Zinc is naturally present in water. The average zinc concentration in seawater is 0.6-5 ppb. Rivers generally contain between 5 and 10 ppb zinc. Algae contain 20-700 ppm, sea fish and shells contain 3-25 ppm, oysters contain 100-900 ppm and lobsters contain 7-50 ppm.

Zinc is one of the most common elements in the earth's crust. It is found in air, soil, and water, and is present in all foods.Pure zinc is a bluish-white shiny metal. Zinc has many commercial uses as coatings to prevent rust, in dry cell batteries, and mixed with other metals to make alloys like brass, and bronze. A zinc and copper alloy is used to make pennies in the United States.

Discussion: Zinc oxide nanoparticles can be synthesized from Aloe vera plant extraction. In small concentration, 0.3 µg/ml, nanoparticles show an antiadhesion effect by reducing flu and fimH gene expression as UPEC's virulence factors. The effectivity and safety of nanoparticles in this concentration have also been proven in vitro.
