china water pollution 2020

Algae bloom in Dianchi Lake, Kunming City, Yunnan Province, 2012. BEIJING, Jan. 14 (Xinhua) -- China's top environmental watchdog has reiterated its ambition to fight environmental pollution in 2020, as positive results have been reaped through efforts to clean up the environment in the past year. Yunnan Dianchi Lake was one of the most polluted lakes in China. The Environmental Quality Standards for Surface Water was introduced in 2002, in which China's surface water is classified into five grades from I to V, with Grade I defined as the best, while water at Grade V is for agriculture and general landscape usage, and water "inferior to Grade V" is called "unusable.". The study confirms the effectiveness of massive environmental protection efforts aimed at controlling pollution discharge and improving water quality in China over the past nearly two decades, notwithstanding growing pressure from human activity. However, Dianchi Lake was a major source of freshwater fish in Kunming City 30 years ago. Your feedback will go directly to Science X editors. Some water sources have not completely rectified their environmental problems…. Shen Sunan is Senior Researcher of Institute of Public and Environmental Affairs (IPE). Water is essential to life on Earth, however, water pollution is one of the biggest ecological crises we are facing today on a global scale. /VCG. A new study shows that China's inland surface water quality improved significantly from 2003-2017, coinciding with major efforts beginning in 2001 to reduce water pollution in the country. Surface water scores account for 50% of the total score; Drinking water scores account for 30%; and. Having dropped dramatically in the height of lockdown, the concentration of harmful gases seen recently surpasses levels during the same period last year, according to the Centre for Research on Energy and Clean Air (CREA). or, by Chinese Academy of Sciences. Regions with the best water quality are primarily concentrated in the Qinghai-Tibet Plateau and its surrounding areas, especially in the first and second steps in China’s elevation above sea-level. The researchers analyzed the nationwide variability of inland surface water quality across China during this 15-year period and the response to anthropogenic pollution. In general, northern regions showed relatively poor water quality due to intense human pressure on local environments. is_confirmation;var mt = parseInt(jQuery('html').css('margin-top'), 10) + parseInt(jQuery('body').css('margin-top'), 10) + 100;if(is_form){jQuery('#gform_wrapper_4').html(form_content.html());if(form_content.hasClass('gform_validation_error')){jQuery('#gform_wrapper_4').addClass('gform_validation_error');} else {jQuery('#gform_wrapper_4').removeClass('gform_validation_error');}setTimeout( function() { /* delay the scroll by 50 milliseconds to fix a bug in chrome */ jQuery(document).scrollTop(jQuery('#gform_wrapper_4').offset().top - mt); }, 50 );if(window['gformInitDatepicker']) {gformInitDatepicker();}if(window['gformInitPriceFields']) {gformInitPriceFields();}var current_page = jQuery('#gform_source_page_number_4').val();gformInitSpinner( 4, 'https://www.chinawaterrisk.org/wp-content/plugins/gravityforms/images/spinner.gif' );jQuery(document).trigger('gform_page_loaded', [4, current_page]);window['gf_submitting_4'] = false;}else if(!is_redirect){var confirmation_content = jQuery(this).contents().find('.GF_AJAX_POSTBACK').html();if(!confirmation_content){confirmation_content = contents;}setTimeout(function(){jQuery('#gform_wrapper_4').replaceWith(confirmation_content);jQuery(document).scrollTop(jQuery('#gf_4').offset().top - mt);jQuery(document).trigger('gform_confirmation_loaded', [4]);window['gf_submitting_4'] = false;}, 50);}else{jQuery('#gform_4').append(contents);if(window['gformRedirect']) {gformRedirect();}}jQuery(document).trigger('gform_post_render', [4, current_page]);} );} ); jQuery(document).bind('gform_post_render', function(event, formId, currentPage){if(formId == 4) {if(typeof Placeholders != 'undefined'){ In recent years, her work focuses on environmental big data applications and environment policy research. However, the original data may still be difficult for the public to understand due to its specialised nature. Starting from 2016, the water quality has seen a significant improvement. Although Chinese bureaucrats will, of course, claim otherwise, the World Health Organization (WHO) recently estimated that 75% of all disease in China comes from water pollution. Medical Xpress covers all medical research advances and health news, Tech Xplore covers the latest engineering, electronics and technology advances, Science X Network offers the most comprehensive sci-tech news coverage on the web. In 2019, therefore, IPE developed the Blue City Water Quality Index (BCWQI) and scored 337 municipal cities and 25 counties on their overall water quality in 2018. Three “red lines” were declared, with targets set for 2015, 2020, and 2030 that covered maximum total water use, efficiency of water use and pollution control. The analysis is based on 600,000 water quality data points gathered the same year. Restoring lake and river, implementing better sewage treatment systems, tackling urban and rural water disposal problems, as well as evaluating high-risk industries along water bodies are the four major tasks in the coming years. At the start of his second term in late 2017, President Xi Jinping identified water pollution as a priority to improve the environment in China by 2020. Below we go into more detail on the map and how the results were calculated. Due to the fact that existing groundwater data must be gathered from multiple sources with various record years, depths of monitoring points, and types of groundwater, this first edition of the BCWQI is far from complete.

The aggregate data illustrates changes in China’s environmental water quality. /VCG. You can unsubscribe at any time and we'll never share your details to third parties. Water quality to the south of the Yangtze River is better than water quality to the north of the Yangtze River. Going forward, eliminating "inferior than Grade V" water is still a long battle to fight. Beijing ICP prepared NO.16065310-3, Battle against pollution: The return of clear water, Battle against pollution – making blue skies stay. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no Half of China’s population cannot access water that is safe for human consumption and two-thirds of China’s rural population relies on tainted water. In 2018, the previous "inferior than Grade V" water quality reached IV and remained the same in 2019. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); The research was conducted by a team led by Profs.

Air pollution in China has risen above levels seen before the coronavirus pandemic for the first time. As the number of app users grows, more people are able to follow these trends. By scoring 337 municipal cities & 25 counties, the first Blue City Water Quality Map helps the public better understand different regions' water qualities & identify those in need of improvement, Qinghai, Tibet & Guizhou have the best overall water quality vs. Tianjin, Shanxi & Hebei have the worst; a deeper dive to reveals different patterns for surface water, drinking water & groundwater, The first edition of the map is far from complete; however, being the first to display groundwater quality for every city, it hopes to improve groundwater quality monitoring & disclosure platforms. }} } );jQuery(document).bind('gform_post_conditional_logic', function(event, formId, fields, isInit){} ); jQuery(document).ready(function(){jQuery(document).trigger('gform_post_render', [4, 1]) } ); © 2020 China Water Risk. Drinking water sources are comprehensively evaluated based on water quality classifications, transgressions of pollution standards and the progress of environmental rectifications. IPE takes it up another notch with the Blue City Water Quality Map. They also suggested that water quality dynamics and the forces propelling such dynamics should determine strategies used to control water pollution, while taking regional variations into account. The results formed the first Blue City Water Quality Map, now available on the Blue Map app, which helps the public better understand regions with good water quality and those in need of improvement across the country. A new study shows that China's inland surface water quality improved significantly from 2003-2017, coinciding with major efforts beginning in 2001 to reduce water pollution in the country.

Improved inland surface water quality across the country is mainly attributable to reduced pollution emissions in the industrial, rural, and urban residential sectors. Drinking water standards, wastewater treatment, and pollution control all received attention, in order to reduce water pollution by 30-50%. It has suffered from eutrophication since the early 2000s. The Institute of Public and Environmental Affairs (IPE) has collected water quality data issued by government departments across China since 2016, sorting and standardising the data that is then displayed on the Blue Map mobile app. Their findings were published in Science Advances. The city score is the average annual score of all the monitoring points in its jurisdiction. However, in many water areas across the country, eutrophication (enrichment of a water body with minerals and nutrients leading to the excessive growth of algae) became a difficult problem to solve. Yangquan City of Shanxi Province ranked the lowest, with a score of 41.92. 8000 water clean up projects were launched in early 2017, for an investment of 667.4 billion yuan (US$100.2 billion). Key points to note from the 2018 Blue City Water Quality Map above: According to the average BCWQI scores of provincial jurisdictions: Since the Action Plan for the Prevention and Control of Water Pollution was issued in 2015, China has implemented rigorous water pollution control and national surface water quality has improved each year. For surface water and groundwater quality assessments, each water quality classification, according to the Ministry of Ecology and Environment’s environmental quality standards (Class I – Class V), is given a quantitative value. is_redirect && ! Although the outcome saw some improvements in the ground water quality, the plans lacked thorough evaluation of the degrees of pollution in various water bodies while the targets were set too ahead. The action plan proposed that by 2020, above 70 percent (75 percent by 2030) of the water areas of the seven key basins will have at least Grade Ⅲ water quality standard; over 93 percent (95 percent by 2030) of the drinking water sources in prefecture-level cities will reach at least Grade Ⅲ. Placeholders.enable(); The researchers believe China's inland surface waters will achieve good ecological status in the near future if current trends hold.
