Background: Gestational diabetes mellitus (GDM) can have negative effects on both the pregnancy and perinatal outcomes, as well as the long-term health of the mother and the child. It has been suggested that exposure to air pollution may increase the risk of developing GDM. This study investigated the relationship between exposure to air pollutants with gestational diabetes.
Methods: The present study is a retrospective cohort study. We used data from a randomised community trial conducted between September 2016 and January 2019 in Iran. During this period, data on air pollutant levels of five cities investigated in the original study, including 6090 pregnant women, were available. Concentrations of ozone (O), nitric oxide (NO), nitrogen dioxide (NO), nitrogen oxides (NOx), sulphur dioxide (SO), carbon monoxide (CO), particulate matter < 2.5 (PM) or <10 μm (PM) were obtained from air pollution monitoring stations. Exposure to air pollutants during the three months preceding pregnancy and the first, second and third trimesters of pregnancy for each participant was estimated. The odds ratio was calculated based on logistic regression in three adjusted models considering different confounders. Only results that had a < .05 were considered statistically significant.
Results: None of the logistic regression models showed any statistically significant relationship between the exposure to any of the pollutants and GDM at different time points (before pregnancy, in the first, second and third trimesters of pregnancy and 12 months in total) ( > .05). Also, none of the adjusted logistic regression models showed any significant association between PM exposure and GDM risk at all different time points after adjusting for various confounders ( > .05).
Conclusions: This study found no association between GDM risk and exposure to various air pollutants before and during the different trimesters of pregnancy. This result should be interpreted cautiously due to the lack of considering all of the potential confounders.

The World Health Organization Environmental Noise Guidelines provide source-based nighttime sound level (Lnight) recommendations. For non-aircraft sources, the recommended Lnight is where the absolute prevalence of high sleep disturbance (HSD) equals 3%. The Guideline Development Group did not provide an Lnight for wind turbines due to inadequate data.

Objective: To verify the association between different types of ambient ventilation in Central Sterile Supply Department (CSSD), fractional exhaled nitric oxide (FeNO) values, and respiratory symptoms of workers .
Methods: CSSD workers from five hospitals were evaluated in three different ventilation systems: negative air pressure, air conditioning, and natural ventilation. The prevalence of respiratory symptoms was evaluated by The European Community Respiratory Health Survey.

Significant variation in mercury (Hg) bioaccumulation is observed across the diversity of freshwater ecosystems in North America. While there is support for the major drivers of Hg bioaccumulation, the relative influence of different external factors can vary widely among waterbodies, which makes predicting Hg risk across large spatial scales particularly challenging. We modeled Hg bioaccumulation by coupling Hg concentrations in more than 21,000 dragonflies collected across the United States from 2008 to 2021 with a suite of chemical (e.

Objective: Prenatal alcohol and tobacco exposure continue to impact a significant portion of the US population every year. Differences in neighborhood environment may be a contributing factor. The current study examines whether prenatal alcohol and tobacco exposure differ by neighborhood environment.

Introduction: Exposure to environmental factors ( air pollution and second-hand tobacco smoke) have been associated with impaired lung function. However, the impact of environmental factors on lung health is usually evaluated separately and not with an exposomic framework. In this regard, breath analysis could be a noninvasive tool for biomonitoring of global human environmental exposure.
