Microplastics in Santos São Vicente estuarine - Hotspot in sediments caused by low energy hydrodynamic events in strongly populated areas.

Microplastics (MPs) have emerged as a significant class of contaminants due to their widespread presence in various environmental compartments. The ingestion of these particles poses a risk to both human health and the local biota. The investigation of the Santos estuary reveals the abundance of microplastics in the mangrove sediment.

Potentially Toxic Elements in Urban-Grown Lettuce: Effectiveness of Washing Procedures, Risk Assessment, and Isotopic Fingerprint.

This study investigates the presence of potentially toxic elements (PTEs) in lettuce ( L.) grown in urban gardens in a highly industrialized city in Brazil and evaluates the effectiveness of different washing methods in reducing contamination. Ten elements (arsenic (As), barium (Ba), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), vanadium (V), and zinc (Zn)) were analyzed for their concentration, and a health risk assessment was performed.

Impact of BCG Vaccination Disruptions During the COVID-19 Pandemic on Tuberculosis Incidence in Infants: A Nationwide Study in Brazil.

Pandemic-related disruptions led to lower Bacille Calmette-Guérin (BCG) vaccine coverage in Brazil. This study highlights a link between reduced vaccinations and increased tuberculosis pulmonary and extrapulmonary cases in infants. Addressing vaccine hesitancy and ensuring healthcare stability is vital for mitigating impacts.
