The examination for the detection of congenital anomalies is referred to as either detailed ultrasound study or targeted imaging for fetal anomalies (TIFFA) 3, 4 In such examinations, a variety of fetal anatomic views (âtargetsâ') are specifically sought after and imaged by experienced ultrasonographers.
Turbidity is measured in NTU: Nephelometric Turbidity Units. The instrument used for measuring it is called nephelometer or turbidimeter, which measures the intensity of light scattered at 90 degrees as a beam of light passes through a water sample.
Turbidity is commonly linked to total suspended solids (TSS) because water with high TSS levels typically look murkier and have higher turbidity measurements. Common suspended solids are clay, silt, and sand from soils, phytoplankton (suspended algae), bits of decaying vegetation, industrial wastes and sewage.easuring turbidity in streams is an important indicator of the concentration of suspended sediments in the water. Sediments are a natural part of streams and other water bodies and even the most pristine streams in undeveloped watersheds will run muddy during high flows.
