Non-communicable diseases (NCD) constitute one of the highest burdens disease globally and are associated with inflammatory responses in target organs. There is increasing evidence significant human exposure to micro- nanoplastics (MnPs). This review environmental MnP health impacts indicates that particles, directly indirectly through their leachates, may exacerbate inflammation.

Bisphenol A alternatives are manufactured as potentially less harmful substitutes of bisphenol (BPA) that offer similar functionality. These already in the market, entering environment and thus raising ecological concerns. However, it can be expected levels BPA will dominate future, they limited information on their environmental safety. The EU PARC project highlights priority chemicals consolidates alternatives, with a focus relevance identification research gaps. review highlighted aspects future perspectives. In brief, an extension monitoring is crucial, extending to cover track facilitate timely implementation mitigation measures. biological activity has been studied for but non-systematic way prioritized number chemicals. For several data provided substantial evidence regarding potential harm environment. We stress importance conducting more comprehensive assessments go beyond traditional reproductive studies overlooked relevant endpoints. Future should also consider mixture effects, realistic concentrations, long-term consequences biota ecosystems.

Beyond microbeads: Examining the role of cosmetics in microplastic pollution and spotlighting unanswered questions

Journal of Hazardous Materials, Journal Year: 2024, Volume and Issue: 476, P. 135053 - 135053

Published: June 27, 2024

The presence of microplastics in cosmetics and personal care products (C&PCPs) has been increasingly the public eye since early 2010s. Despite increasing research into potential environmental health effects microplastics, most to date on C&PCPs investigated "rinse-off" products, while impacts "leave-on" have largely neglected, despite these being purchased greater volumes often having two or more microplastic ingredients their formulations(CosmeticsEurope, 2018b). This review aims synthesize current knowledge C&PCPs, assessing human discussing regulatory implications. lack studies leave-on is significant, suggesting a severe gap regarding in, emissions from, C&PCPs.

Emissions from corrosion protection systems of offshore wind farms: Evaluation of the potential impact on the marine environment

Marine Pollution Bulletin, Journal Year: 2018, Volume and Issue: 136, P. 257 - 268

Published: Sept. 20, 2018

Offshore wind energy is a fast growing sector of renewable energies worldwide. This will change the marine environment and thus, wide range environmental impacts offshore farms are subject current research. Here we present an overview about chemical emissions from corrosion protection systems, discuss their relevance potential impact to environment, suggest strategies reduce emissions. Corrosion general problem for infrastructures systems necessary maintain structural integrity. These often in direct contact with seawater have different potentials emissions, e.g. galvanic anodes emitting substantial amounts metals. Organic coatings may release organic substances due weathering and/or leaching. Current assumptions suggesting low impact, but monitoring data not sufficient assess this new source.

Bisphenol F (BPF) and bisphenol S (BPS) are increasingly used as substitutes for A (BPA), an environmental obesogen. However, health effects of BPF BPS remain unclear. In this study, we evaluated the associations BPA, BPF, with obesity in children adolescents.We data from U.S. National Health Nutrition Examination Survey 2013 to 2014, a nationally representative study.

Adverse effects in the fish embryo acute toxicity (FET) test: a catalogue of unspecific morphological changes versus more specific effects in zebrafish (Danio rerio) embryos

Environmental Sciences Europe, Journal Year: 2020, Volume and Issue: 32(1)

Abstract Background The Fish Embryo Acute Toxicity (FET) test with the zebrafish ( Danio rerio ) embryo, OECD guideline (TG) 236, has been designed as an alternative for acute fish toxicity testing such Test (TG 203). To provide equivalent sensitivity to test, original FET was use only four morphological core endpoints: coagulation of lack somite formation, heart beat, and non-detachment tail. These endpoints were selected due (1) their association mortality, directly or indirectly, (2) improve practicality screening by well-trained technical staff, (3) being relatively simple alterations. Results With growing need understand developmental compounds found in environment, protocol repeatedly extended a multitude additional that also allow monitoring teratogenicity. As extensive generated observations scientific literature, harmonisation terminology used description effects seen after chemical exposure become necessary. Conclusion For this end, present communication provides overview both common more specific embryos wide variety substances together suggestions harmonised nomenclature.
