OK To try and add some actual reality check to the comments I read i post the following. And yes, I would build this.

Plasticised PVC has been used for over 50 years without a single known case of it having caused any ill-health and the environmental effects of phthalates are known to be minimal. Academia and industry have continually worked together to address the concerns and conduct necessary research, making phthalates some of the most researched and best understood chemicals today.



Carcinogenicity

Some concerns have been expressed concerning carcinogenicity. In 1980s, liver tumour of rats and mice was reported upon an extremely high dosing of DEHP, but subsequent studies clarified that such effects are unique to rodents such as rats and mice and would not occur in primates such as monkeys. In 2000, the International Agency for Research on Cancer (IARC: an affiliate organisation of World Health Organisation - WHO) re-classified DEHP from Group 2B to Group 3 in their carcinogenicity evaluation, thus clearly showing that DEHP is not carcinogenic to humans. Tea and tap water (drinking water sterilised with chlorine) are also included in Group 3, which means that the carcinogenicity of DEHP is lower than that of coffee.



Endocrine Modulation

In past years concerns have been reported on about possible risks of PVC products related to endocrine modulation and alleged disruption of certain phthalates.



Phthalates are a large and diverse family of chemical substances with different hazard classifications regarding human health.



High molecular weight phthalates DINP, DIDP and DPHP, which are the most widely used in Europe, are not endocrine disruptors.

Low molecular weight phthalates DEHP, DBP, BBP and DIBP have all been classified as toxic to reproduction of category 1B.with hazard phrase H360 (“May damage fertility or the unborn child”)
