Bisphenols and Phthalates in Bottled Mineral Water: First Evidence of Co‐Occurrence, Estrogenic Activity, and Health Risk in Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), its structural analogs, and phthalates are synthetic chemicals widely used, with documented endocrine‐disrupting activity. This study aimed to develop and validate a selective multiresidue analytical method for the simultaneous determination of BPA, 10 bisphenol analogs, and six phthalates in PET‐bottled mineral water.

Native electrospray ionization mass spectrometry reveals the interaction variances between different bisphenol analogues and myoglobin

Results in Chemistry
Bisphenol analogues (BPs) are crucial industrial materials extensively utilized in the production of consumer goods. However, it is still unknown whether they will affect the structure of myoglobin (Mb) and cause adverse impacts.

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Impact of bisphenol A, F, AF, C, and S on rumen ecology: an exploratory in vitro screening

Italian Journal of Animal Science
Ruminants consume significant quantities of biomass, representing a primary pathway for xenobiotic exposure due to pollutant accumulation in plants. This exploratory in vitro screening aimed to evaluate the short-term impact of bisphenol A (BIS_A) and ...

Influence of Octaglycidyl‐POSS on Processing Behavior, Gelation Kinetics, and Thermomechanical Properties of a DGEBA/Polyamidoamine Epoxy System

Journal of Vinyl and Additive Technology, EarlyView.
The rigid, octafunctional Si8O12 cage of OG‐POSS incorporates into the DGEBA/polyamidoamine network as a multifunctional junction, raising the glass transition temperature (Tg) by up to 19°C and the apparent crosslink density non‐monotonically by 47%‐71% at 1.5, 3.0, and 5.0 phr loading.

The External Exposome and Food Allergy: How Environmental Exposures Shape Disease Risk

Allergy, EarlyView.
ABSTRACT IgE‐mediated food allergy is a global health issue with rising prevalence that cannot be explained by genetic change alone, strongly suggesting that environmental exposures are a key driver. The external exposome encompasses several exposures that influence the developing immune system and modify food allergy risk.

Toward a Politics of (In)Fertility: Reproductive Debility in Africa

American Anthropologist, EarlyView.
ABSTRACT Sub‐Saharan Africa has some of the highest estimated rates of infertility or involuntary childlessness in the world, leading epidemiologists to refer to parts of the region as the “infertility belt.” The medicalization of infertility and the situating of assisted reproductive technologies (ARTs) as the treatment for infertility have siphoned ...
