A study released Wednesday by the National Research Council said that the potential risk of nanotechnology still needs to invest 24 million US dollars a year. The United States should set up a new federal regulatory body to integrate research from private enterprises, universities and international organizations. Achievements 。

The study was sponsored by the environmental protection agency of the United States, and a committee of 19 scientists conducted the study. Nanometer Technology is currently widely used in antifouling fabrics, cosmetics and food additives.

In 2009, sales of related products were about $225 billion, and the next 10 years will also increase rapidly.

The results of the study are as follows: "although nanotechnology has great prospects, there is no relevant risk at present and how to manage and avoid it. risk Conduct strategic research. The prospects for safe and sustainable nanomaterials, products and processes are still uncertain. At present, the impact of human engineering on the environment, health and safety of nanomaterials is not fully understood.

The CDC says there are indications that nanoparticles can penetrate the skin and enter other organs from the respiratory system.

According to the report, half of the nanomaterials come from ceramic nanoparticles, and the other 20% come from carbon nanotubes and nano porous materials.

In the 2012 annual budget, the federal government allocated $123 million 500 thousand to study the safety of Engineering nanomaterials, and the budget will remain stable in the next 5 years.

In addition, public, private and international organizations will invest $5 million a year to collect and disseminate information about engineering nanomaterials and invest $10 million in engineering nanomaterials.
