A change in the transportation needs today, a better future for tomorrow – climate change review

No sooner than later, the world will be living hell as a result of the transportation effects on our climate now escalating. The pressure is now growing towards their resultant effects to be totally eradicated in order to save our planet otherwise, the stabilisation of these effects; global warming, greenhouse gas (GHG) emission and degradation will need to be sought after. The world all over is at it now in an effort to restore our climate, to save it from the effects of these catastrophes/disasters. On the proposition of the Kyoto Protocol in1997, the main focus was to decrease greenhouse emissions of mainly six gases – Carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, Hydro fluorocarbons (HFCs) and Per fluorinated Compounds (PFCs). And transport alone, accounts for over 26% of global CO2 and has been regarded as one of the few industrial sectors wherein emissions are still on the increase, on this basis, researchers and policy makers are all at it to tackle the menace of climate changes through provision of sustainable transport. This paper focuses on the new and developed technologies like the renewable energy source [RES], which will be an alternative to transport fuels to avoid the dependence on petroleum which after effects are damaging to the world climate, and may probably not be there forever to continue serving the world ever increasing population. While the long term solutions are being sought, these alternatives will make do for now

Zinc and Selenium levels in Motor Mechanics, Paints Sprayers, Smokers, Lubricant Workers and Battery Workers Exposed to Lead in Nnewi, South Eastern Nigeria.

Objectives: This work was designed to determine zinc and Selenium levels in Motor Mechanics, Paints Sprayers, Smokers, Lubricant Workersand BatteryWorkers exposed to lead in Nnewi, South Eastern Nigeria.Subjects and methods: 100 exposed subjects were used for the study. The subjects were aged 25-30 years. The control subjects consisted of100 apparently healthy non-exposed age-matched individuals. The participants were educated on the benefits of the study and their informedconsent obtained before commencement of the study. Blood lead, zinc and selenium levels were determined in both exposed and controlsubjects.Results: The result shows that there was a significant increase in the blood lead level in the exposed subjects (23.00ƒÝg/dL„b1.77), whencompared with controls lead levels (10.68ƒÝg/dL „b29, P< 0.05),a significant decrease in zinc levels ( 104.73ƒÝg/dL „b1.9 ),when compared with controls zinc levels(130.68ƒÝg/dL „b1.24, P< 0.05) and a significant decrease in selenium levels( 60.99ƒÝg/dL „b1.01) when compared with thecontrols selenium levels (99.13ƒÝg/dL „b1.09 P< 0.05).Conclusion: These findings stated above appear to suggest that the occupationally exposed subjects have reduced serum zinc and selenium,with increase blood lead
