Question

observation of avoid use of chemical pesticides

Answer 1

 By including information on chemicals in use during this period, we can characterize recent (observed) exposure for that individual. By these steps, the degree of risk may be determined for recent (observed) exposure. An estimate of long-term risk resulting from work-related exposures can be obtained for individuals by summing across their work histories. Keywords:exposure assessment, toxic impairment, pesticides, neurobehavioral impairment, cognitive impairment, human.

Answer 2

Answer:

Explanation:

Chemical pesticides are known to pollute the environment. While their intended effects are often short-lived, studies have shown that chemical pesticides linger in the atmosphere, the ground and in our waterways long after the job is over. Chemicals have been used on fields across the world for almost 100 years, creating a buildup of adverse pollution in our environment, which continues to grow with every application.

Unfortunately, when pesticides are applied onto a surface, they travel outside their intended area of use by air, soil or water. This is one common way in which chemical pesticides cause collateral damage, beyond their intended use. The Agricultural MU Guide, Pesticides and the Environment, explains that "for certain pesticides to be effective, they must move within the soil…too much movement can transfer a pesticide away from the target pest. This can lead to reduced pest control, contamination of surface water and groundwater and injury of non-target species, including humans."

Organizations like the Organic Material Review Institute (OMRI) have been taking strides in recent years to develop standards for these alternative products. The private nonprofit group is in charge of determining whether a product, such as a repellent, may qualify as organic. Unlike chemical pesticides, each approved organic product must pass a set of rigorous standards to comply with USDA organic regulations. The criteria for these organic-certified products are put in place to reduce negative effects to people, animals, and the environment.

While all types of pesticides are known to travel, organic products are less harmful in composition, thus minimizing or even eliminating residual damage. Supporting the use of food-based organic repellents (e.g. putrescent eggs, capsaicin) will help eliminate potentially harmful chemical pesticides from the marketplace, and ultimately from the food we consume.
