Nitrates are an indicator of environmental and soil pollution. The limit set in Europe for nitrates is 50 mg/l for drinking water, 45 mg/l for mineral water and 10 mg/l for infant water. High nitrate values can seriously impede oxygen transport in the blood and combine with proteins to form nitrosamines, substances that are highly carcinogenic to our bodies.
It is understood, therefore, that the nitrate content of food and drink is a parameter to be controlled by those who are responsible for the nutrition of the whole family.
A low nitrate value in water therefore corresponds to greater purity and less pollution of its source, San Graziano Mineral Water with a value of only 2.3 mg/l is a pure water, ideal for the whole family.
