In this work we studied the effect of cadmium (Cd) (25 μM), in spinach plants (Spinace oleracea) growing in nutrient solution, for 1, 2 and 7 days. Spinach growing in the contaminated solution showed a decrease in biomass, chlorophyll content and an increase in malondialdehyde (MDA) content, showing that photosynthetic apparatus was affected and li...

Cadmium is a highly soluble element with no known biological function, and can be toxic to plants even at low concentrations. The importance of knowing plant uptake mechanisms and response to oxidative stress is related to their potential use in phytoremediation processes and also, in the case of food crops, to the possible contamination of the foo...

Potentially toxic elements (PTE), like heavy metals, certain metalloids and some salts, can affect plant development and production yields of food crops. The stress induced by these PTE is a worldwide problem due to the increased soil and water pollution. Basil (Ocimum basilicum) is a culinary herb that has been increasingly used in modern cuisine....

Several species from the Brassica genus are very important agricultural crops in different parts of the world and are also known to be heavy metal accumulators. There have been a large number of studies regarding the tolerance, uptake and defense mechanism in several of these species, notably Brassica juncea and B. napus, against the stress induced...

The interest in seaweeds as an abundant feedstock to obtain valuable and multitarget bioactive ingredients is continuously growing. In this work, we explore the potential of Gracilaria gracilis, an edible red seaweed cultivated worldwide for its commercial interest as a source of agar and other ingredients for cosmetic, pharmacological, food, and f...

The most consumed fish species in Portugal do not correspond to the most caught fish species on the Portuguese coast. From the point of view of ocean sustainability and economics, it is important to study unexploited or underexploited fish species that have the potential to be introduced into the food market. This potential can be reflected by thei...

Target species diversification is essential for fisheries sustainability and fish market revitalization. Fish discards are a widely recognized problem resulting from fisher-ies worldwide, and are of major concern for all sector players, from administrations, to fishermen, and scientists. However, non-target species are seldom studied, and informati...

This chapter gives a good grounding in view of the development of innovative technological solutions that enhance the valorisation and efficient use of marine resources through the integration of value chains, in a logic of circular economy, articulating food industry, biotechnology, and fisheries. Economy is a business model that extends the circu...

We live in a world of limited biological resources and ecosystems, which are essential to feed people. Consequently, diversifying target species and considering full exploitation are essential for fishery sustainability. The present study focuses on the valorization of three low commercial value fish species (blue jack mackerel, Trachurus picturatu...

Overfishing is increasing over time, and according to FAO (Food and Agriculture Organization), about one third of the world’s fish stocks are now overfished. Thus, diversifying the target species is essential for fisheries sustainability contributing to improve resource-efficient processes. Non-target species can be valuable resources for the devel...

Fish is a very perishable food and therefore several storage strategies need to be employed to increase its shelf-life, guaranteeing its safety and quality from catch to consumption. Despite the advances in modern fish storage technologies, chilling and freezing are still the most common preservation methods used onboard. The present review aims to...

Storing non‐marketable fish aboard fishing vessels takes up valuable storage space and, consequently, it is usually discarded. Therefore, the strategy to minimize the amount of discarded fish and boost the fishing economy should entail measures to turn unexploited species into marketable fish. The use of sensory descriptive analysis is usually the...

In this work the effect of the addition of different amounts of cattle slurry (CS) to a Cd contaminated soil, was studied regarding its effect in spinach plants. Two levels of Cd contamination (2 and 10 mg/kg) and three levels of CS addition were evaluated (2.5, 5 and 10 g CS/100 g soil). Spinach was shown to be a tolerant species, able to accumula...

Honey has been used as food since prehistoric times. Nowadays honey is consumed on a large scale all over the world, playing an important role in the human diet, and is also used in the food, pharmaceutical and cosmetic industries. There has been growing public concern about adverse reactions caused by some foods, such as pollen, and perhaps this i...

A crescente preocupação com o ambiente e a sua proteção leva à necessidade de desenvolver capacidades, comportamentos e atitudes necessárias para que as relações de interdependência Homem – Ambiente possam vir a ser melhoradas. Uma das estratégias é a educação ambiental estar presente nos mais jovens, não só por virem a ser os futuros adultos como...

A água é um bem indispensável à vida, que por ser um bom solvente pode facilmente ser contaminada. Desta forma, a sua contaminação e má gestão devido ao rápido desenvolvimento económico, à industrialização e ao crescimento demográfico, tem-se tornado num tema problemático a nível mundial. Esta atividade foi desenvolvida no âmbito da unidade curricu...

O acesso à Educação é um direito de todas as crianças. Pretende-se que a Educação seja holística e integradora, promova a igualdade social, permitindo aceitar e respeitar a diferença. A sala de aula constitui um contexto privilegiado de socialização, um espaço formal de desenvolvimento onde o aluno interage com situações do seu quotidiano, facilita...

A promoção da literacia científica no 1º Ciclo do Ensino Básico permite aliar o desenvolvimento de competências científicas e sociais. Considerando as dificuldades do grupo em estudo (26 alunos do 4ºano), em estabelecer relações e a inexistência de atividades em ciências na sua rotina, delineou-se um plano de ação que contribuísse para a promoção d...

Response of spinach (Spinacea oleracea L.) to cadmium-induced oxidative stress The contamination of edible vegetables is a worldwide problem due to the increase of soil and water pollution. Cadmium is a toxic metal that can be easily taken up by plants from soils or irrigation water due to its high solubility and consequently high bioavailability....

Spinach (Spinacea oleracea L.) is a leafy vegetal highly cultivated and appreciated worldwide. Plant contamination by toxic metals can be a problem when plants are tolerant and can cope and even thrive with high metal contents and can accumulate toxic metals in parts consumed by animals and humans. Tolerant plants can develop physiological changes...

The contamination of edible vegetables by toxic metals is a problem that derives from using contaminated soils or irrigation water. Experiments were conducted to study the stress response induced by cadmium in Spinacea oleracea. Spinach plants were grown in nutrient solution with 25 μM and 50 μM Cd for 7 days. Several physiological parameters were...

Fish consumption is very important, it is a source for essential elements in human diet, never the less, bioaccumulation may to make fish toxic. This study is quantification in the concentration of nine essential elements (K, Ca, Cl, S, Fe, Cu, Zn, Se, As), two toxic elements (Cd, Pb) and one other element (Br) in seventy five different muscle samp...
