Reproductive toxicity of 1-bromopropane, a newly introduced alternative to ozone layer depleting solvents, in male rats.
1-Bromopropane has been newly introduced as an alternative to ozone-depleting solvents. We aimed to clarify its dose-dependent reproductive toxicity in male rats. Thirty-six Wistar male rats were randomly divided into 4 groups of 9. The groups were exposed to 200, 400, or 800 ppm 1-bromopropane or only fresh air, 8 h per day for 12 weeks. Epididymal sperm indices were evaluated after a 12-week ...
متن کاملA case of severe neurotoxicity associated with exposure to 1-bromopropane, an alternative to ozone-depleting or global-warming solvents.
Health hazard alerts to 1-bromopropane, an alternative to ozone layer-damaging organic solvents, have been issued by some countries. Herein, we report a new case of 1-bromopropane-induced neurotoxicity. A 43-year-old male industrial worker developed muscle weakness, pain, numbness, and gait disturbance. Neurological examination indicated sensory ataxic neuropathy associated with mild impairment...
متن کاملOzone-Depleting Substances: Alternatives
Surrounding the earth at a height of about 25 kilometers is the stratosphere, rich in ozone, which prevents the sun’s harmful ultraviolet (UV-B) rays from reaching the earth. UV-B rays have an adverse effect on all living organisms, including marine life, crops, animals and birds, and humans. In humans, UV-B is known to affect the immune system; to cause skin cancer, eye damage, and cataracts; ...

15 صفحه اولEmissions of Substitutes for Ozone-depleting Substances
Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), and Sulphur hexafluoride (SF6) are emitted from a number of end use sectors in which they substitute for ozone-depleting substances. These include refrigeration, air conditioning, aerosol applications, fire suppression, foam blowing, sterilants, and solvents. Emissions of these gases may occur within a year of sale or gradually over several ye...
