Abstract The presented work is devoted to the study of the ecological potential of Spirulina Arthrospira platensis to absorb copper ions from the water polluted by given heavy metal. The obtained data reveal the ability of Spirulina in a short time, in particular for 3 days to diminish 70% of Cu2+ ions of the initial incubation medium (100 ppm). The physiological parameters of Spirulina under the influence of copper on algae were also studied the highest concentration of Cu2+ ions cause inhibition of biomass accumulation by 15% and decrease of chlorophyll content by 30%. The presented results underline the capacity of Arthrospira platensis for the purification of water contaminations by copper. Keywords Phytoremediation . Spirulina . Water pollution . Copper ions

technologies. New challenges to human life and natural resources need overcome as urban populations are expected to grow in the coming decades (Frieman et al. 1999). In every country, with the exception of highly developed ones, wastewater flows straight into the environment without any treatments that cause danger to human health, crop quality, soil fertility, and the whole ecosystem (Cho 2011). Integrated urban water management (IUWM) addresses issues that 80% of wastewater is still discharged untreated and helps cities’ progress to a circular economy (Kim 2018). Low-quality water damages crop production and dangerous our food which is harmful to human life (Khan and Ghouri 2012). Adequate and clean drinking water is necessary to ensure human health. Human activities increase the risk of water pollution which directly leads to a reduction in biodiversity and socio-economic development (Kim 2018). The cause for 3.1% of deaths is the unhygienic and poor quality of water (Qadri and Faiq 2019). Ten percent of residents consume poisoned food and herbs that irrigated by contaminated water. Almost 90% of sewage water flows into rivers and seas without treatment in most developing countries. Currently, there is no global monitoring of wastewater management, which is a prerequisite for better health development (Eid 2015). General sources of contaminated
