Soil used for agriculture is seriously contaminated mainly by pesticides and fertilizers, environmental pollutants, heavy metals, sulfuric and nitric acids from acid rain, but also by pollution as well as waste. As a result, pathogenic (disease-causing) substances such as nitrates from fertilizers, pesticides and persistent hydrocarbons enter food and thus the human body through the … Environmental Factors: Soil
Agriculture In southern countries, crop yields are lower than a few years ago. People and diseases Respiratory system Increase in warm climate This will significantly extend the hay fever season (rhinitis allergica).The reason is clear: some pollen will fly earlier – others will fly well into October.In France and Italy, ragweed allergies have already become … Environmental Factors: Consequences of Climate Change
What do infrared rays do? Infrared radiation – IR radiation, also called ultra-red radiation – or thermal radiation refers to electromagnetic waves in the spectral range between visible light and the longer wavelength microwave radiation. This corresponds to a wavelength range of about 780 nm to 1 mm. Short-wave IR radiation (from 780 nm) is … Infrared Radiation
The climate is increasingly changing. The topics global warming and greenhouse effect are our constant companions. Man intervenes significantly in nature, which is not without negative consequences – for people and nature. Overall, temperatures are higher. In summer as well as in winter temperatures are rising and there is less frost in winter. Dry periods … Climate and Climate Change
What facts support anthropogenic – human-caused – climate change? Increase in carbon dioxide (CO2) concentration in the atmosphere since circa 1850 from 280 ppm (pars per million) to 380 ppm by Combustion of fossil fuels (coal, oil, gas, gasoline). Deforestation The current CO2 concentration in the atmosphere is currently 0.04%. CO2 is a climate-altering gas … Environmental Factors: Climate Change
Noise is the term used to describe sounds (sounds; mechanical vibrations) which, due to their structure (usually loudness), can have a disturbing, stressful and/or harmful effect on the environment (in this case: people). Noise is everywhere nowadays. Almost everyone is exposed to noise in everyday life (traffic noise), in their leisure time to sports and … Environmental Factors: Noise
Air is a mixture of gases; it consists mostly of nitrogen (78%) and oxygen (21%). In addition, there are the noble gas argon (0.9%) and carbon dioxide (0.04%), as well as smaller amounts of other substances (e.g. radon* , nitrogen oxides, etc.). * Other sources of radon are drinking water and natural gas; see below … Environmental Factors: Air
Radioactivity is considered to be a cause of tumor diseases, among other things: Radiation from radioactive materials and X-rays can trigger malignant tumors. The energy of this radiation is so great that it can trigger “ionizations” on atoms and molecules, i.e., change their charge and thus, for example, break the bonds that hold molecules together. … Radioactive Radiation
Ultraviolet radiation (UV radiation) is electromagnetic radiation with a wavelength below that of visible light (100 nm to 400 nm), but longer than that of X-rays. Ultraviolet means as much as beyond the violet (Ultra from lat. : beyond). Violet is the visible light with the shortest wavelength. Ultraviolet radiation is no longer perceived by … UV Radiation in Medicine
Under normal or natural circumstances, our groundwater is an ideal drinking water. However, due to human interference with nature, the water table is falling, so drinking water is no longer just groundwater, but also surface water. Surface water and agriculture Surface water contains residues from agriculture – nitrates from fertilizers, pesticides such as pesticides, veterinary … Environmental Factors: Water
The spectrum of electromagnetic radiation is very comprehensive. It includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, and X-rays and gamma rays, among others. The only difference between these types of waves is their frequency and therefore their energy. The guideline of the working group “EMF” of the European Academy of Environmental Medicine … Electromagnetic Radiation
