Structure-toxicity of triaryl phosphates in freshwater algae

Structure-toxicity of triaryl phosphates in freshwater algae. Wong, P.Some chemicals with cas registry numbers like 78-30-8 and 78-32-0 are also used. T. S.; Chau, Y. K. (Natl. Water Res. Inst., Canada Cent. Inland Waters, Burlington, ON L7R 4A6, Can.). Sci. Total Environ., 32(2), 157-65 (English) 1984. CODEN: STENDL. ISSN: 0048-9697. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The effects of 6 triaryl phosphate compds. were tested on the primary productivity of pure algal cultures and natural phytoplankton in lake water. Substitution of the H atom by a Me group in the benzene ring decreased its effect. Tri-Ph phosphate [115-86-6] was the most toxic compd., followed by tolyl di-Ph phosphate [78-31-9], tri-o-tolyl phosphate [78-30-8] and trixylyl phosphate [25155-23-1]. The ortho isomer of tritolyl phosphate was more toxic than the meta- [563-04-2] and para- [78-32-0] isomers. Natural phytoplankton was more sensitive to triaryl phosphate compds. than the pure algal cultures. In addn. to the primary productivity, the reprodn. and nitrogenase [9013-04-1] activity of the algae were also reduced in the presence of tri-Ph phosphate. .

Agricultural films made of poly(vinyl chloride) type resins

Agricultural films made of poly(vinyl chloride) type resins. (Mitsubishi Monsanto Chemical Co., Japan). Jpn. Kokai Tokkyo Koho JP 58125737 A2 26 Jul 1983 Showa, 10 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L027-06; A01G009-14; C08K005-23; C08K005-51. 3147-76-0 and 85090-67-1 are cas registry numbers. These chemicals are also mentioned in this article. APPLICATION: JP 82-7122 20 Jan 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 19 Poly(vinyl chloride) (I) [9002-86-2] resins are mixed with trixylenyl phosphates (II) [25155-23-1] and 31 compd. selected from benzotriazoles (III, R = C4-18 alkyl) or bisbenzotriazoles (IV, R1 = C5-13 alkyl; R2 = C1-18 alkyl; X = H, halogen, alkyl, alkoxy, aryloxy, aralkoxy, or aryl), and then molded to give a title films having excellent weatherability. The films showed reduced bleeding of additives and degrdn. only after prolonged outdoor use. Thus, a resin contribution was prepd. from I (d.p. 1400) 100, dioctyl phthalate 45, epoxy resin EP-828 1, Ba-Zn liq. composite stabilizer 1.5, Ba stearate 0.2, Zn stearate 0.4, and sorbitan monostearate 1.5 part, and then was mixed with II [2,3-xylenyl + 3,5-xylenyl)/total xylenyl moieties = 0.1] 3 and 2-(2-hydroxy-5-tert-butylphenyl)benzotriazole [3147-76-0] 1 part to give a film 0.1-mm thick showing good weatherability. Addn. of bis(4-nonylphenyl) isophthalate [85090-67-1] to the above mixt. afforded films having excellent weatherability for a long time. .
