Malachite green is toxic to all caudates to some degree so you should probably not be using that anyhow. In any case, it's reactive and unless you are releasing significant amounts of it into the environment it is unlikely to pose a threat. Aside from that, the rest of the things on your list aren't toxic. Great stuff is completely inert - the problem with it is that it is not really biodegradable.
I think you need to look at pollution from the standpoint of your whole life rather than just your hobby. For example, the surfactants in most washing-up liquids are harmful to some degree. Probably the biggest issue for American households at least (they are far more active at recycling on average in much of the rest of the western world, but far worse in the developing world) is plastic container waste. Everything from the plastic film around DVD boxes to the plastic of a milk container is a huge problem in terms of how much it costs to produce (energy use, carbon dioxide emission), what is used to produce it (many plasticizers, the chemicals used to change the malleability of the plastic, are pseudo estrogens), to how long it takes to biodegrade (in the case of most plastics, they take far too long to begin to degrade in landfills).
I could talk about this subject for a few hours so I will try not to get carried away and leave it there.
