It is used in compound with other metals. Its main use is for chrome plating, an industry which is fading as people turn to plastic based alternatives.  Chromium poisoning can occur through breathing in dust, eating, drinking, skin absorption and smoking.  Symptoms include dermatitis, asthma, ulcers, general infection, mucus membrane inflammation, burns on skin, respiratory tract inflammation, conjunctivitis with ulcers and lung cancer.

They were brought in to combat beetles destroying sugar crops in 1935, but the toads ignored the beetles and now threaten many native species by eating what they eat. To travel faster around the country some toads have developed larger hind legs to cover a greater distance before the sun goes down....
