Is air pollution exposure linked to household income? Spatial analysis of Community Multiscale Air Quality Model results for Madrid.

This study explores the potential correlation between income and exposure to air pollution for the city of Madrid, Spain and its neighboring municipalities. Madrid is a well-known European air pollution hotspot with a high mortality burden attributable to nitrogen dioxide (NO) and fine particulate matter (PM). Statistical analyses were carried out using electoral district level data on gross household income (GHI), and NO and PM concentrations in air obtained from a mesoscale air quality model for the study area.

Quantitative PCR (qPCR) for estimating the presence of and its mycotoxins in barley grains.

Members within the species complex (FSAMSC) are able to produce mycotoxins, such as deoxynivalenol (DON), nivalenol (NIV), zearalenone (ZEN) and enniatins (ENNs) in food products. Consequently, alternative methods for assessing the levels of these mycotoxins are relevant for quick decision-making. In this context, qPCR based on key mycotoxin biosynthetic genes could aid in determining the toxigenic fungal biomass, and could therefore infer mycotoxin content.

Rapid assessment of enniatins in barley grains using near infrared spectroscopy and chemometric tools.

Barley is an important crop worldwide, and it can be affected by various fungi, among them Fusarium is one of the most relevant due to the economic losses caused by mycotoxin contamination. Enniantins (ENNs) are one of the emergent group of mycotoxins that have been found in grains around the world. Nowadays, the main analytical tools available to evaluate these contaminants are based on chromatographic techniques that are efficient but time-consuming and expensive.

Survey of Freshly Harvested Oat Grains from Southern Brazil Reveals High Incidence of Type B Trichothecenes and Associated Species.

The current study investigated the fungal diversity in freshly harvested oat samples from the two largest production regions in Brazil, Paraná (PR) and Rio Grande do Sul (RS), focusing primarily on the genus and the presence of type B trichothecenes. The majority of the isolates belonged to the species complex, and were identified as sensu stricto (s.s.

Near infrared spectroscopy and smartphone-based imaging as fast alternatives for the evaluation of the bioactive potential of freeze-dried açai.

The development of green analytical techniques for food industry quality control has become an important issue in the context of the fourth industrial revolution. In this sense, near infrared spectroscopy (NIR) and smartphone-based imaging (SBI) were applied to evaluate the bioactive potential of freeze-dried açai pulps. For this purpose, reference results of ninety-six samples were obtained by determining total anthocyanins (TAC), polyphenol content (TPC), and antioxidant capacity (DPPH, ORAC and TEAC) by traditional methods and correlated to NIR spectra and SBI to build predictive models based on partial square least (PLS) regression.
