It was aimed to determine the median lethal concentrations, growth retardation and developmental malformation effects and the effects of mixed nanoparticle exposure to selected enzyme biomarkers resulting from the exposure of embryos to NPs. The results showed that ZnO NPs, which are the most toxic according to the highest lethality level, cause developmental delay and malformations. The Fe2O3 and TiO2 NPs caused growth retardation only in D. rerio embryos. It was determined that double and triple combinations of NPs did not cause significant lethality in both species. Biochemical markers showed that mixed NPs could lead to greater toxicity compared to single exposures. The results also revealed that TiO2 or Fe2O3 NPs caused an increase in toxicity when co-existing with ZnO NP due to additive effects. Overall, the results showed that D. rerio was more susceptible to NP exposure in terms of growth and mortality than X. laevis. However, studies that are more comprehensive are needed to better understand the toxicity mechanism of metal oxide NP mixtures.","PeriodicalId":9960,"journal":{"name":"Chemistry and Ecology","volume":"39 1","pages":"215 - 234"},"PeriodicalIF":2.5,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43327182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water and sediment samples were taken seasonally from six sites exposed to different anthropogenic impacts. The most enriched elements in the Dam Lake were As, Cd, Mo, and Pb. In all sampling sites, the average heavy metal concentrations indicated low risk except for Cd and Pb which were classified in the moderate ecological risk class. Overall, the ecological risk was low for one site (S3) because of the far distance from the residential areas, while the ecological risk of the other stations was moderate. According to water analysis results, the aquatic life criteria could not be met for Zn, Cu, Cr, and Hg in Süreyyabey Dam Lake. Although the dam lake is used only for irrigation purposes, the Süreyyabey Dam Lake water is not suitable for drinking according to the metal limit values of the World Health Organisation. The results of the current study will contribute to the awareness of local authorities by using several indices on taking the necessary precautions.","PeriodicalId":9960,"journal":{"name":"Chemistry and Ecology","volume":"39 1","pages":"153 - 172"},"PeriodicalIF":2.5,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45572636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, there is a lack of information about the effects of this pollutant on freshwaters making it difficult the conservation of these environments. Benthic species, such as the freshwater amphipod Hyalella azteca, have been superficially studied so far for evaluation of microplastic pollution. In the present study, we analyzed whether polyethylene terephthalate (PET) microplastics could lead to reduced survival of H. azteca or changes in biochemical markers (SOD, CAT, MDA, and GST) at environmentally relevant concentrations (60 and 600 particles) after 7 d of exposure. The results showed that there was no significant mortality at any of the concentrations tested. The enzyme CAT showed no variation compared to the control group at any of the concentrations. SOD, MDA, and GST were statistically different (p < 0.05). Our study demonstrated that PET MP did not affect the survival of H. azteca at environmentally relevant concentrations. However, changes in biomarkers of oxidative stress may be detected at low level of exposure (60 particles). Although survival is not affected, the macrobenthic invertebrate community may be under threat in environments where there is PET microplastic pollution.","PeriodicalId":9960,"journal":{"name":"Chemistry and Ecology","volume":"39 1","pages":"288 - 301"},"PeriodicalIF":2.5,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44432799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sediment samples were collected from five sampling stations and analyzed with an inductively coupled plasma mass spectrometer (ICP-MS).

Element-specific environmental indices exposed that the ecological risks trailed in the same downward direction as Cd > Ni > Pb > As > Cu > Cr. The contamination factor (CF), enrichment factor (EF), and geo-accumulation index (Igeo) exposed all cases to a modest level of contamination except for Cd, which has a significant level of contamination. Only Ni and Cd were found to pose a high ecological risk for aquatic life based on the sediment quality guidelines. The prospective ecological risk factor and potential ecological risk both suggested low to moderate ecological risk. The river sediments were mostly uncontaminated or mildly contaminated, posing a minimal ecological risk.

At present, few studies assessed its effect on the nervous system of zebrafish, especially its sub-chronic toxicity on the zebrafish brain. In this study, the sub-chronic toxicity of broflanilide on the zebrafish brain was assessed. After 21 days of exposure at 36.3 μg/L, broflanilide caused oxidative damage to the zebrafish brain, increased the levels of reactive oxygen species and malondialdehyde, and inhibited the activities of superoxide dismutase, catalase, and glutathione peroxidase. Overall, these changes result in brain cell apoptosis, and inhibited growth and development. Moreover, broflanilide affects the release of acetylcholinesterase, γ-aminobutyric acid, 5-hydroxy tryptamine, and dopamine as well as the expression of related genes in the brain, leading to abnormal zebrafish behaviour. These results corroborate the sub-chronic toxicity of broflanilide on zebrafish brain, which helps the further understanding of the potential environmental risk of broflanilide.","PeriodicalId":9960,"journal":{"name":"Chemistry and Ecology","volume":"39 1","pages":"137 - 152"},"PeriodicalIF":2.5,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45058047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When 20 years ago a new Editor in Chief was appointed, the main target of the journal was to widen its visibility and to acquire the impact factor. These results were achieved and during the last 10 years, Chemistry and Ecology has constantly expanded its visibility in the international community and, coherently, has increased its Impact Factor (source ISI-Web of Science), attracting and growing number of submissions from several academia and research institutes worldwide. The papers published in Chemistry and Ecology are becoming an important reference for research based on multi-disciplinary approaches in aquatic and terrestrial ecosystems dealing with environmental pollution, ecotoxicology, environmental biotechnology and biogeochemistry. The Journal is also experiencing an enormous increase in flow of manuscripts and more than 600 papers have been published 10 years with 10 issues per year. In addition, Chemistry and Ecology continues to publish also specific issue on emerging topics, such as the SI dedicated to the ABBaCO project and entitled: Multidisciplinary approach to the characterisation of marine coastal areas subjected to chronic industrial contamination. The manuscripts’ flow has also increased over time reaching more than 280 submissions per year, while having space only for 60 publications per year. According to the journal procedure and the policy of Taylor & Francis group, each issue has been published online once completed (ca 6 papers) and hard copies of the journal are now published in two volumes collecting the issues 1–5 and 6–10, to reduce the impact of the Journal production and management on the environment. Some papers resulted highly cited. These manuscripts covered various topics, from the bioremediation solutions, the application of new environmental biotechnologies [1–13], the ecotoxicological research on aquatic and terrestrial organisms [14–18], the assessment of different pollution sources along with the biological responses [19–37], and the organic matter diagenesis and biogeochemical cycles in all ecosystems [38–44]. These results are due to its growing international credibility, the engagement of a growing number of authors (more than 2500 in the last 10 years have published in Chemistry and Ecology), the contribution of the Editorial staff and Editorial board, and of the &gt;1600 reviewers that have dedicated their time to support the growth of Chemistry and Ecology in the last 10 years. We will continue in this direction, guaranteeing the full respect of equity and accessibility of the journal, the gender balance, fair and robust review process, and the support to young and emerging scientists all over the world, independently from the prestige of their institution, giving voice to all Authors with an original vocation to publish their original results from all o","PeriodicalId":9960,"journal":{"name":"Chemistry and Ecology","volume":"38 1","pages":"897 - 899"},"PeriodicalIF":2.5,"publicationDate":"2022-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46383740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine metal accumulation and the sources of air metallic pollution in the Safi urban-industrial area using lichens as biomonitors. Ten trace elements (As, Cd, Co, Cr, Cu, Ni, Pb, Ti, V and Zn) concentrations and 206Pb/207Pb and 208Pb/207Pb isotopic ratios were analyzed by ICP-MS in four lichen species: Xanthoria Parietina, Ramalina Lacera, Xanthoria Calcicola and Ramalina Pollinaria. The results showed significant differences among study sites for most elements with higher concentrations in the industrial, urban and peri-urban sites compared to the reference site chosen as a natural rural area far from any human activities. Significant differences were found between saxicolous and corticolous species especially for Cd, Cu and Zn. The values of Zn/Cu, Zn/Pb and Pb isotope ratios measured in lichens revealed that vehicular traffic and industrial emissions are the main sources of atmospheric Pb contamination. Other anthropic activities (waste incineration, artisanal pottery …) might be the source of other trace metal elements accumulated by lichens. Airborne contaminants in Safi appear to be exported from their sources by air mass movements driven by the regional wind profile.","PeriodicalId":9960,"journal":{"name":"Chemistry and Ecology","volume":"39 1","pages":"107 - 122"},"PeriodicalIF":2.5,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46017714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
