Environmental Impact
Potassium dichromate is a hazardous substance that can severely damage the environment, especially when released into water sources. It is classified as a pollutant in aquatic ecosystems, and its accumulation can disrupt the food chain and harm aquatic organisms. Therefore, its usage should be monitored, and environmental standards should be strictly followed to prevent contamination.
Applications
- organic synthesis
- chemical industry for producing non-organic pigments, matchmaking, dry cell battery, tannery and fur industry for leather and furtanning. Due to strong oxidizing properties it is widely used in chemistry, photography, pyrotechnics
- in a number of other industries
Safety and Regulations
Due to its toxic and corrosive properties, potassium dichromate must be handled with extreme caution. Direct contact with skin or eyes can cause severe damage. The use of protective equipment, including gloves, safety goggles, and respiratory masks, is mandatory. In case of exposure, immediate washing and medical attention are necessary.
