Volatilization of agricultural chemicals is one process whereby chemicals may enter into parts of the environment where they were not intended. Starch encapsulation of pesticides has been proposed as a way of modifying pesticide behavior in the soil environment. This study was conducted to assess how starch encapsulation and temperature affect volatilization of atrazine [6.chloro-N-ethyI-N’-(l-...

10 The sorption behavior of the herbicides atrazine, alachlor and trifluralin on four sorbents (two 11 modified organoclays, one model sediment, and one natural sediment) in three water matrices 12 (synthetic water, natural groundwater and surface water) was investigated. The influence of 13 the sorbent and water matrix characteristics was elucidated. All adsorption isotherms fitted 14 well wit...

BACKGROUND The aim of the study was to obtain information on the residues of herbicides (imazametabenz, simazine, isoproturon, clortoluron, metribuzine, atrazine, cianazine, terbutrin, propanil, terbutilazine, alachlor and pendimetalin) present in water proceeding from Navarre. MATERIAL AND METHODS A total of 465 samples of water were taken: 378 were taken from 141 water supplies; the remaini...

Enrichment cultures containing atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) at a concentration of 100 ppm (0.46 mM) as a sole nitrogen source were obtained from soils exposed to repeated spills of atrazine, alachlor, and metolachlor. Bacterial growth occurred concomitantly with formation of metabolites from atrazine and subsequent biosynthesis of protein. When ring-labeled [...

Chloroacetanilide herbicides are widely used in the agricultural sector throughout world. Because of their poor biodegradability, high water solubility, and long persistence, chloroacetanilide have a potential to contaminate water, conventional treatment processes do not ensure sufficient removal. Therefore, heterogeneous photocatalysis using TiO2/UV-A was investigated for degradation alachlor,...
