During the urbanization, human activities have brought great changes to marine biodiversity and microbial communities of coastal water. Shenzhen is a coastal city that has developed rapidly over the past four decades, but the microbial communities and metabolic potential in offshore water are still not well characterized. Here, 16S rRNA gene V4-V5 sequencing was conducted to determine the microbial

Comparative acute toxicity of benzophenone derivatives and bisphenol analogues in the Asian clam Corbicula fluminea Ecotoxicology. (IF 2.535) Pub Date : 2020-11-07 Marta Seoane, Ángeles Cid, Concepción Herrero, Marta Esperanza
Among UV-filters, benzophenones are one of the most abundantly used and detected groups in the environment. Bisphenols are also one of the most widely used chemicals in plastics, but their demonstrated deleterious effects on several organisms and humans have led to the production of alternative analogues. However, few comparative studies on the ecotoxicological effects of these derivatives or analogues

Multi-metal tolerance of DHHC palmitoyl transferase-like protein isolated from metal contaminated soil Ecotoxicology. (IF 2.535) Pub Date : 2020-11-06 Arkadeep Mukherjee, Bharti Thakur, Ajay Kumar Pandey, Roland Marmeisse, Laurence Fraissinet-Tachet, M. Sudhakara Reddy
The microbiota inhabiting in metal polluted environment develops strong defense mechanisms to combat pollution and sustain life. Investigating the functional genes of the eukaryotic microbiota inhabiting in these environments by using metatranscriptomics approach was the focus of this study. Size fractionated eukaryotic cDNA libraries (library A, < 0.5 kb, library B, 0.5-1.0 kb, and library C, > 1

A review of metal-induced effects on vitamins A, E and D3 in birds Ecotoxicology. (IF 2.535) Pub Date : 2020-11-05 Silvia Espín, Pablo Sánchez-Virosta
Birds have been historically affected by metals and are considered powerful sentinels of environmental pollution. Some toxic elements (Pb, Cd, Hg, As) have been broadly studied in avian species and are well known for their accumulation capacity and deleterious effects, including alterations in vitamin levels. Vitamins A, E and D3 are fat-soluble nutrients involved in multiple physiological functions

Phosphorus fertilization and mycorrhizal colonization change silver nanoparticle impacts on maize Ecotoxicology. (IF 2.535) Pub Date : 2020-11-03 Fayuan Wang, Ke Li, Zhaoyong Shi
Environmental risks of silver (Ag) nanoparticles (NPs) have aroused considerable concern, however, their ecotoxicity in soil-plant systems has yet not been well elaborated, particularly in agroecosystems with various fertility levels and soil biota. The aims of the present study were to determine AgNPs impacts on maize as influenced by mycorrhizal inoculation and P fertilization. A greenhouse pot experiment

Release characteristics of inorganic nitrogen in different water layers and its impact on overlying water from Liaohe River, China Ecotoxicology. (IF 2.535) Pub Date : 2020-11-01 Chen Qiuying, Wang Qi, Li Zhidong, Zhang Mingwei, Sun Manzhong
Migration and release of sediment pollutants has become one of the important causes of water pollution, but the contribution of different forms of nitrogen in different water layers to the water quality of the overlying water is unclear. In this study, the main stream of Liaohe River with heavy nitrogen pollution was taken as an example. The static simulation method and related analysis techniques

Spatiotemporal variations and risk assessment of ambient air O 3 , PM 10 and PM 2.5 in a coastal city of China Ecotoxicology. (IF 2.535) Pub Date : 2020-11-01 Lichao Wang, Liqun Xing, Xiankun Wu, Jie Sun, Ming Kong
Rapid industrialization and urbanization has created significant air pollution problems that have recently begin to impact the lives and health of human beings in China. This study systematically investigated the spatiotemporal variations and the associated health risks of ambient O3, PM10 and PM2.5 between 2016 and 2019. The relationships between the target air pollutants and meteorological conditions

Deterministic risk assessment of firefighting water additives to aquatic organisms Ecotoxicology. (IF 2.535) Pub Date : 2020-08-31 S. Graetz, M. Ji, S. Hunter, P. K. Sibley, R. S. Prosser
Past firefighting water additives were found to contain perfluorinated compounds that could persist in the environment resulting in potential adverse effects to biota. Since this revelation, manufacturers have introduced alternative firefighting water additives that are fluorine free, but few studies have investigated the fate and effects in the environment of these new additives. Firefighting water

Side effects of a mixture of essential oils on Psyttalia concolor Ecotoxicology. (IF 2.535) Pub Date : 2020-08-27 Thiago J. S. Alves, Ana Murcia-Meseguer, Celeste Azpiazu, Andrea Wanumen, Valéria Wanderley-Teixeira, Álvaro A. C. Teixeira, Antonio Ortiz, Pilar Medina
Integrated Pest Management programs do not always prioritize natural enemies when selecting control methods; too often these important pest reducing agents are negatively affected by the action of other methods in agroecosystems. The aim of this research was to evaluate side effects of a bioinsecticide, developed from the mixture of cedar (Cedrus atlantica), eucalyptus (Corymbia citriodora) and lemon

Effects of the antidepressant fluoxetine on pigment dispersion in chromatophores of the common sand shrimp, Crangon crangon : repeated experiments paint an inconclusive picture Ecotoxicology. (IF 2.535) Pub Date : 2020-08-28 Alex T. Ford, Eleanor Feuerhelm
The effects of antidepressants in the environment are starting to generate considerable interest due to the fact that neurotransmitters influence a range of biological processes. Crypsis is an important behavioural and physiological response in many crustaceans modulated by monoamine and pigment dispersing/concentrating hormones. This study aimed to develop a test methodology and investigate the effects
