IS YOUR HEALTH AT RISK FROM COAL DUST?

Massive coal port expansion could be putting your health at risk

There is no such thing as a safe health threshold for coal dust.

This is confirmed by the World Health Organisation, which stated:

“There may be no safe threshold for fine particulate matter and the effects are linearly related to concentration.”

Yet just a few kilometres downwind of the port city of Mormugao, coal terminals, which already feature open coal stockpiles, are being proposed for massive expansion.

This puts the health of the people of Mormugao and surrounding townships and beach communities – particularly those living closer to the port and rail line, at risk.

What makes coal dust so dangerous?

Coal dust particulates (tiny pieces of coal) are of particular concern because they contain heavy metals which are toxic at low concentrations.

They include lead, mercury, nickel, tin, cadmium, mercury, antimony, and arsenic, as well as radio isotopes of thorium and strontium.

Coal dust, especially fine coal dust, has been identified by health professionals and doctors around the world as causing a range of diseases and health problems.

Examples include an increased incidence of heart and respiratory diseases like asthma and lung cancer.

Fine invisible coal dust particles less than 2.5 microns long lodge in the lungs and are not naturally expelled, so long-term exposure increases the risk of health problems.

More exposure increases risk

The health risks increase with the level and frequency of exposure.

As fine coal dust accumulates in the lungs over time duration of exposure is also a risk factor.

In fact, epidemiological research suggests that there is no threshold at which it is safe to breathe coal dust.

This conclusion is supported both by the World Health Organisation and several research studies.

The factors that may influence the health effects related to exposure to particles include:

The chemical composition and physical properties of the particlesthe mass concentration of the airborne particles

The size of the particles (smaller particles may be associated with more adverse effects because they can be inhaled more deeply into the lungs)

The duration of exposure (short and long term, possibly in years).

Coal dust could be three times worse around Mormugao

The  coal port around Mormugao, has  already put the health of the people of Mormugao region at risk.

What’s even worse is that fine coal dust and other particulate levels could increase up to three times current levels if a proposal for the coal terminals  within port land complex proceeds.

Not enough is being done to protect people’s health

To date there has been no research on the expected health impacts in the Mormugao region of coal dust from the rail and port operations at the Point.

Data to conduct such research, such as the geographic distribution of the very fine coal dust emissions (smaller than PM 2.5) and related health impacts from current coal exports, is not being collected.

Your health is not being protected

In fact, the standards that the Indian Government suggests for coal dust are much worse than the standards recommended by the World Health Organisation, and they are not monitored or enforced by government.

What action needs to be taken?

1. Very fine coal dust needs to be properly monitored

Currently, Total Suspended Particulates, (TSP) which includes coal dust from the coal terminal is monitored for the larger PM10 particulates, but it is not monitored for the extremely fine particulates that have the potential to do the most damage.

A new fine dust monitor that can measure the smaller PM 2.5 particulates should be planned for the Beach near the Point, one monitoring station isn’t enough. There needs to be a network of stations to check the air quality in different areas.

2. Monitoring must occur in Mormugao and the Beaches 

The lightness of fine dust particles allows them to remain suspended for long periods, and to blow hundreds to thousands of kilometres depending on wind and other meteorological conditions.

Prevailing winds blow from the sea already blow fine coal dust from the  port land coal terminals over a vast range .

Coal dust from the existing  port terminals within the port lands has been reported in the Harbour apartments and  the Beach,

As these particulates are visible they are likely to be PM10 so it seems both PM10 and PM2.5 and smaller particulates are reaching the region .

These need to be properly monitored and correlated with health assessments for the area over time.

3. Monitoring of coal dust needs to be continuous and publicly available

The community has a right to know about the dangers to them of coal dust in the air.

At the moment, no coal dust monitoring data  is available.

While you can get some idea for the month of the percentage and amount of each month’s fine dark particulates (probably the more hazardous coal and diesel particulates) from the monitoring sites, you still do not know daily, hourly, or minute levels of these emissions.

You do not get data that shows more dangerously high levels in “spikes” of emissions due to variability in wind and moisture conditions, and the degree of disturbance of the coal, because they are lost in the presentation of reported data as “averaged” daily and monthly values.

  1. Terrific article! This is the kind of information that are meant to be shared
    around the web. Shame on Google for no longer positioning this submit higher!

    Come on over and talk over with my site .

    Thank you =)

  2. Thank you for any other informative website. Where else may I get that kind of information written in such a perfect manner?
    I have a undertaking that I am just now working on, and I
    have been at the look out for such info.

  3. Hi there just wanted to give you a quick heads up and let you know
    a few of the pictures aren’t loading properly. I’m not sure why but I think its a linking issue.
    I’ve tried it in two different browsers and both show the same results.

  4. Thanks for the something totally new you have disclosed in your post. One thing I would really like to reply to is that FSBO interactions are built over time. By presenting yourself to the owners the first saturday their FSBO will be announced, ahead of the masses start calling on Monday, you develop a good interconnection. By sending them equipment, educational supplies, free accounts, and forms, you become a good ally. If you take a personal interest in them and their circumstance, you create a solid network that, many times, pays off once the owners opt with a real estate agent they know plus trust – preferably you actually.
