What are nitrates and why are they a concern in drinking water?
Nitrates are naturally occurring compounds that can be found in soil, water, and air. They are a common contaminant in drinking water, particularly in areas with intensive agricultural activity. Nitrates can enter water sources through fertilizer runoff, sewage, and industrial waste. High levels of nitrates in drinking water can be a concern for human health, especially for vulnerable populations such as infants, pregnant women, and people with certain medical conditions.
The main health concern associated with nitrates in drinking water is the risk of methemoglobinemia, also known as blue baby syndrome. This condition occurs when nitrates are converted to nitric oxide in the body, which can bind to hemoglobin in red blood cells and reduce the amount of oxygen that can be carried to the body’s tissues. In severe cases, this can lead to respiratory problems, brain damage, and even death. Therefore, it is essential to remove nitrates from drinking water to ensure it is safe for consumption.
What is a Zero Filter, and how does it work?
A Zero Filter is a type of water filtration system that uses advanced technologies to remove contaminants from drinking water.
