Air quality in China has improved in 2018, according to a report released today by the Ministry of Ecology and Environment, which compiles the data collected in 338 cities in the country.
Among the areas covered by the study, 79.3% of the days registered "good" air quality, in an homologous increase of 1.3% wich falls within the target set by the Chinese Government.
In the area of Beijing and Tianjin counties and Hebei Province, one of the most polluted areas in the country, the percentage of days with good air quality stood at 50.5%, an increase of 1.2% in relation to the previous year.
The density of PM 2.5 particles - the finest and most susceptible of getting in the lungs - dropped 11.8% year on year to an average of 60 micrograms per cubic meter.
The maximum level of concentration recommended by the World Health Organization (WHO) is 25 micrograms per cubic meter.
The cities of Harbin and Changchun, capital cities of the provinces of Heilongjiang and Jilin, respectively, in the north-east of the country, were the ones that registered the greatest improvement in air quality in 2018 according to the report, which does not go into detail.
Last year, China announced a new action plan to reduce air pollution over the next three years.
The goal is to reduce emissions of sulfur dioxide and nitrogen oxides by more than 15% compared to 2015, and that around 300 of the cities covered can have 80% of days with good air quality levels.
