- Title:
- Investigation of the Amount of Agricultural Chemical Residues in Cottonseed Oil
- 摘要:
- 本文应用同位素示踪法研究35S—1059在棉籽油中的残留情况。试验结果：1.1059虽是内吸剂，在炎夏用其涂叶，则棉叶吸收量仅占用量的27%左右。这些进入棉叶的1059在现蕾期能逐步往茎等部位运转。但在盛花期则大多停留在叶片内，不再转向其他部位。因此，从1059在棉株内动态分布来看，棉籽油内的残留量是极为有限的。2.当用低本底计数装置测定棉籽油中的示踪量时，发现其放射性强度均接近本底值（1.1 cmp）。但在棉仁渣内测出的示踪1059量约为0.1—0.2ppm，且其量随着用药次数的增
- Abstract:
- Cottonseed oil is the major edible oil in cotton-producing area.In recent years,the use of agricultural chemicals has been increasing.The amount of chemical residues in cottonseed,therefore,oil is a problem concerning people’s health.We investigated the remaining of 35SS-1059 in cottonseed oil by tracer method in 1974. 1.Although 1059 could be absorbed by plants,when applied to cotton leaves in summer,only about 27% of it was absorbed.The 1059 absorbed in cotton leaves could be gradually transported to the twiges or other plant organisms during the buding period.But most of it remained within the leaves during forescence.Thereforce,judging from their dynamic distribution of 1059 in whole cotton tree,we conclude that its residues in the cottonseed oil is very little. 2.When useing low background counting equipment to measure the amount of tracer in cottonseed oil,we found that its radioactive intensity was close to the backgrunod number (1.1cpm).We also found that there was almost 0.1-0.2ppm 1059 added with tracer in the oil free cottonseed residues,and the amount of 1059 added with tracer increased along with the increase of applications of the chemical. The amour of 1059 remaining in both cottonseed oil and oil-free residues is under the level permitted by the national standards.
