The review analyzes the existing PFAS monitoring, the accessibility of MS instruments, and the technical capabilities within the continent. This study suggests that fewer African countries have sufficient MS instruments, resulting in significant underreport of environmental data and related public health issues. The review proposes financial support and programs to address these difficulties to provide necessary MS instruments. The review suggests that it is highly important to develop regional centers of excellence for PFAS monitoring using MS instruments and investing in training programs to address the gap in monitoring efforts.

A total of 155 urine samples from fish smokers across selected coastal regions in Ghana were collected and analyzed.

Understanding the intricate relationships among these variables is critical for shaping adequate energy and environmental policies in the context of China's growing role as a global economic power. The empirical methodology utilizes time-series data from 2000 to 2023 and applies econometric techniques, including Autoregressive Distributed Lag (ARDL).

In the short term, there is bidirectional causality between energy utilization and economic growth, indicating mutual feedback between energy demand and economic development. POP growth and trade activities also significantly influence energy utilization patterns and emissions. The policy implications are profound: China must prioritize promoting RC, enhancing energy efficiency, and strengthening environmental regulations to decouple economic growth from environmental degradation.
