4 days ago · Lay people were cautious about a depletion of the ozone layer and the risks of skin cancer. Satellites burning up upon re-entry into Earth's atmosphere produce aluminum oxide (Al 2 O 3 ) nanoparticles that endure in the atmosphere for decades. [17]
5 days ago · The massive columns of smoke generated by a nuclear war would alter the world's climate for years and devastate the ozone layer, endangering both human health and food supplies, new research...
4 days ago · Known as tropospheric or "ground-level" ozone, this gas is harmful to human heath and the environment. Since it forms from emissions of volatile organic compounds (VOCs) and nitrogen oxides (NOx), these pollutants are regulated under air quality standards.
3 days ago · Feature, Ozone Layer Wildfires: An Unexpected Threat to the Ozone Layer’s Recovery By Vivek Saini As the world reflects on the remarkable progress achieved in repairing the ozone layer, once a symbol of environmental crisis, the emergence of a new threat underscores the ongoing vulnerability of this vital atmospheric shield.
2 days ago · The internet also requires the depletion of other natural resources beyond carbon, namely land, water, electromagnetic spectrum and minerals. Electronic waste contributes in particularly acute ways to environmental pollution. This document surveys the impacts of the internet on the environment and includes, but goes beyond, energy use and ...
3 days ago · Before climate change emerged as a global issue, the UN’s top environmental concern was the depletion of the ozone layer. The ozone layer keeps the amount of ultraviolet (UV) light reaching humans at a healthy level, but by the late 1970s it began to weaken, increasing millions of people’s exposure to sunburn and some cancers.
4 days ago · Abstract This paper presents the results of calculations of the length of ozone destruction chains in the lower stratosphere in HOx-, NOx-, and ClOx-catalytic cycles, taking into account heterogeneous chemical reactions (HCRs) involving particles of the Junge layer. Taking into account these reactions leads to a change in the type of high-altitude profiles of the length of the chains in these cycles, calculated in the approximation of the absence of HCRs. At the lower boundary of the Junge ...
