Regional nitrate and pesticide trends in ground water in the eastern San Joaquin Valley, California.
Protection of ground water for present and future use requires monitoring and understanding of the mechanisms controlling long-term quality of ground water. In this study, spatial and temporal trends in concentrations of nitrate and pesticides in ground water in the eastern San Joaquin Valley, California, were evaluated to determine the long-term effects of agricultural and urban development on...
BACKGROUND Residential proximity to agricultural pesticide applications has been used as a surrogate for exposure in epidemiologic studies, although little is known about the relationship with levels of pesticides in homes. OBJECTIVE We identified determinants of concentrations of agricultural pesticides in dust. METHODS We collected samples of carpet dust and mapped crops within 1,250 m of...
Several recent studies have focused on leaching pesticides from agricultural soils into surface and groundwater resources during irrigation. As a result, information about herbicide residues in water was necessary for conserving related resources. This study provided an overview of monitoring herbicides worldwide. In this scoping review, five databases were searched publications (1990 to April ...
The present study evaluates the removal capacity of microalgae photobioreactors environmental pollutants in wastewater from dry riverbed El Albujón, as a way to minimize eutrophication process Mar Menor. Particularly, four autochthonous consortia collected different locations salty lagoon remove emerging contaminants (simazine, atrazine, terbuthylazine, adenosine and ibuprofen), nitrates, phosp...
In this paper, the Langmuir-Freundlich isotherm is used to model the interaction of several triazines (desethylatrazine, desisopropylatrazine, simazine, atrazine, propazine and prometryn) with a propazine-imprinted polymer and to explain the observed cross-reactivity. Different rebinding experiments (each herbicide alone or all together in a mixture) were carried out and the experimental bindin...
