The eastern Chinese province of Shandong issued it's top level warning yesterday in relation to a toxic smog event.

It is believed that it is the first time than entire province has received a red-alert warning, as Shandong is the home to 96 million people.

The warning comes on the back of the fourth wave of toxic smog in recent weeks, following the country's capital Beijing issuing a red-alert at the start of the month, which was subsequently called earlier this week.

China's President Xi Jinping has said that the country's CO2 emissions will peak around the year 2030.

Coaling pollution is stated to be the primary source of the emissions, with China's state council planning to reduce 60% of major pollutants from coal-based fires by the year 2020.

However, environmental organisation Greenpeace revealed that the government recently gave the green light to over 150 new coal-burning plants in the country.

The World Health Organisation states that the maximum recommended exposure to harmful toxin PM2.5 is 25 micrograms per cubic metre over a 24 hour period.

Currently, in central Henan Province's Xinxiang, one of the cities currently under Shandong's red alert, are as high as 727 micrograms per cubic metre.
