You might try enclosing the sheets in a plastic tote with a tight fitting lid and include an open dish or an odour absorbent material like activated charcoal, baking soda, tea tree oil, volcanic rock, or even unscented kitty litter. And keep checking the contents e very few days until odour is gone It may take a few days or weeks but will hasten the odour removal process. If you’re considering deacidification you need to ensure the paper and inks can withstand which ever solution (aqueous or non-aqueous) you plan to use. So that means rigourous spot testing first. If there’s a paper conservator near you perhaps they could help or have other ideas. AIC has an online directory of conservators I believe.
