Is stainless steel kitchen sink safe？

The sink is one of the most frequently used utensils in the kitchen. It is wear-resistant, scratch-resistant, non-stick and oil-free, and environmentally friendly and healthy has always been the direction people pursue.

Food-grade SUS304 stainless steel sinks are safe under normal use conditions and will not cause heavy metal poisoning. The main components of stainless steel include iron, chromium and other metals. These metals themselves are non-toxic and can form stable compounds to provide corrosion protection. In stable forms, these metals are not toxic to humans. However, during prolonged exposure to acids or in corrosive environments, small amounts of chromium may be released, but this release is usually not sufficient to cause significant toxic effects. To reduce risks, avoid using stainless steel sinks in severe impact or strong acid-base environments, and ensure the use of products that comply with national standards. Additionally, avoiding leaving food in hot or acidic environments for extended periods of time can also help reduce potential health risks.

If the stainless steel basin is severely impacted or is in a strong acid-base environment, it may cause some chromium to precipitate, increasing the risk of heavy metal poisoning. This is mainly due to the strong physical or chemical effects that destroy the protective layer on the surface of stainless steel, causing chromium ions to come into direct contact with food and be absorbed into the body.

In fact, a large part of the sinks on the market are made of 201 stainless steel. The performance of 201 stainless steel is not as good as 304 and it is easy to rust. What’s more serious is that when used on sinks and tableware, a large amount of manganese will precipitate, which is harmful to the human body, especially children. Harmful.

Long-term use of sinks with excessive heavy metals may cause the following hazards：

First of all, it affects the digestive system. After heavy metals enter the human body, they will first exist in the digestive tract. Therefore, excessive heavy metals will generally first cause damage to the digestive system, which can easily cause patients to suffer from nausea, vomiting, abdominal pain, loss of appetite and other uncomfortable symptoms.

Secondly, it affects the nervous system: it will interfere with the function of neurotransmitters and over-stimulate the sympathetic nervous system, which may lead to neurological abnormalities such as dizziness, coma, and convulsions.

Therefore, it is very important to choose a sink made of materials that do not contain heavy metals.

Granite sinks do not contain heavy gold metals and are a new generation of healthy sinks.
