The Institute for Contaminant Standards

An independent standards body for contaminants in food and the supply chain. Each program is backed by its own independent index of the complete scientific literature and a separate certification standard — governed in common, kept independent by a hard data-class firewall.

The evidence base, by the numbers

The standards rest on the complete heavy-metals literature — curated, traceable, and complete within scope. Every figure links to the independent index.

A global problem, unevenly studied

Studies in the corpus none yetmost

Geographic concentration of the scientific literature ICS indexes — study density, not contamination levels. Lighter regions are under-represented in the global literature (a gap ICS is working to fill), not regions shown to be cleaner. Most-studied: US (358) · EU (280) · CN (256) · IR (99) · IN (98) · NG (97). The evidence behind every figure lives on the Heavy Metal Index.

Programs

Heavy Metals

Certification against the complete heavy-metals food-and-supply-chain literature. Ten-analyte panel, published per subcategory in native basis.

MicroplasticsIn development

A contaminant standard for microplastics, in development. The same architecture: an independent literature index and a certification authority, governed in common, firewalled by data class.

The Microplastics program is in development. The same architecture — an independent index and a separate certification standard — applies.

Forever Chemicals (PFAS)In development

A contaminant standard for PFAS, in development. Same model, same firewall — an independent index of the literature and a separate certification standard.

The Forever Chemicals (PFAS) program is in development. The same architecture — an independent index and a separate certification standard — applies.

A deepening, current record

Indexed studies by publication year (corpus coverage over time). Source records on the Heavy Metal Index.

Independence is the product

ICS does not test products and does not sell a badge. It governs standards: how a certification limit is set, how the evidence behind it is kept independent and traceable, how the mark is used, and how enforcement works. The threshold math, the certified-product directory, and the application live on each program's own site; the literature lives on the independent index. ICS describes how those pieces fit and keeps them apart — it publishes no threshold values and no brand-level data itself.
