Germicidal composition for water treatment

Germicidal composition for water treatment. Schwarzer, Hans (Peroxid-Chemie G.m.b.H., Ger.). Ger. Offen. DE 2629081 12 Jan 1978, 14 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C02B003-08. APPLICATION: DE 76-2629081 29 Jun 1976. DOCUMENT TYPE: Patent CA Section: 61 (Water) P-hydroxybenzoic acid, H2O2-resistant OH or CO2H derivs. of N heterocycles, and/or sulfamic acids or their salts or esters are germicides for synergistic use with H2O2 in disinfection of water. Thus 0.25 mL soln. of 35% H2O2 and 2% ammonium sulfamate (I) [7773-06-0] is added to 1 L culture soln. and incubated at 15°, resulting in formation of 2 ′ 104, <10, <10, and <10 bacterial colonies after 0, 1, 7, and 14 days, resp., compared with 2 ′ 105, 4 ′ 105, 3 ′ 107, and 5 ′ 105, resp., in the absence of H2O2, 5 ′ 104, 200, 50, and 500, resp., in the absence of I, and 7 ′ 104, 6 ′ 105, 5 ′ 106, and 2 ′ 106, resp., with no germicide.

Herbicidal pollution - pollen damage due to herbicides

Herbicidal pollution - pollen damage due to herbicides. Dubey, P. S. (Sch. Stud. Bot., Vikram Univ., Ujjain, India). Environ. Pollut., 13(3), 169-71 (English) 1977. CODEN: ENVPAF. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The germination rate of eggplant (Solanium melongena) exposed 24-48 h to vapors (100-1000 ppm) of 4 herbicides decreased similarly, but at 96 h exposure, 2,4-D (I) [94-75-7] was the most and ammonium sulfamate [7773-06-0] the least damaging. Damage from exposure to AC 92553 [40487-42-1] and Aresin [1746-81-2] increased to nearly 50% with an increase in concn. and duration of treatment.
