A hazardous chemical, N-Methyl-2-pyrrolidone (NMP), known to cause developmental harm, has been detected in a reservoir located near an industrial park in Komárom, Hungary. The discovery was reported by Greenpeace, who alerted local authorities. The environmental group suspects the chemical contamination may be linked to nearby battery manufacturing plants operating in the area. An investigation has been launched to determine the source of the NMP and assess the extent of the pollution. NMP is a solvent used in lithium-ion battery production, raising concerns about industrial discharge. Authorities are working to ascertain if the battery factories are responsible for the presence of the harmful substance in the water supply. The findings could lead to stricter environmental regulations for the industry.
