SUMMARY:

Lead (Pb) is one the 10 chemicals of major public health concern listed by WHO, being associated with toxicity in all organs. One reason for Pb occurrence in food are agricultural practices, for instance, when pesticides containing Pb are used. In this context, organic production systems are highlighted for not using pesticides. Considering that, a systematic review (SR) aiming to gather evidence to answer if there are differences in Pb levels in conventional and organic leafy vegetables is being conducted. PRISMA-P 2015 and its checklist were used for guidance in the construction of the protocol for this SR, which has been registered on the PROSPERO platform under code CRD42022306048. PECOS was used as a guiding acronym of the present study and of its eligibility criteria, referring to the population (organic leafy vegetables), exposure (occurrence of Pb), comparator (conventional leafy vegetables), outcomes (occurrence of Pb in leafy vegetables from both production systems, and secondary outcomes), and study type (studies reporting primary data). Thus, only analytical, cross-sectional studies which report data on the analysis of Pb in conventionally and organically grown leafy vegetables have been included. Searches were run on 12 electronic databases: AGRICultural OnLine Access (AGRICOLA), CAB Direct, Embase, Food Science and Technology Abstracts (FSTA/EBSCO), GALE Academic OneFile, Google Scholar, International System for Agricultural Science and Technology (AGRIS), Latin American and Caribbean Health Sciences (LILACS), Medline (OVID), ScienceDirect (Elsevier), Scopus, and Web of Science. No restriction was applied regarding language or publication period. Registers resulting from searches on the databases (n=3,291) were imported into the application Rayyan Intelligent Systematic Review, which was used for study selection in various phases, namely removal of duplicates, screening of titles and abstracts, and full reading of studies, phases in which respectively 1,122, 2,095 and 44 records were removed. Nine records could not be retrieved for full reading despite several systematic attempts to contact authors, institutions and journals. Thus, a total of 21 studies were included. Currently, this RS is in the phases of data extraction and risk of bias assessment of the included studies, the last being performed through the use of the Joanna Briggs Institute critical appraisal checklist for studies reporting prevalence data. GRADE will be used for assessing the quality of scientific evidence. Data will be evaluated regarding heterogeneity, which will determine whether meta-analysis will be feasible. From a Public Health perspective, this SR classifies as a health surveillance action, for it will allow comparing Pb levels in conventional and organic leafy greens, relevant discussions on food safety, sustainability and human health, and potential support to establish public policies targeted at more environment-friendly production systems.
