{"cited_by_count":258400,"description":"This cluster of papers covers the chemical and biological technologies for controlling odors, with a focus on managing emissions of hydrogen sulfide, volatile organic compounds, ammonia, and siloxanes. It explores bioreactors, biofiltration, microbial communities, and concrete corrosion in sewer systems and waste gas treatment. The papers also discuss the sulfur cycle, odor measurements, health risk assessment, and environmental impacts.","display_name":"Odor and Emission Control Technologies","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T11821","wikipedia":"https://en.wikipedia.org/wiki/Odor_control"},"field_id":"15","id":"T11821","keywords":[{"display_name":"odor control","id":"odor-control","score":0.5202,"url":"https://openalex.org/keywords/odor-control"},{"display_name":"ammonia emissions","id":"ammonia-emissions","score":0.2472,"url":"https://openalex.org/keywords/ammonia-emissions"},{"display_name":"odor emissions","id":"odor-emissions","score":0.6699,"url":"https://openalex.org/keywords/odor-emissions"},{"display_name":"biofilter","id":"biofilter","score":0.3117,"url":"https://openalex.org/keywords/biofilter"},{"display_name":"biofiltration","id":"biofiltration","score":0.4178,"url":"https://openalex.org/keywords/biofiltration"},{"display_name":"biotrickling filter","id":"trickling-filter","score":0.4141,"url":"https://openalex.org/keywords/trickling-filter"},{"display_name":"elimination capacity","id":"elimination-capacity","score":0.8465,"url":"https://openalex.org/keywords/elimination-capacity"},{"display_name":"VOC removal","id":"voc-removal","score":0.2007,"url":"https://openalex.org/keywords/voc-removal"},{"display_name":"odor measurement","id":"odor-measurement","score":0.603,"url":"https://openalex.org/keywords/odor-measurement"},{"display_name":"odor pollution","id":"odor-pollution","score":0.5228,"url":"https://openalex.org/keywords/odor-pollution"},{"display_name":"odor intensity","id":"odor-intensity","score":0.2641,"url":"https://openalex.org/keywords/odor-intensity"},{"display_name":"odor nuisance","id":"odor-nuisance","score":0.5438,"url":"https://openalex.org/keywords/odor-nuisance"},{"display_name":"empty bed residence time","id":"empty-bed-residence-time","score":0.8746,"url":"https://openalex.org/keywords/empty-bed-residence-time"},{"display_name":"olfactometry","id":"olfactometry","score":0.2902,"url":"https://openalex.org/keywords/olfactometry"},{"display_name":"biological air treatment","id":"biological-air-treatment","score":0.844,"url":"https://openalex.org/keywords/biological-air-treatment"},{"display_name":"odor compounds","id":"odorous-compounds","score":0.3853,"url":"https://openalex.org/keywords/odorous-compounds"},{"display_name":"odor monitoring","id":"odor-monitoring","score":0.6107,"url":"https://openalex.org/keywords/odor-monitoring"},{"display_name":"odour nuisance","id":"odour-nuisance","score":0.5661,"url":"https://openalex.org/keywords/odour-nuisance"},{"display_name":"odor concentration","id":"odor-concentration","score":0.4138,"url":"https://openalex.org/keywords/odor-concentration"},{"display_name":"odor evaluation","id":"odor-assessment","score":0.3934,"url":"https://openalex.org/keywords/odor-assessment"},{"display_name":"hydrogen sulfide emissions","id":"hydrogen-sulfide-emissions","score":0.3432,"url":"https://openalex.org/keywords/hydrogen-sulfide-emissions"},{"display_name":"toluene removal","id":"toluene-removal","score":0.2838,"url":"https://openalex.org/keywords/toluene-removal"},{"display_name":"livestock odor","id":"livestock-odor","score":0.8207,"url":"https://openalex.org/keywords/livestock-odor"},{"display_name":"air treatment","id":"air-treatment","score":0.2067,"url":"https://openalex.org/keywords/air-treatment"},{"display_name":"dynamic olfactometry","id":"dynamic-olfactometry","score":0.7864,"url":"https://openalex.org/keywords/dynamic-olfactometry"}],"legacy_keywords":["Odor Control","Bioreactors","Sulfur Cycle","Volatile Organic Compounds","Ammonia Emissions","Siloxanes","Biofiltration","Concrete Corrosion","Microbial Community","Waste Gas Treatment"],"openalex_id":"https://openalex.org/T11821","source_created_date":"2024-01-23T15:27:12","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1508","url":"/topics/T11821","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11821","works_count":36697,"label":"Odor and Emission Control Technologies","provider":"openalex","revision":"25649da1bef14f58","taxonomy_revision":"f050b5d4780b1289","title":"Odor and Emission Control Technologies","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36183296736013883","address_version":"morton4x16-v1","coordinates":[3,15,1508,11821],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
