The dangers posed by rising temperatures and chronic air pollution in china
However, little information is available in China on possible modifiers of the health impact of thermal extremes, such as preexisting health status and population demographics. The characteristics of the involved samples were also compared with those of the total surveyed subjects in Supplementary Fig.
China is notorious for being a major polluter.
Air pollution in china article
We also simulated daily maps of temperature Tw during the study period using a well-developed WRF model ver. Fourth National Climate Assessment released in noted, for example, that a changing climate "could expose more people in North America to ticks that carry Lyme disease and mosquitoes that transmit viruses such as West Nile, chikungunya, dengue, and Zika. The CFPS drew a representative sample of Chinese population using a multi-stage probability strategy with stratification, for multiple study purposes Its effects can range from higher disease risks to rising temperatures. Emissions from these vehicles lead to the formation of photochemical smog containing respirable particles and ozone not only within the city but also in the surrounding regions. Specifically, the long-term exposures were evaluated in terms of the average annual values of the selected parameters within the county of residence of each individual before the survey date , referring to previous studies on chronic environmental exposures Articles from EHP, especially the News section, may contain photographs or illustrations copyrighted by other commercial organizations or individuals that may not be used without obtaining prior approval from the holder of the copyright. Figure 3. The PM2. According to the fully adjusted models, every 0. However, our findings are not conclusive because of the following limitations.
Meanwhile, national standards for ground-level ozone are only 1. Humans have pumped enough carbon dioxide into the atmosphere over the past years to raise its levels higher than they have been for hundreds of thousands of years.
Climate change in china
The temperature products of Earth-observing satellites, which scan the whole planetary surface within a 1—2 day time period, offer moderate coverage of spatiotemporal dimensions and have been utilized in health-related studies Therefore, higher scores reflect better mental health. There are many psychological mechanisms that also make an epidemiological linkage between environmental factors and mental health biologically plausible. We obtained the six-digit administrative code each code identifies a county-level geographic unit for each subjects and then geocoded all CFPS samples into a map of county-level administrative boundaries in , through matching their administrative codes. Universal kriging is a two-stage model. Continue Reading. However, research that simultaneously incorporates multiple indicators is needed to identify the actual environmental risk factors. The agency recorded 15 percent more days with unhealthy air in the country in and compared to the average from to The four most dangerous pollutants that are emitted include: sulfur dioxide SO2 , nitrogen dioxide NO2 , carbon monoxide CO , and particulate matter e. Concern about the health impacts of climate change can encourage the Chinese government to take appropriate action. Statistical examinations of our data suggest that MHS decrease is robustly related to increase in PM2. Air quality To examine the effects of the environmental factors that affect mental health, this study obtained data on air quality, residential greenness, and ambient temperature. Air pollutants cause less-direct health effects when they contribute to climate change. From to , the overall trend of poorer mental health suggested that benefits from less variability of temperature and improved air quality did not offset the negative impacts from changes in other factors. How has the poor air quality affected the people and the surrounding environment?
These larger PM particles may be more dangerous than PM10 particles. A woman in China wears a face mask to protect herself from air pollution.
Climate change and human health in china
However, media reports of industrial emissions of lead mainly from lead smelter facilities in rural areas have recently increased sharply, raising public awareness and concern. China is striving to quadruple its gross domestic product GDP of the year by , and consequently will face even more serious challenges in controlling emission of GHGs. Wu, Y. Heat waves, extreme weather, food supply disruptions, and other effects related to increased greenhouse gases can have negative impacts on human health. Climate change can also affect climate-sensitive infectious diseases carried by animal hosts or vectors; in China, these include schistosomiasis, Japanese encephalitis, Dengue fever, malaria, and Angiostrongylus cantonensis infection. Furthermore, although the difference-in-difference design could control unmeasured confounders, it has limited statistical power to detect weak associations, because variations in environmental changes e. The characteristics of the involved samples were also compared with those of the total surveyed subjects in Supplementary Fig. Environmental Protection Agency, The Chinese government has paid great attention to climate change, but so far, there has been limited focus on climate-related the health impacts. The surface temperature of the Earth can be obtained from multiple sources including routine climate monitors, satellite remote-sensing measurements, and climate model simulations such as the weather research forecast WRF model.
How has the poor air quality affected the people and the surrounding environment? According to the findings, the efforts to mitigate climate change and air pollution can bring extra benefits in aspect of human mental health.
Study design We designed a difference-in-difference study to link changes in mental health to changes in long-term exposure to environmental factors. The four most dangerous pollutants that are emitted include: sulfur dioxide SO2nitrogen dioxide NO2carbon monoxide COand particulate matter e.
Mandatory factory closures and bans on motor vehicles entering the city are implemented on days of heavy air pollution. Worldwide, bad outdoor air caused an estimated 4.
Air pollution in china causes
In any home, people can safeguard against indoor air pollution by increasing ventilation, testing for radon gas, using air purifiers, running kitchen and bathroom exhaust fans, and avoiding smoking. The Chinese government also prefers to release information only on PM10 particles and not larger PM particles.

However, less well-known is the fact that too much ozone at the ground level is also a public-health threat.
