There are many things that can be done to reduce the risk of pesticide contamination. This prompted me to dedicate a post about the dangers of pesticides, and my research surprised me. The half-life is unique to individual products but variable depending on specific environmental and application factors. Being from various sources such as wastewater, landfill leachates, and solid residues, xenobiotics include phenols, plastics, hydrocarbons, paints, dyes, pesticides and insecticides, paper and pulp mills, and pharmaceuticals. (n.d.). LD50 and LC50 values are useful in comparing the toxicities of different active ingredients and different formulations containing the same active ingredient. Control of the contaminant presents a meaningful opportunity for health risk reductions for people served by public water systems. These MSDS should be obtained from either your local pesticide dealer or directly from the chemical manufacturer. In 2016, a petition arose from common concern because it had been banned by the EU.

Local spray advisories are helpful with this. The contaminant is known to occur or there is a high chance that the contaminant will occur in public water systems often enough and at levels of public health concern. The acute oral and dermal LD50 values of commonly used pesticides are listed in the following tables and include acaricides, bactericides, fungicides, herbicides, insect growth regulators, insecticides, nematicides, and plant growth regulators. Humans, animals, aquatic organisms, and plants can be severely threatened by these chemicals. These three chemicals, along with nine other common compounds, caused increased cell death among the embryos. Toxicity Categories for Active Ingredients, Table 2. Pesticides are rather unique among chemicals, in that they are deliberately added to the environment for the purpose of killing or injuring some form of life.

A 2013 report commissioned by the European Food Safety Authority reviewed 600 research studies on pesticides and found the strongest associations with certain cancers, asthma, childhood leukemia and Parkinsons disease, but couldnt draw any firm conclusions. As of April, the EPA is under court order to decide whether to ban chlorpyrifos, which the agency found in 2017 to exceed safe standards of pesticide residue in food and water, by July. EU pesticide laws are the strictest in the world. Keep in mind, an active ingredient may have a high LD50 placing it in a Toxicity Category II, III, or IV but also have corrosive eye/skin effects that take priority and place it in Toxicity Category I. In the U.S., about 10% of the countrys population (approximately 13 million people) rely on water from private wells but the private wells are not regulated under the Safe Drinking Water Act (SDWA).

The chronic toxicity of a pesticide is determined by subjecting test animals to long-term exposure to the active ingredient. BMPs (Best Management Practices) that reduce runoff or soil erosion or increase soil organic matter content, help reduce pesticide transport as well. Overview of Risk Assessment in the Pesticide Program. There is a risk associated with spray drift affecting foodstuffs, such as vegetable gardens, and being consumed.
