Corrigendum to “Existing land use and extent of lead (Pb) contamination in the grazing food chain of the closed Carmona sanitary landfill in the Philippines” [Heliyon 5 (5) (May 2019) e01680]

In the original published version of this article, the first statement in section 2.5 (Data analysis) incorrectly read "A paired sample T-test was conducted […]". This was incorrect and should have read “An independent sample t-Test was conducted […]”. Additionally, to align with the accurate t-Test analysis that was used in this study, several other statements present in the manuscript were incorrect and should be updated: in section 3.3 (Soil contamination level) the sentence reading “The t-Test: paired two samples for means analysis showed […]” should read “The independent sample t-Test analysis showed […]”; in section 3.4 (Plant, insect, and chicken's liver contamination level) the sentence reading “The t-Test: paired two samples for means analysis revealed that […]” should read “The independent sample t-Test analysis revealed that […]”. Finally, in table 3, the value “2.50” in column “t stat," row “Liver (Sample 3)” should instead have read “5.5”. The authors apologise for this mistake. This correction does not, in any way, compromise the findings of the study, either in terms of the methodology, results, or interpretations drawn from the data therein. Both the HTML and PDF versions of the article have been updated to correct the error.
