Paints that I use for my art.

In what way do I contribute to water pollutions?
I haven't thought about the paints that I use for my oil paintings. Though, The paints contain various kinds of chemical components. My favorite colors which are Cerulean Blue, Cadmium red and Titanium white have chemical component of cobalt, cadmium and Titanium in it and there are more kinds of chemicals in others. Where people get those is to mine the ground just like they do to get coal, silver, golds and things for jewelries. And also what the another example is that getting uranium for nuclear power source.
Mining has been the great impact to the water pollution, however, the problem of using the paints is that those can cause skin cancer to use them in the daily basis.
As an oil painter, I have some choice of not to use those harmful pigments. Some of the paints labeled "Hue," this means the pigment is artificially made. so its it doesn't have the same type of chemicals, but those colors have not as beautiful and genuine color as traditional pigments have.
Since I have been oil painting for 6 years and probably will continue to paint, I have to be careful using those chemicals. However, as I became aware of those facts, I found myself having difficult time caring of my health because when I'm painting, it's important to focus just on the artwork. Caring about getting my hand dirty would be a destruction. I could wear a plastic grabs for protecting my hands, but then I don't feel close to the painting and lose the ability to interpret my creativity into the artwork.
This struggle has become an issue in my own by caring the environment and myself. I care the environment as much as I do to myself in a sense that I feel that I'm a part of the nature. About the paints that I use, I basically demand the real colors that are extracted in mining, but if I use artificial which is cheap quality of color image but not getting through the mining process.
So my personal struggle continues.
