Water quality. Biochemical and physiological measurements on fish - Determination of vitellogenin Ingestion-build-1354761 Scope This part of ISO 23893 specifies a method for measuring vitellogenin (Vtg) concentrations in a fish plasma sample employing an enzyme linked immunosorbent assay (ELISA) method. It applies to fish that are sampled in the environment (fresh, estuarine or salt water) and to fish exposed to substances or effluents in a laboratory. The method is quantitative when using Vtg antibodies and a Vtg standard well characterized with the species of choice.

PD ISO/IEC TR 24714-1 gives guidelines for the stages in the life cycle of a system’s biometric and associated elements

two methods can be compared only if the limits of these methods (calculated by using this part of ISO 12828) are similar for the lower range of concentrations to be measured

PD 6689 can also help anyone involved in specifying or delivering UK road surfaces or other trafficked areas to choose products that suit environmental conditions and achieve safer and more durable results that are not over-specified
