SeeGreen 5 ft. W X 7 ft. L Green Polypropylene Astroturf vs Artificial Grass 5 ft. x 7.5 ft.: which is safer?

Where these two actually differ

• We flag VOC off-gassing from polyurethane or latex adhesive, Polypropylene UV degradation and microplastic shedding, Backing adhesive failure and fiber separation and Infill contamination (if rubber granules used) on the AstroTurf and not on the Red Shed.
• We flag Volatile organic compounds (VOCs) and off-gassing from plastic backing and adhesives, Plastic additive leaching (phthalates, antimony, stabilizers) into soil or water, Microplastic shedding from fiber face and backing wear and Moisture retention and mold/bacterial growth in backing layers on the Red Shed and not on the AstroTurf.
• The AstroTurf is Polypropylene (PP) astroturf where the Red Shed is Polypropylene or polyethylene backing with synthetic fiber face, likely DWR-treated, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the AstroTurf is the one to buy.
• We are less certain about the Red Shed grade, at 35% confidence against 72%, because it discloses less.
