Purchased some bulk bacopa extract with .86 ppm of lead... safe?

Just received COA of some bacopa extract I purchased. Here is a link to a study evaluating the acceptable levels of heavy metals in dietary supplements. depending on whose standard you go by .86ppm of lead is either above or below. erring on the side of caution i am probably going to return the product. opinions. should i keep it and ingest or no?

edit: i have been taking a different brand of bacopa for a few months. and purchased this in bulk to save money, i havent started taking it yet because i still have some left in the original bottle. i dont have a coa for the brand i am currently taking, thus it could be more or less than the bulk bacopa i purchased.
edit 2: received the COA for gotu kola and its 1.866ppm. ie more than double that of the bacopa.

the standards vary significantly. see below: the california standard is the lowest and the bacopa is above the california standard. 1mcg=1ppm
California Proposition 65 Daily Limits for Heavy Metal Consumption
Lead 0.5 mcg (μg)
Arsenic 10 mcg (μg)
Cadmium 4.1 mcg (μg
1mcg=1ppm
FDA Tolerable Daily Diet Lead Intake
Children <6 yrs old 6 mcg (μg)
Pregnant women 25 mcg (μg)
Adults 75 mcg (μg)
Excerpt from the article doing the math on a dosage basis:
>It is extremely important for clinicians to be able to calculate
the potential daily loads of toxic metals from the lab data provided to them. The following steps illustrate how to do this. For simplicity's sake, let’s assume this lab data comes from freeze-driednettle (Urtica dioica) leaf powder that went into capsules, witheach capsule containing 300 mg of the nettle powder.
>1. Determine the typical upper total daily dose. In this
>case, the product is likely to be prescribed at 2 capsules
>3 times per day, a total of 6 caps per day, representing
>1,800 mg (or 1.8 g) of powder.
>2. Let’s assume that test data for the nettle leaf raw material shows it contains lead at 3 ppm.
>3. In the math of toxic analysis, 1 ppm translates to 1 mg
>toxic element/1000 g product (1 mg/1000 g).
>4. Converting 1 mg to 1,000 μg, then 1 mg/1000 g = 1,000
>μg/1000 g.
5. Converted again, 1,000 μg/1000 g = 1 ug/1 g.
6. Thus, 3 ppm…

Well .215mcg is less than .5mcg. I misread the California specs. It's .5mcg for everyone, not just pregnant women. In any event, you are below that limit, even if you dose 2 times per day.
I guess I should ask what percentage bacosides it is, as that will affect your dosage.
