Ten different types were tested, including five spherical AuNPs with various sizes (50, 80, 100, 200, and 400 nm) and five shapes of AuNPs (cube, hexagon, bean, rod, and tetrapod). After catalase conjugation to AuNPs, optimum size and shape were selected by the highest uptake of AuNPs by macrophages.

One milligram per liter of ammonia-nitrogen is equivalent to 1.22 mg/L of ammonia., Confusion on this can result in reporting an ammonia violation when, in fact, there may not be a violation at all. The next article will deal with the other forms of nitrogen that we are concerned with in the wastewater field: nitrate, nitrite, and organic nitrogen.
