The resuspension of indoor particulate matters caused by people indoor walking could affect indoor air quality and human health. Therefore, it is particularly important to study the resuspension rules of the particulate matters in different indoor environments. The influence of the ground material and the relative humidity on resuspension of the particulate matters were investigated under three kinds of ground materials and three different relative humidity. Results showed that different relative humidity and different ground materials had different effects on the mass concentration of the particulate matters. In addition, different particle sizes had diverse influence on the mass concentration. Compared with low-level loop pile carpet and shaggy carpet, hardwood floor was more conductive to human health which was less likely to cause the resuspension of the particulate matters. At the same time, relative humidity had a great influence on the resuspension of the particulate matters. With the increase of relative humidity, the resuspension rate of fine particulate matters decreased.

Fine particulate matter (PM) is linked to dementia risk, but ultrafine particles (UFPs, <100 nm) may be even more toxic due to their distinct physicochemical properties. However, evidence on UFPs and dementia remains limited. This study assessed the association between UFP exposure and Alzheimer's disease (AD) and related dementias (ADRD) among U.

Background: Ischemic heart disease (IHD) remains a major public health challenge in China. This study aimed to comprehensively analyze the burden of IHD, its risk factors, and future trends from 1990 to 2021 using the Global Burden of Disease database.
Methods: We assessed IHD trends in incidence, prevalence, mortality, and disability-adjusted life years (DALYs) stratified by age (greater than 15 years) and gender.

: Exposure to fine particulate matter (PM) causes significant respiratory and gastrointestinal health problems. In our prior research, we identified TW01 as a promising strain for mitigating oxidative damage, enhancing wound healing in intestinal epithelial cells, and protecting bronchial cells from cigarette smoke extract. Building upon these findings, this study examines the protective effects of this strain on lung damage induced by particulate matter (PM) through the gut-lung axis in mouse models.

Air pollution, particularly particulate matter (PM), poses a significant health risk worldwide, with rhinitis emerging as a prevalent respiratory condition. This review explores the association between air pollution and rhinitis, focusing on PM-induced inflammation and the potential preventive role of nutritional supplements. A comprehensive literature search was conducted using the PubMed and Scopus databases, covering studies from inception to 2024 that investigated air pollution, rhinitis, and nutritional interventions.

In this study, a series of cerium dioxide catalysts with varying hydrothermal temperatures and times were synthesized using the hydrothermal method, without the use of templates. The impact of varying hydrothermal conditions on the activity of cerium dioxide catalysts was investigated through experiments to examine their oxidation characteristics in soot combustion. Among the conditions tested, the hydrothermal conditions of 140 °C and 6 h yielded the most optimal catalytic oxidation of soot, with a combustion characteristic temperature () of 552 °C and a reduction of 122.
