One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.

Preservatives are another type of additive worth scrutinizing. While they prolong the shelf life of food, some preservatives can have adverse health effects. For example, sodium nitrite, commonly used in cured meats, has been linked to an increased risk of certain cancers when consumed in large amounts. Similarly, BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are used to prevent oxidation in fats and oils, but studies suggest they may be carcinogenic. Opting for fresher, less processed food often means steering clear of these potential hazards.
