Deriving the freshwater quality criteria of BPA, BPF and BPAF for protecting aquatic life

Ecotoxicology and Environmental Safety

Abstract

Bisphenol A (BPA) has been recognized by the European Chemicals Agency (ECHA) as an endocrine disruptor, and its use in thermo paper has been restricted from 2020 under the Regulation concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH). However, substances with similar structures such as bisphenol F (BPF) and bisphenol AF (BPAF) are widely used as BPA substitutes and commonly detected in aquatic environments. In this study, the water quality criteria of BPA, BPAF and BPF for protecting the aquatic life were derived to provide safety thresholds for their environment risk management. To accomplish this, the species sensitivity distribution (SSD) method was applied based on ecotoxicity data available in the literature and the supplementary toxicity test results for BPF and BPAF towards Marisa cornuarietis, Chironomus tentans and Scenedesmus obliquus. When compared with BPF, BPAF was found to be more acutely and chronically toxic to Marisa cornuarietis, Chironomus tentans and Scenedesmus obliquus, among which Chironomus tentans showed the most sensitivity. The criteria maximum concentrations (CMCs) of BPA, BPF and BPAF were derived to be 520, 227, and 43.4 μg‧L-1, while the criteria continuou...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
