Russian scientists confirmed the safety of black plastic
Russian experts conducted a study of kitchen utensils made of black plastic to check the content of dangerous substances, including brominated flame retardants (BAP), and came to an unequivocal conclusion: products sold in Russia are completely safe for health.
The study reassures housewives: they don't have to worry and get rid of the plastic spoons and spatulas that are so convenient to use. Mikhail Katsevman, Chairman of the Council of the Union of Plastic Processors, stressed that in Russia the use of BAP in consumer goods has been prohibited for many years. He noted that in the United States, only 36 states have imposed restrictions on the use of BAP, whereas in Russia such additives are prohibited at the legislative level. Special requirements apply to products for the food industry that undergo strict certification before entering the market. Experts also point to the limitations of the American study: testing was carried out on a small sample of goods purchased in one city and mainly in small shops where counterfeit products could be sold.
In contrast, in Russia, plastic products undergo mandatory certification according to GOST standards, which eliminates the possibility of toxic substances, kp.ru reports.
