2/1/2011, · The nitric ,acid, preservative is designed to keep the metallic content of the water sample in solution and in some cases will actually leach metals from the small particles present in the water sample. Thus, filtering a nitric ,acid, preserved water sample and analyzing for ,dissolved, metallic content could produce a high biased result. Reply Delete

Physical water quality parameters were measured, along with heavy metals Cd and Pb. Mean metal levels were consistently low at the wastewater discharge (1.3 μg/L Cd, 5.1 μg/L Pb), and high at the control location (9.2 μg/L Cd and 11.5 μg/L of Pb). Relationships were observed between heavy metals, salinity and pH levels.
