Primary study on nitrate pollution of rice grain in kafr El-Sheikh Governorate
Abstract: Rice is one of the most important food and export crops of Egypt. Kafr El-Sheikh Governorate is an important site of the six Governorates producing the rice in Egypt. Nitrate pollution in food crops gets high attention and efforts from the researchers because it causes health and economic damage.
The objective of the present study is finding the answer of the following question:
Are there nitrate pollution in the rice grain produced in Kafr El-Sheikh Governorate?
Four randomly rice grain samples from different fields replicated with four common varieties from every district of the ten districts of Kafr El-Sheikh Governorate in the two successive summer seasons of 2001 and 2002 were collected. This is equal to 320 samples (4 replication x 4 varieties x 10 districts x 2 seasons).
The samples were air dried, grinded and nitrate was extracted by acetic acid 2%. Nitrate was measured by colorimetric method.
Data show that the nitrate content of the rice grain of the studied varieties (Sakha 101, Sakha 102, Giza 177 and Giza 178) was less than the destructive level.
No clear correlation between the varities and the nitrate content.
Kafr El-Sheikh district had the highest average of rice nitrate content (10.1) g g-1, while Qualeen had the lowest average of nitrate content (3.5) µg g-1
