“…In this report, the concentration of Zn and the higher concentrations of Cu confirm the relevance of these elements in the metabolism of estuarine crabs (Anandkumar et al, 2019) like C. bellicosus. In addition, the high concentration of Zn and Cu (and the other trace metals) could also be attributed to the high phosphorus, urea, and TSS concentrations that have been reported in the area from April to November drained by agriculture and shrimp aquaculture (Martínez-López et al, 2017;Góngora-Gómez et al, 2018).…”

This study was carried out in the Navachiste coastal lagoon, Mexico, surrounded by intensive agricultural and aquaculture activities that cause environmental pollution by the deposition of trace metal residues in the sediments of this coastal lagoon. The trace metals are bioaccumulated by benthic organisms such as the blue swimming warrior crab, Callinectes bellicosus, which inhabits this lagoon and is consumed by humans. Ninety-five C. bellicosus edible tissue samples were collected (April 2014–January 2015). The extraction procedure of the trace metals in edible tissue samples was carried out by acid digestion with nitric acid. Based on the Environmental Protection Agency (EPA) of the United States, two indices were used to measure health risk: the estimated daily intake (EDI) and the target hazard quotient (THQ). The hazard index (HI) was used to calculate the probability of adverse carcinogenic risk and the target hazard quotient per sample (MHI) to calculate the probability of developing a carcinogenic or non-carcinogenic risk. The analysis of variance (ANOVA) showed significant differences among trace metal concentrations (p < 0.01), but all trace metal concentrations in the edible tissues of C. bellicosus were higher than the maximum residual limits (MRLs). The highest EDI was for Zn, Fe, and Cu, showing that the consumption of these crabs might represent health risks. The THQ >1 was for Ni, Zn, Cd, and Cu, and the HI = 16 revealed the risk of C. bellicosus for high-level consumers. The MHI showed that 98% of samples presented a THQ >1, implying a high rate of bioaccumulation of trace metals by the crabs independent of the sampling site in the NAV. The presence of trace metals in the edible tissue of crabs reflects contamination by trace metals, and the indices results mean that the NAV lagoon is constantly polluted with trace metal residues by neighboring agriculture and aquaculture activities. These trace metal residues are being bioaccumulated in the edible tissues of C. bellicosus due to its feeding habits, resulting in a health risk if its consumption is high, including carcinogenic and non-carcinogenic risks.

“…Classifying the "El Conchalito" estuary as a mesotrophic zone using Carlson's Index provides further evidence of the system's excellent health, for there is no scientific evidence of eutrophication due to anthropogenic activities, as has occurred in other coastal lagoons in Mexico (Gómez-Ortega et al, 2017;Martínez-López et al, 2017). It is important to mention that diverse lines of research involving various biotic resources, including birds (Carmona & Carmona, 2000), fish (González-Acosta et al, 1999;González-Acosta et al, 2005), and mollusks (Conabio, 2008), and crustaceans (Félix-Pico et al, 2003), allow us to infer that this is a zone with mid-to-high productive capacity that plays a significant role in maintaining regional -even continental-biodiversity, since it receives some migrant species, especially of birds.…”

RESUMEN. Los sistemas de manglar, tradicionalmente han sido reportados como áreas de alta productividad primaria, capaces de exportar biomasa hacia sistemas adyacentes favoreciendo a organismos de diferentes niveles tróficos. Su complejidad como sistemas altamente productivos estriba en gran parte en la coexistencia de productores primarios tanto foto como quimiosintéticos. El objetivo del presente estudio es determinar el estado trófico, la eficiencia fotosintética y productividad primaria de la comunidad fitoplanctónica presente en este manglar durante la temporada primavera verano del 2016. Se realizaron muestreos quincenales durante el periodo abril a julio en los cuales se tomaron muestras para determinación de concentración de clorofila a y estimación de la productividad primaria. De igual manera se registró la temperatura ambiental y la superficial del agua, además de considerar datos de niveles de mareas. La temperatura ambiente varió entre los 21.9 y 28.5 ° C, mientras que la temperatura superficial del agua presentó valores entre 21 y 24.5 °C. Los menores niveles de marea se registraron durante el primer y segundo muestreo (50 cm), mientras que los máximos durante la tercera y cuarta fecha (120 cm). Con relación a la concentración de clorofila a, su valor mínimo fue de 2.0 mg m-3, mientras que el máximo de 4.6 mg m-3 (julio y marzo respectivamente). Durante Julio se registró el mínimo de productividad primaria (2.4 mg C m-3 h-1), mientras que el máximo durante abril con 4.9 mg C m-3 h-1. La eficiencia del proceso fotosintético presentó el mínimo durante mayo (0.79 y el máximo durante julio (1.20 mg C m-3 h-1), coincidiendo con el mínimo de productividad primaria. De acuerdo al Índice Trófico de Carlson (> 30), el Estero El Conchalito se considera una zona de productividad media.

“…Ammonium is an indicator of contamination with fresh organic matter [70]. Its entry into the lake stimulates an increase in the amount of phytoplankton [71], which, in turn, creates favorable trophic conditions for M. leuckarti. The source of pollution of the lake by easily oxidizable organic matter (Figure 2e) is, obviously, surface runoff from the beach area of the east coast (anthropogenic source) and river runoff from the west coast (natural source).…”

The enrichment of the protected Borovoe Lake with nutrients has taken place within the last 100 years, from the moment the first resort was formed on its shores. The purpose of this study was to assess the current ecological state of Borovoe based on the structure of zooplankton. According to the chemical data, in the summer of 2019, the content of nutrients in the water was, relatively, not high; the content of heavy metals was very low. Twenty-seven species were found in zooplankton. The average abundance of zooplankton was 988.8 thousand ind./m3 with a biomass of 1.52 g/m3. Rotifera dominated. Cladocera sub-dominated. The Shannon index values were 2.31 bit/ind. and 2.57 bit/mg; the values of Clarke’s W-statistics and Δ-Shannon were negative. The abundance of zooplankton increased more than nine times, but the average individual mass of an organism decreased from 0.0112 to 0.0016 mg over the past decade. Despite the relatively low content of nutrients, the structure of zooplankton demonstrated that the nutritional load on Lake Borovoe is currently close to critical. Statistical mapping of the data and redundancy analysis (RDA) showed that the primary source of lake pollution is the village of Borovoe and sanatoriums located on the southeast and northwest coasts.
