The 1st International Seminar on Pollution, Health, Environment and Biomonitoring Abstract book SIPSEB 2021

International audienceThe first international seminar on pollution, health, environment and bio-monitoring, will be organized by the Department of Science and Nature and Life of the University of August 20, 1955-Skikda online (web meeting); this is in projection of the effect of Covid-19 pandemic. Public health, the appearance or disappearance of certain living species, pollution, climate change, etc… can be among the batteries of environment health indicators. They are the most objective natural integrators of an environmental state, and therefore, of the impacts of human activities combined with possible natural bio-geo-climatic hazards. Bio-monitoring is very useful in the context of environmental public health. Thereby, knowing the origin of our food and its qualities is essential for our health. Namely that fishery and aquaculture products make an important contribution to food security and nutrition; they are the main source of protein for 17% of the world’s population and almost 25% in low-income and food-deficit countries. The Committee on World Food Security (CFS, 2014) recognized; the sustainability of fisheries and aquaculture was an essential condition for food security and nutrition. As a result, this seminar aims to bring together researchers and teacher-researchers and why not professionals from all over the country so that they can discuss and share their scientific results and field experiences in relation to the themes proposed for this seminar as: Marine Sciences, Ecotoxicology, Applied Microbiology, Food Quality and Safety and HACCP, Pathology of Fishery and Aquaculture Products, Pollutants’ Impact on Human Health, Consumer Protection, ISO upgrade and Blue Biotechnology

Management of toxic cyanobacteria for drinking water production of Ain Zada Dam

International audienceBlooms of toxic cyanobacteria in Algerian reservoirs represent a potential health problem, mainly from drinking water that supplies the local population of Ain Zada (Bordj Bou Arreridj). The objective of this study is to monitor, detect, and identify the existence of cyanobacteria and microcystins during blooming times. Samples were taken in 2013 from eight stations. The results show that three potentially toxic cyanobacterial genera with the species Planktothrix agardhii were dominant. Cyanobacterial biomass, phycocyanin (PC) concentrations, and microcystin (MC) concentrations were high in the surface layer and at 14 m depth; these values were also high in the treated water. On 11 May 2013, MC concentrations were 6.3 μg/L in MC-LR equivalent in the drinking water. This study shows for the first time the presence of cyanotoxins in raw and treated waters, highlighting that regular monitoring of cyanobacteria and cyanotoxins must be undertaken to avoid potential health problems
