• Calcium peroxide facilitates to remove the oceanic or lacustrine red tides. By adding 100mg~500mg of calcium peroxide per Liter of water, the occurrence of red tide can be eliminated in 24 hours.

• By coating rice seeding with calcium peroxide, herbicide and plaster of paris, usually 4 kgs calcium peroxide for 24 kgs of rice seeds, yield can be increased by 10% and the cost can be reduced by 50%.

• The harmful CO (carbon oxide) from the lighted cigarette may be greatly reduced when calcium peroxide (amount 0.5%~10%) is added during the manufacturing process. At the smoking rate of 50ml/s, the CO discharging amount of the calcium peroxide blended is remarkably reduced to 2700mg/kg, as compared with the amount of 5000mg/kg discharged by normal cigarette.

• Calcium peroxide is administered to the pigs via the oral route in a proportion of 0.02 to 1.3 % by weight of the total food ration. The percentage of lean meat and the quality of the carcasses are thus substantially improved.

• Calcium peroxide may be used in the detoxification of waste water containing cyanides and/or cyano complexes, heavy metals and sulfides with a substantial effect.
