To elucidate the dynamics of mercury emitted and released by artisanal and small-scale gold mining (ASGM) activity and to estimate its impact on the ecosystems of the bay, the distribution of mercury in the atmosphere, soil, water, and sediment around Mambulao Bay, Camarines Norte, Philippines, was investigated. The ASGM operations use mercury to extract gold from ore and are located on the east shore side of the bay. Samplings were conducted in August 2017 and September 2018.

Article Synopsis
- - The study highlights how environmental exposure to active pharmaceutical ingredients (APIs) can harm ecosystems and human health, indicating the need for a comprehensive assessment of this global issue.
- - Conducted across 258 rivers in 104 countries, the research found notably high levels of API contamination in sub-Saharan Africa, South Asia, and South America, often linked to poor waste management and pharmaceutical production practices.
- - Over 25% of the sampling sites had API concentrations exceeding safe levels for aquatic life, raising concerns about environmental risks and the potential for increased antimicrobial resistance, which threatens progress toward the United Nations Sustainable Development Goals.

The natural abundance of Cr and Ni in serpentine soils is well-known, but the food safety of rice grown in these hazardous paddy soils is poorly understood. The study evaluated the bioaccumulation of chromium (Cr) and nickel (Ni) in rice (Oryza sativa) grown in serpentine-derived paddy soils in the Philippines. Surface soil (0-20 cm) samples were collected and characterized across three (i.
