Abstract
Particulate measuring below 2.5 microns have a very large effect on the body and the atmospheric environment, and are harmful to the respiratory organs and can cause asthma and lung disorders. The objective of this study was to identify the risk of PM2.5 exposure to communities in residential areas around nickel mining in Wolo District, Kolaka Regency. This study uses a descriptive observational method with a total sample of 324 respondents. The results showed that the highest value of the PM2.5 concentration measurement was 68.8 g/Nm3. The measurement of PM2.5 concentration has normally distributed so that the mean value is used as the PM2.5 concentration value. The risk of health living in the vicinity of the PT. Ceria Nugraha Indotama due to PM2.5 exposure of 0.093 mg/kg/day for 5 years (RQ<1) and 3.59 mg/kg/day for 30 years (RQ>1). It is necessary to plant green trees around the mining area to reduce the concentration of particulates in the air and to control the distance of the population to at least 2 km from the industrial center.

Summary
Indonesia selama 20 tahun terakhir, seiring penambahan angka industri yang menimbulkan pencemaran yang dihasilkan dari proses produksi industri seperti kontaminasi pencemaran air, udara, tanah dan pembuangan limbah Bahan Berbahaya dan Beracun (B3).[1]. Particulate Matter atau partikel debu adalah satu sumber pencemaran yang terdiri dari senyawa organik dan anorganik seperti Sulfat, Nitrat, Amonia, Sodium Klorida, Karbon, debu mineral dan air. Hal tersebut disebabkan oleh PM2,5 dapat dengan mudahnya masuk ke dalam saluran pernapasan dan alveoli. Penyakit Infeksi Saluran Pernapasan Atas umumnya terjadi akibat manifestasi cemaran yang terhirup oleh paru-paru dan terjadi secara terus menerus atau berlangsung secara berulang kali.[3] Particulate matter kurang dari 2.5 μm (PM2,5) mempunyai efek yang sangat besar bagi tubuh dan lingkungan atmosfer. Paparan PM2,5 berbahaya bagi organ pernapasan serta dapat menyebabkan asma dan gangguan paru-paru.[4]. Berdasarkan risiko kesehatan yang dapat terjadi maka studi ini bertujuan untuk mengidentifikasi intake paparan partikulat di sekitar wilayah pertambangan nikel berdasarkan karakteristik masyarakat dan partikulat yang dilihat dari lama tinggal, konsentrasi partikulat, laju inhalasi, lama pajanan, frekuensi pajanan dan berat badan
