Article Synopsis
- - The study examines the effects of bisphenol F (BPF) and bisphenol AF (BPAF) on neurodevelopment and pancreatic cell differentiation in zebrafish embryos, focusing on changes in DNA methylation and gene expression.
- - Zebrafish exposed to BPF and BPAF showed significant behavioral changes, increased glucose levels, and decreased insulin-related gene expression, indicating potential developmental disruptions.
- - Findings revealed increased DNA methylation in specific genes linked to development and insulin production, suggesting that exposure to these bisphenols leads to islet dysfunction and neurodevelopmental issues in early-stage zebrafish.
There is a growing recognition that activities at automobile mechanic shops could contribute to heavy metal contamination of soils. This study seeks to evaluate the ecological and human risk assessments of heavy metal contamination of surface soils of auto-mechanic shops at Bogoso Junction, Tarkwa, Ghana. Herein, 20 composite soil samples were taken, acid-digested, and the concentrations of Cu, Pb, Cd, Mn, Ni, Cr, and Fe were measured using a flame atomic adsorption spectrometer (SHIMADZU, AA 7000).

Eighty soil samples were collected, and metal concentrations were determined using atomic absorption spectroscopy (AAS). The results revealed that Cu, Ni, Pb and Zn concentrations exceeded the WHO/FAO (2001) standard in some areas.
