Transcript of Gr.11 Chemistry STSE (Arsenic)

Arsenic is a natural heavy metal found in soil, bedrock, and water. It is used to make other metals, glass, electronic components and wood preservatives Arsenic Effects of Arsenic (Children and Adults) Effects of Arsenic on the Environment Effects on Human Health Arsenic does not have a strong ability to build up in the body; Only at high risk levels Symptoms Sore throat
Red skin at contact point
Severe abdominal pain
Vomiting and diarrhea within 1 hour of ingestion More Symptoms Anorexia
Fever
Mucosal irritation
Arrhythmia (condition in which the heart beats with an irregular rhythm) Plants absorb Arsenic very easily, meaning that there may be HIGH concentrations in food Once entered into the environment it is there and cannot be removed or destroyed It is released into the environment during many industrial processes Children may be exposed to Arsenic by the air they breathe, the water they drink, and the food they eat. Since children don't eat and drink a variety of foods and beverages like adults do, ingestion of contaminated food, drinks or baby formula made with arsenic-contaminated water makes exposure in children higher and much more serious Children tend to play in the dirt and then put their hands in their mouths and sometimes they eat dirt, this can lead to the ingestion of contaminated soil and may be an important source of arsenic exposure for children than for adults Children are exposed to arsenic in the same ways that adults are Children who are exposed to arsenic may have many of the same effects as adults If hands are exposed you can get crusty and unhealthy hands like this man Your feet may also get crusty like the mans hands in the picture before THANKS
