Amine antioxidants in water, ice, sediment and soil from the Songhua Wetland, Northeast China: Occurrence and fate.

Amine antioxidants (ANs) are emerging organic pollutants that are widely used in industrial products. The extensive use of ANs has polluted the environments. At present, there is no report on the pollution situation of ANs in wetland environment.

Screening and quantification of pesticides in wetland water, ice, sediment and soil: Occurrence, transport and risk assessment.

Current researches on pesticides in wetlands are limited in terms of screening and quantification of many types of pesticides. Understanding the spatial and temporal dynamics, distribution patterns, and environmental risks of pesticides in multiple media is important for wetland ecological conservation. In this study, 222 pesticides were determined in multimedia samples collected simultaneously from the Songhua Wetland during four seasons.
