The growing demand for fertilizers worldwide associated with the government's call for production processes more friendly to the environment have led to the search for increasingly sustainable mechanisms of goods production, especially in relation to food. In this sense, the use of rural and urban organic wastes, which previously would be destined to landfills, soils and water bodies, in …
The soil microbial diversity acts in processes essential for the maintenance and functioning of the ecosystem. For global ecosystem functions, such as organic matter decomposition, nutrient cycling and assimilation of different carbon sources, the role of microbial diversity has been well studied. However, the same effect on the more specific functions (pesticide degradation), which are d…
The agricultural potential of Brazil is pointed out as a stimulating factor for the development of manufacturing agrochemicals, especially herbicides. Sugarcane is an important crop in the country occupying more than 8 millions of hectares. Recently, its harvest system is changing in order to not burn the crop straw, which generates 80-20 Mg ha-1 of surface residues. The maintenance of th…

The One Health concept emphasizes the interdependence between human health, ecosystem health, and animal health, recognizing the importance of soil, plants, and animals in this interconnection. Soil acts as a sink for contaminants, including potentially toxic elements (PTEs) and antibiotics, creating a favorable environment for the persistence of these compounds and the spread of antibiot…
Anthropogenic activities have led to contamination of soils with Potentially Toxic Elements (PTEs). Barium (Ba), for example, may accrue from the use of Barite (BaSO4) as a fluid in the drilling of oil wells. In flooded soils, obligate anaerobic microorganisms use sulfate as the final electron acceptors, reducing it to sulfide, thus making Ba available in the environment. Sulfate reductio…
Soil application of biochar results in agricultural and environmental advantages, improving soils physical-chemical attributes and mitigating greenhouse gases effects. However, biochar can directly interact with pesticides either neutralizing its efficacy or requiring higher application rates, which enhance environmental contamination risks. The interactions between biochar and pesticides…
Polycyclic aromatic hydrocarbons (HPAs) are organic pollutants with wide distribution resulting from incomplete combustion of organic matter, mainly by burning fuels such as oil and its derivatives. The great interest in studying the fate of these compounds is due to their toxicity and hematologic effects, mainly to its carcinogenic and genotoxic potentials. Generally, HPAs are removed fr…

Barium (Ba) has been widely used in oil drilling fluids in the barite form (BaSO4) due to its high density, low solubility and low toxicity. However, in anoxic soils, strictly anaerobic microorganisms use sulfate as the final electron acceptor reducing it to sulfide and making Ba available to the environment, posing a risk to human beings and plants. Manganese oxides are stronger oxidizin…
Biochar is amended to soils in order to improve their chemical, physical, and biological properties. This waste is a residue of bioenergy production, and therefore could be inserted into energy sustainability context, besides promoting carbon sequestration and greenhouse gases mitigation. However, biochar can sorb pre-emergent herbicides intentionally applied to soils, requiring higher ap…
Pesticides enter surface and ground waters through runoff from agricultural land and/or leaching through surface and subsurface soils. This project will address surface and subsurface features in glacial and tropical soils that control basic processes of sorption/desorption and bioavailability of herbicides in soils. Bioavailability is defined as the quantity of a chemical in soil or othe…
