM) levels, we conducted a study on high school students aged 15-18 years. The aim of this study was to assess effects of acute exposure to ambient air particulate matter (PM) on lung function in healthy and asthmatic late adolescents.
