A quoted by CNN, the WHO recently took the the position that these measures, despite being seen/practiced in some countries, are largely ineffective (and also dangerous if people are directly exposed to some disinfectants)

WHO cited studies showing that trying to spray bleach or other chemicals over a wide area is ineffective. The same goes for ultraviolet light disinfecting, the agency said. [...]

“spraying disinfectants can result in risks to the eyes, respiratory or skin irritation and the resulting health effects,” WHO said. “Spraying or fogging of certain chemicals, such as formaldehyde, chlorine-based agents or quaternary ammonium compounds, is not recommended due to adverse health effects on workers in facilities where these methods have been utilized." [...]

“Spraying or fumigation of outdoor spaces, such as streets or marketplaces, is also not recommended to kill the COVID-19 virus or other pathogens because disinfectant is inactivated by dirt and debris and it is not feasible to manually clean and remove all organic matter from such spaces,” the agency said.

What are these studies (that spraying disinfectants in public spaces is largely ineffective) and is this an uncontroversial conclusion, at least in academic publications?
