Environmental disaster off the coast of Sri Lanka. For about a week a container ship traveling from India to Sri Lanka, has been engulfed in flames and is now in danger of breaking up with very serious consequences for the environment.
The tiny plastic particles that hit shore pose a significant threat to the environment as they will remain in the water and along the coasts for a significant period. Eight containers have already ended up in the sea since the day of the explosion.
One of the conteiners is stranded on a beach very popular with tourists. If the boat were to break down, more than 300 tons of fuels and fuels would spill into the Indian Ocean, causing an unprecedented environmental disaster.
The ship is therefore currently closely monitored to prevent new explosions and subsequent oil spills
On the ship, which carries over twenty tons of nitric acid, there was a strong explosion already several days ago, as a result of which a fire broke out.
Attempts to put out the flames did not produce results for over a week and the transport of the vehicle out of the water was impossible. The Authority for the Protection of the Marine Environment (MEPA) stated that there is a possibility of acid rain due to the toxic fumes caused by the fire.
What problems can air quality cause us?
Air quality is a measure of how free of air pollution and how harmless the air is when breathed by humans. The study A chronology of global air quality study, published on the Philosophical transactions.
Series A, Mathematical, physical, and engineering sciences, is a very current and interesting insight into the chronology of global air quality and what can be derived from it for health. In the abstract we can read: "Air pollution has been recognized as a threat to human health since the time of Hippocrates, ca 400 BC.
Successive written accounts of air pollution occur in different countries through the following two millennia until measurements, from the eighteenth century onwards, show the growing scale of poor air quality in urban centers and close to industry, and the chemical characteristics of the gases and particulate matter.
The industrial revolution accelerated both the magnitude of emissions of the primary pollutants and the geographical spread of contributing countries as highly polluted cities became the defining issue, culminating with the great smog of London in 1952.
Europe and North America dominated emissions and suffered the majority of adverse effects until the latter decades of the twentieth century, by which time the transboundary issues of acid rain, forest decline and ground-level ozone became the main environmental and political air quality issues.
As controls on emissions of sulfur and nitrogen oxides (SO2 and NOx) began to take effect in Europe and North America, emissions in East and South Asia grew strongly and dominated global emissions by the early years of the twenty-first century.
The effects of air quality on human health had also returned to the top of the priorities by 2000 as new epidemiological evidence emerged. By this time, extensive networks of surface measurements and satellite remote sensing provided global measurements of both primary and secondary pollutants.
Global emissions of SO2 and NOx peaked, respectively, in ca 1990 and 2018 and have since declined to 2020 as a result of widespread emission controls. By contrast, with a lack of actions to abate ammonia, global emissions have continued to grow. This article is part of a discussion meeting issue 'Air quality, past present and future'"
