It seems to many that injuries and accidents are the only risks associated with fireworks.. In fact, fireworks should be feared for other, more significant reasons: according to US scientists, they contain dangerous toxins and metals like copper and even lead, which lead to air pollution and are dangerous to health..

“Fireworks are a real dilemma for me,” said Dr Gary Fuller from King’s College London.. - On the one hand, they give people a lot of pleasant emotions, and on the other hand, they pollute the air with the same harmful substances that get there as a result of the work of factories and factories.. Among these substances are copper, barium, strontium and perchlorates.. As a result, on the most festive days, the level of pollution in cities increases significantly.”.

Perchlorates are a negatively charged group of atoms consisting of a central chlorine atom bonded to four oxygen atoms.. Perchlorates can form in the atmosphere and are colorless and odorless.. These substances are water soluble and have also been found in plumbing and food.. Perchlorates are harmful to health because they disrupt the normal functioning of the thyroid gland, which plays an important role in metabolism and produces hormones that help regulate heart rate, blood pressure, body temperature and the rate of conversion of food into energy..

According to scientists, fireworks contain other toxic chemicals dangerous to human health that negatively affect the pulmonary and cardiovascular systems.. That's why they recommend thinking twice before buying fireworks for any occasion..
