A multiobjective optimization approach to deal with a pollutant emission reduction problem in the manufacturing industry, through implementation of the best available technical options, is presented in this paper. More specifically, attention is focused on the industrial painting of wood and the problem under investigation is formulated as a bicriteria combinatorial optimization problem. A nich...

Highlights Denitrifying woodchip bioreactors treat nitrate-N in a variety of applications and geographies. This review focuses on subsurface drainage bed-style designs (including in-ditch). Monitoring reporting recommendations are provided to advance bioreactor science engineering. Abstract. enhance the natural process denitrification practical way nitrate-nitrogen (N) N-laden water matrices. T...

Highlights Nitrogen loss reduction due to a cover crop tends improve with increased biomass production. Mixed phosphorus results in cold climates where freeze-thaw cycles occur and can increase dissolved losses. Cereal rye was the primary studied tended provide most water quality benefits. Abstract . Mitigating nutrient losses from agricultural fields retains these nutrients for subsequent prod...

This research uses computational modeling to explore another method to increase diesel engine performance while maintaining low pollutant emission levels. Previous studies have shown that injection-rate profiles and injector configurations play important roles on the performance and emissions of particulate and NOx in DI diesel engines. Since the most important engine design parameters, includi...

Abstract Key targets of the sustainable development goals might be in contradiction to each other. For example, poverty alleviation may exacerbate air pollution by increasing production and associated emissions. This paper investigates potential impacts achieving different eradication on typical pollutants China capturing household consumption patterns for income groups locations, linking it Ch...

The Baltic Sea is heavily polluted yet supports major commercial fisheries for cod (Gadus morhua), herring (Clupea harengus), and sprat (Sprattus sprattus). Emissions of persistent organic pollutants, such as polychlorinated biphenyls (PCBs) and DDT, were high during the 1960s and 1970s, and concentrations in fish and other fauna are still significant. Several models of the fluxes of these poll...
