Sebagai negara tropis pelapukan tanah di Indonesia berlangsung intensif. Penentuan daerah prospek mineralisasi pada penelitian ini menggunakan metode geokimia tanah, dengan melakukan pengambilan sampel dari tanah lapukan tersebut. Daerah Nanga Bangik, Desa Jemah, Kecamatan Boyan Tanjung, Kabupaten Kapuas Hulu, Provinsi Kalimantan Barat memiliki kondisi geologi yang sangat memungkinkan terbentuk mineralisasi logam. Penyelidikan ini dilakukan untuk menentukan daerah prospek mineralisasi. Sebanyak 135 sampel tanah telah diambil menggunakan sistem ridge and spurs dari horizon B dengan jarak antar titik lokasi sampel 75 – 100 meter. Sampel tanah tersebut dianalisis di Laboratorium Pusat Sumber Daya Mineral Batubara dan Panas Bumi (PSDMBP). Analisis laboratorium menggunakan metode AAS (Atomic Absorption Spectroscopy), unsur yang dianalisis meliputi Cu, Pb, Zn, Fe, Mn, Ag dan Au. Metode analisis statistik yang dilakukan meliputi analisis distribusi, perhitungan nilai threshold dengan metode perhitungan Mean+2 SDEV dan Median+2 MAD dan korelasi antar unsur dengan Faktor Analisis. Berdasarkan perhitungan nilai threshold menggunakan dua metode statistik yang berbeda, didapatkan beberapa nilai anomali dan tiga faktor kelompok unsur: Faktor 1: Pb-Fe-Zn-Ag Faktor 2: Mn-Cu dan Faktor 3 berupa unsur Au yang diinterpretasikan berhubungan dengan adanya mineralisasi logam. Didapatkan tiga daerah prospek mineralisasi logam di Bukit Empajak, Bukit Pirang dan Bukit Limau.

The presence of some chemical compounds at higher levels than maximum permissible concentrations (MPC) in the drinking water, suggests of water resources pollution. In this paper the following elements were analyzed: total arsenic, cadmium, lead, cooper and zinc. Twelve samples of water from the water supply system from the city of Skopje were examined during one year from three different springs. Also, ten samples of bottled water from three producers from the Macedonian market were tested.The determined average mass concentrations of total As, Cd(II), Pb(II), Cu(II) and Zn(II) in the analyzed water samples from the water supply system are 1.35 μg/l, 0.06 μg/l, 0.6 μg/l, 0.9 μg/l and 1,12 μg/l, respectively, and for the tested bottled water, the mean values ranges from 0.56 - 0.83 μg total As / l, 0.053 - 0.056 μg Cd(II)/l, 0.51 - 0.54 μg Pb(II)/l , 0.6 - 0.87 μg Cu(II)/l and 0.68 - 0.8 μg Zn(II)/l water.The following instrumental analytical methods and techniques were used for the analysis of the tested samples of drinking water: flame atomic absorption spectroscopy (AAS), atomic absorption spectroscopy with hydride cеll, electrothermal atomic absorption spectroscopy.The obtained results are shown in tables and graphic form. According to the obtained results a comparative analysis was carried out indicate that it is a water of good quality that can be used in different branches of the process industry.The obtained results in this paper do not exceed the values of the MPC of the Republic of Macedonia prescribed by the legal regulations for the drinking water, which confirm the health safety of the drinking water from the water supply system in the city of Skopje and the packed waters from the Macedonian market in relation to the tested elements.
