Uptake of Heavy Metals by Algae

The removal of heavy metals from aqueous solutions is an important issue faced by industries discharging wastewater containing heavy metals. Because of rapid industrialization, an alarming amount of toxic heavy metals has been released into the environment, endangering natural ecosystems and public health. Researchers have been looking at the uptake of heavy metals by algae – various different species.

Thousands of tons of lead are discharged from electric battery manufacturing, lead smelting, internal combustion engines fuelled with leaded petroleum, and mining activities. Lead affects the human central
nervous system, the blood pressure and the reproduction.

The accumulation of metals by algae, bacteria, fungi and yeast has been extensively studied in the last two decades. Of the microorganism studied, algae are gaining increasing attention, due to the fact that algae, particularly marine algae, are a rich source in the oceanic environment, relatively cheap to process and able to accumulate high metal content.

This research study represents a comparative uptake study of the toxic elements arsenic, boron, copper, manganese and zinc in monometallic and multimetallic solutions by four green microalgae species (Chlamydomonas reinhardtii, Chlorella vulgaris, Scenedesmus almeriensis and an indigenous Chlorophyceae spp.), evaluating the effect of pH and contact time. Maximum removal efficiencies for each toxic element were 99.4% for Mn (C. vulgaris, pH 7.0, 3 h), 91.9% for Zn (Chlorophyceae spp., pH 5.5, 3 h), 88% for Cu (Chlorophyceae spp., pH 7.0, 10 min), 40.7% for As (S. almeriensis, pH 9.5, 3 h) and 38.6% for B (S. almeriensis, pH 5.5, 10 min). B removal efficiencies decreased remarkably in multimetallic solutions (down to 0.2% in C. reinhardtii), except for Chlorophyceae spp., the only species isolated from a polluted environment. FTIR spectra shown the highest interactions for As (1150-1300 cm^-1) and Cu (3300, 1741, 1535, 1350-1400 cm^-1). Results confirm microalgae biomass as a potential biosorbent for toxic elements.

Check your mercury levels

If you have concerns about your mercury consumption, there is a simple Hair Tissue Analysis that you can do to determine not only mercury levels but many other toxic metals, as well as a full mineral profile.

Natural Toxic Metal Elimination

Reading this article, one can conclude that if you have been eating fish, the likelihood is that you have some methylmercury stored in your body, with all the health consequences this entails.

This is why it is important to begin a toxic metal detox protocol for all the family. The question, is what is the best choice of a heavy metal detox product as there are so many on the market?

It is best to eliminate heavy metals naturally using a proven toxic metal formulations such as HMD™.
