Hazard identification and characterization of leachable chemicals from plastic ...

A recent study has suggested that plastics may contain more than 16,000 chemicals, including additives, processing aids, starting substances, intermediates and Non-Intentionally Added Substances. Plastic chemicals are released throughout the plastic life cycle, from production, use, disposal and recycling. Most of these chemicals have not been studied for potential hazardous properties for humans and in the env...

Towards safer edible insects: assessing contaminant bioaccumulation and depurat...

The integration of insects into sustainable food and feed chains demands a robust evaluation of their capacity to accumulate and eliminate contaminants. Understanding these dynamics is fundamental to ensuring consumer safety and supporting the development of regulatory standards for insect-derived products. This study assessed the bioaccumulation and depuration kinetics of metal(loid)s (As, Cd, Pb) and mycotoxi...

Obstetric violence assessment scale: development and validation

Introdução: A violência obstétrica tem sido alvo de debate entre os profissionais de saúde e nos meios de comunicação social. Objetivo: Desenvolver e validar um instrumento para medir a perceção de violência obstétrica que as mulheres têm da experiência de trabalho de parto e parto. Métodos: Com base nas recomendações da WHO, elaborou-se uma escala composta por 38 afirmações. A avaliação das propriedades métric...

A comprehensive ecotoxicological evaluation of a treated olive mill wastewater ...

Olive mill wastewaters (OMWWs) are an environmental problem in the Mediterranean region, and it is crucial to explore strategies for their treatment and repurposing. The chemical precipitation technique (CPT) has been presented as a cost-effective wastewater treatment solution that might be applied to OMWW. The CPT-resulting precipitant subproducts (sludge) may be reprocessed (e.g., agricultural fertilizer and/...

Exploring BPA alternatives - Environmental levels and toxicity review

Bisphenol A alternatives are manufactured as potentially less harmful substitutes of bisphenol A (BPA) that offer similar functionality. These alternatives are already in the market, entering the environment and thus raising ecological concerns. However, it can be expected that levels of BPA alternatives will dominate in the future, they are limited information on their environmental safety. The EU PARC project...

Structural and functional shifts in the microbial community of a heavy metal-co...

The interplay between metal contamination and climate change may exacerbate the negative impact on the soil microbiome and, consequently, on soil health and ecosystem services. We assessed the response of the microbial community of a heavy metal-contaminated soil when exposed to short-term (48 h) variations in air temperature, soil humidity or ultraviolet (UV) radiation in the absence and presence of Enchytraeu...

Wastewater disinfection with photodynamic treatment and evaluation of its ecoto...

Research has demonstrated the presence of viruses in wastewater (WW), which can remain viable for a long period, posing potential health risks. Conventional WW treatment methods involving UV light, chlorine and ozone efficiently reduce microbial concentrations, however, they produce hazardous byproducts and microbial resistance that are detrimental to human health and the ecosystem. Hence, there is a need for n...

Assessing Contaminant Uptake and Elimination in Insects: Implications for Susta...

Considering the global food crisis and the pressing issue of waste generation, sustainable solutions for food demand are crucial. Insects have emerged as a promising protein source for food and feed due to their efficient bioconversion capacity and ability to utilize nonvaluable products. However, ensuring the safety of insects for food and feed is essential. This study aims to comprehensively evaluate the upta...
