Ammonia is one of the most abundant alkaline gases in the atmosphere. When released into the air, it reacts with acidic compounds to form fine particulate matter known as PM2.5, which contributes to air pollution, climate effects, and human health risks. Identifying where ammonia originates from is essential for designing effective emission control strategies. Researchers have long relied on nitrogen isotope signatures, commonly expressed as δ15N, to distinguish between ammonia released from sources such as fertilizers, livestock waste, and agricultural activities. ...

Excess nutrients such as nitrogen and phosphorus are among the leading causes of water pollution worldwide, fueling harmful algal blooms and degrading aquatic ecosystems.
