Table 1 Eligibility criteria

From: What evidence exists on the impacts of chemicals arising from human activity on tropical reef-building corals? A systematic map protocol

Include Exclude
Population
 All tropical reef-building coral species (hermatypic scleractinian species, Millepora sp., Heliopora sp. and Tubipora sp.) living in the shallow and the mesophotic zones  Cold-water or deep-water corals
 Ahermatypic corals
 Free-living zooxanthellae (not as symbionts in corals)
 Studies conducted in coral reefs but not about corals (e.g. about coral reef fishes)
Exposure
 All natural, geogenic and synthetic chemicals coming from human activities. Studies assessing the impact of human activities (e.g. river discharge, distance to a dump or to an industrial effluent source, tourism) on corals without reference to a chemical  Studies assessing the impact of chemicals coming from natural sources (e.g. nutrients from guano)
 Studies assessing the impact of sedimentation per se or of physical disturbances on coral
 Marine debris, macro-plastics
Comparator
 Studies comparing population exposed to chemicals and population unexposed to chemicals
 Studies comparing population exposed to chemicals and population prior to exposure to chemicals
 Studies comparing population exposed to a range of concentrations/levels of chemicals
 
Outcome
 All outcomes related to tropical reef-building corals, from molecular level (e.g. gene expression, enzyme activities) to community level (e.g. coral cover, bioerosion, species richness) (Fig. 1)
 Studies reporting evidence of ingestion, concentration or accumulation/uptake of chemicals in the population studied without reporting health consequences
 Studies assessing impacts on coral microbiome/symbionts
 
Language
 All articles written in English or French (in case a title or an abstract could not be found in English or French, it will be directly screened on full-text)  
Type of document
 Journal article, book chapter, report, conference proceeding, Ph.D. or M.Sc. thesis  Presentation, editorial material, letter or news item, conference or meeting abstract, poster
Type of content
 In-situ or ex situ studies  Reviews and meta-analyses, modelling studies without experimental data
