In expressing units, mg/mL should be used instead of mg.ml-1, and mg/kg and μg/kg can be preferred alongside ppm and ppb, respectively. Statistical analysis results should be included in the discussion, and probability should be indicated with a capitalized and italicized "P" with no space after P (e.g., P<0.05). Special characters in the text should be created using the symbol and equation tab.
