It is illegal for companies to make such claims. Registration merely indicates that the active ingredients will perform as intended. There is very little research on the synergistic effects of exposure to multiple chemicals, as is the case in real life situations. Slowly, we are beginning to recognize some of the health risks associated with everyday chemicals. Many products contain estrogen mimicking compounds which are increasingly associated with cancers and disorders of the reproductive systems, including breast and prostate cancer.
Some chemicals can have a negative impact on the offspring a decade or more after parental exposure.
Pesticides are further implicated in birth defects, infertility, suppression of the immune system, childhood cancers, and some cancers commonly found among farm workers. Neurotoxic chemicals in pesticides are designed to kill or diminish some life form. Exposure to small doses over extended periods of time can be a major health risk for people, particularly children. The neurotoxic effects can result in attention deficit disorder, behavior problems, leaming disabilities, loss of mentation, as well as headaches, nausea and vomiting. Experiments are not done directly on human subjects making it difficult to prove without a doubt, the cause and effect relationship.
