1. Erros judiciários em tempos de digital surveillance: os algoritmos de reconhecimento facial em questão
Resumo The overall complexity of the subject matter and the required high level of expertise make environmental crime investigations quite a challenging task for law enforcement. The clandestine nature of environmental offences combined with the environmental law’s intricacy is among the reasons behind prosecutorial failures. The authors analyze a criminal

2. Evaluation of sediment contamination by urban sewage in a stretch of Capibaribe River, Pernambuco, Brazil
Anthropic activities are responsible for the increase in environmental contamination, especially in aquatic systems, demanding studies to assess and monitor contamination levels in different water bodies. We have done a chemical characterization of eleven sediments in order to evaluate the level of contamination by domestic sewage from the Capibaribe River,

3. A Systematic Pipeline to Enhance the Fecal Metabolome Coverage by LC-HRMS
The comprehended knowledge of the metabolic profile of the fecal matter has been recognized as an important point for understanding metabolic changes in the human systemic metabolism and it can provide precious information about host-gut microbiota interactions. However, few analytical strategies have been addressed for a broad analysis of metabolites with d

4. Avaliação da concentração e composição inorgânica do material particulado coletado no estado do Rio de Janeiro
Cities urbanization and modernization increase emission sources, contributing to particulate matter (PM) composition heterogeneity and enhance the risk to human health and environment. This paper intends to survey the studies on particulate matter carried out in the state of Rio de Janeiro. The sampling of PM is generally made using Hi-Vol samplers to collec

5. Organic Matter Leached from Tropical Soils by Simulated Rain, Hard (NaOH) and Soft (NaNO3) Extractions: A Realistic Study about Risk Assessment in Soils
Alkaline extractions from humic material are used to risk assessment in soils. However, there are questions about the type of extraction most suitable for this evaluation. Thus, this work evaluated different soil extractions in search of realistic environmental conditions (simulated rain). The parameters obtained revealed significant differences between the

6. Interaction of Suspended Particulate Material with Cd2+ and Pb2+ in a Brazilian Lagoon Estuarine System
The suspended particulate material (SPM) present in waters has fundamental importance for a better understanding of environmental behaviors of aquatic pollutants. This work determined the physicochemical parameters (pH, temperature, conductivity, total organic carbon and metals concentration) in water samples from Mundaú-Manguaba estuarine-lagoon system, Al

7. Bromatological aspects of Lentinus crinitus mushroom (Basidiomycota: Polyporaceae) in agroforestry in the Cerrado
Abstract Much of the diversity of mushrooms is still unknown to science. In the search for new edible mushrooms, we began to look at the traditions of Amazonian forest peoples in order to learn about the potential for edible mushrooms among other species. In particular, the Yanomami people launched the encyclopedia of food (Sanoma) in 2016 to preserve their

8. Integrated use of sewage sludge and basalt mine waste as soil substitute for environmental restoration
Abstract If not managed properly, mining waste can be detrimental to the environment. In addition, sewage treatment plants produce sludge, a biowaste rich in organic matter which is often sent to landfills. The present study evaluated the use of sewage sludge as an amendment for mine waste from a basalt quarry as an alternative to the use of soil from borrow

9. Occurrence of Pesticides Associated to Atmospheric Aerosols: Hazard and Cancer Risk Assessments
Since the 1950s, pesticides have been used in agriculture. The increase in their consumption has been observed in recent years. In this work, it was determined the concentration of pesticides in the atmosphere of São Paulo and Piracicaba cities (sugarcane plantation site) and the hazard quotients and cancer risk caused by inhalation of these compounds were

10. Emissões de poluentes atmosféricos em condições reais de pavimentação asfáltica: material particulado, black carbon e hidrocarbonetos policíclicos aromáticos
Intensive use of asphalt generates pollutants into the atmosphere which are harmful to the environment and worrying for occupational health. The application of asphalt products leads to emissions of significant concentrations of polycyclic aromatic hydrocarbons (PAHs) and particulate matter (PM) to the atmosphere. This paper aims to assess the pollutant emis
