The idea of a tooth worm is a theory of the cause of dental caries, periodontitis and toothaches. Once widespread, the belief is now obsolete, having been superseded by more scientific rationales. It was supposed that the disease was caused by small worms resident within the tooth, eating it away. [1]
Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
Researchers looked at rates of tooth decay and hospital admissions for tooth extractions.
Limnodrilus hoffmeisteri is conveyor-belt feeder that ingests particles in deep sediments and egests them on the sediment surface in the form of pseudofeces. [5] [6] The activities of this worm can alter sediment stratification, [6] [7] [8] increase the water content and porosity of sediment, [9] change the distribution of sediment particle size, [6] [10] alter the oxygen and nutrient dynamics ...
When the biological pollution is introduced to an aquatic environment, it contributes to water pollution. Biopollution may cause adverse effects at several levels of biological organization: an individual organism (internal pollution by parasites or pathogens), a population (by genetic change, i.e. hybridization of IAS with a native species),
DEET found to cause reproductive damage in worms, warranting further investigation, scientists say. Katie Hawkinson. January 30, 2024 at 11:31 AM.
This allows water from the ocean to enter into the crust of the earth where it is heated by the magma. The increasing pressure and temperature forces the water back out of these openings, on the way out, the water accumulates dissolved minerals and chemicals from the rocks that it encounters.
Nutrient pollution caused by Surface runoff of soil and fertilizer during a rain storm Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients. It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters ), in which excess nutrients, usually nitrogen or phosphorus ...
