“…Tanto el comportamiento del OD como del pH, están altamente relacionados con la actividad minera, dado que solo se da en las estaciones E2 y E3. Una de las principales consecuencias de los vertidos mineros, tratados o no, es una disminución del OD y el pH (Naveen Saviour, 2012;Xia et al, 2017;Yang et al, 2018). Esto conlleva a una modificación del ecosistema desde la cabecera del río (Ekka et al, 2020).…”

“…A Neptune Plus multiple-collector inductively coupled plasma mass spectrometer (Thermo Scientic, Bremen, Germany) was used for sulfur isotope ratio measurement. The signals of sulfur isotopes were acquired on the interferencefree plateau in medium-to-high mass resolution mode to eliminate the isobaric interferences from oxygen species (e.g., 16 O 2 + ). Standard-sample bracketing (SSB) method was applied to determine the sulfur isotopic composition of the recovered solution aer extraction procedures.…”

“…In recent years, multiple-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) has become increasingly popular in rapid and precise measurements of sulfur isotopic compositions in various sulfur-bearing materials, such as sulfate and sulde minerals, [1][2][3] seawater and marine pore water sulfate, [4][5][6][7] and rainwater and soil solution, 8 even including medical serum and plasma. 9 Comparing with the traditional technique of gas-source isotope ratio mass spectrometry (GS-IRMS), [10][11][12][13][14][15][16] MC-ICP-MS requires a lower quantity sulfur injection (5-40 nmol sulfur 4 ) and is free from oxygen isotope correction for the produced sulfur dioxide gas (up to 1-3& shi in d 34 S values 17 ). However, MC-ICP-MS has three potential shortages, i.e.…”

“…Some associated minerals in coal mines will undergo oxidation reactions after contact with water and oxygen, and dissolve SO 4 2− and a variety of metal ions to form acid mine drainage (AMD). AMD is characterized by extremely low pH value and elevated in SO 4 2− , Fe 2+ , Mn 2+ and other polluting ions [3]. The untreated AMD directly flows into surface water and groundwater, which will adversely impact water resources [4].…”
