Polyacrylamide itself is a non-toxic polymer and has a wide range of industrial applications, such as water treatment, chemical industry, papermaking, oilfield development, pulp and paper, mineral processing and other fields. However, polyacrylamide may contain residues of the monomeric acrylamide, which is a toxic neurotoxic agent that can cause damage to the nervous system and muscles. Therefore, in order to prevent possible poisoning, health departments around the world have strict requirements for the amount of acrylamide residues in polyacrylamide in industrial goods, which is generally specified as 05% or less.
In drinking water treatment, the content of polyacrylamide is more stringent, which needs to be 00005% or less. Polyacrylamide also includes the discharge of harmful waste gases and waste water, which may cause pollution to the environment. Therefore, when applying polyacrylamide to treat wastewater, it is necessary to pay attention to the dosage and product quality used, and take corresponding measures to minimize its impact on the environment.
In general, polyacrylamide itself is not toxic, but the monomeric acrylamide that may remain is toxic and may cause pollution to the environment. Therefore, during use, the dosage and treatment method must be strictly controlled to ensure that it will not cause harm to the human body and the environment.
