This study aims to provide technical support for the development of a rational administration strategy for indoor environment and passenger flow of stations. The analysis was conducted monitor data of long distance bus stations and train/high speed railway stations from the National project. The monitor and surveyed data included indoor airborne culturable bacteria (IAB), passenger flow, area and height of stations.

Indoor air quality (IAQ) of urban public transportation stations (UPTS) has adverse health impacts on the station employees and commuters. However, there is a lack of comprehensively evaluations of IAQ in waiting rooms of UPTS. Therefore, it is crucial to select appropriate air quality indexes (including fuzzy synthetic index (B), comprehensive index (P), I index, and indoor air quality index (IAQI)) to assess air quality and potential health risks.

Article Synopsis
  • Several studies have linked outdoor noise to depression, but this study investigates indoor noise levels and their association with depression symptoms, focusing on hotels across multiple cities.
  • The research involved analyzing over 10,500 indoor noise level measurements and health data from 2,402 hotels, finding that about 40.9% exceeded recommended noise levels, with nearly 19.1% of workers showing depressive symptoms.
  • The results indicated a significant positive correlation between higher indoor noise levels and increased depression scores, particularly affecting younger female workers in major cities, with suggestions made for implementing noise control measures in hotels.

Residential formaldehyde pollution is one of the leading residential harmful pollutants with a large production and consumption globally and remains much uncertainty in Chinese families with huge health burden for children worldwide. A multi-center observation study from 11 cities was conducted to investigate residential formaldehyde pollution levels measured by phenol reagent spectrophotometry. Data on household characteristics and schoolchildren's health were collected by questionnaire.

Residential airborne culturable bacteria (RAB) are commonly used to assess indoor microbial loads, which is a very effective and recognized indicator of public concern about residential air quality. Many countries and organizations have set exposure limits for residential bacteria. Nevertheless, few studies have been conducted in multicenter cities about the distribution and influencing factors of RAB.

Background: New alternative phthalates have been increasingly substituted for certain phthalates in some consumer products due to safety concerns. However, research on the steroidal effect of exposure to the newer replacement phthalates in the general adult population is lacking.

Objectives: This study aimed to examine the associations of exposure to the older generation and newer replacement phthalates with sex hormone levels in the U.

To explore the pollution characteristics of metals in household dust in China and their exposure to children, this study searched peer-reviewed papers published during 1980-2020 and analyzed 30 eligible papers screened under the per-decided strategy. We evaluated the sample-weighted concentration (SWC) of each metal, explored the sources of metals, and presented the quantitative description of spatial-temporary characteristics and children exposure to 13 metals with multi-route under a general living scenario. The results showed the concentrations of 13 metals with a range of 0.

Polycyclic aromatic hydrocarbons (PAHs) in indoor dust are one of the common exposure sources for children worldwide. The aim of this study is to explore PAHs pollution status in indoor dust and estimate health risk on Chinese children with big data. Weighted average concentration was used to analyze source and characterization of PAHs in indoor dust based on peer-reviewed literature.

Residential air pollution can cause a large disease burden, and residential air quality is directly influenced by residential fine particulate matter (PM). Residential PM pollution is of critical concern in China given that the characteristics and influencing factors of residential PM in China are not clear. This study focuseed on residential PM concentration of 12 cities with the on-site investigation in 2018, and provided the latest characteristics and potential influencing factors of residential PM under general living scenarios in China.

Elderly persons are vulnerable to infectious diseases, and nutritional status and health conditions were important to evaluate for disease prevention and ability to recover for the elderly during the coronavirus disease 2019 (COVID-19) pandemic. In our study, a rapid assessment questionnaire was used to investigate the change of household life and dietary intake of the elderly (aged 60 years or more) during community closure. Food consumption frequency of aquatic food products, soybeans, and fresh fruits declined dramatically with reductions of 70.

This study examined indoor air pollutants and their health effects on allergic rhinitis in 3194 employees of 226 bus station halls and then constructed a nomogram model to predict allergic rhinitis risk in those employees. Indoor air temperature, relative humidity, PM , PM , total bacteria, and total fungi were measured, and questionnaires were used to collect basic station information and employee health information. The results revealed that the over-standard rates of PM , PM , total bacteria, and total fungi were 18.

Objective: To project the future impacts of climate change on heat-related mortality in shanghai.

Methods: The statistical downscaling techniques were applied to simulate the daily mean temperatures of Shanghai in the middle and farther future under the changing climate. Based on the published exposure-reaction relationship of temperature and mortality in Shanghai, we projected the heat-related mortality in the middle and farther future under the circumstance of high speed increase of carbon e mission (A2) and low speed increase of carbon emission (B2).
