The impact of child poverty on brain development: does money matter?

The development of the human nervous system makes up a series of fundamental and interdependent events involving birth, growth, and neuronal maturation, in addition to the positive or negative selection of synapses of these neurons that will participate in the composition of neural circuits essential to the activity of the nervous system. In this context, where environment and social relationships seem to be relevant markers for neurodevelopment, advanced neuroimaging techniques and behavioral assessment tools have demonstrated alterations in brain regions and cognitive functions among children developing in low or high socioeconomic status environments. Considering the aspects mentioned, this review aimed to identify the importance of socioeconomic status in children's brain development, seeking to identify what are the impacts of these factors on the morphological and physiological formation of the nervous system, allowing a greater understanding of the importance of environmental factors in neurodevelopmental processes.

Removal of mercury by silica-supported ionic liquids: Efficiency and ecotoxicological assessment.

Anthropogenic impacts have affected the coastal environment and contributed to its contamination. Mercury (Hg) is widespread in nature and has been shown to be toxic in even the smallest amounts, negatively affecting not only the marine ecosystem but also the entire trophic chain due to its biomagnification. Mercury ranks third on the Agency for Toxic Substances and Diseases Registry (ATSDR) priority list and it is therefore imperative to develop more effective methods than those currently available to avoid the persistence of this contaminant in aquatic ecosystems.

Ingesting microplastics or nanometals during development harms the tropical pollinator Partamona helleri (Apinae: Meliponini).

The disposal of plastics and metal-derived compounds results in the contamination of the environment with nano/microparticles, leading to the exposure of various organisms to these harmful particles. However, the impacts of these particles on pollinating insects, which provide relevant ecosystem services, are not well understood. The aim of this study was to assess the effects of microscopic particles on the tropical pollinator Partamona helleri (Apinae: Meliponini), specifically evaluating the toxicity of plastic microparticles (polystyrene - PS, and polyethylene terephthalate - PET) and nanoparticles of a metal oxide (titanium dioxide - TiO) via larval ingestion by bees reared in vitro.

Bioinsecticide spinosad poses multiple harmful effects on foragers of Apis mellifera.
