New particle formation (NPF) in the tropical upper troposphere is a globally important source of atmospheric aerosols1,2,3,4. It is known to occur over the Amazon basin, but the nucleation mechanism and chemical
produce high flame temperatures that resulted in the production of nitrogensoxides, which is then emitted to the atmosphere =-=[1]-=-.sJurnal Mekanikal, December 2008s97sGlobal environmental problems such as greenhouse warming, acid rain andshole in the ozone layer have become serious problems...
2–5). The chemical ionization atmospheric pressure interface ime-of-flight (CI-APi-TOF) mass spectrometer can detect highly oxidized ELVOCs as well as inorganic species such as sulfuric acid41,42,43, which cause NPF (Methods). The CI-APi-TOF data were strongly dominated by the mononitrate ...
Generally, BIFs contain at least 15 wt.% bulk Fe and often show spectacular alternating millimetric (microbands) to metric silica and Fe(III) oxide or Fe(II) silicate layers1,2,3. According to a consensual model, the large-scale accumulation of Fe required that dissolved Fe(II) sourced...
In the formation of acid rain, sulfur dioxide reacts with oxygen and water in the air to form sulfuric acid. Write a balanced chemical equation for the reaction. Write a balanced chemical equation for this chemical reaction. Include the physical state of...
Primer pairs targeting a genome region that is contiguous only on cccDNA ("over-gap PCR") can achieve 100- to 1000-fold discrimination [50], and further physical enrichment is possible [67]. However, accurately determining reductions of the anyhow low HBV cccDNA levels, ...
Such sulfate aerosols influence the surface temperature of the Earth7, acid rain formation8,9, and human health10, playing a key role in environmental chemistry and climate change6,11,12. Therefore, knowing the source(s) of aerosol sulfate and its transport and transformation in the atmosphere ...
One of the least understood aspects in atmospheric chemistry is how urban emissions influence the formation of natural organic aerosols, which affect Earth’s energy budget. The Amazon rainforest, during its wet season, is one of the few remaining places
2 & Tae Sup Yun 1* Enzymatically induced carbonate precipitation (EICP) using urea hydrolysis is a well-known bio- cementation process that not only promotes the precipitation of calcium carbonate (CaCO3) but can provide excess calcium cations for further reaction depending on the ...
Therefore, local natural sources, in combination with boundary layer transport of precursor gases from the open pack sea ice region, are thought to be significant contributors to the detected aerosol population. Further information on chemical and physical aerosol properties are presented in the next ...
