How are samples categorized in the Marine Safety Lab?

Samples in the Marine Safety Lab are categorized as Spill, Source, and Background to effectively manage and analyze the environmental impact of pollutants.

"Spill" samples are collected from areas directly affected by a pollution event, allowing responders to assess the extent of the contamination and the immediate effects on surrounding ecosystems. "Source" samples are taken from potential sources of pollution, such as industrial discharges or runoff areas, to identify the origins of pollutants and contribute to source control efforts. "Background" samples are collected from uncontaminated areas to establish baseline data, which helps in comparing and assessing the degradation caused by pollution.

This categorization is crucial for targeted response strategies and environmental monitoring, ensuring that response efforts are informed and effective. Each category serves a specific purpose in understanding and addressing marine pollution, which is why this answer accurately reflects the practice used in the Marine Safety Lab.
