REPLY OF THE STATE TOXICOLOGIST DR. F. PLAVSICTO THE ARTICLE "TOXIC AND HARM MATERIALS IN DAILY USE

"In recent months appeared on the different sides the self-appointed toxicologists who even published a book( “The E numbers and the food additives” written by spouses Vrcek) and to whom is not known the basic concepts of toxicology. This time drove my the reaction engineer Tatijana Malacko in her article" The materials in the application although the toxic and carcinogenic "(Vjesnik, February 18^th 2005).
 

The lady, her like-minded the Vrčeks, shows they do not know the basic concepts of toxicology, and sources of data collected this entire group as "toxicologist", are very strange.
Complete a nonsense to claim that PET packaging or Teflon cancerogenic or that aspartame is the culprit for many harmful effects in diabetic patients who take them. I wonder just why the diabetologists such claims have not responded. I emphasize once again that it is total ignorance ... and I was still ashamed to write that these are even people who have listened to lectures on my postgraduate course in toxicology.
 

No one from the authors of such claims could find data in official database of the European Union or the World Health Organization (WHO), the authors of stories about dangerous teflon or PET packaging such information could not be found. I looked at, for example, data on Teflon in a very respectable base Micromedex and found what I already know. Teflon is inert, insoluble in water solutions and there is no possibility of its penetration into the body, either through the digestive system or skin.
It could get into the lungs when it would develop, during cooking, aerosol of teflon, which seems highly unlikely. It has long been known that at temperatures above 600 degrees Celsius leads to degradation of Teflon with the low formation of a hazardous substances, including the worst perfluoroizobutilen (known as a cause of death of our citizens in Baxter dializator disaster), but it is not a carcinogen.

A similar story is with the PET packing, from which it may release small molecules (eg color), if it contains. It is insoluble in water and therefore no possibility to be in any way absorbed into the bloodstream, and is not a carcinogen. So much for the information of new sources of Toxicology.

In the toxicology is still important to understand the relationship between dose and effect, as new toxicologists do not understand, despite what they wrote about it before a lot of medieval scholars hundreds of years ago. Of course anything can be poison, including the clear spring water, but toxicology deals with dose where toxicity really start to happen and the harmful effects of dose on the basis of such substances are classified according to risk. Thus for inst.toxicologists salt did not classify as poisons, despite the serious poisonings recorded by this important chemical.

Any hazardous substance at certain small dose will not cause any harmful effects but only when it exceeds the specified limit risk. So we freely intake into the body by smoking cyanides, cyanides or biotransformation in the body resulting from amygdalin, which in turn we take through bitter almonds or apricot kernels. Of course we enjoy without consequence because there are toxic materials in doses well below those that may cause adverse effects first.

Our food is full of toxins, created naturally or by metabolism of bacterias and mold. While there is a low doses of these toxins, we must not overlook the fact what we eat. That does not mean that we should not care about the health safety of food or the cleanliness of the air we breathe, but it has nothing to do to health safety and toxicology( Not quite correct,TM).

Safety is, usually expressed with a maximum permissible concentration (MPC) or recommended concentrations, talking about safety and not on risk. Engineer Malacko question of who has set these limits, I am instructing her to first learn about the basic concepts and only after that public her opinion on the issues that troubles her.
Although I do not have enough space to explain, I must point out that the acceptable daily intake is calculated from which MDC or recommended concentration, calculated by dividing by a factor of safety (10-10000, depending on model and type of adverse effect) at the maximum dose that can not yet occur any more adverse effects.
 

Malacko engineer must also know that these values ​​are calculated the world's leading experts on the basis of experiments that are carried out simultaneously in several well-controlled laboratory with GLP (Good Laboratory Practice) certificates.
Do you really need to listen to ignorant people who appear like a false prophet, scaring the inhabitants by their ignorance? Everyone, of course, has the right to say whatever comes to mind him and so, for example, that the earth was flat, but one should also be publicly responded as the ignorant who write stupidities. "

PS: MALACKO ENGINEER WORKED 15 YEARS WITH PESTICIDES SO KNOWS ALL ABOUT TOXICITY AND LD, THAT IS VISIBLE FROM ALL POSTED ARTICLES, BUT FUNNY, VJESNIK REJECTED TO PRINT HER DEFENSE!
