His primary areas of study are Environmental chemistry, Environmental engineering, Persistent organic pollutant, Pollutant and Pollution. In general Environmental chemistry study, his work on Water pollution often relates to the realm of Pah exposure, thereby connecting several areas of interest. His research integrates issues of Water quality, Pesticide and Aquatic ecosystem in his study of Environmental engineering.
His work carried out in the field of Persistent organic pollutant brings together such families of science as Soil water and Soil contamination. His Pollutant study combines topics from a wide range of disciplines, such as Air quality monitoring and Environmental protection. His studies deal with areas such as Hydrology, Waste management and Raw material as well as Pollution.
His scientific interests lie mostly in Environmental chemistry, Ecology, Pollutant, Pesticide and Ecotoxicology. His Environmental chemistry research incorporates elements of Contamination, Persistent organic pollutant, Soil water, Pollution and Nereididae. His Persistent organic pollutant research is multidisciplinary, relying on both Environmental engineering and Environmental protection.
His Polybrominated diphenyl ethers study in the realm of Pollutant interacts with subjects such as Pygoscelis. In his research on the topic of Ecotoxicology, Fishery, Paper mill and Animal science is strongly related with Rainbow trout. As part of the same scientific family, he usually focuses on Water quality, concentrating on Water pollution and intersecting with Drainage basin.
His main research concerns Zoology, Environmental chemistry, Invertebrate, Pesticide and Aquatic ecosystem. His Zoology research includes themes of Environmental effects monitoring and Pollution. His Invertebrate study is concerned with the larger field of Ecology.
Ricardo Barra works on Ecology which deals in particular with Ecosystem. His Pesticide research is multidisciplinary, incorporating elements of Current, Environmental engineering and Pollutant. His study in Polybrominated diphenyl ethers is interdisciplinary in nature, drawing from both Watershed, Contamination, Fish migration, Southern Hemisphere and Oncorhynchus.
Ricardo Barra spends much of his time researching Environmental chemistry, Biomagnification, Trophic level, δ15N and Invertebrate. His research in Environmental chemistry intersects with topics in Taxon and Mucus. His Biomagnification research is multidisciplinary, incorporating perspectives in Aquatic ecosystem, Ecosystem and Wildlife.
