Exposure Impacts of Environmentally Relevant Concentrations of a Glufosinate Ammonium Herbicide Formulation on Larval Development and Thyroid Histology of Xenopus laevis. Arch. Environ. Contam. Toxicol. (IF 2.4) Pub Date : 2020-09-18 Oluwaseun O Babalola,J Christoff Truter,Edward Archer,Johannes H van Wyk
Thyroid hormones play critical roles in body growth and development as well as reproduction. They also influence the activities of a wider variety of tissues and biological functions, such as osmoregulation, metabolism, and especially metamorphosis in organisms, such as frogs. These complex activities of thyroid hormones are prone to disruption by agricultural pesticides, often leading to modulation

The purpose of this study was to investigate the association among polycyclic aromatic hydrocarbons (PAHs) exposure and air pollutants and the diversity of microbiota. Daily average concentrations of six common air pollutants were obtained from China National Environmental Monitoring Centre. The PAHs exposure levels were evaluated by external and internal exposure detection methods, including monitoring

The Moss Biomonitoring Method and Neutron Activation Analysis in Assessing Pollution by Trace Elements in Selected Polish National Parks. Arch. Environ. Contam. Toxicol. (IF 2.4) Pub Date : 2020-09-08 Grzegorz Kosior,Marina Frontasyeva,Zbigniew Ziembik,Inga Zincovscaia,Agnieszka Dołhańczuk-Śródka,Barbara Godzik
The concentrations of trace elements in feather moss Pleurozium schreberi (Brid.) Mitt. were used to indicate the relative levels of air pollution by trace elements in Polish national parks. Pleurozium schreberi was collected from nine national parks. The highest concentrations were recorded in the moss samples from the southern and most industrialised part of the country; the lowest from northern

Lethal and Teratogenic Impacts of Imazapyr, Diquat Dibromide, and Glufosinate Ammonium Herbicide Formulations Using Frog Embryo Teratogenesis Assay-Xenopus (FETAX). Arch. Environ. Contam. Toxicol. (IF 2.4) Pub Date : 2020-09-08 Oluwaseun Olusegun Babalola,Johannes Christoff Truter,Johannes Hannes Van Wyk
Globally, amphibians are experiencing widespread abnormalities and population declines. One potential contributor to these challenges is the use of pesticides, particularly aquatic herbicides applied to aquatic habitats inhabited by amphibians. Critical issues of concern are the potential toxicity and teratogenicity of these herbicides towards amphibians. Using the FETAX protocol, three globally used

Analysis of Trace Element Concentrations and Antioxidant Enzyme Activity in Muscle Tissue of the Atlantic Sharpnose Shark, Rhizoprionodon terraenovae. Arch. Environ. Contam. Toxicol. (IF 2.4) Pub Date : 2020-08-31 Rachel Somerville,Maya Fisher,Louise Persson,Samantha Ehnert-Russo,James Gelsleichter,Gretchen Bielmyer-Fraser
Metals occur naturally in the environment; however, anthropogenic practices have greatly increased metal concentrations in waterways, sediments, and biota. Metals pose health risks to marine organisms and have been associated with oxidative stress, which can lead to protein denaturation, DNA mutations, and cellular apoptosis. Sharks are important species ecologically, recreationally, and commercially

Life-History Traits Response to Effects of Fish Predation (Kairomones), Fipronil and 2,4-D on Neotropical Cladoceran Ceriodaphnia silvestrii. Arch. Environ. Contam. Toxicol. (IF 2.4) Pub Date : 2020-08-28 Raquel Aparecida Moreira,Odete Rocha,Thandy Junio da Silva Pinto,Laís Conceição Menezes da Silva,Bianca Veloso Goulart,Cassiana Carolina Montagner,Evaldo Luiz Gaeta Espindola
Aquatic environments are constantly exposed to a cocktail of contaminants mainly due to human activities. As polluted ecosystems may simultaneously present other multiple natural stressors, the objective of the present study was to evaluate joint effect of stressors (natural and anthropogenic) on life history traits of the Neotropical cladoceran, Ceriodaphnia silvestrii. For this purpose, the effects

Condition and Sperm Characteristics of Perch Perca fluviatilis inhabiting Boreal Lakes Receiving Metal Mining Effluents. Arch. Environ. Contam. Toxicol. (IF 2.4) Pub Date : 2020-07-21 Juha Karjalainen,Hanna E Arola,Jaana Wallin,Ari Väisänen,Anna K Karjalainen
One of the world’s largest, but low-grade, sulfide nickel deposits in northeastern Finland has been exploited by a bioheapleaching technology since 2008. Bioheapleaching is a relatively new, cost-effective technology, but humid climate, e.g., in boreal temperate environments, causes challenges to the management of the water balance in the ore heaps with wide catchment area, and the mining effluents

Annual Characteristics, Source Analysis of PM1-Bound Potentially Harmful Elements in the Eastern District of Chengdu, China. Arch. Environ. Contam. Toxicol. (IF 2.4) Pub Date : 2020-07-15 Jinjin Wang,Yi Huang,Ting Li,Huibin Shi,Min He,Xin Cheng,Shijun Ni,Chengjiang Zhang
Chengdu, a megacity in southwestern China, experiences severe air pollution; however, knowledge of the seasonal variation in mass concentration, extent of potentially harmful elements (PHEs) contamination, and sources caused by heavy metals remains lacking. This study adopted a weighting method to calculate the daily mass concentration of PM1 and used ICP-MS to determine PHE concentrations. Results

(IF 2.4) Pub Date : 2020-07-14 John B Chiari,Jacob M Laperche,Roshni Patel,Nicole March,Gabriella Calvitto,Harry M Pylypiw,Courtney L McGinnis
Phenothiazine (PTZ) is a heterocyclic thiazine compound used for industrial and medical purposes. Through environmental surveillance studies, PTZ was found being discharged into a local river in Connecticut. Phenothiazine has been shown to act similarly to endocrine disrupting chemicals. This study sought to identify sex specific hormone receptor changes in Fundulus heteroclitus in response to PTZ
