The bilingual course addresses urban and industrial wastes, including the main pollutants appearing in air and wastewater systems. Several aspects such as pollutant origin (sources and formation mechanisms), dispersion processes, environmental and health impact, and risk assessment are covered. Special attention is given on green engineering and its close relation to sustainable development. The program is divided into the following blocks: I. General concepts about environment, sustainability, pollution and effluent treatment, and green chemistry. II. Air pollution, its sources, analysis, treatment, transport and dispersion pollutants atmospheric, impact on health. III. Water pollution, sources, analysis and treatment
