Analysis of PM trends in open-pit mining: Assessing emission controls and WHO guideline compliance.

This study evaluated the concentrations, trends, and variability of PM particulate matter in two Air Quality Monitoring Systems (CorpoGuajira's_AQMS and Cerrejón's_AQMS) in an open-pit coal mine in northeastern Colombia from 2010 to 2020. Additionally, different levels of emission controls were evaluated to achieve compliance with Colombian standards and international WHO guidelines. The results showed concentrations ranging from 24.

Characterization of water-soluble ions in PM over an industrial area in northern Colombia: Temporal variations and correlation with satellite data.

This study was designed to assess the concentrations of nine water-soluble ions in PM mass at two sites of an open-pit coal mine and to analyze the correlation and variation of the spatial distribution of sulfate ions with the PM sulfate aerosol optical depth at 550 nm (suaod550) in two (North and South) stations of the study area. The daily average of PM concentrations ranged from 20.48 to 53.

Human health risk assessment of PM-bound heavy metals and PAHs around the Latin America's Largest opencast coal mine.

Air pollution in opencast coal mine areas is a critical issue, resulting in harmful severe effects on human health. Therefore, it is essential to understand the air pollution factors and to assess the risks to humans. This study evaluated the potential risks (carcinogen and non-carcinogen) of inhalation exposure to PM-bound heavy metals and Polycyclic Aromatic Hydrocarbons (PAHs) in an open pit mine in northern Colombia.

Health risk assessment for particulate matter: application of AirQ+ model in the northern Caribbean region of Colombia.

Unlabelled: Air pollution is considered the world's most important environmental and public health risk. The annual exposure for particulate matter (PM) in the northern Caribbean region of Colombia between 2011 and 2019 was determined using PM records from 25 monitoring stations located within the area. The impact of exposure to particulate matter was assessed through the updated Global Burden of Disease health risk functions using the AirQ+ model for mortality attributable to acute lower respiratory disease (in children ≤ 4 years); mortality in adults aged > 18 years old attributable to chronic obstructive pulmonary disease, ischaemic heart disease, lung cancer, and stroke; and all-cause post-neonatal infant mortality.

Meteorological factors contributing to organic and elemental carbon concentrations in PM near an open-pit coal mine.

Variations in the carbonaceous aerosol contents, organic carbon (OC) and elemental carbon (EC), in particulate matter less than 10 μm in size (PM), were analyzed at sites influenced by coal mining in an open-pit mine located in northern Colombia. Samples were collected during different seasonal periods throughout 2015. Meteorological variables for each site were examined during the different seasons.

Impact of lockdown on particulate matter concentrations in Colombia during the COVID-19 pandemic.

The first confirmed case of COVID-19 in Colombia was reported on March 6, 2020. For this reason, on March 25, preventive isolation was declared mandatory. These measures involved the suspension of economic activities and drastically reduced the number of vehicles on the road.

Intake Fraction of PM from Coal Mine Emissions in the North of Colombia.

Intake fraction was determined in this study to provide insight into population exposures to PM that is effectively inhaled due to emissions of an opencast coal mine. We applied the CALPUFF model to a coal mine in Northern Colombia, which has 6 active pits with an annual production of 33.7 million tons.
