With the improvements made to the IPE website and thus China Pollution Map Database, over the last two years the number of official government-sourced violation records, from all regions in China, added to the China Pollution Map Database, has grown by over 40,000, each having its own particular circumstances and need for a prompt and effective ...
The January 2024 version of the WHO database contains results of ambient (outdoor) air pollution monitoring from almost 5,390 towns and cities in 63 countries. Air quality in the database is represented by the annual mean concentration of particulate matter ( PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 micrometers, respectively).
Map of PM2.5 pollution over China from April to August 2014. Air pollution is a major public health issue in China. Over the past three decades, the rapid development of China has resulted in excessive emissions of greenhouse gases. Among the 337 cities, more than 40 percent of the major air pollutant concentrations exceeded Chinese standards. [29]
China reversed a five-year trend of declining levels of pollution, the report found. Chinese cities used to dominate global rankings of the world’s worst air quality but a raft of clean air ...
The World Bank estimates that 16 of the world's most-polluted cities are located in China. [40] Coastal pollution is widespread, leading to declines in habitat quality and increasing harmful algal blooms. [41] The largest algal bloom recorded in history occurred in China around the southern Yellow Sea in 2008, and was easily observed from space ...
The ranking takes into account healthcare, education, infrastructure, safety, and the threat of terrorism. It then gives an overall mark out of 100.
Below is a list of 526 cities sorted by their annual mean concentration of PM2.5 (μg/m 3) in 2022. [1] [2] By default the least polluted cities which have fewest particulates in the air come first. Click on the arrows next to the table's headers to have the most polluted cities ranked first. Please note that constraints exist in this type of ...
Wildlife in China share habitat with and bear acute pressure from the world's largest population of humans. At least 840 species are threatened, vulnerable or in danger of local extinction in China, due mainly to human activity such as habitat destruction, pollution and poaching for food, fur and ingredients for traditional Chinese medicine.
