The Air Quality Surveillance System of the central zone of Cesar is constituted by 14 particulate matter monitoring stations (PM10 and PM2.5), distributed among the populations located in the area of incidence of coal mining projects. Its operation has allowed the environmental authorities to monitor atmospheric pollution and exert control over mining projects and other emission sources that affect these populations, achieving important results. In its strengthening process, in 2012 a technical committee was formed with the participation of various actors involved in environmental issues, which today is configured as a space for dialogue and concentration, which plans and coordinates the implementation of air decontamination actions, achieving effective and sustainable solutions over time, seeking to improve environmental quality in the municipalities of the mining area of Cesar

We conducted a cohort study to investigate the association between exposure to three different levels of outdoor air pollution and incidence of respiratory symptoms in a population with chronic cardiovascular and respiratory disease. We accompanied 756 participants for a period of six months through the maintenance of a daily record of symptoms and clinic visits. The symptoms with highest incidence rates were sneezing and hacking cough. Multivariate analysis showed that incidence of total symptoms was 60% and 74% lower in areas with medium and low levels of pollution compared to areas with high levels of pollution. These results suggest that negative respiratory effects occur at concentrations of particulate matter PM10 > 60ug/m³. Se realizó un estudio de cohorte para investigar si la exposición a tres niveles diferentes de contaminación atmosférica extra-domiciliaria está asociada a la incidencia de síntomas respiratorios en una población con enfermedad cardiovascular o respiratoria crónica. Se siguieron por un periodo de seis meses a 756 participantes con morbilidad, usando calendario diario de síntomas y visitas personales. Los síntomas que tuvieron mayores tasas de incidencia fueron el estornudo y la tos seca. El análisis multivariado mostró que la zona de mayor contaminación estaba asociada con un 60% y 74% más de síntomas respiratorios, comparada con la zona de contaminación media y baja, respectivamente. Estos resultados sugieren que los efectos negativos a nivel respiratorios son vistos con exposiciones por encima de 60µg/m³ de material particulado PM10 en esta población.

El objetivo del estudio fue determinar la asociación entre contaminación atmosférica y el desarrollo de síntomas respiratorios en preescolares de Bucaramanga, Colombia. Se realizó un estudio de cohorte durante un año, registrando síntomas en preescolares residentes en dos zonas de la ciudad con mediciones extremas de PM10 y se ajustó por variables individuales y residenciales con un modelo multinivel. Se siguieron 707 preescolares. El estornudo y la tos con flemas fueron los síntomas más frecuentes con tasas de incidencia de 277,2 y 203,3 eventos por 100 niños-mes en riesgo. En la zona de mayor contaminación, un incremento de 10µg/m³ en la concentración atmosférica de PM10 incrementó en 1,3 el número de síntomas diarios reportados. El análisis multinivel mostró ausencia de asociación entre PM10 y síntomas respiratorios y que la historia de asma, la exposición a alto flujo vehicular frente a la vivienda, la presencia de animales domésticos y de suelos de tierra, son las variables que tienen mayor efecto sobre la presencia de síntomas en esta población de preescolares. The aim of this study was to evaluate the association between air pollution and respiratory symptoms in preschoolers from Bucaramanga, Colombia. A cohort study was conducted by reporting daily symptoms in preschoolers living in two zones of the city with different PM10 air pollution levels. Individual and neighborhood variables were included in a multilevel analysis. In 707 preschoolers followed for a year, sneezing and cough with mucus were the most frequent symptoms, with incidence rates of 277.2 and 203.3 events per 100 child months at risk. In the high pollution zone, an increase of 10µg/m3 in PM10 concentration increased the reporting of daily symptoms by 1.3. Multilevel analysis showed no statistical association between PM10 and respiratory symptoms, but asthma history, heavy traffic in front of the residence, presence of domestic pets, and dirt floors were associated with respiratory symptoms.
