| Jun 24, 2021 at 8:04 | comment | added | Nilay Ghosh | Continuing Mithoron's comment: H2O is liquid others are gas. So, how do they contribute to toxicity? Because of its volatility and smell. Due to them being gas, they have the tendency to have higher exposure to human body than water, so they are more prone to be to smelly and toxic.

| May 21, 2021 at 7:28 | comment | added | Nilay Ghosh | Tangentially related question: chemistry.stackexchange.com/questions/4636/… One of the answer says: "The bio-degradation of sulfur compounds mostly leads to some sulfides which very strongly bind transition metals, i.e. they can destroy/block Metalloenzymes". The same might occur with selenide and telluride. | |

| Apr 29, 2021 at 23:33 | comment | added | orthocresol | Chemistry within a group is not as similar as the Periodic Table might lead one to believe (except, perhaps, in groups 1 and 2). You should already know that first-row elements (B, C, N, O, F) stand out in terms of e.g. hydrogen bonding. I'm not trying to say that toxicity is caused by the lack of hydrogen bonding, I'm just trying to point out that there are substantial differences between O and S (and beyond), and perhaps it's not all that surprising after all. | |
