![]() القطران يتركب من الاف المركبات والمعروف منها 50% فقط وهو غير امن للمرأه الحامل اطلاقاً لانه قدد يسبب طفرات جينيه ( هذا من كلام دكتور متخصص في الصيدله السريريه يدرسني حالياً ) او حتى لو كانت هناك نيه للحمل يجب التوقف عنه بفتره شهرين على الاقل قبل الحمل الطفرات من الممكن ان تحدث من امرأه لاخرى ممكن ان تحدث بنسبه 4/10 |

ارجوك اخوي عوام اريد المصدر واي مصدر ثاني يقول عن القطران امن او غير امن انا مومنه بانه امن واستعملته لابني وايماني من البحوث التي قرائها الاخ قيس العبيدي والحقيقه الرجل ارجع المصادر والكب والبحوث الى عمه الدكتور في امراض الدم وعمه مسافرالان ومنذ سنين الى ماليزيا للتدريس بالجامعات لذلك من الصعب ان ياتي لي باسماء الكتب والمراجع وقد تسال لماذا تريدين الاسماء فاجيب لاني تقريبا جمعت كل ماقيل هنا وكل تجاربنا في كتاب جميل عن القطران وجعلته اسئله واجوبه وفيه اكثر من 30 سوال وجواب واحد الاسئله هو هل القطران امن لذلك اريد همتك معي وممكن ترسل لي على الخاص اي اسم او مصدر لنتاكد منه حيث اناقش الاخ قيس ثم نطرحه على العام |

كيف يكون امن وهو لم يعرف تركيبه 100% ؟؟؟؟ CARCINOGENICITY Coal tars and coal tar pitches are known to be human carcinogens based on sufficient evidence of carcinogenicity in humans (IARC 1985, 1987). There have been a number of case reports of skin cancer in patients who used tar ointments for a variety of skin diseases. A mortality analysis in the United Kingdom from 1946 showed a greatly increased scrotal cancer risk for patent-fuel workers. Furthermore, a large number of case reports describe the development of skin (including the scrotum) cancer in workers exposed to coal tars or coal-tar pitches. Several epidemiological studies have shown an excess of lung cancer among workers exposed to coal tar fumes in coal gasification and coke production. A cohort study of U.S. roofers indicated an increased risk for cancer of the lung and suggested increased risks for cancers of the oral cavity, larynx, esophagus, stomach, skin, and bladder, and for leukemia. Some support for excess risks of lung, laryngeal, and oral cavity cancer is provided by other studies of roofers. Several epidemiological studies have shown excesses of lung and urinary bladder cancer among workers exposed to pitch fumes in aluminium production plants. A slight excess of lung cancer was found among furnace and maintenance workers exposed to coal tar pitch fumes in a calcium carbide production plant. One study showed a small excess of bladder cancer in tar distillers and in patent-fuel workers. An elevated risk of cancer of the renal pelvis was observed in workers exposed to "petroleum or tar or pitch". One study of millwrights and welders exposed to coal tars and coal tar pitch in a stamping plant showed significant excesses of leukemia and of cancers of the lung and digestive organs (IARC 1987). When administered topically to experimental animals, coal tars (CAS No.8007-45-2), coal tar extracts, and high-temperature coal tars induced skin papillomas and carcinomas .Pharmaceutical coal tars and tar ointments caused skin papillomas, squamous cell carcinomas, and/or carcinomas when applied to the skin of mice of both sexes. When applied to the skin, coal tar induced epidermoid lung carcinomas in rats, and when applied to the ears of rabbits, coal tar caused skin papillomas. When administered intramuscularly, coal tar fume condensate induced injection site sarcomas in mice of both sexes. Analyses of coal tars indicate the presence of a number of known carcinogens and potentially carcinogenic chemicals which are discussed elsewhere in this document, including benz [a ]anthracene,benzo [b ]fluoranthene,benzo [j] fluoranthene,benzo [k ]fluoranthene, benzo [a pyrene, dibenz [a,h ]anthracene, dibenzo [a,i ]pyrene, and indeno [1,2,3-cd ]pyrene (see Polycyclic Aromatic Hydrocarbons, 15 listings). When administered topically or by whole-body exposure, coal tar pitch, a coal tar distillate, induced skin papillomas and carcinomas in mice. When applied topically, coal tar pitch extracts induced skin papillomas and carcinomas in mice; these extracts also had both initiating and promoting activities (in separate studies) in mouse skin. In one study, an extract of a hard residue from a coke oven tar induced lung tumours, but no skin tumours, in mice. Analyses of coal tar pitches reveal the presence of several carcinogenic polycyclic aromatic hydrocarbons (IARC 1985).. KNOWN TO BE A HUMAN CARCINOGEN TENTH REPORT ON CARCINOGENS وهذا الرابط فيه موضوع اخر عن خطوره القطران http://toxnet.nlm.nih.gov/cgi-bin/si...rm+@DOCNO+5050 وكانت لدي كتب الكترورنيه نزلتها من موقع منظمه الصحه والغذاء الامريكيه جميعها تتحدث عن خطورته وكان خطأ مني اني حذتها لكن ان شاء الله اقرب فرصه ادور عليها واحملها مره اخرى |
