| Terms for subject Environment (6279 entries) |
| historie prostředí životního | environmental history (A systematic and chronological account of past events and conditions relating to the ecosystem, its natural resources or, more generally, the external factors surrounding and affecting human life) | |
| hladina akustická | acoustic level (Physical quantity of sound measured, usually expressed in decibels) | |
| hladina hluku | noise level (Physical quantity of unwanted sound measured, usually expressed in decibels) | |
| hladina kritická | critical level (General term referring to the concentration limit beyond which a substance can cause dangerous effects to living organisms) | |
| hladina moře | sea level (The level of the surface of the ocean; especially, the mean level halfway between high and low tide, used as a standard in reckoning land elevation or sea depths) | |
| hladina olova v krvi | lead level in blood (A measure of the amount of lead or lead salts absorbed by the body as a possible sign of acute or chronic lead poisoning, which can affect the nervous, digestive or muscular systems) | |
| hladina trofická | trophic level (Any of the feeding levels through which the passage of energy through an ecosystem proceeds; examples are photosynthetic plants, herbivorous animals, and microorganisms of decay) | |
| hladina vodní | water level (The level reached by the surface of a body of water) | |
| hladina vody podzemní | water table (Water that occupies pores, cavities, cracks and other spaces in the crustal rocks. It includes water precipitated from the atmosphere which has percolated through the soil, water that has risen from deep magmatic sources liberated during igneous activity and fossil water retained in sedimentary rocks since their formation. The presence of groundwater is necessary for virtually all weathering processes to operate. Phreatic water is synonymous with groundwater and is the most important source of any water supply) | |
| hladina zvuku | sound level (The sound pressure level (in decibels) at a point in a sound field, averaged over the audible frequency range and over a time interval) | |
| hladomor | famine (A severe shortage of food, as through crop failure or over population. It may be due to poor harvests following drought, floods, earthquake, war, social conflict, etc.) | |
| hlasitost | loudness (The magnitude of the physiological sensation produced by a sound, which varies directly with the physical intensity of sound but also depends on frequency of sound and waveform) | |
| hlavonožec | cephalopod (Exclusively marine animals constituting the most advanced class of the Mollusca, including squid, octopuses, and Nautilus) | |
| hlídka pobřežní | coastguard (A maritime force which aids shipping, saves lives at sea, prevents smuggling, etc. It also responds to emergencies involving oil spills and other discharges at sea and takes the lead in enforcing the law, including assessing penalties for environmental violations) | |
| hliník | aluminium (A light white metal, ductile and malleable, and a good conductor of electricity. It occurs widely in nature in clays and is the third most abundant element in the Earth's crust. It is extracted mainly from bauxite by electrolysis of a molten mixture of purified bauxite and cryolite. The metal and its alloys are used for aircraft, cooking utensils, electrical apparatus, and for many other purposes where its light weight is an advantage. Aluminium became implicated as an environmental health hazard in the 1980s on two counts. Biomedical scientists looking for possible causes of Alzheimer's disease, the premature senility indicated by loss of memory and confusion, found a circumstantial link with aluminium. The theory is a controversial one, Al) | |
| hlinka bělicí | bleaching clay (Clay capable of chemically adsorbing oils, insecticides, alkaloids, vitamins, carbohydrates and other materials; it is used for refining and decolorizing mineral and vegetable oils) | |
| hlodavci | rodents | |
| hlodavec | rodent (Any of the relatively small placental mammals that constitute the order Rodentia, having constantly growing incisor teeth specialized for gnawing) | |
| hluk | noise (Sound which is unwanted, either because of its effects on humans, its effect on fatigue or malfunction of physical equipment, or its interference with the perception or detection of other sounds) | |
| hluk aerodynamický | aerodynamic noise (Acoustic noise caused by turbulent airflow over the surface of a body) |
