The sink is one of the most frequently used utensils in the kitchen. It is wear-resistant, scratch-resistance, non-stick grease, environmental protection and health have always been the direction that people pursue.
Stainless steel coated sinks are very popular these days, but what are the health risks?
The nano coating is hydrophobic and oleophobic, easier to take care of, and has a Mohs hardness higher than stainless steel itself, so many people choose nano sinks.
Kitchen sinks have very high requirements for nano-coatings, which must reach food grade and must have food-grade certification, such as US EDA certification, EU AP certification, German cutlery certification, etc.
However, most nano sinks on the market are not food grade, and the nano coating is harmful to the human body.
The composition of nanocoatings is complex, which may cause widespread environmental pollution and bring potential risks to the environment and organisms. And considering that what is currently released from nanomaterials are "nanoparticles", this may indeed become one of the sources of environmental pollution in the atmosphere, water, and soil.
Judging from the current relevant research, nanoparticles have obvious toxicity to human organs, such as liver, lungs, kidneys, etc. If nanoparticles are ingested into the body, they may have unpredictable effects on the human reproductive and respiratory systems.
Once the nano-coating falls off, heavy metals will overflow from the stainless steel substrate, contaminating food and causing harm to the human body. Most of the base materials are made of non-food grade 201 stainless steel.
Therefore, try not to use coated stainless steel sinks.
