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...

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...

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...

Multipurpose fluorescent nanocarriers: environmental behavior, toxicity and int...

Engineered nanomaterials, such as silica mesoporous nanocapsules (SiNC), have emerged as a powerful tool for the controlled delivery and release of active compounds in various fields. However, the environmental impact of SiNC on marine biota, particularly when they enter the marine environment through wastewater effluents or direct release from maritime coatings, re-mains poorly understood. Studying their effec...

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...

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...

A study of wastewater disinfection with photodynamic treatment and its ecotoxic...

Viruses have higher mutation rates when compared with other microorganisms, particularly RNA viruses [1]. The higher mutation rate promotes the development of resistance to traditional antivirals, establishing a resistance behavior in viruses populations [1]. RNA viruses in wastewater (WW) have already been reported, leading to potential public health risks [2]. Wastewater treated with conventional antimicrobia...

Ecotoxicological effects of fluvial eroded bitumen sediments from the Alberta o...

To fully understand the ecological and cumulative effects of mining activities on the surrounding aquatic systems of the Canadian oil sands region, it is essential to understand the consequences of exposure to bitumen-containing soils/sediment from natural geomorphological processes. Both physical and chemical stress on aquatic biota can potentially result from exposure to natural bitumen, resulting from hillsl...
