Because corrosion is a diffusion-controlled process, it occurs on exposed surfaces. As a result, methods to reduce the activity of the exposed surface, such as passivation and chromate conversion, can increase a material's corrosion resistance.
Foodborne Illnesses Definition: A foodborne illness is an infection or poisoning caused by a bacterium, virus, parasite, or chemical transmitted by food. A foodborne outbreak is an illness event that typically includes two or more people infected from a common food source.
Water-borne diseases are any illness caused by drinking water contaminated by human or animal faeces, which contain pathogenic microorganisms. The full picture of water-associated diseases is complex for a number of reasons. Over the past decades, the picture of water-related human health issues has become increasingly comprehensive, with the emergence of new water-related infection diseases and the re-emergence of ones already known.
