People, please stop spreading conspiracy theories. Some of you should be smarter than this.

Let me debunk this conspiracy theory floating around suggesting spike in SO2 emissions in Wuhan is due to massive burning of bodies

1/
2/ According to this 2018 Green Peace report on global SO2 emissions, annual SO2 emissions from Wuhan is:

85 Kilotons per year

greenpeace.org.au/wp/wp-content/…
3/ The average SO2 emission from cremation of a human body is found in this paper. Specifically table 2

ncbi.nlm.nih.gov/pmc/articles/P…
4/ EDITED to correct for decimal point.

Based on this, I calculated relative % of daily SO2 emissions for 100, 1000, and 10000 bodies cremated.
5/ Even if 10k bodies were cremated each day, it would only represent 0.3% of average daily SO2 emission in Wuhan.

Therefore, any spike can not be due to cremation
6/ Primary source of SO2 emission are from coal power plants (don't think volcanos are present in Wuhan).

If the scrubbers in a power plant malfunctions, you will get spikes

greenpeace.org.au/wp/wp-content/…
7/ Medical waste (hospital gowns, etc.) is also a potential source. Medical waste typically contain 0.2% sulfur.

It'd not surprise me that this may be the source of spikes. If incinerator cap. is @ max. I can imagine med waste being burned in open fields
8/ For example, many latex and nitrile gloves contain sulfur-containing rubber vulcanization accelerators. This improves elasticity, resilience, and tensile strength.

9/ Other sources of SO2 emissions.

Municipal waste.

10/ Pollution is a big problem in Wuhan. Including a garbage to energy plant.

11/ an even more thorough debunking - that data was not real.
