Hidden Dangers of “Inert” Ingredients in Herbicides

Safe?

It is not widely known that no pesticide manufacturer in the United States (as determined by the Environmental Protection Agency) is allowed to call its product "safe." When a pesticide passes the scrutiny of the EPA, it simply means that that product is effective and does kill the organism that its label says it kills. Also, while some information on toxic effects is made available by manufacturers, there is no legal requirement to provide such toxicity data on "inert" ingredients, only active ones.* This is a serious gap in the data of potential chemical effects since some products are more than 99 per cent inert ingredients.  Inerts usually make up at least half if not most of consumer pesticide products. Of the 85 pesticide products examined by the New York Attorney General's office, 75 percent contained over 90 percent inert ingredients.  ** Thus, risk assessments that are based on active ingredients alone can be misleading and serve to downplay the detrimental effects of the products under consideration. Further, a chemical that is used as an “inert” ingredient in one product can sometimes be found as an active ingredient in another. In some cases, the inert ingredients may be more toxic than the active ingredients. *** (See the second excerpt below from the report summary of  Worst Kept Secrets:  Toxic Inert Ingredients in Pesticides, by the Northwest Coalition for Alternatives to Pesticides.)

The Secret Hazards of Pesticides: Inert Ingredients

Look at any label on a pesticide product and you will find a list of "active" ingredients, with a few long chemical names, and then typically the phrase "inert ingredients," with only a single percentage figure given and no listing of individual ingredients. The active ingredients are the chemicals used to control the target pest and must be listed on the label. The so-called "inert" ingredients are used as carriers for the active ingredients, to help dissolve them, make them easier to apply or to preserve them.

Unfortunately, many people will conclude from the term "inert" that such ingredients could not possibly have any adverse health or environmental effects. This is not the case at all. The chemicals used as inerts include some of the most dangerous substances known. Some of these chemicals are suspected carcinogens and have been linked to other long-term health problems like central nervous system disorders, liver and kidney damage and birth defects. They can also cause short-term health effects like eye and skin irritation, nausea, dizziness and respiratory difficulty…. Although EPA has published a list of chemicals used as inerts, this list does not tell consumers which products contain these inerts. Furthermore, pesticide manufacturers are not required to list all inerts on the product label. Thus, people must play blind man's bluff when it comes to which inerts might be in the pesticides they buy or are used where they live, work or play. (Emphasis added)

Inerts usually make up at least half if not most of consumer pesticide products. For instance, 99.1 percent of Raid's Ant and Roach Killer is inert ingredients and Ortho Diazinon Dust is 96 percent inerts. Of the 85 pesticide products examined by the Attorney General's office, 75 percent contained over 90 percent inert ingredients (see Table 1 on page 7 for a list of these products). Despite the health effects EPA associates with inerts, people do not know to which chemicals they may be exposed since inerts are not identified on the label. Health effects of some inert ingredients are listed in Table 2 on page 9.

Pesticides are widely used throughout the United States in non-agricultural settings--in homes, outside homes, in offices, schools, and recreational areas. Over 70 million pounds of pesticides are applied on lawns alone every year. The use of lawn care pesticides is increasing at about 5 to 8 percent annually. In fact, four times as many pesticides are used on home lawns as are used to grow food crops. Commercial lawn care is now a $1.5 billion industry. In addition, according to a 1985 study, pesticides used on golf courses accounted for nearly 12 million pounds nationwide. And all these pesticide products--whether used in lawn care, household fumigation, pet care or in personal-care products like insect repellents--contain substantial amounts of inert ingredients.

The excerpt below is from the report summary of  Worst Kept Secrets:  Toxic Inert Ingredients in Pesticides, by Northwest Coalition for Alternatives to Pesticides.***

Over 650 chemicals that have been identified as hazardous by federal, state, or international agencies are hiding behind the misleading word "inert" in pesticide products, according to a report released by the Northwest Coalition for Alternatives to Pesticides. Worst Kept Secrets: Toxic Inert Ingredients in Pesticides [PDF 150k] documents the hazards of so-called "inert" ingredients, over 2,500 substances that are added to pesticides but are not named on product labels. Regulatory agencies have few requirements for toxicological or ecological effects testing of inerts. Despite this lack, the new report shows that over 25% of the chemicals used as "inerts" actually have been identified as hazardous.

 

Inerts pose a wide variety of hazards, according to the new report. Almost 400 inert ingredients are now or have been used as the active, killing ingredient in pesticides. In addition, 209 are hazardous air or water pollutants, 21 have been classified as carcinogens, and 127 are occupational hazards. Many have been identified by more than one statute or agency. For example, the "inert" ingredient naphthalene is a pesticide active ingredient, a hazardous air pollutant under the Clean Air Act, and a priority pollutant under the Clean Water Act.
