Abstract

Response of weed species Ambrosia artemisiifolia L. on herbicide residues presence in irrigation water.

Abstract

The samples for water analyses were taken from the Danube Tisa Danube canal from the locality Vrbas (45°34′10″N/19°38′16″E). A multi-residue method was used for the determination of twenty-one herbicides and the products of their transformation with isoproturon-d6 and atrazine-d5 as internal standards in surface water using liquid chromatography tandem-mass spectrometry (LC-MS/MS) with ESI. Metamitron, terbuthylazine, atrazine, prometryn and metolachlor as well as terbuthylazine-desethyl (metabolite of terbutilazine) were detected. Ambrosia artemisiifolia L., invasive weed species, was grown in the laboratory, controlled conditions. For its irrigation canal water collected during May, June and July was used. Control was irrigated with distilled water. The content of photosynthetic pigments (chlorophylls a, b and carotenoids) and phenolic compounds as a response to irrigation with polluted water, was determined.
