Abstract： Nitrosamine compoundsare widelydistributedandhavesignificantcarcinogenicity，posingamajorthreattothe ecological environmentand human health.Inordertoaddressthechallenges ofmonitoringandcontrolling nitrosamines in water environments，asystematic monitoring network is establishedand long-term observations are conducted，combined with gas chromatography-mass spectrometry detection technology，the spatiotemporal distribution characteristics and influencing factorsof ninetypical nitrosamines in water are studied，andcontrol strategies basedonchemicaloxidation and biodegradationare proposed.Research has found thattheconcentrationof nitrosamines in waterexhibitssignificant seasonal variations with factors such as temperature，pH value，and organic matercontent.Theexperimental results show thatheoptimized control method canachieveanitrosamineremoval rateofover 95%，providing reliable technical support for environmental engineering practice.
