A sample from this course

One topic, as StudyPath teaches it.

Environmental components and sample matrices

Environmental sampling hinges on recognising the key environmental components—air, water, soil, sediment, and biota—and the matrices that best represent them for analysis. Mastery of these concepts ensures that samples are collected, preserved and interpreted correctly, a core requirement for NUC CCMAS, NBTE and NCCE exams.
