China's Ministry of Environmental Protection reported Monday that several local governments and companies have breached environmental protection measures within the country.
After a four-day inspection, 202 irregularities were found, such as the unauthorized restart of production despite a government ban or failure to comply with emission reducing measures, reported official news agency Xinhua.
The irregularities were discovered by 18 inspection teams sent to 16 cities, including Tianjin and Beijing, where a blue alert was issued on Saturday due to air pollution.
Inspection teams urged local governments and companies to investigate and rectify the situation as soon as possible.
In early March, the Chinese government presented a plan dedicated to improving air quality with a 3 percent reduction of emissions of the main pollutants sulfur dioxide and nitrogen oxide.
Reduced mining and consumption of coal, cutting down excess generation of electricity through coal and a decline in steel production were among the measures announced.
