Absolutely horrible for those who will be affected by damages and clean-up costs. | ||

The metals won't do an aweful lot anyway. And to people who say stuff like "it's got a high pH so it's toxic", they are wrong. CaOH and NaOH are not classed as toxic, they are classed as corrosive. Yes, they damage skin and you'd probably die if you drank enough of it. However, they are not poisons, which is what the "toxic" label on chemicals normally means. Poison: + Show Spoiler + http://www.thefreedictionary.com/poison n. 1. A substance that causes injury, illness, or death, especially by chemical means. 2. Something destructive or fatal. Toxic: + Show Spoiler + http://www.thefreedictionary.com/toxic adj. 1. Of, relating to, or caused by a toxin or other poison 2. Capable of causing injury or death, especially by chemical means; poisonous Do you have some doubt on the health implications such an extreme pH has on fish or other plants & animals? If a pH13 solution cause injury illness or death, then by definition that solution is a poison, and it can be described as "Toxic" I haven't been able to find any definition of either of these terms that wouldn't apply to this sludge so far. | ||

NaOH, CaOH are not toxins, they are corrosive. There is a difference. Stop using retarded definitions for laymen and you will go a long way. | ||

Stop using retarded definitions for laymen and you will go a long way. Toxicity requires context. Example 1: H20 can be toxic to humans. http://en.wikipedia.org/wiki/Water_intoxication Example 2: Your negative statement against "definitions" and how people should stop using them is toxic to the English language. Example 3: Huge quantities of pH 13 sludge pouring into topsoil and into a stream is toxic to countless organisms. | ||

A stone is capable of causing injury and death and by your definition would be "a poison, and it can be described as "Toxic". That's ridiculous. To decide whether chemicals are toxic they are normally given to rats, mice or other small animals in different doses. The dose that causes half of the animals to die is a common measure for toxicity. Those numbers are usually quite small. For metallic arsenic it's 4.5 mg/kg. For Sodium Hydroxide it's something like 500 mg/kg. Yes, it still harms you, but neither sodium nor calcium hydroxide are classed as toxic by any government or official chemical organisation that I know. The difference is that something truly toxic will cause serious problems even at low levels. However, based on the list of chemicals that are alledgedly in the sludge, you could easily dip your hand in it, rinse it off and you'd be fine. Yes, it would probably irritate your skin, but you sure as hell won't die. | ||

Stones can be toxic to your health in the following context: http://en.wikipedia.org/wiki/Stoning There is nothing in the definition of toxicity that specifies a maximum quantity of the substance to still have an impact. All the same here is another example involving rocks: Small rocks inserted into some ones brain would be quite toxic to a person's health. By the way as flattered as I am, I'm not actually the guy that writes the dictionary, none of these definitions are "mine" that's why I gave a source. EDIT: Rather than continue this futile line of questioning why don't you just go read the link manifesto posted, I'll quote a relevant section for you right now to put an end to it. The chemicals extinguished all life in the Marcal river, and reached the Danube River on 7 October, prompting countries located further down the river to develop emergency plans in response. "Extinguished all life in the Marcal river." Is there any further dispute? | ||

They are not even trying to save them, thinking about re-establish instead :S Edit: a shitload of pics. There are more images if you click on an actual one. Edit2: And btw the government is dumbfuck as it can be. They are telling we have enough money and manpower to recover by ourselves... and ofc it's not true. | ||

"Extinguished all life in the Marcal river." Is there any further dispute? You're quite funny. Yes, yes, everything is toxic. But if everything is toxic, then what's the point of calling the sludge toxic? After all the trees, houses, fish and the river before the accident were also "toxic", weren't they? The label is used so that we can distinguish between substances that cause harm in low doses and substances or materials that don't. You will never find water with a label on saying toxic. You won't find sodium or calcium hydroxide with a toxic label on either. Of course you can call them what you like. By the way, nobody was denying that there was damage to wildlife. It just doesn't look like there were any truly toxic materials involved. That's a good thing of course, because that way the damage won't last nearly as long. | ||
