- Abstract
The transportation pathways of triazines were investigated from their origins onwards, in the Marne and the Seine rivers (France). According to the 1991 survey, the highest total triazine concentration levels (956 ng L-1) were found in the river Marne: 580 ng L-1 for atrazine and 200 ng L-1 for simazine, in relation with agricultural practices. The total triazine levels reached 829 ng L-1 in the river Seine. The other triazines remained low, from 5 to 75 ng L-1. The triazine fluxes were 226 and 404 kg for a 118 d period in the Marne and the Seine rivers, respectively. Out of the treatment period, triazine peaks were related to river flows with a 48 hr delay between the peak and the top of the flood. After herbicide treatment, peak concentrations were closely related with the precipitations. Concerning the river Marne tributaries, highest atrazine concentrations were found in June, in those which drained the vineyard area. In January, the concentrations were higher in periurban areas underlining their contribution to the herbicide inputs in the rivers. On the whole, the ratio of triazines transported in the two rivers represented 0.2% of the total amount applicated annually on their catchment basins.
