Demonstrating the temporal changes in PM pollution risk in regions facing serious PM pollution problems can provide scientific evidence for the air pollution control of the region. However, research on the variation of PM pollution risk on a fine temporal scale is very limited. Therefore, we developed a method for quantitative characterizing PM pollution risk based on the supply and demand of PM2.5 removal services, analyzed the time series characteristics of PM pollution risk, and explored the reasons for the temporal changes using the urban areas of Beijing as the case study area. The results show that the PM pollution risk in the urban areas of Beijing was close between 2008 and 2012, decreased by approximately 16.3% in 2016 compared to 2012, and further decreased by approximately 13.2% in 2021 compared to 2016. The temporal variation pattern of the PM2.5 pollution risk in 2016 and 2021 showed significant differences, including an increase in the number of risk-free days, a decrease in the number of heavily polluted days, and an increase in the stability of the risk day sequence. The significant reduction in risk level was mainly attributed to Beijing's air pollution control measures, supplemented by the impact of COVID-19 control measures in 2021. The results of PM pollution risk decomposition indicate that compared to the previous 2 years, the stability and predictability of the risk variation in 2016 increased, but the overall characteristics of high risk from November to February and low risk from April to September did not change. The high risk from November to February was mainly due to the demand for coal heating during this period, a decrease in PM removal service supply caused by plant leaf fall, and the common occurrence of temperature inversions in winter, which hinders the diffusion of air pollutants. This study provides a method for the analysis of PM pollution risk on fine temporal scales and may provide a reference for the PM pollution control in the urban areas of Beijing.

The abundance of chemical elements in the blood of horses can indicate the physiological balance, health of animal as well as can be taken as an indicator of environmental pollution. The aim of this work was to analyse haematological, biochemical parameters, TOS, FRAP, SOD, Gpx, TAS and their correlations with concentrations of essential and risk elements in blood of horses stabled in two different locations: The National Stud Farm Topoľčianky (n = 11; 11 stallions, consisting of the breeds 6 Lipizzan, 3 Slovak warmblood, 2 Holsteiner) and Experimental Centre at Institute of Animal Husbandry, SUA in Nitra (n = 10; 4 stallions, 5 geldings, 1 mare, 4 stallions, 5 geldings and 1 mare, consisting of the breeds 3 Slovak warmblood, 4 Czech warmblood, 3 Holsteiner). Blood samples were obtained from horses (n = 21) from two localities in the Slovak Republic during May.

Studies investigating the relationship between exposure to air pollutants during pregnancy and foetal growth restriction (FGR) in women who conceive by in vitro fertilisation (IVF) are lacking. The objective was to investigate the effect of air pollutant exposure in pregnancy on FGR in pregnant women who conceive by IVF. We included pregnant women who conceived by IVF and delivered healthy singleton babies in Guangzhou from October 2018 to September 2023.
