Ozone (O) is a key air pollutant that is produced from precursor emissions and has adverse impacts on human health and ecosystems. In the U.S., the Clean Air Act (CAA) regulates O levels to protect public health and welfare, but unraveling the origins of surface O is complicated by the presence of contributions from multiple sources including background sources like stratospheric transport, wildfies, biogenic precursors, and international anthropogenic pollution, in addition to U.S. anthropogenic sources. In this report, we consider more than 100 published studies and assess current knowledge on the spatial and temporal distribution, trends, and sources of background O over the continental U.S., and evaluate how it inflattainment of the air quality standards. We conclude that spring and summer seasonal mean U.S. background O (USB O), or O formed from natural sources plus anthropogenic sources in countries outside the U.S., is greatest at high elevation locations in the western U.S., with monthly mean maximum daily 8-hour average (MDA8) mole fractions approaching 50 parts per billion (ppb) and annual 4 highest MDA8s exceeding 60 ppb, at some locations. At lower elevation sites, e.g., along the West and East Coasts, seasonal mean MDA8 USB O is in the range of 20-40 ppb, with generally smaller contributions on the highest O days. The uncertainty in U.S. background O is around ±10 ppb for seasonal mean values and higher for individual days. Noncontrollable O sources, such as stratospheric intrusions or precursors from wildfires, can make significant contributions to O on some days, but it is challenging to quantify accurately these contributions. We recommend enhanced routine observations, focused fi studies, process-oriented modeling studies, and greater emphasis on the complex photochemistry in smoke plumes as key steps to reduce the uncertainty associated with background O in the U.S.

In 2019, ozone was responsible for about 365,000 premature deaths worldwide (6.21 million healthy life years lost) and acute ozone exposure led to 16,800 premature deaths in the European Union. The aim of the study was to estimate the influence of NO, NO, wind direction (WD) wind speed (WS), air temperature (TA), and total radiation (GLR) on ozone concentration levels.

Objectives: Survivors of intracerebral haemorrhage (ICH) are at high risk of incident depression, which is modified by social determinants of health (SDOH) and associated with worse functional outcomes. We sought to determine the role of prestroke SDOH in depression incidence after ICH to better characterise post-ICH outcomes.
Study Design: We analysed data from a cohort study of ICH survivors without prestroke depression, presenting at Massachusetts General Hospital between 2006 and 2017.

Otosclerosis is a well-known disease which mainly affects middle-aged female patients, causing conductive or mixed hearing loss. Diagnosis is essentially made through a complete audiometric battery testing, while treatment substantially relies on stapes surgery. In this study, we analyzed audiometric and Quality-of-Life data from 33 patients in order to refine the surgical indications (unilateral versus bilateral stapes surgery) and assess the best technique (stapedotomy versus partial stapedectomy) and timing of treatment.

Both the global and European energy sectors have been undergoing a deep transition for several years, associated with a reduction in the overall share of conventional coal-based energy in favor of new technologies, especially energy from renewable sources (RES). This transition is moving from centralized production towards distributed technologies and from providing only energy to end users towards combining innovative products and services with it. Electricity consumers are becoming prosumers connected to the grid and generating an increasing amount of energy.

The collaborative control of pollution and carbon emission reduction in industrial fields is crucial for improving regional air quality and mitigating climate change. However, to our knowledge, there is limited research regarding the collaborative control paths for reducing industrial pollution and carbon emissions. The present study assesses the potential for reducing emissions of air pollutants and carbon dioxide (CO) in the industries operating in the Hohhot-Baotou-Ordos (HBO) region of Inner Mongolia.
