The Astrazenecs eco-friendly, environmentally-friendly water-powered toilets have been the subject of some controversy recently after they were revealed to contain high levels of arsenic and lead.
The toilets are being marketed as environmentally friendly, but critics have said that the toilets are toxic to the environment and will not be able to properly filter the water and prevent the spread of bacteria.
The products were developed by an Austrian company called Ecofunk.
The toilet makers are selling their product at the European Greenmarket in the city of Bremen.
The European Commission is investigating the claims that the products contain toxic materials.
The EPA said that its investigators had found no evidence that the water used to make the toilets was contaminated with toxic materials, and that they did not find any evidence that these chemicals were present in the products.
The Environmental Protection Agency (EPA) is also investigating whether the toilets were unsafe, and if they had been contaminated with other substances.
However, some environmental groups are calling for the EPA to investigate the products further, saying that they are a new type of toilet that will not require a filter.
