"Both the draft environmental and human health risk assessments identified risks from the use of acrylamide and n-methylolacrylamide (NMA) grouts. Risks to the environment are to aquatic organisms following use that is not ‘normal’ ... Risks to human health are confined to workers under conditions of ‘normal’ use in large-scale operations where these grouts are applied. There are also considerable risks to workers following mis-applications." (Quoted from paper)
