The emissions include a myriad of toxic air pollutants and carbon dioxide CO 2 , which is the most important human-produced climate-altering greenhouse gas. Synergies between air pollution and climate change can magnify the harm to children. The developing fetus and young child are disproportionately affected by these exposures because of their immature defense mechanisms and rapid development, especially those in low- and middle-income countries where poverty and lack of resources compound the effects. No country is spared, however: even high-income countries, especially low-income communities and communities of color within them, are experiencing impacts of fossil fuel-related pollution, climate change and resultant widening inequality and environmental injustice. Global pediatric health is at a tipping point, with catastrophic consequences in the absence of bold action. Fortunately, technologies and interventions are at hand to reduce and prevent pollution and climate change, with large economic benefits documented or predicted.

Biomass and biofuels made from biomass are alternative energy sources to fossil fuels—coal, petroleum, and natural gas. Burning either fossil fuels or biomass releases carbon dioxide CO2 , a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source. Using wood, wood pellets, and charcoal for heating and cooking can replace fossil fuels and may result in lower CO2 emissions overall. Wood can be harvested from forests, from woodlots that have to be thinned, or from urban trees that fall down or have to be cut down.

Carbon monoxide is an odorless, colorless and toxic gas. Because it is impossible to see, taste or smell the toxic fumes, CO can kill you before you are aware it is in your home. The effects of CO exposure can vary greatly from person to person depending on age, overall health and the concentration and length of exposure. Acute effects are due to the formation of carboxyhemoglobin in the blood, which inhibits oxygen intake. At low concentrations, fatigue in healthy people and chest pain in people with heart disease.

Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil. Natural gas emits 50 to 60 percent less carbon dioxide CO2 when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant [ 1 ]. The drilling and extraction of natural gas from wells and its transportation in pipelines results in the leakage of methane, primary component of natural gas that is 34 times stronger than CO2 at trapping heat over a year period and 86 times stronger over 20 years [ 3 ]. Whether natural gas has lower life cycle greenhouse gas emissions than coal and oil depends on the assumed leakage rate, the global warming potential of methane over different time frames, the energy conversion efficiency, and other factors [ 5 ]. One recent study found that methane losses must be kept below 3.

Carbon monoxide CO —a colorless, odorless, tasteless, and toxic air pollutant—is produced in the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood. The largest anthropogenic source of CO in the United States is vehicle emissions. Breathing the high concentrations of CO typical of a polluted environment leads to reduced oxygen O 2 transport by hemoglobin and has health effects that include headaches, increased risk of chest pain for persons with heart disease, and impaired reaction timing.

Carbon Monoxide's Impact on Indoor Air Quality

Carbon capture and storage CCS , or carbon capture and sequestration and carbon control and sequestration , [1] is the process of capturing waste carbon dioxide CO 2 , transporting it to a storage site, and depositing it where it will not enter the atmosphere. Usually the CO 2 is captured from large point sources , such as a cement factory or biomass power plant , and normally it is stored in an underground geological formation. The aim is to prevent the release of large quantities of CO 2 into the atmosphere from heavy industry , and so help to limit climate change.

Carbon capture is one of the foremost methods for curtailing greenhouse gas emissions. Incumbent technologies are inherently inefficient due to thermal energy losses, large footprint, or degradation of sorbent material. We report a solid-state faradaic electro-swing reactive adsorption system comprising an electrochemical cell that exploits the reductive addition of CO 2 to quinones for carbon capture. The reported device is compact and flexible, obviates the need for ancillary equipment, and eliminates the parasitic energy losses by using electrochemically activated redox carriers.

Он хоть и крупный, но слабак.  - Она кокетливо улыбнулась Беккеру.  - Не волнуйтесь, он ни слова не понимает по-испански. Беккер нахмурился. Он вспомнил кровоподтеки на груди Танкадо.
