I bought a mineral water in train and started reusing the bottle unaware of the fact the chemical leaches from the bottle i used the bottle for 60 days however the water in the bottle was always left at room temperature never more than that only on 2 3 occasion out of 60 days  i left it sunlight that too for 30 minute maximum i used to replace the water after every 2 or 3 days I used to drink maximum 2 litre a day because it was winter time after releasing its health hazard after 60 days i threw the bottle .i am scared about the chemical leaching will it cause cancer necessarily??
