The use of pesticides in Mexican agriculture creates an interest learning about the presence these substances different environmental matrices. Glyphosate (GLY) is herbicide widely used state Campeche, located Mayan zone western Yucatan peninsula. Despite fact that GLY considered a non-toxic pesticide to humans, its water bodies through spillage, runoff, and leaching are risk human health or biota inhabit ecosystems. In present study, glyphosate residues were determined groundwater, bottled...
Under natural conditions, organisms are exposed to multiple stressors simultaneously, such as microplastic (MP) contamination and rising global temperatures. To assess the combined effects of acute MP exposure increasing temperatures on fiddler crab Minuca rapax, we crabs polyethylene microspheres (0 2 mg L-1, size 53-63 μm) at three different (24, 27, 30 °C). Physiological responses were assessed by measuring oxygen consumption evaluating biochemical activities superoxide dismutase (SOD),...
Ecotoxicological tools, namely biomarkers and bioassays, may provide insights on the ecological quality status of mangroves under restoration. We investigated how 1) physicochemical parameters water bioassays using Artemia franciscana; 2) quantification sublethal (osmoregulatory capacity, biochemical, oxidative stress) individual (density, length-weight relationship [LWR], parasitic prevalence) in sentinel fiddler crab Minuca rapax, can improve restoration indicators from Yucatán Peninsula,...
Strandings provide valuable information about rare marine organisms and their relationship with environment. In the southern Gulf of México, specifically on central coast Campeche, Mexico, strandings oceanic cetaceans have rarely been recorded, therefore, biological has also scarce. One such stranding cases occurred September 7, 2022, Seybaplaya, Campeche. The specimen was identified as a female Tursiops truncatus morphology features ecotype. carcass examined shortly after death, samples for...
Disinfection by-products to obtain drinking water, such as CH2Cl2, CHCl3, and BrCHCl2, elicit cytotoxicity hyperproliferation in human lung fibroblasts (MRC-5). Enzymes of their biotransformation modulate these damages can generate toxic metabolites. However, it is unknown that the response oxidative stress involved cellular modulated by nuclear factor-kappa B (NF-κB). Hence, MRC-5 cells were treated with compounds evaluate ROS, lipid peroxidation, phospho-NF-κB/p65...
Abstract This work evaluated the biochemical responses of endogeic earthworm Balanteodrilus extremus exposed for 14 and 48 days (d) to soils collected from two tropical agricultural systems: maize-sorghum (MS) soybean-sorghum (SS). A soil without management (WAM) use pesticides was selected as a reference. The presence organochlorine (OC) organophosphate (OP) pesticide residues quantified in MS SS soils. Biomarkers detoxification [glutathione S transferase (GST)], neurotoxicity...

However, it is unknown that the response oxidative stress involved cellular modulated by nuclear factor-kappa B (NF-κB). Hence, MRC-5 cells were treated with compounds evaluate ROS, lipid peroxidation, phospho-NF-κB/p65 (Ser536) levels, CAT,...
The aim of this study was to analyze the effect acute exposition polycyclic aromatic hydrocarbons (PAHs) in four different concentrations (4.37, 8.73, 17.46, 34.95 µg L−1) Gambusia yucatana, an endemic fish Yucatán Peninsula by characterization biomarkers activities: EROD, GST, TBARS, SOD, CAT, and GPx on liver; AChE brain. EROD GST activities increased 292% 754%, respectively, at highest concentration (p < 0.0001). TBARS decreased 51%, 49%, 36% three last SOD activity 56% 0.05). There no...
To describe the seasonal response of major phytoplankton groups to environmental variables along Campeche coast, southeastern Gulf Mexico, seven shallow-water (ca. 1 m) stations were monitored from January 2019 2020. Orthophosphate, ammonium, nitrite, nitrate and silicate measured. Several tests, including ANOVA, Kolmogorov–Smirnov test, Tukey TSD, Bartlett’s test canonical correspondence analysis (CCA), applied. The physicochemical (temperature, salinity pH) recorded are typical for central...
Goodea gracilis is an endemic fish that only habitats in some water bodies of Central Mexico are contaminated with cyanobacteria-producing microcystins (MC); however, a lack information on this topic prevails. With the aim to generate first approximation about physiological changes elicited by cyanobacterium produce MC congeners species, specimens born laboratory was exposed for 96 h cell densities 572.5, 1145, 2290, 4580, and 9160 × 106 cells Microcystis aeruginosa strain LB85/L, set novel...
