    MOREIRA, LUCAS B.; VICENTE, THAISA M.; TANIGUCHI, SATIE; HORTELLANI, MARCOS A. ; SARKIS, JORGE E.S. ; BICEGO, MARCIA C.; ABESSA, DENIS M. de S.. Assessing legacy contaminants in sediments from marine protected areas of the central coast of São Paulo (Brazil). Brazilian Journal of Oceanography, v. 65, n. 4, p. 549-563, 2017. DOI: 10.1590/S1679-87592017128806504

    Abstract: The presence of legacy contaminants in sediments from three Marine Protected Areas (MPAs) of the coast of São Paulo State was evaluated. Four sampling surveys were conducted between 2013 and 2015 in 10 sites, distributed along the Laje de Santos Marine and Xixova-Japui State Parks (PEMLS and XJSP, respectively) and Central Coast Marine Protection Area (APAMLC). Samples were analyzed for sediment texture, total organic carbon, CaCO3, metals (Al, Fe, Hg, Cd, Co, Cr, Cu, Ni, Pb and Zn), aliphatic and polycyclic aromatic hydrocarbons (AH and PAH). Sediments were generally sandy (excepting muddy samples from APAMLC), with variable amounts of TOC, OM and CaCO3. Most of the sediments exhibited low to moderate concentrations of metals, except APAMLC. Low contamination of sediments by hydrocarbons was found but samples from XLSP and APAMLC exhibited the highest concentrations of biogenic AH and PAH from pyrogenic sources. In APAMLC and PEMLS, the levels of metals can be considered as background levels according to geochemical indices (Igeo and EF). In XJSP and especially in APAMLC data indicated poor sediment quality, probably due to the effect of anthropic activities.

Can the colors of beach-stranded plastic pellets in beaches provide additional information for the environmental monitoring?: A case study around the Port of Santos, Brazil. International Aquatic Research, v. 14, n. 1, p. 23-40, 2022. DOI: 10.22034/IAR.2022.1943050.1205

    Abstract: Plastic pellets are granules of different polymers used in the manufacture of various plastic products. Plastic pellets can reach the environment due to losses after their manufacturing process, especially the transportation. Loading in harbour areas and transport by ships are the main sources of plastic pellets to the ocean and coastal areas. After pellets reach the environment, they may adsorb and concentrate chemicals contaminants from different sources. Moreover, the weathering of plastic pellets may result in color changes, from white to brownish. This study aimed to analyse the color pattern of pellets collected on beaches of the central coast of São Paulo, Brazil, as an indicator of weathering and ageing processes. Plastic pellets were collected in four sampling surveys conducted between April 2012 and September 2015, and then separated in five color groups: white, yellowish, orange, brown, and pigmented. All sampled beaches had a consistent pattern of light-toned pellets (white and yellowish). This pattern was also found over time, suggesting a constant supply of plastic pellets to the beaches, coming from the harbour area. We also recommend the use of the color pattern of plastic pellets in citizen science monitoring programs.

    Abstract: This short note aims to report in detail a preliminary assessment of the concentrations of Cd, Hg and Pb in tissues of blue crabs Callinectes danae collected from the Cananéia-Iguape-Peruíbe estuarine complex (CIP), in the South of São Paulo State coast, Brazil. In October 2014, blue crabs were collected from CIP. Tissues were removed by dissection and metal determination was performed by GF-AAS and CV-AAS. According to statistical analysis, Pb and Cd concentrations in gills were significantly higher than those found in muscles and hepatopancreas, respectively. There were no significant differences in Hg concentrations between samples. Cd, Hg and Pb concentrations in gills and hepatopancreas were lower than those reported in a previous study performed at CIP. However, Cd concentration in hepatopancreas was higher than the Brazilian limit for consumption and new efforts to monitor Cd concentrations in C. danae tissues must be performed.

    Abstract: This study aimed to assess the bioaccumulation of Pb and induction of metallothionein-like proteins (MT) in Callinectes danae through single and combined dietary and waterborne exposures. Male C. danae individuals were collected in the south area of the Cananéia-Iguape-Peruíbe Protected Area (APA-CIP), in São Paulo State, Brazil. After an acclimatization period, exposure assays were performed during 7 and 14 days, at two Pb concentrations (0.5 e 2.0 µg/g) in 4 treatments: 1) control; 2) contaminated water only; 3) contaminated food only; 4) contaminated water and food. The results indicate that C. danae is highly tolerant to Pb exposure at the evaluated concentrations. In gills, Pb bioaccumulation is more dependent of water efflux and time of exposure (higher Pb values). However, pathways act simultaneously in the induction of MT expression in this tissue. The decreases in Pb accumulation in the combined treatments and MT increases after 14 days in gills suggests that these proteins play a detoxification function in the presence of Pb. In hepatopancreas, depending on the predominance of a certain pathway or combined pathways, accumulation occured at different times. For muscle tissue, bioaccumulation was observed due to contaminated water exposure, but not dietary exposure, probably because Pb concentrations were low.

International Journal of Environmental Research, v. 13, n. 2, p. 431-434, 2019. DOI: 10.1007/s41742-019-00170-3

    Abstract: This technical note aims to report, in detail, the development, suitability and analytical validation of an artificial food to assess metal bioaccumulation in the blue crab Callinectes danae after metal exposure assays. For this purpose, lead (Pb) was chosen as the metal of interest. First, a non-contaminated artificial food was prepared by mixing commercial shrimps and agarose. The food was then offered on alternate days to two groups of crabs for 7 and 14 days, respectively. After confirming that this food was well-accepted by crabs, analytical procedures were performed to confirm that Pb added to the mixture would remain in the artificial food. For this purpose, two foods containing Pb at concentrations of 0.5 and 2.0 μg g− 1 were prepared by adding aliquots of an ultrapure Pb standard solution to the mixture. Samples of each food were subjected to an acid extraction and Pb concentrations were determined by a GF-AAS. Pb recoveries in both contaminated foods were > 90%. Subsequently, another experiment was performed, and two groups of crabs were fed with contaminated artificial foods (0.5 and 2.0 μg g− 1 of Pb) during 7 and 14 days, respectively. The observed acceptance of these foods by crabs at both Pb concentrations was of 100%.

Lead toxicity on a sentinel species subpopulation inhabiting mangroves with different status conservation. Chemosphere, v. 251, p. 1-13, 2020. DOI: 10.1016/j.chemosphere.2020.126394

    Abstract: Lead is a priority pollutant introduced in the aquatic environment by different sources commonly located in estuarine regions, such as ports, marinas and industries. Environmental agencies around the world set the maximum allowable concentration of lead in effluents, surface water and sediment, but few studies reported its accumulation and chronic toxicity in mangrove benthic invertebrates using concentrations believed to be safe. In the case of Brazilian mangrove environments, Ucides cordatus is a crab species of choice to be used in bioaccumulation studies. We have assessed biomarkers’ responses (DNA strand breaks, micronucleated cells, metallothioneins, enzymatic activity of aminolevulinic acid dehydratase and neutral red retention time) and the total bioaccumulation in six tissues of U. cordatus crabs resident to mangrove areas under different conservation status during a 28-day period bioassay. We also investigated Pb subcellular partition and biomarkers’ responses using a supposedly safe concentration (10 mg L 1). During the Pb exposure, the highest concentration of Pb was observed in crab gills. Crabs also showed a high ability to allocate Pb in detoxified forms. Multivariate analysis pointed out that bioaccumulation (total, active and detoxified) is linked to biomarkers. Even in supposedly safe dosage, U. cordatus triggered its defense mechanisms expressing more metallothioneins and presented relevant cyto-genotoxic damage. Our data suggest the development of biological tolerance to Pb in crabs from polluted areas. Our results provided a new insight about lead toxicity even at concentrations considered environmentally safe, which could support new strategies to manage estuarine areas considering their respective conservation status.

Simple and cost-effective method for microplastic quantification in estuarine sediment: a case study of the Santos and São Vicente Estuarine System. Case Studies in Chemical and Environmental Engineering, v. 2, p. 1-5, 2020. DOI: 10.1016/j.cscee.2020.100020

    Abstract: Sediment is a useful environmental compartment in the evaluation and monitoring of microplastics (i.e., plastic particles between 1 μm and 5 mm in length) in aquatic environments, since 70% of plastic waste is deposited on the ocean floor, in riverbeds, and on the bottom of estuaries. The techniques typically used to separate and quantify microplastics require extensive sample preparation and are often ineffective for estuarine sediment samples. In this study, we present a new method for separating and quantifying microplastics found in estuarine sediment samples. This procedure involves sediment collection, drying, sieving (2.0, 1.0, 0.5 and 0.25 mm mesh sizes), and stereomicroscopic examination of the samples retained in each sieve. The results were measured as microplastic abundance (particles g-1 of sediment). This method allows researchers to estimate total microplastic abundance and distribution at the sieve meshes tested, calculate thread/fiber and fragment proportions, and separate microplastic samples for subsequent Py-GC/MS analysis in order to identify their respective compositions. This method was found to be effective in precluding the need for solvents and reducing the amount of time required for sample preparation. For these reasons, this method is more cost-effective and generates less environmental impact than those currently available.

A tiered approach to assess effects of diclofenac on the brown mussel Perna perna: a contribution to characterize the hazard. Water Research, v. 132, p. 361-370, 2018. DOI: 10.1016/j.watres.2017.12.077

    Abstract: Pharmaceutical discharges into the aquatic ecosystem are of environmental concern and sewage treatment plants (STPs) have been pointed out as the major source of these compounds to coastal zones, where oceanic disposal of sewage occurs through submarine outfalls. Diclofenac (DCF) is one of the most frequently detected pharmaceuticals in water, but little is known about the effects on marine organisms. In this study, we employed a tiered approach involving the determination of environmental concentrations of DCF in marine water and the adverse biological effects for fertilization, embryo-larval development and biomarker responses of the mussel Perna perna. Results indicate that effects in fertilization rate and embryo-larval development were found in the order of mg$L 1. However, low concentrations of DCF (ng$L 1) significantly decreased the lysosomal membrane stability and COX activity, as well as triggered DNA damage, oxidative stress and changes in antioxidant defenses. Our results point to an environmental hazard at coastal ecosystems and suggest the need for improvements in the treatment of domestic wastewater aiming to reduce DCF concentrations, as well as regulation on current environmental legislation and monitoring of aquatic ecosystems.

Toxicity of glitter to marine organisms: a baseline study with embryos of the sand-dollar Mellita quinquiesperforata. International Aquatic Research, v. 15, n. 2, p. 181-189, 2023. DOI: 10.22034/IAR.2023.1973104.1359

    Abstract: This study aimed to determine the toxicity of glitter particles of two colors (green and white) on the embryos of the sand dollar Mellita quinquiesperforata. Toxicity tests were performed using both green- and white-glitter particles. Adult sand dollar individuals were collected and gametes were obtained by osmotic induction. Each glitter was tested in five test solutions: 0.01, 0.1, 1, 10 and 100% (= mg L-1). The results were analyzed by the Wilcoxon–Mann–Whitney test, allowing the determination of the lowest observed effect concentration (LOEC) and the no observed effect concentration (NOEC). The LOECs calculated for the green glitter dispersions were 0.01 % (P < 0.05) in the first two tests, and 100% in the third test. The LOECs for the white-glitter dispersions ranged from 0.01 % to 0.1 %. Our results demonstrate that glitters of both colors are capable of affecting the embryonic development of M. quinquiesperforata.
