do they damage environment? how do they react with diff things?

Copper Sulphate is definately a poison, but funnilly enough is used in the most unexpected areas considering its toxicity!
It can be used to plate metals with copper, as a fungicide or herbicide, or as a chemical test for water (the anhydrous form will absorb water, turning blue). Mixed with lime it is called Bordeaux mixture. It is also used in Fehling's solution and Benedict's solution to test for reducing sugars, which reduce the blue Cu2+aq ions to red copper(I) oxide. In addition, Copper (II) Sulphate is also used in Biuret solution to test for proteins. If proteins are present, a violet coloration is obtained. Still other uses include hair dyes and the processing of leather and textiles.
Copper sulphate is also used to test blood for anemia. A drop of the patient's blood is dropped into a container of copper sulfate, if it sinks within a certain time, then the patient has sufficient hemoglobin levels and is not anemic. If the blood floats or sinks too slowly, then the patient is iron-deficient and may be anemic.
In a flame test, copper ions emit a deep blue-green light, much more blue than the flame test for barium.
Copper(II) sulphate is a desiccant.
Copper sulphate is a commonly included chemical in children's chemistry sets and is often used in high school crystal growing and copper plating experiments.
A very dilute solution of Copper sulphate is used to treat aquarium fish of various parasitic infections. However, as the copper ions are also highly toxic to the fish, care must be taken with the dosage.

Copper sulphate is poisonous as are all copper salts. Most other heavy metals are toxic to varying degrees however some like iron, manganese, zinc are beneficial and only poisonous in large ammounts. Then there is things like gold which are fairly inert and don't cause any problems
The toxic ones are bad for the environment as they are toxic to plants and animals but each will cause varying damage. Some will remain in the envirinment longer than others

Copper sulphate contains the Cu2+ which is somewhat poisonous to most living organism if ingested in vast amounts.
But first of all, Cu2+and Cu+ are important cofactors in many proteins, because of their reductive/oxidative abilities.
But unmediated intake of copper ions can set your system of out balance.....30 grams is said to be lethal to humans.
differetn reason for it's toxicity:
It can block the protein involved in the formation of blood cellular components.
It's ability to donate/acceptate single electrons can form dangerous radicals in the organism.......such as the hydroxyl radical.
Otherwise, it just screw up your metabolism........or any metabolism if you eat signicant amounts.
Yep, heavy metals is poisonous in the wrong amounts.

Copper sulfate is poisonous. Transition metal compounds Are poisonous. But as Paracelsus said, poison is in the dose.

Not really.
But heavy metal ions like lead and mercury are very harmful to human body!

CuSO4 has many uses... and yes, of course its poisonous...
