Research of heavy metals

The mode of culture under greenhouse thus in closed environment makes it possible to guarantee a perfect quality of the product with respect to the external pollutants; the analyses regularly practised by a certified laboratory give the following average results:

Elementstest results
Arsenic< 0,05 mg/kg (50 micro g/kg)
Mercury0,01 mg/kg (10 micro g/kg)
Cadmium< 0,02 mg/kg (20 micro g/kg)
Lead< 0,1 mg/kg (100  micro g/kg)

In 2008, the European Commission set new limits on the levels of certain contaminants such as heavy metals in food :

Lead (Pb): 3 mg/kg (EU 629/2008)
Cadmium (Cd) : 1mg/kg (EU 629/2008)
Mercury (Hg) : 0.1mg/kg (EU 629/2008)
Arsenic (As) : 0.7 mg/kg

(UE 629/2008) : See the official EU Journal 03/07/2008

Search for the Aluminium element

The results of analysis in our Chlorella give a presence of aluminum between 2.4 and 3.6 mg / kg of dry matter.

Aluminium3.0 mg/kg3.0 microg/gDIN EN ISA 11885, mod, CON-PV00006, ICP-OES

-On average 3.0 mg / kg or 0.009 mg (9 micro g) for 3 g of chlorella recommended per day

-For comparison, chocolate contains between 6 and 150 mg/kg, or an average of 48 mg/kg (1)


Aluminum is an element widely present on our planet. It is even the 3rd most abundant element in our earth’s crust (8.1%), after oxygen (47%), silicon (28%) and potassium (2.6%).

Aluminum is more abundant than iron (5%), calcium (3.6%), sodium (2.8%), potassium (2.6%) and magnesium (2.1%).

It is therefore normal to find aluminum throughout our environment.

Our main source of aluminum intake is from food. Aluminium compounds are used as additives in foodstuffs. The aluminium concentration of foodstuffs, especially acidic and/or salty food preparations, can be increased by their aluminium packaging. Aluminum is found in beverages; mineral water, fruit juices, wine, beer…, but also in cosmetics, pharmaceutical products… Aluminum is naturally eliminated by the kidneys and intestines.


The health authorities JECFA (2) recommend not to ingest more than 1 mg of Aluminium per kilogram of body mass (for a 60 kg person the maximum recommended level is 60 mg per week), see the report of May 2009, N°35, Aluminium in Food (Risk assessment studies),

The Joint FAO/WHO Expert Committee on Food Additives (JECFA) is an international expert scientific committee administered jointly by the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO). JECFA serves as an independent scientific committee which performs risk assessments and provides advice to FAO, WHO and the member countries of both organizations. The requests for scientific advice are for the main part channelled through the Codex Alimentarius Commission (CAC) in their work to develop international food standards and guidelines under the Joint FAO/WHO Food Standards Programme.

Pesticide residue research

The research of pesticide residues (organochlorines, halogenated fungicides, polychloride of biphenyls, nitrogenous herbicides, pyrethroid and organophosphorus, pesticides with organic nitrogen) gives negative results with the precision of the detection threshold of the apparatus which is 0,005 mg/kg and/or 0,001 mg/kg for the halogenated fungicides

The research of Aflatoxins (B1/B2/G1/G2) did not reveal the presence of any trace (detection threshold 0,1 micro g/kg).

The microbiological state of the environment is perfectly in conformity with the European legislation of food products.

According to the data of the European legislation :

Total number of germs<10 E5 germs/g
Fungi<< 10 E2 germs/g
Molds< 10 E2 germs/g
Col. Germs not detectable / g
Salmonella not detectable / 25 g

Note: Certified analysis reports are provided to professionals for each batch

Notes on heavy metals

The lead content close to the detection limit of the measuring devices is considered to be at trace level. Heavy metals are present in our daily environment, in varying levels depending on where we live (city or country) and our lifestyle: in our food, in the air, in dust, in our tap water.

Lead (Pb):

Depending on where you are, tap water can still too often contain up to 25 micro g/liter of lead, whereas European regulations impose an upper limit of 10 micro g/liter). We absorb on average up to 0.040 mg (40 micro g/d) of lead every day through our food (source AFSSA 2006).

Mercury (Hg):

The following is an excerpt from Afssa – Saisine n° 2002-SA-0014

“Although mercury (Hg) is present in many foods, it is abundant in fish in its most toxic form: methylmercury (MeHg). Therefore, other food sources were considered negligible. Only MeHg presents a danger for pregnant women, not for themselves but for their fetus through in utero exposure and for young children (up to 2 years old, during the period of development of cognitive functions) via breastfeeding and then diversified diet.

Considering however that, for an average weekly consumption of highly contaminated wild fish (95 percentile), contamination essentially contributed by the group of carnivorous, long-lived and fatty pelagic fish such as sea bream, swordfish, marlin, shark, tuna, the intakes of Hg-T and MeHg are higher than the Provisional Tolerable Weekly Intake (respectively 5 micro g/kg bw/w and 3.3 micro g/kg bw/w for the 3-8 year old age group; considering that, for the 3-8 year old age group, the intakes of Hg-T and MeHg are higher than the Provisional Tolerable Weekly Intake (respectively 5 micro g/kg bw and 3.3 micro g/kg bw). c./wk and 3.3 micro g/kg c.wk respectively) for the 3-8 years age group;

It is considered that, based on the available data (toxicological and contamination) and taking into account the dietary habits of the French population, there is no scientific evidence that justifies a reconsideration of the recommendations of fish consumption recommended in the framework of the National Nutrition and Health Program: at least twice a week without forgetting fatty fish (mackerel, herring, salmon, etc.).

However, given the particular sensitivity of the central nervous system to the toxic action of methylmercury during fetal development, as evidenced by experimental or accidental data at very high exposures, pregnant or breastfeeding women and young children may be recommended to favor a diversified consumption of different species of fish without favoring, as a precaution, the consumption of fish likely to present higher levels of methylmercury such as sea bream, swordfish, marlin, shark, tuna.”
