RAIL DISTURBANCE ON SOIL AND AIR

Hello folks!I hope  things are going well ,today i want to fulfill my promise.My topic is still under rail disturbance.My research is on how rail disturbance affect soil and air as  there under main rail disturbance as we saw on my previous research.

                SOIL POLLUTION


The increase of human population and vehicles ,emissions coming from transportation have become one of the most important sources of heavy metals ,PAHs and herbicides in the soil.

Fuel kindling ,vehicular and track material contusion,and leaked cargo effuse particles containing  metals that are deposited in the soils where they can remain for many years due to their low biodegradability.

These emissions are neither biologically nor chemically degraded,they can affect the growth of plants .Infact  plants and soil organisms are the first legatee of the emission pollutants.High engrossment levels of heavy metals are often found in the vicinity.

              AIR POLLUTION


Rail has continues to be an important mode of transportation .Though they have many positive impact,they have serious negative effects on environment especially air.This is because they produce nitrogen dioxide ,carbon dioxide and particulate matter that  can contribute to air pollution leading to negative  health effects.

This harmful gases results from smoke sent by trains into the air.Even the electric trains use large amount of coal that is burnt.This gases may even cause the  destruction of the ozone layer.As we all know how the ozone play an important role to reduce the heat from reaching the earth surface in large amount,as it can be very dangerous.

Hey Ashilline,

Awesome research round on the air and soil pollution created by the rail disturbance! As a reader who is unfamiliar with the topic, your facts are very clear to follow which creates a better understanding for myself. Like most modes of transportation, railways are a common factor in global warming due to their dispersion of carbon dioxide into the fresh air. However, it's impact may be larger due to the fact that trains travel for a long period of time and move at a slower pace than it's counterpart planes. In your previous post, you mentioned the rail disturbance in terms of noise and I believe this is a great point especially within the suburban cities. A couple blocks away from my house, their is a set of tracks that trains pass through on a daily basis and the sound of it's movements can be heard a mile away. I can't imagine living in the houses that are border lined along the tracks due to the noise level and I'm glad you are going to be looking into it for your next round of research. Here are some links to support my opinion on railway noise levels.

Hello Ashilline, 

Great research round. I really enjoyed reading about the air and soil pollution caused by rail disturbance. You went into depth, and the underlined titles made your categories clearer. Good job on putting your links underneath your post!  

I find that not many are conscious about the effects of soil pollution in general. The reality is that people think that emissions (from trains and cars alike) only effects the quality of air. However, as you mentioned, they also cause an increase of heavy metals, PAHs and herbicides in the soil! I really enjoyed how you touched on biodegradability. If you are interested, I suggest you elaborate more on that topic! I find it fascinating because, evidently, biodegradable products have many environmental and efficiency advantages. You could explain its relation on transport and pollution in general. Even so, I was curious on how people are combatting these effects of soil + air pollution. For example, possible ways could be raising awareness, etc.
