FLUORIDE AND LEAD: WHY ARE THEY HARMFUL?
To fully understand the strong and urgent need to reduce gaseous emissions coming from industrial production, the main characteristics of the two most noxious substances emitted by the ceramic tile industry need to be outlined.

Fluoride is a toxic pollutant, which is not biodegradable and gradually builds up in the environment and therefore in the food chain. Fluoride is highly toxic and harmful to the health of human beings and animals. Those drinking large amounts of fluorinated water are more likely to suffer from arthritis, osteoporosis and precocious bones fragility.

The toxicity of lead is well known, and is absorbed mostly through breathing and eating. When ingested lead is not metabolised, and while is excreted, the rest (roughly 20%) is concentrated in the blood, in the mineral tissues (like teeth and bones) and in the soft tissues (like kidneys, bone marrow, liver and brain). Lead can damage almost all tissues, especially the kidneys and the immune system. The most subtle and dangerous signs of lead poisoning are manifested in the nervous system.
