The main water pollutants are:
- Sewage and other oxygen demanding wastes (mostly organic matter, whose decomposition produces oxygen depletion).
- Infectious agents.
- Plant nutrients that can stimulate the growth of aquatic plants. These, in turn, interfere with the uses to which water is intended and, when decaying, deplete dissolved oxygen and produce unpleasant odors.
- Chemicals, including pesticides, various industrial products, surface-active substances contained in detergents, and products of the decomposition of other organic compounds.
- Petroleum, especially from accidental discharges.
- Minerals and inorganic chemicals.
- Sediments consisting of soil and mineral particles carried by the storms and runoff from farmland, unprotected soils, mining, roads and urban demolition.
- Radioactive substances from the waste produced by mining and refining of uranium and thorium, nuclear power plants and industrial use, medical and radioactive materials scientist.

A team led by researchers from the Consejo Superior de Investigaciones Científicas (CSIC) has identified a relationship between body weight and composition of the gastrointestinal microflora. The work, published in the journal Obesity, suggests that the intestinal microflora contributes to the body's energy supply and its influence on the regulation of body weight. The results may encourage the design of new strategies to combat obesity.

CSIC researcher Yolanda Sanz, Institute of Agrochemistry and Food Technology, explains: "These new research on the relationship between specific components of the intestinal microflora, lifestyle and body weight regulation may be key in advancing the development of new strategies for nutritional intervention to contribute more effectively to prevent obesity and associated metabolic diseases by modulating the composition of the flora.

A study led by the Consejo Superior de Investigaciones Científicas (CSIC) has determined that different neurons in the tactile system variables to encode the same stimulus. These results, published this week in the journal Neuron, mark a further step in understanding the dialogue between the thalamus and the cerebral cortex involved in the
perception of the environment.

The purpose of the study on the system of touch Vibrissae (whiskers) of mice, was to determine the nature of the information encoded tactile neurons in the ventral posterior half nucleus of the thalamus (VPM). This region is the cortex that sends the main messages about touch mediated by Vibrissae. As the researcher Miguel Maravall CSIC, one of the directors of the study, we demonstrated that each neuron is encoding a different type of information, which implies a source richer, more flexible, allowing the bark to convey a message much more complex.
