“…Estudos recentes sobre a espécie mencionam a influência dos fatores ambientais sobre assembleia de peixes demersais, indicando que a abundância da espécie C. spilopterus está relacionada a gradientes eurialinos ou áreas de maior salinidade (Cardoso et al, 2023). Da mesma forma, Castilhos et al (2019) mencionam que esta espécie é menos susceptível à contaminação por metais pesados que outras espécies, porém a contaminação afeta o metabolismo. Assim também, Kobelkowsky e Castillo-Rivera (2018) estudaram a anatomia sexual de machos e fêmeas da espécie destacando as diferenças com espécies de outras famílias.…”

O estudo objetivou descrever traços da história de vida, tais como a estrutura populacional, idade, crescimento, mortalidade e a biologia reprodutiva do linguado Citharichthys spilopterus, em um estuário subtropical no sul do Brasil. Foram capturados 275 exemplares obtendo dados de peso total, comprimento total, amostras teciduais e peso das gônadas. Os resultados evidenciaram cinco estádios de desenvolvimento gonadal e desova parcelada, com picos reprodutivos em outubro e março. O comprimento da primeira maturação foi de 10,1 cm para fêmeas e 8,0 cm para machos, com crescimento do tipo alométrico positivo. O comprimento máximo teórico foi de 17,9 e 15,5 cm, coeficiente de crescimento de 0,43 e 0,68 ano-1 e longevidade de 5,9 e 4,4 anos, para fêmeas e machos respetivamente. Predominaram os indivíduos adultos em todos os meses de coleta, exceto no mês de maio. A mortalidade total foi de 1,35 e 2,39 ano-1, a mortalidade natural de 1,07 e 1,5 ano-1 e a mortalidade por pesca de 0,28 e 0,89 ano-1, para fêmeas e machos respetivamente. A taxa de exploração obtida foi de 0,21 e 0,37ano-1, para fêmeas e machos respetivamente, permitindo inferir que a espécie se encontra em situação de exploração adequada em relação ao estoque.

“…In particular, the pollution by heavy metals has been increasing with the development of industry, and it has already been proved that a high concentration of heavy metals has a dangerous impact on living organisms and the environment as hazardous materials [8][9][10]. It can be accumulated in living organisms and inhibit their metabolism to the point of death [11,12]. Accordingly, water treatment has been essentially required, in that water quality should be improved for water resource recirculation in conditions of limited water resources.…”

This study was conducted using alginate-rhamnolipid (Alg-Rh) solutions on copper ions (Cu2+) as an application of coagulation with aluminum sulfate (Al2(SO4)3). The results show that solid phases were rapidly formed as an output of the reaction between Alg-Rh and Al2(SO4)3. It could be considered that the Al2(SO4)3 concentration and the existence of Cu2+ have an impact on forming hard coagulation, in that the total volume has been increased with increasing Al2(SO4)3 and the existence of Cu2+. The number of ions of aluminum (Al3+) and sulfate (SO42−) were also increased with Al2(SO4)3. The efficiency of Cu2+ removal was constant above 75.0%, hence the average value was 76.8%.

The presence of cadmium (Cd) in Latin American produced food has been in the spotlight in recent years. Regarding food safety, this element can be toxic to humans at low exposure levels, and its monitoring is a question of public health. Cadmium concentrations from different sources, such as water, soil, sediments, food and beverages were examined and discussed to address the non-occupational exposure of the Latin American population. A literature review was conducted, which considered publications from 2015 to 2020 and available in the ScienceDirect and PubMed databases. Twenty-eight papers were considered for Cd in water, forty-nine for Cd in soil and sediments, and eighty-six for Cd in food. We identify and discuss factors affecting Cd environmental behavior and bioaccumulation, the main species used in monitoring studies, and the necessity for future research. Brazil and Mexico are the countries with the most available information, whereas for some countries in Central America, no information was found. The Cd levels in food examined in these studies (mostly fish and cacao) were generally below the established maximum levels, indicating a low risk. When considering the presence of Cd in food, water, and soil, Cd fractionation and chemical speciation studies are fundamental to understand which Cd species are the most toxic. In turn, studies on bioaccessibility and bioavailability of Cd in food are also needed for more adequate risk assessment but they are currently scarce in all of Latin America.
