Pesticides and its effects



Pesticides
Pesticides are the only toxic substances released intentionally into our environment to kill living things. This includes substances that kill weeds (herbicides), insects (insecticides), fungus (fungicides), rodents (rodenticides), and others.
The use of toxic pesticides to manage pest problems has become a common practice around the world. Pesticides are used almost everywhere -- not only in agricultural fields, but also in homes, parks, schools, buildings, forests, and roads. It is difficult to find somewhere where pesticides aren't used -- from the can of bug spray under the kitchen sink to the airplane crop dusting acres of farmland; our world is filled with pesticides. In addition, pesticides can be found in the air we breathe, the food we eat, and the water we drink.
People often use pesticides in their homes or yards to control a variety of pests such as insects, weeds and rodents. Pet owners may also apply pesticide products directly to their pets to control ticks and/or fleas. Although these pesticides can be beneficial, they have the potential to hurt your pet if they are not stored and used properly.

EFFECTS
Pesticides and Human Health
Pesticides have been linked to a wide range of human health hazards, ranging from short-term impacts such as headaches and nausea to chronic impacts like cancer, reproductive harm, and endocrine disruption.
Acute dangers - such as nerve, skin, and eye irritation and damage, headaches, dizziness, nausea, fatigue and systemic poisoning - can sometimes be dramatic, and even occasionally fatal.
Chronic health effects may occur years after even minimal exposure to pesticides in the environment, or result from the pesticide residues which we ingest through our food and water.
Pesticides and Children
Children are particularly susceptible to the hazards associated with pesticide use. There is now considerable scientific evidence that the human brain is not fully formed until the age of 12, and childhood exposure to some of the most common pesticides on the market may greatly impact the development of the central nervous system. Children have more skin surface for their size than adults, absorb proportionally greater amounts of many substances through their lungs and intestinal tracts, and take in more air, food and water per pound than adults. Children have not developed their immune systems, nervous systems, or detoxifying mechanisms completely, leaving them less capable of fighting the introduction of toxic pesticides into their systems.
Many of the activities that children engage in - playing in the grass, putting objects into their mouth and even playing on carpet - increase their exposure to toxic pesticides. The combination of likely increased exposure to pesticides and lack of bodily development to combat the toxic effects of pesticides means that children are suffering disproportionately from their impacts
Pesticides and the Environment
Pesticides are toxic to living organisms. Some can accumulate in water systems, pollute the air, and in some cases have other dramatic environmental effects. Scientists are discovering new threats to the environment that are equally disturbing.
The Solution to Pesticides
We need to make our food, our air, our water, and our soil free from toxic chemicals.
The real solution to our pest and weed problems lies in non-toxic and cultural methods of agriculture, not in pulling the pesticide trigger. Organically grown foods and sustainable methods of pest control are key to our families’ health and the health of the environment.
Better testing. State and federal agencies should require stricter independent testing, including testing of synergistic effects of pesticides. Pesticides known or suspected of causing human health problems should be phased out.
Protect our children. Because our children are the most vulnerable population to pesticides, pesticide use should be prohibited in places where our children live and play, including schools, parks, and playgrounds. Require strict non-toxic pest management programs for such places.
Pesticide Use Reduction. Provide technical assistance to farmers, local governments, businesses, and homeowners on non-toxic alternatives to pesticide use. This includes alternatives to nuisance spraying for mosquitoes and controlling West Nile virus and other pest problems.
Prohibit pollution of our water and poisoning of our communities. Ensure that aerial pesticide use does not pollute our waterways through strict rules governing spraying and buffer zones that prevent the harmful effects of drift. Prohibit the use of pesticides for purely aesthetic reasons. Prevent pesticide applications to water bodies, instead using non-chemical methods of managing aquatic invasive weeds.
Right to know. Provide free and universal notification to residents about pesticide use, including who is using chemicals, where, when, how, what pesticides are being used, and why.
Protect workers. Provide protection to workers and farmers to prevent acute and chronic pesticide poisoning.
