520			\|a Abstract This paper evaluates the impact of gold mining activity on surface water quality in the locality of Batouri (East, Cameroon). Water samples were collected from five separate points. These water samples were characterized from a physicochemical point of view. This characterization consisted to determine the hydrogen potential, the alkalinity, the electrical conductivity, the total dissolved solids, the dissolved oxygen, the chemical oxygen demand, the suspended solids and the turbidity as physical properties. Major ions and heavy metals (copper, zinc, nickel, iron, chromium, selenium, lead, arsenic, mercury and cadmium) were also determined using hydrochemical methods. The waters of the gold mining zone were acidic to slightly basic (5.1–8.1), weakly conductive (28.2–40 µm $ cm^{−1} $), turbid (29–721 NTU) and polluted by suspended solids (210–3410 mg $ L^{−1} $). Chemical oxygen demand values were higher than the World Health Organization standards with high dissolved oxygen levels. The results of heavy metals analysis indicated that nickel, iron, chromium, selenium, lead, arsenic, mercury and cadmium exceeded the limits recommended by the World Health Organization. The heavy metal pollution index, the water quality index, the sodium adsorption rate and the percentage of sodium were calculated for each sample in order to assess the overall water quality. The results of the hydrochemical evaluation showed that these waters were chlorinated calcium and calcium sulfate and not suitable for human consumption.

Water samples were collected from five separate points. These water samples were characterized from a physicochemical point of view. This characterization consisted to determine the hydrogen potential, the alkalinity, the electrical conductivity, the total dissolved solids, the dissolved oxygen, the chemical oxygen demand, the suspended solids and the turbidity as physical properties. Major ions and heavy metals (copper, zinc, nickel, iron, chromium, selenium, lead, arsenic, mercury and cadmium) were also determined using hydrochemical methods. The waters of the gold mining zone were acidic to slightly basic (5.1–8.1), weakly conductive (28.2–40 µm $ cm^{−1} $), turbid (29–721 NTU) and polluted by suspended solids (210–3410 mg $ L^{−1} $). Chemical oxygen demand values were higher than the World Health Organization standards with high dissolved oxygen levels. The results of heavy metals analysis indicated that nickel, iron, chromium, selenium, lead, arsenic, mercury and cadmium exceeded the limits recommended by the World Health Organization. The heavy metal pollution index, the water quality index, the sodium adsorption rate and the percentage of sodium were calculated for each sample in order to assess the overall water quality. The results of the hydrochemical evaluation showed that these waters were chlorinated calcium and calcium sulfate and not suitable for human consumption.

Water samples were collected from five separate points. These water samples were characterized from a physicochemical point of view. This characterization consisted to determine the hydrogen potential, the alkalinity, the electrical conductivity, the total dissolved solids, the dissolved oxygen, the chemical oxygen demand, the suspended solids and the turbidity as physical properties. Major ions and heavy metals (copper, zinc, nickel, iron, chromium, selenium, lead, arsenic, mercury and cadmium) were also determined using hydrochemical methods. The waters of the gold mining zone were acidic to slightly basic (5.1–8.1), weakly conductive (28.2–40 µm $ cm^{−1} $), turbid (29–721 NTU) and polluted by suspended solids (210–3410 mg $ L^{−1} $). Chemical oxygen demand values were higher than the World Health Organization standards with high dissolved oxygen levels. The results of heavy metals analysis indicated that nickel, iron, chromium, selenium, lead, arsenic, mercury and cadmium exceeded the limits recommended by the World Health Organization. The heavy metal pollution index, the water quality index, the sodium adsorption rate and the percentage of sodium were calculated for each sample in order to assess the overall water quality. The results of the hydrochemical evaluation showed that these waters were chlorinated calcium and calcium sulfate and not suitable for human consumption.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Semi-mechanized gold mining</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Surface water</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sediments</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Physicochemical properties</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Heavy metals</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pollution</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Takougang Kingni, S.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ayiwouo Ngounouno, M.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ndi, A.

title_auth	The impact of gold mining exploitation on the physicochemical quality of water: case of Batouri (Cameroon)
abstract	Abstract This paper evaluates the impact of gold mining activity on surface water quality in the locality of Batouri (East, Cameroon). Water samples were collected from five separate points. These water samples were characterized from a physicochemical point of view. This characterization consisted to determine the hydrogen potential, the alkalinity, the electrical conductivity, the total dissolved solids, the dissolved oxygen, the chemical oxygen demand, the suspended solids and the turbidity as physical properties. Major ions and heavy metals (copper, zinc, nickel, iron, chromium, selenium, lead, arsenic, mercury and cadmium) were also determined using hydrochemical methods. The waters of the gold mining zone were acidic to slightly basic (5.1–8.1), weakly conductive (28.2–40 µm $ cm^{−1} $), turbid (29–721 NTU) and polluted by suspended solids (210–3410 mg $ L^{−1} $). Chemical oxygen demand values were higher than the World Health Organization standards with high dissolved oxygen levels. The results of heavy metals analysis indicated that nickel, iron, chromium, selenium, lead, arsenic, mercury and cadmium exceeded the limits recommended by the World Health Organization. The heavy metal pollution index, the water quality index, the sodium adsorption rate and the percentage of sodium were calculated for each sample in order to assess the overall water quality. The results of the hydrochemical evaluation showed that these waters were chlorinated calcium and calcium sulfate and not suitable for human consumption.
