Is polyacrylamide PAM harmful?

When buying products, some customers will ask whether polyacrylamide is dangerous goods, there is no harm to the human body.Current data show that polyacrylamide itself and water disintegration are non-toxic and harmless, and its possible toxicity comes from its residual monomer acrylamide.After such a long time of technological upgrading, the production process of polyacrylamide has been very mature, the residual monomer acrylamide is very few.And polyacrylamide is generally used in the industrial field, the amount of polyacrylamide in the cosmetic field is relatively small, and the content is extremely small.As the workers of polyacrylamide manufacturers, now dust control and protective measures are very perfect, there is no possibility of ingestion, let alone ordinary users.

Health departments of all countries have stipulated that the acrylamide residue in polyacrylamide industrial products is generally 0.5%-0.05%.When used for industrial and municipal sewage purification, the acrylamide content is generally not more than 0.2%, and when used for direct drinking water, the acrylamide content should be less than 0.05%.The new chemicals are produced in strict accordance with the specified targets.

According to the 1985 World Health Organization standard for polyacrylamide, when the amount of residual acrylamide in polyacrylamide is controlled to less than 0.05% and the amount is controlled, the treated water content will be less than 0.25 microgram/l, meeting most drinking water standards.PAM products have been approved by the U.S. Environmental Protection Agency (EPA) or the U.S. Food and Drug Administration (FDA) for use in areas such as drinking water, clarifying sugar and juice, and washing fruits and vegetables.PAM is non-toxic, but its raw material monomer AM is toxic, especially to the nerve damage of mammals.Therefore, * in Europe and the United States, including China, have strict requirements on the content of residual monomer AM in food-grade PAM, which is generally less than 0.05%.Large dose applications are also limited, for example in the fields of wastewater treatment and sludge dewatering.
