Residential surface soil guidance values applied worldwide to the original 2001 Stockholm Convention POP pesticides

Is There any Relationship between Worldwide Pesticide Standard Values in Residential Soil, Drinking Water, and Agricultural Commodity Exposures?

“…Previous studies show that median and geometric mean are better measures of PSVs central tendency [4][5][6]. The weighted average medians for soil and drinking water IDLs are 1.09 E-03 and 2.21 E-03 mg/kg-day respectively, and that for food IDLs is 1.17 E-02 mg/kgday.…”

“…Developing PSVs regulations is a systematic and comprehensive work by considering all major exposures and applying the human health risk model. Previous studies [4][5][6] show that worldwide pesticide soil Regulatory Guidance Values (RGVs) are not harmonized, which could vary in five, six, or even seven orders of magnitude. Some RGVs seem too large to prevent human health impact and others are too small to achieve the remediation goal technically.…”

Residential surface soil guidance applied worldwide to the pesticides added to the Stockholm Convention in 2009 and 2011

“…These new POP pesticides and the original "dirty dozen" pesticides discussed in Jennings and Li (2015) have been available for study much longer than their modern descendants. Their potential human health risks are dire and well known, and a great deal of data are available upon which to base their environmental regulation.…”

“…This effort required translating guidance documents from 29 languages and identifying compounds from numerous nomenclature descriptions and product name variations used for pesticide products. Jennings and Li (2015) then examined the RGVs applied to the persistent organic pollutant (POP) pesticides (Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, and Toxaphene) that were among the 12 "dirty dozen" pollutants banned or seriously restricted by the Stockholm Convention of 2001 (Secretariat of the Stockholm Convention, 2008). With the exception of Mirex, all of these are among the 20 most frequently regulated pesticides worldwide (Jennings and Li, 2014).…”

“…In the U.S. as in many other nations, as suburban developments spread into former agricultural lands, residential exposures to these residuals can be surprisingly high. In addition, as discussed in Jennings and Li (2015), there are large stockpiles of "obsolete" pesticides in at least 93 nations totaling nearly 300,000 metric tons (Food and Agricultural Organization of the United Nations, 2014). Much of this total is made up of POP pesticides.…”
