OSHA standards prohibit worker exposure to more than 50 parts of CO gas per million parts of air averaged during an 8-hour time period. • The 8-hour PEL for CO in maritime operations is also 50 ppm. Maritime workers, however, must be removed from exposure if the CO

Electrical Conductivity/Salinity Fact Sheet
www.waterboards.ca.govwater). The results are usually expressed in grams/liter (g/l) or parts per thousand (ppt) for sea water (Pacific Ocean water are around 32 g/l in winter). In freshwater the term “total dissolved solids” (TDS) is often used for the same thing instead of “salinity”. Useful TDS units are milligrams/liter (mg/l) or parts per million (ppm).

UNITS OF CONCENTRATION - Vancouver Island University
web.viu.caConcentrations expressed as ppm and N are less familiar to most students at this stage. Parts per million: The number of milligrams of solute per kg of solution = one ppm, since 1 mg = 10-3 g and 1 kg = 103 g. Assuming the density of water is 1.00 g/mL, 1 liter of solution = 1 kg and hence, 1 mg/L = 1 ppm.
