“…Recurring exposure to low levels of Pb creates serious health issues for infants and children such as slow development and permanent intellectual disability [ 10 , 11 ]. In addition to various sources, lead can be taken up by fishes and other aquatic organisms from water accumulating in humans tissues after consumption [ 12 ], and then resulting in neurological [ 13 ], hematopoietic [ 14 ], musculoskeletal [ 15 ], cardiac function [ 16 ] and reproductive damages [ 17 , 18 ]. Despite the detrimental properties of lead to living objects, there is yet a significant gap to efficiently and abruptly detect and characterize lead at extremely small levels in bioactive compounds [ 19 , 20 ].…”

Lead detection for biological environments, aqueous resources, and medicinal compounds, rely mainly on either utilizing bulky lab equipment such as ICP-OES or ready-made sensors, which are based on colorimetry with some limitations including selectivity and low interference. Remote, rapid and efficient detection of heavy metals in aqueous solutions at ppm and sub-ppm levels have faced significant challenges that requires novel compounds with such ability. Here, a UiO-66(Zr) metal-organic framework (MOF) functionalized with SO3H group (SO3H-UiO-66(Zr)) is deposited on the end-face of an optical fiber to detect lead cations (Pb2+) in water at 25.2, 43.5 and 64.0 ppm levels. The SO3H-UiO-66(Zr) system provides a Fabry–Perot sensor by which the lead ions are detected rapidly (milliseconds) at 25.2 ppm aqueous solution reflecting in the wavelength shifts in interference spectrum. The proposed removal mechanism is based on the adsorption of [Pb(OH2)6]2+ in water on SO3H-UiO-66(Zr) due to a strong affinity between functionalized MOF and lead. This is the first work that advances a multi-purpose optical fiber-coated functional MOF as an on-site remote chemical sensor for rapid detection of lead cations at extremely low concentrations in an aqueous system.

“…Nevertheless, Pb-induced alterations during development are largely overlooked, and most of the available studies have been conducted on adults. Pb was reported to induce several detrimental effects in adult fish, including neurotoxicity [8,24,25], alteration of liver metabolism [26,27], oxidative stress induction [28][29][30], immunological and haematological dysfunctions [22,[31][32][33][34] and alteration of gills and liver histology [32,[35][36][37][38].…”

Morphological and Molecular Alterations Induced by Lead in Embryos and Larvae of Danio rerio

Lead (Pb) is one of the most toxic and persistent elements and may adversely affect both humans and wildlife. Given the risks posed to humans, lead is listed among priority substances of public health importance worldwide. In fish, available studies deal with high doses, and the potential hazard of Pb at low concentrations is largely unknown. Given its well-demonstrated translational value for human toxicity research, we used zebrafish as a model species. Embryos were exposed to two environmentally relevant concentrations of lead (2.5 and 5 µg/L) from 6 h post-fertilization and analyzed after 48, 96, and 144 h. The morphological abnormality arose after 48 h, and the incidence and intensity were dose and time dependent. Spinal and tail deformities were the most frequently detected alterations. Pb also modulated the expression of genes involved in the toxicological responses (sod and mt), thus demonstrating that zebrafish’s early stages are able to mount an adaptive response. Moreover, ldh and β-catenin were significantly upregulated in all groups, whereas wnt3 expression was increased in the high concentration group. Our results confirm that zebrafish embryos and larvae are valuable early warning indicators of pollution and may play a major role in ecosystems and human health monitoring.

“…O nitrato entra em organismos aquáticos através da difusão passiva nas células branquiais, e a principal ação tóxica é devido a conversão endógena de nitrato em nitrito, que então causa a formação de metahemoglobina, resultando na perda da capacidade de transporte de oxigênio no sangue (Gomez Isaza et al, 2021) e consequentemente a morte dos indivíduos. Além disso, o nitrato é capaz de interromper a síntese de esteroides, comprometendo a reprodução (Kellock et al, 2018), e causar histopatologias em brânquias de peixes, como necrose, hiperplasia, fusão lamelar, edemas e degeneração da lamela (Paul et al, 2019;Dutra et al, 2019).…”

Os compostos nitrogenados (nitrito, nitrato e amônia) são considerados tóxicos para os peixes, pois são capazes de promover alterações histológicas e bioquímicas, diminuir a capacidade de trasnporte de oxigênio no sangue e afetar o fitness (i.e. aptidão do organismo em termos de crescimento e natação). Esses compostos acumulam no ambiente aquático através da excreção de organismos aquáticos, da decomposição de matéria orgânica tanto de origem aquática quanto do sistema terrestre adjacente, e da entrada direta pelo sistema terrestre, afluentes e águas subterrâneas. As chamadas mudanças globais, como as climáticas e de uso do solo, podem potencializar e intensificar essa entrada dos compostos nitrogenados através de atividades humanas, tais como a agricultura e o lançamento de efluentes, como esgoto doméstico. Os peixes estão comumente em contato com diversos poluentes, e a combinação de fatores ambientais como temperatura, pH, disponibilidade de oxigênio e dureza podem ter efeitos sinérgicos ou antagônicos. No entanto, como esses fatores ambientais afetam a toxicidade da amônia, nitrito e nitrato não são totalmente compreendidos. Portanto, nosso objetivo foi revisar a literatura afim de abordar os efeitos dos compostos nitrogenados, e como os parâmetros físico-químicos da água afetam a toxicidade desses compostos.
