Talk:Selenium dioxide

Safety needs reworking
The Safety section of the article is misleading. Selenium dioxide is classified as toxic and its adverse effects are well documented. The article makes it sound like ingestion of selenium dioxide is harmless. 131.111.185.34 (talk) 09:43, 17 January 2018 (UTC)

Use as toner
"It was also used as a toner in photographic developing" It "is" also used as a toner, not "was".
