Glyphosate and atrazine in rainfall and soils in agroproductive areas of the pampas region in Argentina
Abstract: The presence in the atmosphere of glyphosate (GLP) and atrazine (ATZ) was investigated—those pesticides dominating the market in Argentina—through rain, as the main climatic phenomenon associated with wet deposition, both through analyzing source-receptor relationships with soil along with the climatic influences that may condition that transport and through estimating the annual deposition on the surface …
Glyphosate and AMPA concentrations in wind‐blown material under field conditions
Abstract: Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle‐farming country, which has increased its productivity in the last few decades, widening the boundaries of farm land and the use of herbicides to control weeds. Glyphosate, which accounts for …
Recent and projected increases in atmospheric CO2 concentration can enhance gene flow between wild and genetically altered rice (Oryza sativa)
Abstract: Although recent and projected increases in atmospheric carbon dioxide can alter plant phenological development, these changes have not been quantified in terms of floral outcrossing rates or gene transfer. Could differential phenological development in response to rising CO2 between genetically modified crops and wild, weedy relatives increase the spread of novel genes, potentially altering …
From silent spring to silent night: Agrochemicals and the anthropocene
Abstract: We are now living in the Anthropocene, the first time in Earth’s history when synthetic chemicals—created by humans—are damaging the planet and contributing to a major loss of biodiversity. Pesticides are a particular problem in this regard. Agricultural practices changed dramatically following World War II. Methods for the production of nitrogen for manufacturing explosives …
