A lot of heavy metals such as lead, arsenic and cadmium are elements which are widely distributed in natural environment. They are emitted to nature environment by natural phenomenon such as weathering and erosion of rock cycle; therefore, certain amounts of heavy metals are inevitably contained in soil and water. In addition, some are emitted to nature environment by industrial activities. Most of animals and plants have taken heavy metals contaminated with soil and water in the process of growth.
As for noxious chemicals contained in food unintentionally, it is agreed internationally that we should reduce the quantity of noxious chemicals by taking a proactively preventative measure implemented through supply chain from production to consumer end to reduce any possible contamination risks for noxious chemicals with reasonable efforts.
Therefore, we use clean underground water flowed from 3,000m-class mountains insulated from the influence of industrial activities for cultivation of chlorella, and we make effort to reduce the contamination risk of heavy metals contained in chlorella in the process of producing.
The contamination risk of heavy metals in chlorella varies according to weather conditions and duration of exposure to sunlight even if they are the same strain. If you would like to know the quantity of heavy metals contained in chlorella, please contact our customer service (Toll-free:0120-737-119). We will provide the related information on analysis values.
