The soil environment quality of investigating area accords with NY/T 391-2000 Environmental technical terms for green food production area, 75% of the soil samples accord with NY 5199-2002 Environmental terms for organic tea production area standard,BHC and DDT aren’t detected in these soil samples, Environment quality of tea production area is very good. By detecting BHC, DDT, Cu, Pb in the tea samples, estimating with NY 5017―2001 No social effects of pollution food Tea standard, 0 % of fresh tea samples doesn’t accord with the standard, 11% offinished product tea samples doesn’t accord with the standard, the pollutant is Cu. Estimating with NY 5196―2002 organic tea standard, 95.2% of fresh tea samples doesn’t accord with the standard, the pollutants are BHC and Pb in the tea samples, percentage of the tea samples which BHC is detected out in is 95.2, percentage of the tea samples which content of Pb doesn’t accord with the standard is 9.5. 100% offinished product tea samples doesn’t accord with the standard, percentage of the tea samples which BHC is detected out in is 89, percentage of the tea samples which content of Cu doesn’t accord with the standard in is 61, percentage of the tea samples which content of Pb don’t accord with the standard in is 50. Pesticide irrationality use in production is the main cause of BHC being detected out in finished product tea samples; uncleanness machining is the main cause of content of Cu and Pb being not according with the standard in finished product tea samples.
