Introduction

Calidad di Aire y e impacto riba Salubridad https://www.who.int/air-pollution/news-and-events/how-air-pollution-is-destroying-our-health

Nos ta papiando over di calidad di aire y salubridad awe, ya cu esaki a wordo treci dor di World Health Organization como un di e 5 factornan mas imporante den malesa no transmissible (manera diabeties, atake di curason, asthma etc.)

-90% di e population mundial ta biba cu calidad di aire in adecua -7 million di hende ta muri tur aña relationa cu calidad di aire -E ta affecta cantidad di hende cu ta haña asthma y otro problema tanto cardiaco, respiratorio y cognitivo. -World Health Organization ta calcula cu den ⅓ di e morto di stroke, cancer di pulmon y problema di curazon, calidad di aire tabata un factor importante cu a contribui.

Calidad di aire no ta semper visible of algo cu bo por hole Di un banda tin e huma of fijn stoff visible cu ta affecta nos salubridad Pero di otro banda tin piesanan mas chiquita unda 60 piesa tin e hanchura di un cabey y esaki por drenta deep den bo longen

E ta dificil pa haci algo over di e problema aki si nos no ta midi ki nos calidad di aire ta. Metabolic Foundation cu apoyo di UNESCO y cu appoyo di Futura Lab a bin cu un programa pa midi calidad de aire na 5 differente punto di Aruba y cu esaki cuminsa un conversation unda nos bin cu campaña pa mehora e calidad di aire y midi e progresso. E punto nan lo wordo annuncia mas laat, lo ta punto cu ta midi areanan cu nos ta expect pa tin hopi pollution, algun cu nos ta expect pa tin aire limpi pero primordialmente unda ta affecta hende.

Algun di e actividad nan cu ta contribui na mal calidad di aire Trafico y exhaust di auto Exhaust di deschecho/sushi (Dump / EcoGas) Exhaust industrial (WEB/ Refinaderia Etc.) Rosamento di tereno y construction Kimamento BBQ

Algun actividad cu ta yuda mehora calidad di aire Production di energia limpi Maneho di dump/residuo Core menos auto y filter e exhaust di auto Planta mata, mata ta haci aire limpi Disminui uso di energia cu ta disminui e cantidad di heavy fuel oil cu mester wordo usa Disminui uso di airco

Na Aruba nos no tin data pero nos por wak cu otro islanan den caribe cu economia similar ta afecta seriamente bou di calidad di aire (trinidad & tobago (1090) barbados (1026), bahamas (546)) Aña di bida per 100.000 hende cu ta wordo perdi. (https://www.who.int/gho/phe/outdoor_air_pollution/burden/en/)

  • Hopi biaha nos ta pensa dora cu nos ta isla y tin hopi biento e saki no lo affecta nos pero locual nos ta wak ta cu islanan den Caribe tin mas problema cu calidad di aire cu e paisnan riba terra firma, algun rason por ta cu no tin sufficiente espacio pa por pone un WEB, Refinaderia of dump leu for di population dus hende ta biba hopi mas serca di e contamination.

Nos ta den communication y collaboration cu Dienst Volksgezondheid y Directie Natuur en Milieu pero e no ta na e momento aki un program governamental.

E data lo ta disponible pa final di a aña.

Kiko nos ta midi: PM 10 (stoff visible) y PM 2.5 (stof invisible)

Esaki ta un di e metanan di SDG (Sustainable Development Goals tambe poni mundialmente)
