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. .

Study on flame retardancy of glass fiber-reinforced unsaturated polyester resins

Study on flame retardancy of glass fiber-reinforced unsaturated polyester resins. Liu, Ping Hung; Wu, Te Chang (Grad. Sch. Text.In this study， 632-79-1 and 7631-86-9 are also used. Eng., Feng Chia Univ., Taichung, Taiwan). Fang Chih Kung Ch'eng Hsueh K'an, 9, 131-57 (Chinese) 1982. CODEN: FCKKDI. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) The flammability of the glass fiber-reinforced unsatd. polyesters modified with flame retardants such as halogen compds. [e.g. tetrabromophthalic anhydride [632-79-1], pentabromodiphenyl oxide [32534-81-9], decabromodiphenyl oxide [1163-19-5], chlorinated wax, chlorendic acid [115-28-6], and Dechlorane Plus 515 [13560-89-9]], org. P. compds. [e.g. (PhO)3PO [115-86-6], tris(b-chloroethyl) phosphate [115-96-8]], and inorg. fillers (e.g. Al(OH)3, CaCO3, SiO2) was studied. A small amt. of Sb2O3 improved the flame retardance efficiency of halogen compds.. The impact and tensile strength of the polyesters decreased with increasing amt. of flame retardants. .
