Algerian and Moroccan industries drive air pollution in Canary Islands

Industrial emissions from Algeria and Morocco, including thermal power plants, natural gas factories, and fertilizer plants, are contributing more pollution to the Canary Islands than local vehicle traffic.

A two-year study conducted by the Canary Islands Air Quality Laboratory (AirCanLab)—a joint effort between the Spanish National Research Council (CSIC) and the regional Ministry of Ecological Transition and Energy—analyzed the chemical composition of PM10 particles. The research found that sulfate, ammonium, and nitrate particles from transnational sources reach concentrations of up to 5 micrograms per cubic meter, accounting for approximately 15% of total emissions in the archipelago.

In contrast, soot from local vehicles accounts for only about 5% of emissions, reaching concentrations of 2 micrograms per cubic meter. Scientists noted that these particles are primarily transported to the islands by trade winds. The study focused on PM10 particles, which are small enough to be inhaled and can cause significant pulmonary damage.
