Are there still any factual arguments against design flooring with Blue Angel?
Vinyl floors are also just PVC – they were only renamed because the term "PVC" is rightly considered tainted.
The production of PVC polymer based on petroleum and rock salt already releases dangerous pollutants: among others, dioxins. Substances in this group can enter the air, groundwater, and soil. They decompose biologically only very slowly, accumulate especially through food intake in animal and human fat tissue, and are toxic to varying degrees. The most poisonous dioxin, 2,3,7,8-tetrachlorodibenzodioxin (TCDD), for example, has been classified as carcinogenic by the World Health Organization (WHO) since 1997 and is extremely toxic even in the smallest amounts.
To make the brittle and hard PVC in its raw state moldable, floor manufacturers use plasticizers. In further processing, phthalates are still frequently used, which are legally regulated in children's products. These are not chemically bound in the material. They can enter the human body primarily through household dust and continuously escape from the floors – only when the material becomes porous is it assumed that the contained plasticizing substances have fully or at least largely evaporated. According to the Federal Institute for Risk Assessment, phthalates are "now detected everywhere in the environment." In Western Europe alone, the annual production volume amounts to around one million tons. More than 90 percent go into the manufacture of soft PVC products such as flooring.
Often additional substitute plasticizers are also used. These compounds have not yet been sufficiently investigated for possible health risks! Dibutyltin is also often contained as a UV stabilizer; this can already impair the immune and hormone systems of animals and presumably humans at smaller doses.
Another topic is the substances used as flame retardants, such as tributoxyethyl phosphate (TBEP), which is considered irritating to skin and eyes. Or other organophosphorus compounds, which are considered highly hazardous to water.
