PAM poisonous?

In contact with the dealer just did, and chat with friends and the products of the company, ask the most is the question of polyacrylamide poisonous? On this issue to discuss here , hope to just touch this product friend useful.

Some cation type PAM situation is much more complicated, this is because of the introduction of cationic polyacrylamide amino groups such as, its toxic often dozens of hundreds of times higher than to anionic type and non-ionic, their chronic toxicity is further study.

A reference to a period of online copied material: the U.S. food and drug administration think, PAM and its water collapse the low-toxic and non-toxic. PAM from the toxic residual acrylamide monomer and the production process the entrainment of toxic metal. Acrylamide as neurological to agents, on the nervous system damage effect, after the poisoning of table to the body, the symptom such as movement disorders. So all the health department all have provisions polyacrylamide industrial products of the residual acrylamide content, general is 0.5% ~ 0.05%. Application in water purification processing general, acrylamide content below 0.2%, used for direct drinking water treatment, need to under 0.05%. Polyacrylamide standard WHO was born in 1985 by the International Health: residues in PAM AM control and control the amount of less than 0.05%, the content of treated water will be lower than 0.25ug / L, in line with most national standards for drinking water . At present main countries Europe and the general provisions, drinking water treatment and food with PAM residual AM content below 0.05%, and control PAM dosage.

Through the above material, can be very intuitive said PAM non-toxic product itself, because it is entering the human body, most in the short run out of body, is rarely gastrointestinal absorption. Most commodity also does not stimulate skin, and only certain water collapse may have residual alkali, when repeated, long-term contact will there be irritating, so manufacturers and dealers at contact can need not worry about the hazards.

Corresponding used for drinking water treatment of flocculant, should use food grade products for appropriate. In the water drainage standard to standardize the implementation of manual "water treatment standards, specific provision PAM used the often use next > 0.1 mg/L, often used in the < 0.1 mg/L. The water treatment technology of help in the application, and its use for the most desirable standard dosing quantity, the choose and buy food grade high quality, low salvage value of polyacrylamide goods, it can guarantee the health security of drinking water. As a water use polyacrylamide help clots, maximum dosing quantity of 0.09 mg/L, use chemical engineering center of guangzhou PAM food-grade, ponds and water were not found the factory tap water acrylamide monomer. So think only need to be able to control the quality of the product and good use dosing quantity, used the polyacrylamide help of technology is safe drinking water for health.
