DuBois S, Lacy B, Rahman AF, Rahman MS. Elevated CYP1A expression detected in pinfish collected from a coastal lagoon in the southern Texas Gulf Coast: indicative of exposure to microplastics or pollutants? ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2021; 28:32066-32073. [PMID: 33982254 DOI: 10.1007/s11356-021-14351-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 05/06/2021] [Indexed: 06/12/2023]
Abstract
The marine environment is increasingly polluted by anthropogenic wastes, notably plastic debris. This debris breaks down into smaller pieces, known as microplastics. When consumed by marine organisms, microplastics cause various physiological effects. In this study, we sought to determine a link between ingested microplastics and cytochrome P450-1A (CYP1A) expression in fish liver. To achieve this goal, we collected pinfish from five sites in Lower Laguna Madre (LLM, a large coastal lagoon), analyzed stomach contents, excised liver tissues, and performed immunohistochemical analysis to determine CYP1A expression. Microplastics were not discovered in the stomach/intestine of pinfish, though plastic debris was present at various stages of decomposition within sampling sites. Hepatic CYP1A expression was significantly higher in pinfish collected from four of five sampling sites when compared to fish in laboratory conditions. These results imply that pinfish, as well as other organisms, may be exposed to pollutants other than microplastics in LLM.

Abstract
Our study evaluated heavy metal concentrations in soft tissues of sea hare, Aplysia fasciata, from the Lower Laguna Madre, Texas. Heavy metals in tissues followed Se>As>Pb>Cd. Concentrations ranged As (BDL-28.08), Cd (BDL-5.50), Pb (BDL-12.85) and Se (4.25-93.43ppm). Median As, Cd, Pb, and Se tissue levels exceeded exposure levels. Significant relationships occurred in metal-metal (AsCd, AsPb, CdPb, CdSe, and PbSe), metal-tissue (significant Se uptake by inhalant and exhalant siphons and As in the hepatopancreas), and metal-metal within tissue (AsPb in the hepatopancreas and CdPb in the digestive cecum) analyses (p<0.05). Bioaccumulation factors (BAF) suggested the inhalant siphon, hepatopancreas, and digestive cecum function as macroconcentrators of Cd, hepatopancreas and digestive cecum as macroconcentrators of Pb, and all tissues were deconcentrators for As and Se. As a bioaccumulator of heavy metals, Aplysia was evaluated as a bioindicator of marine pollution in harbors and bays.

Abstract
Trace elements concentrations (As, Ba, Cd, Cr, Cu, Ni, Pb, V and Zn) were found in samples of Halodule wrightii Aschers (Cymodoceaceae) seagrass from Todos os Santos Bay, Bahia, Brazil by inductively coupled plasma mass spectrometry (ICP-MS). This bay has been impacted by the presence of industrial activity that includes chemical and petrochemical plants as well as an oil refinery and harbor activities located in the north and northeastern area. Samples were collected at 4 stations to evaluate the distribution of element concentrations in this area and under different climatic conditions. The mean concentrations, in mgkg(-1), found in dry tissues for all the studied metals and stations were: As (1.08-5.42), Ba (3.72-32.0), Cd (0.135-1.68), Cr (1.15-10.4), Cu (2.23-13.4), Ni (1.95-9.87), Pb (0.873-5.18), V (3.39-22.4) and Zn (13.1-39.5). Statistical analysis (ANOVA) of the seagrass data showed significant inter-site differences for all elements examined except nickel and vanadium.

Abstract
An assessment of contaminant stressors on biota of the Rio Grande was conducted to identify relevant contaminant issues, assess exposure and ecological effects, identify data gaps, and determine potential risks. Most contaminant data were from studies conducted during 1965-1995 in the Lower Rio Grande, on the Texas side of the river, within a 100-km boundary from Falcon Dam to the mouth. Contaminants most frequently reported were organochlorine compounds (OCs) and trace elements. The number of records for OCs and trace elements was at least twofold greater for fish than for birds, mammals, or reptiles. Of the OCs, p,p'-DDE was the most commonly reported. Among the trace elements, Hg was one of the most frequently reported; however, Se, As, Pb, Cu, and Zn were also common. The highest concentrations of OCs and trace elements were reported predominantly from Lower Rio Grande Valley locations, with approximately 68% of the highest values detected from Falcon Dam to the mouth of the river. Twenty-six (20%) of the locations with maximum concentrations corresponded to portions of Llano Grande Lake and the Arroyo Colorado. Recent analyses of birds and fish indicate that levels of DDE are currently much lower than in the 1970s or 1980s in Rio Grande wildlife. This apparent decline does not apply to Hg and Se levels in birds and fish, which have remained more or less constant, but may have increased over the years in some locations. Hg was of particular concern because of high levels found recently in addled eggs of aplomado falcons and in their potential prey. Hg was elevated in fish from the Big Bend area. Also, Se in fish sampled in 1993 and 1994 was near or above the threshold for potential effects in fish-eating wildlife. Future investigations should evaluate the potential impacts of Hg and Se on aquatic and terrestrial species from selected sites of concern.

Abstract
This study examined the potential for exposure of migratory aquatic birds to contaminants in highly industrialized habitats at Baltimore Harbor, Maryland. Seven nearshore, benthic sites were sampled every 3 or 6 months from June 1987 to December 1988. Twenty metallic elements were measured in composites (i.e. annelids, amphipods, and isopods were pooled), clams, and sediments. Elevated concentrations were widespread throughout the sites, depending on the element. Most concentrations in composites were lowest at sites innermost and outside the harbor. Higher concentrations in composites were not related to season. Most concentrations were higher in composites than in sediments or clams, but they varied by element for clams and sediments. The largest flock of wintering waterfowl frequented the site exhibiting the highest concentrations of most elements ( [Formula: see text] ). Average concentrations of known toxic elements were probably not harmful to aquatic birds or their prey, but the highest detected concentrations of eight elements warrant caution. At least eight other elements exceeded background concentrations, but toxicity to birds or their prey are unknown.
