Background information and definitions
Chemicals are often used in agriculture, such as pesticides, herbicides and fertilizers. They are designed to have long-lasting effects on living organisms, are often toxic to non-target species, and as such are a major source of pollution and toxicity in aquatic environments (Jepson et al. 2016). Agricultural run-off, including excess nutrients and toxic substances, can reach rivers and other watercourses and be discharged into the sea. Reducing the use of pesticides, herbicides and fertilizers in agriculture may reduce pollution levels and associated impacts on marine and freshwater mammals.
