Counterintuitively, despite the ongoing fuel crisis and the over two decades since the global phaseout of leaded gasoline, toxic lead still lingers in Metro Manila’s air.

Electromagnetic waves are extensively utilized in many fields such as communication and medicine. Excessive electromagnetic waves will cause electromagnetic pollution. Electromagnetic pollution may lead to electromagnetic interference (EMI), which will interfere sensitive electronic devices. Furthermore, electromagnetic pollution is harmful to human health and may potentially cause information leakage. The development of lightweight and flexible EMI shielding materials with high mechanical strength and excellent flame retardant properties is currently a hot and difficult research topic.

As the global population continues to grow and climate change intensifies, agricultural systems are facing unprecedented challenges. To meet food demand, agriculture has long relied on chemical fertilizers and pesticides, but these chemicals not only pollute the environment but also pose potential risks to human health. Meanwhile, crop diseases, particularly those caused by fungi, result in 20%–40% of global yield losses annually, with mycotoxin contamination posing a significant threat to food security.
