“…Atmospheric pressure is an important factor affecting the concentration of pollutants. When the air pressure is high, there are many sinking airflows on the ground, which is easy to form a sinking temperature inversion layer, and it is difficult for pollutants to move and dilute to the upper atmosphere (Graham et al, 2023 ; Guo et al, 2022 ; Jury, 2020 ). It can be seen from Fig.…”

Currently, air quality has become central to global environmental policymaking. As a typical mountain megacity in the Cheng-Yu region, the air pollution in Chongqing is unique and sensitive. This study aims to comprehensively investigate the long-term annual, seasonal, and monthly variation characteristics of six major pollutants and seven meteorological parameters. The emission distribution of major pollutants is also discussed. The relationship between pollutants and the multi-scale meteorological conditions was explored. The results indicate that particulate matter (PM), SO 2 and NO 2 showed a “U-shaped” variation, while O 3 showed an “inverted U-shaped” seasonal variation. Industrial emissions accounted for 81.84%, 58% and 80.10% of the total SO 2 , NOx and dust pollution emissions, respectively. The correlation between PM2.5 and PM10 was strong ( R = 0.98). In addition, PM only showed a significant negative correlation with O 3 . On the contrary, PM showed a significant positive correlation with other gaseous pollutants (SO 2 , NO 2 , CO). O 3 is only negatively correlated with relative humidity and atmospheric pressure. These findings provide an accurate and effective countermeasure for the coordinated management of air pollution in Cheng-Yu region and the formulation of the regional carbon peaking roadmap. Furthermore, it can improve the prediction accuracy of air pollution under multi-scale meteorological factors, promote effective emission reduction paths and policies in the region, and provide references for related epidemiological research.

“…This finding raises concerns that climate change will continue to increase legionellosis incidence in the USA under current trends of more frequent days with temperatures above 90 °F and increased precipitation [39]. Numerous international studies have similar findings that increased precipitation [40–43], elevated temperature [40–42, 44, 45], and higher relative humidity [41–43, 46] are associated with increased community-acquired legionellosis cases and clusters. Future research is needed to understand the exposure pathways between changing hydrometeorological factors and LD infections.…”

Over the past two decades, the incidence of legionellosis has been steadily increasing in the United States though there is noclear explanation for the main factors driving the increase. While legionellosis is the leading cause of waterborne outbreaks in the US, most cases are sporadic and acquired in community settings where the environmental source is never identified. This scoping review aimed to summarise the drivers of infections in the USA and determine the magnitude of impact each potential driver may have. A total of 1,738 titles were screened, and 18 articles were identified that met the inclusion criteria. Strong evidence was found for precipitation as a major driver, and both temperature and relative humidity were found to be moderate drivers of incidence. Increased testing and improved diagnostic methods were classified as moderate drivers, and the ageing U.S. population was a minor driver of increasing incidence. Racial and socioeconomic inequities and water and housing infrastructure were found to be potential factors explaining the increasing incidence though they were largely understudied in the context of non-outbreak cases. Understanding the complex relationships between environmental, infrastructure, and population factors driving legionellosis incidence is important to optimise mitigation strategies and public policy.

Final waste processing in Indonesia adopts a landfill system. The Benowo landfill employs this system, which has a weakness in producing H2S and NH3 gases. The objective of this study was to assess the level of public health risk present in the Benowo landfill environment. The study design used was quantitative descriptive with a cross-sectional approach. The sample size consisted of 93 housewives selected using simple random sampling techniques, and gas measurements were conducted at two locations. The data analysis methods employed were univariate analysis and ARKL. The findings of this research demonstrated that the level of hydrogen sulfide (H2S) gas measured 0.02 ppm, while the concentration of ammonia (NH3) was 0.006 ppm. which were still below the quality standards set by East Java Governor Regulation No. 10 year 2009 regarding ambient air quality standards and stationary source emissions in East Java, where the limits for H2S were 0.03 ppm and NH3 were 2.00 ppm. The response dose value (Rfc) for H2S was 0.002 mg/m3, and for NH3 it was 0.5 mg/m3. The RQ value for H2S was greater than 1, indicating a potential risk, while the RQ value for NH3 was less than or equal to 1, indicating safety for the community. H2S gas poses a risk, whereas NH3 does not pose a risk to the communities in the Benowo landfill environment. It is recommended that individuals have a healthy lifestyle, and wear masks in the Benowo landfill environment and local government should be able to carry out the risk management through related agencies to the people lived near Benowo landfill area.
