What Does High Hemoglobin Mean? High hemoglobin levels mean that measured hemoglobin levels are above the upper limits of normal for the age and sex of the person (see above normal values). For example, a 19 year old that has a detected hemoglobin level of above 17.7 g/dl would have a high hemoglobin level.
Some chemical engineers specialize in a particular process, such as oxidation (a reaction of oxygen with chemicals to make other chemicals) or polymerization (making plastics and resins).
Chemical engineers working in laboratories and offices typically work in industries including architectural, engineering-related services, basic chemical manufacturing and scientific research. This type of working environment means standard working hours with days starting between 8 and 9 a.m.
