3. HARJUTUSÜLESANNE 3.1. Harjutusülesanne "Autori otsing" Nobeli preemia keemia alal anti 2001. aastal uurimistööle "Discovery and development of conductive polymers". Üks auhinna saajatest oli Alan G. MacDiarmid. Leia: a) mitu artiklit avaldas ta aastatel 1975 - 1985? 67 artiklit b) kuidas leidsid vajalikud andmed? Sisestasin autori nime. Seejärel kuvati ekraanile igasuguseid variante, millest valisin nime Alan G. MacDiarmid. Seejärel klõpsasin ,,Publication years 1975- 1985. Sain 67 vastet. c) mitu tööd sisaldasid kontseptsiooni "conducting polymers" või "plastics"? 183 tööd d) kuidas leidsid need tööd? Tuli refine'i alt valida research topics, sisestasin otsisõnadeks "conducting polymers" or "plastics" . e) mitu patenti on Alan G. MacDiarmid nimel? 26 f) kuidas leidsid vajalikud andmed. Tuli refine'i alt valida ,,document type" ning klikata patent'i peal. Juhised ülesande lahendamiseks leiad : How to...

Article 7 Council Directive Article 4 90/394/EEC Reduction and replacement 1. The employer shall reduce the use of a carcinogen at the place of work, Carcinogens in particular by replacing it, in so far as is technically possible, by a substance, preparation or process which, under its conditions of use, is not dangerous or is less dangerous to workers' health or safety, as the case may be. 2. The employer shall, upon request, submit the findings of his investigations to the relevant authorities. Article 5
Even forest fires can contribute to the creation of small amounts of dioxins and furans. Dioxins and furans have been found in the air, soil, and food. Dioxins and furans are mainly distributed through the air. However, only a small percentage of exposure is from air. Eating contaminated food is the primary source of exposure. Impact on Human Dioxins have been characterized as likely to be human carcinogens and are anticipated to increase the risk of cancer at background levels of exposure. At body burden levels 10 times or less above those attributed to average background exposure, adverse noncancer health effects have been observed both in animals and, to a more limited extent, in humans. In animals these effects include changes in hormone systems, alterations in fetal development, reduced reproductive capacity, and immunosuppression. Effects specifically
These symptoms are relieved by the next cigarette. Most smokers need to smoke regularly to feel normal and to prevent nicotine withdrawal symptoms. So once you start smoking it is very hard to quit. But why is smoking so harmful? Cigarettes have tar in them which contains many chemicals. These deposit in the lungs and can get into the blood vessels and are carried to other parts of the body. Cigarette smoke contains over 4,000 chemicals, including over 50 known carcinogens (causes of cancer) and other poisons. In addition to different kinds of cancer (mouth, nose, throat, larynx, gullet, pancreas, bladder, cervix, blood, and kidney) it also may cause heart diseases, rheumatoid arthritis, fasten your ageing and have impact on your fertility. There are also other conditions where smoking often causes worse symptoms. For example: asthma, flu, chest infections, tuberculosis, chronic rhinitis, diabetic retinopathy, hyperthyroidism, multiple sclerosis, optic
IARC's overall evaluation is that formaldehyde is probably carcinogenic to humans (Group 2A). Later IARC classified formaldehyde as human carcinogen. Evaluating Pesticides for Carcinogenic Agency classified formaldehyde in Group B1 - probable human carcinogen, under conditions of unusually high or prolonged exposure. The National Toxicology Program, an interagency program of the Department of Health and Human Services, named formaldehyde as a known human carcinogen in its 12th Report on Carcinogens (2011). Toxicity for Reproduction Studies in Humans No increased risk of spontaneous abortion was seen after maternal or paternal exposure to formaldehyde based upon survey questionnaire. In one study of cosmetologists who used formaldehyde based disinfectant products as well as other chemicals a slight excess of spontaneous abortions is reported, but that finding could not be linked to any chemical exposure. Formaldehyde exposure levels were not reported in these studies
