“…Furthermore, the safest fish to eat is a function of the metal under subject as well as the geographical area where the species was caught; for example, muscle tissue from black rainbow trout has been reported to have Cd (1.52 mg/kg, non-regulated) in Apurímac [ 119 ], but none was found in the same species caught in Cajamarca [ 77 ]. Similarly, the native fish jumilla ( Parodon buckleyi ) has shown low regulated metal contents ( Table S5 ), suggesting that this species could be safer to consume; however, Rosales et al [ 120 ] reported Cd concentrations higher than 1.6 mg/kg in the same species in Huánco. Brown trout ( Salmo trutta ) seems to have low metal content ( Table S5 ), inconsistent with other studies that have found high metal concentrations in the same species in Norway (e.g., [ 121 ]).…”

“…[ 127 ] (as previously mentioned), which are much higher than what other authors have found in the Mediterranean Sea [ 129 ] and Brazilian markets [ 130 ], respectively, for the same species. Moreover, the metals that were reported at the highest concentrations nationwide were Ba (15.57 mg/kg) in rainbow trout [ 77 ], Cd in royal pleco ( Panaque nigrolineatus ) (1.62 mg/kg) [ 115 ] and jumilla ( Parodon buckleyi ) [ 120 ], and Pb in rainbow trout (10.45 mg/kg) [ 77 ]. It is important to keep in mind that only CH 3 -Hg, Sn (canned fish), and Pb (fish and four fish species) are regulated under the international WHO standards (see Table S1 and Section 2.1 ), indicating an urgent need to regulate other metals that have been found in high concentrations in Peru, to ensure that people in the country are not at risk of ingesting unhealthy amounts of these contaminants.…”

To better query regional sources of metal(loid) exposure in an under-communicated region, available scientific literature from 50 national universities (undergraduate and graduate theses and dissertations), peer-reviewed journals, and reports published in Spanish and English were synthesized with a focus on metal(loid) bioaccumulation in Peruvian food and medicinal products utilized locally. The study considered 16 metal(loid)s that are known to exert toxic impacts on humans (Hg, Al, Sb, As, Ba, Be, Cd, Cr, Sn, Ni, Ag, Pb, Se, Tl, Ti, and U). A total of 1907 individual analyses contained within 231 scientific publications largely conducted by Peruvian universities were analyzed. These analyses encompassed 239 reported species classified into five main food/medicinal groups—plants, fish, macroinvertebrates and mollusks, mammals, and “others” category. Our benchmark for comparison was the World Health Organization (Codex Alimentarius) standards. The organisms most frequently investigated included plants such as asparagus, corn, cacao, and rice; fish varieties like trout, tuna, and catfish; macroinvertebrates and mollusks including crab and shrimp; mammals such as alpaca, cow, chicken eggs, and milk; and other categories represented by propolis, honey, lichen, and edible frog. Bioaccumulation-related research increased from 2 to more than 25 publications per year between 2006 and 2022. The results indicate that Peruvian food and natural medicinal products can have dangerous levels of metal(loid)s, which can cause health problems for consumers. Many common and uncommon food/medicinal products and harmful metals identified in this analysis are not regulated on the WHO’s advisory lists, suggesting the urgent need for stronger regulations to ensure public safety. In general, Cd and Pb are the metals that violated WHO standards the most, although commonly non-WHO regulated metals such as Hg, Al, As, Cr, and Ni are also a concern. Metal concentrations found in Peru are on many occasions much higher than what has been reported elsewhere. We conclude that determining the safety of food/medicinal products is challenging due to varying metal concentrations that are influenced not only by metal type but also geographical location. Given the scarcity of research findings in many regions of Peru, urgent attention is required to address this critical knowledge gap and implement effective regulatory measures to protect public health.

“…Los conocimientos acumulados sobre metales pesados indican que los componentes bióticos y abióticos de los ecosistemas de agua dulce superficial son los más afectados (Rosales et al, 2019; Aportela y Paulino, 2020); sin embargo, no siempre es posible estimar el impacto real de la interacción biotametales pesados. Influyen en este hecho la existencia de una gran variedad de elementos metálicos, la formación de mezclas difíciles de prever y cuantificar, y los complejos mecanismos de acción, así como la enorme variedad de organismos acuáticos involucrados, entre otros factores (Wu et En este contexto tan complejo, la histopatología puede convertirse en una valiosa herramienta en estudios ambientales de fuentes antropogénicas generadoras de es-pecies metálicas (Van der Oost et al, 2003).…”

Se notifica la respuesta tisular del pez Gambusia punctata (Poey, 1854) crecido en condiciones naturales bajo la exposición crónica de metales pesados. Se capturaron individuos adultos de ambos sexos, a 10 km aguas debajo de una antigua zona minera a cielo abierto en Santiago de Cuba, Cuba. Se identificaron deformaciones branquiales con una extensión moderada en el 80% de los individuos investigados. Asimismo, el 100% presentó numerosos depósitos de hierro férrico en el interior de los enterocitos.

Eco-effective Sustainable Risk Assessment Model for homogeneous solid waste mortars based on the Cradle to Cradle paradigm

et al. 2023

IntroductionThe unrestricted use of non-renewable natural resources in masonry mortars and the rapid increase in solid waste contribute to the deterioration of the environment. It is a priority for the United Nations to promote growth without compromising the ability of new generations to attend to their own; for this purpose, 17 Sustainable Development Goals for all countries have been formulated. The present work arises from the need to propose a model to evaluate, in the design phase, homogeneous solid waste and total or partial substitutes for some of the components of the mortars used in the construction sector, based on the Cradle to Cradle paradigm, which has the objective of including improved materials for the health of living beings and the environment by establishing a circular system in the manufacture of mortars including only safe and healthy materials that can be reused with a guarantee of not affecting the health of living beings and the environment and contributing to sustainability.MethodsBased on the positivist epistemological current, projective documentary research begins by analyzing scientific publications that recommend the use of solid waste only to verify its rheological properties, ignoring how the inclusion of this material can affect living beings and the environment; it is contrasted with the results of published public access research regarding the chemical substances that make up said material.ResultsThe eco-effective model is designed and its application is validated in identifying potential risks to the health of living beings and the environment in the waste of the selected cases; recommending the avoidance of recycling those materials that cause concern; contributing improved mortar designs for living beings and the planet, which minimize the use of natural resources and increase productivity in the field of construction; and implementing this vision through continuous development and improvement.ConclusionsThe eco-effective model facilitates doing the right things from the design stage, promoting growth with opportunities, diversity, and abundance for the present generation as well as future generations.
