Seasonal variation and factors influencing perchlorate in water, snow, soil and corns in Northeastern China
چکیده انگلیسی

Seasonal variation and influencing factors of perchlorate in snow, surface soil, rain, surface water, groundwater and corn were studied. Seven hundreds and seventy samples were collected in different periods in Harbin and its vicinity, China. Perchlorate concentrations were analyzed by ion chromatography–electrospray mass spectrometry. Results indicate that fireworks and firecrackers display from the Spring Festival to the Lantern Festival (February 2, 2011–February 17, 2011) can result in the occurrence of perchlorate in surface soil and snow. Perchlorate distribution is affected by wind direction in winter. Melting snow which contained perchlorate can dissolve perchlorate in surface soil, and then perchlorate can percolate into groundwater so that perchlorate concentrations in groundwater increased in spring. Perchlorate concentrations in groundwater and surface water decrease after rainy season in summer. Groundwater samples collected in the floodplain areas of the Songhua River and the Ashi River contained higher perchlorate concentrations than that far away with the rivers. The corns have the ability to accumulate perchlorate.


► Perchlorate in snow and surface soil comes mainly from fireworks and firecrackers display.
► Perchlorate was dissolved by melting snow and then permeated into groundwater.
► Perchlorate in surface water comes mainly from sewage draining exit along the rivers.
► Corn has the ability to accumulate perchlorate from groundwater.
