Diquat Dibromide Mitigation Proposal for Reduction of Human Exposure By
Diquat dibromide is used for desiccation of seed crops and potatoes, and for weed control of non-crop terrestrial and aquatic areas. The absorbed daily dosages for various work tasks were estimated in the exposure assessment document for diquat dibromide and range from 0.03 to 7.8 ug/kg/day. Based on the adjusted Estimated-No-Effect-Level (ENEL) of 33 ug/kg/day for developmental toxicity in rab...
متن کاملEffect of diquat (1,1'-ethylene-2,2'-dipyridylium dibromide) on the photosynthetic growth of Rhodospirillum rubrum.
Diquat (2 x 10(-4)m) inhibited both aerobic and anaerobic growth of Rhodospirillum rubrum. With photosynthetic cultures, diquat affected the synthesis of bacteriochlorophyll more readily than cell mass (turbidity). Diquat retarded the synthesis of bacteriochlorophyll and some protein more readily than that of other cellular constituents such as ribonucleic acid, deoxyribonucleic acid, and cell ...
متن کاملThe toxicity of diquat.
Clark, D. G. and Hurst, E. W. (1970). Brit. J. Industr. Med., 27, 51-55. The toxicity of diquat. The acute toxicity of diquat has been assessed in several species. The oral LD50 ranged from about 30 mg/kg in cattle to 231 mg/kg in the rat. Large doses of diquat gave rise to symptoms indicative of an action on the central nervous system, but smaller doses did not suggest an obvious mode of actio...
متن کاملFatal diquat intoxication.
BACKGROUND Since the introduction of diquat in agriculture practice in 1960's, about 40 cases of poisoning have been described in detail in medical literature. CASE REPORT We presented two cases. A case one, a 35-year-old, previously healthy, woman ingested 14% diquat solution. The poisoning had fulminant course, consisted of severe stomachache, vomiting, cardiocirculatory shock, respiratory ...
متن کامل3-(Ammoniomethyl)pyridinium dibromide
In the title salt, C(6)H(10)N(2) (2+)·2Br(-), the non-H atoms of the 3-methyl-pyridinium unit of the cation are almost coplanar (r.m.s. deviation = 0.0052 Å). In the crystal, the dications and Br anions are linked by a combination of six hydrogen bonds, viz. one N(py)-H⋯Br, two C-H⋯Br and three H(2)N-H⋯Br, into supra-molecular layers, parallel to the bc plane, composed of alternating R(2) (4)(1...
