As mobilization by 2-fold

Hello,
What does the red part mean in the text below? I can't figure out the meaning of mobilization here. (from a thesis on High arsenic (As) concentrations in the shallow ground waters of southern Louisiana).

These results are consistent with the addition of acetate and AQDS acting to facilitate increase in microbial respiration and hence, As mobilization by 2-fold (e.g., 197 g/L) in the acetate amended experiments and 4-fold (i.e., 380 g/L) in the experiments amended with both acetate and AQDS at the end of the experiments (Table 3).

    Rather poorly written, indeed!
    The previous text (somewhere) will describe what is defined as (and measured as) “arsenic mobilization”. It seems the result of such measurements produces values of grams/litre (g/L).

    In the experiments they added either acetate or acetate+AQDS at the beginning of the experiment and measured “As mobilization” at the end: the control yielded ~ 100 g/L; when acetate was added, they measured 197 g/L (and increase of ~twofold) and with acetate+AQDS they measured 380 g/L (and increase of ~4-fold).

    Is the person who wrote this a native English speaker?
    No.

    Now it's much easier to understand. Thanks.
