Can someone just explain slowly to my DH why bleach is bad for the environment.

[PeachesMcLean]

Please?
What exactly does it do.

It sets off my alarm that detects carbon monoxide, smoke and other impurities.

But is it bad to put it down drains,

Or tip a whole bottle down the loo.

This says no, peaches.:

Fair enough, thank you lljkk.

I've now confessed my mistake to DH, who is feeling smug now. Damn!

alkaline is as bad for the environment as acids.
it changes the ph of wherever the water goes to afterwards - eg rivers. and makes it harder for native species to breathe etc. the end result is that algae (or some other alkali - tolerant organism) can take over, take the nutrients from the native species and so the habitat changes.
or something like, that, been a while since my degree / masters.

but it is bad to tip a whole load down the sink.

Scienceteacher, would you care to elaborate?

it is bad for fish

it can also react with other cleaners and give off toxic gas

It doesn't do much except turn everything white!! No point putting it down your toilet as it won't don anything.

yes

it's probably more harmful than the germs tbh

Oh and domestos ........it doesn't kill 99.9% of all known germs dead - that's crap!
