NATA Accredited Laboratories of Envirolab are Now Testing For Arsenic Speciation in Water and Urine


The Melbourne office of Envirolab Services is pleased to announce that arsenic testing and analysis of waters and urine is now available at the NATA accredited laboratories of Envirolab Group.  

Found as a natural element in the earth’s crust, arsenic is widely distributed in the environment through air, water and land. Arsenic occurs in the environment in an organic and inorganic form. Less toxic, organic arsenic may occur naturally in different types of foods that include seafood, meat, poultry and cereal products. Once ingested, this organic form of arsenic is quickly eliminated by the body.

Inorganic forms of arsenic, such as arsenate and arsenite can be highly toxic and may have particularly adverse health effects. Found naturally in soil and rock, the entry of wind-blown dust may cause inorganic arsenic to contaminate water supplies including groundwater, creeks, rivers, dams or bores and reservoirs. Contamination may also occur through industrial operations including mining and smelting. Erosion of natural deposits and natural disasters including bush fires, major storms and flooding may also lead to inorganic arsenic contaminating water supplies.

Once inorganic arsenic has entered sources of water supply, exposure may occur through the activities of drinking contaminated water. Exposure to inorganic arsenic may also occur through other activities, such as preparing food with contaminated water or consuming food that has been irrigated with contaminated water.

Due to its high level of toxicity, inorganic arsenic has been used for preserving and protecting wood against insects including termites, bacteria and fungi. Examples of the different types of wood treated by arsenic containing products may include decks, building foundations, fences, playground material and generally wood that has been protected from decay. Arsenic has also been used in pesticides, poisons and weed killers.

Our fact sheet on arsenic speciation in water and urine prepared by Envirolab Services provides you with a guide and instructions on collecting samples for the analysis or arsenic.
