What makes pesticides hazardous

By doing this, I know that my food is not being sprayed with chemicals, and it tastes a lot fresher.

The Dangers of Pesticides. Rodenticides Pesticides and the Environment Even though pesticides are sprayed on land, many times, they can make their way into a water source, such as a river, ocean, or pond. So why are pesticides so harmful to people's health? July 23, AM. Posted By: Robert Beatty.

To quote the EPA: " Pesticides derived from natural sources e. Sorry, but if you want to go pesticide free, it's not as easy as buying organic. More over, the level of usage when it comes to approved organic pesticides could very well mean a better general rule of thumb is to go non-organic. But, of course, that would just be a rule of thumb and not an end-all. The only sure route is to know exactly where your food comes from and what pesticides, if any, they use.

Establishing a baseline value often requires two tests performed at least 72 hours apart but within 14 days of each other. If the test results differ by as much as 20 percent, a third test is often recommended. Cholinesterase tests can be repeated during times when organophosphate and carbamate insecticides are being used and then compared with the baseline level. The purpose of routine cholinesterase monitoring is to enable a physician to recognize the occurrence of excessive exposure to organophosphates and carbamates.

If a laboratory test shows a cholinesterase drop of 30 percent below the established baseline, the worker should be retested immediately.

If a second test confirms the drop in cholinesterase, the pesticide handler or agricultural worker should be removed from further contact with organophosphate and carbamate insecticides until cholinesterase levels return to the preexposure baseline range. Your primary care physician can help to establish the frequency of this testing program. Ideally, use a low-toxicity product when possible, but even they can be harmful if your exposure level is high.

However, regardless of the product's toxicity, if the exposure level is low, then the hazard will also be low. To reduce the possibility of exposure and to protect your health, always wear the personal protective equipment PPE as indicated on the product label. The following are general PPE guidelines to protect against the four routes of entry. More than 95 percent of all exposures are dermal. Dermal absorption may occur as the result of a splash, spill, or drift or when cleaning or repairing equipment.

Wear unlined, chemical-resistant gloves to eliminate most dermal exposures. Minimum dermal protection for most pesticides consists of a long-sleeved shirt, long trousers, gloves, and proper footwear. For extra precaution, consider wearing coveralls, a waterproof hat, and unlined rubber boots. Additionally, wearing a liquid- proof apron or rain suit is recommended when mixing and pouring concentrates or when using highly toxic products.

For many toxic chemicals, the respiratory breathing system is the quickest and most direct route of entry into the circulatory system. Respiratory protection is especially important when pesticide powders, dusts, gases, vapors, or small spray droplets can be inhaled.

Use the respirator as designed for its intended use, and always follow the manufacturer's instructions. Accidental oral exposure most frequently occurs when pesticides have been taken from the original container and put into an unlabeled bottle or food container. Unfortunately, children are the most common victims in these situations.

Store pesticides only in their original containers, and keep the original label attached to the container. Store pesticides only in their original containers and keep the original label attached to the container. Never use your mouth to clear a spray line or to siphon a pesticide from a tank or container. After handling or working with pesticides, wash your hands and face thoroughly with soap and water before eating, drinking, or smoking.

Eyes are very sensitive to many pesticides and, considering their size, are able to absorb large amounts of chemical. Serious eye exposure can result from a splash, spill, or drift or by rubbing the eyes with contaminated hands or clothing. Tight-fitting chemical splash goggles or a full-face shield should be worn if there is any chance of getting pesticides in the eyes, especially when pouring or mixing concentrates and handling dusts.

When pouring from a container, keep the container below eye level to avoid splashing or spilling chemicals on your face or protective clothing. All pesticides have the potential to be harmful to humans, animals, other living organisms, and the environment if used incorrectly.

The key to reducing health hazards when using pesticides is to always limit your exposure by wearing PPE and use a low-toxicity pesticide when available. Reading the label and practicing safe work habits will minimize hazards from the use of pesticides.

Pesticide Toxicity and Exposure Hazard, or risk, of using pesticides is the potential for injury, or the degree of danger involved in using a pesticide under a given set of conditions. Acute Toxicity and Acute Effects Acute toxicity of a pesticide refers to the chemical's ability to cause injury to a person or animal from a single exposure, generally of short duration.

Chronic Toxicity and Chronic Effects The chronic toxicity of a pesticide is determined by subjecting test animals to long-term exposure to the active ingredient. Symptoms of Pesticide Poisoning The symptoms of pesticide poisoning can range from a mild skin irritation to coma or even death.

Seeking Medical Attention Be alert for the early signs and symptoms of pesticide poisoning in yourself and others. Harmful Effects of Some Pesticide Families Fungicides The acute toxicity of fungicides to humans is generally considered to be low, but fungicides can be irritating to the skin and eyes.

Table 2. Signs and symptoms of acute exposure for several fungicide active ingredients. Allergic contact dermatitis. Copper Compounds Bordeaux mixture, Copper sulfate Irritating to skin, eyes, respiratory tract. Salts are corrosive to mucous membranes and cornea Metallic taste, nausea, vomiting, intestinal pain. Skin disease in occupationally exposed individuals. Breath odor of rotten eggs. Irritant dermatitis in occupationally exposed individuals Thiram Polyram-Ultra, Spotrete-F Irritating to skin, eyes, respiratory mucous membranes Ziram Cuman, Vancide Irritating to skin, eyes, respiratory tract Prolonged inhalation causes neural and visual disturbances Herbicides In general, herbicides have a low acute toxicity to humans because the physiology of plants is so different than that of humans.

Pesticides are designed to in most cases kill pests. Many pesticides can also pose risks to people. Generally, however, people are likely to be exposed to only very small amounts of a pesticides — too small to pose a risk. To determine risk, one must consider both the toxicity or hazard of the pesticide and the likelihood of exposure.

A low level of exposure to a very toxic pesticide may be no more dangerous than a high level of exposure to a relatively low toxicity pesticide, for example.

The health effects of pesticides depend on the type of pesticide. Some, such as the organophosphates and carbamates, affect the nervous system. Others may irritate the skin or eyes.

Some pesticides may be carcinogens. Others may affect the hormone or endocrine system in the body.
