Negative Effects of pesticides on the environment
Target specific pesticides and Broad specific pesticides
Target specific pesticides specifically kill a certain type of insect or the family of insect while broad specific pesticides can kill an arrange of insects. Target specific pesticides contain toxins that are safe to be ingested by other organisms living in that ecosystem, but dangerous to anything outside the specific zone. Brodifacoum is a rodenticide that only targets rodents and the toxins within can harm specific amount of animals outside of its specific zone. A broad spectrum pesticide like chlorpyrifos targets a wide range of insects like roundworms, mosquitoes and termites, also a broad spectrum pesticide can be very toxic to a lot of other organisms, due to its less specific range.
Lethal Dose and Lethal Concentration
Most often appears as LC50 and LD50, the 50 is symbol to show 50 percent chance of death of the toxins when ingested all, measured in milligrams. LD50 is used to measure and describe the acute toxicity of a product or material. We use LD50 because it helps us identify different types of toxins and the acute toxicity of them, because not all toxins are the same due to the presence of different chemicals. LC50 environmentally speaking is chemical concentration of water and has 50 percent chance in killing organism if ingested all.
Pesticide consideration and grasshopper, drift effect
Pesticides in large concentrations can be very detrimental to the environment it's put into, it has the ability contaminate the soil, water, plants and organisms in the environment due to its ability to acidifi many materials . It is recommended not to put an abundant amount of pesticide in an area, due it its effects. There are many for pesticides to be spread two being the grasshopper and drift effect, when spraying pesticides on crops and soil when a wind current is present can be harmful to areas surrounding the target zone, the wind can transfer pesticides into bodies of water not intended to be sprayed, or specific crops not intended to be spread either. The grasshopper effect occurs by evaporation and condensation, the pesticides or POPs (persistent organic pollutants) travel from warmer climates to colder, through evaporation the pesticides are picked up in warmer climates and are transported by condensation in colder climates.
Environmental persistence and the effects
Environmental persistence occurs when a POP resists environmental degradation which is the decline of an environment when the resources within the environment also decline or lack. POPs resist environmental degradation through chemical and biological processes. These toxins are able to linger and move to other environments and are able to bio accumulate and progress through an ecosystem's food chain and ultimately end up as consumable for humans, which can cause sickness and poisoning.
Pest resistance and the effects
Pest resistance occurs when pest begin to mutate and ignore the effects of pesticides that killed other previous pest, this is bad because without pesticides the pest are able to ruin the crops that were suppose to be protected. Most farmers don’t notice the resistance until it's too late and many valuable crops have been destroyed.
Government regulations on pesticides
Almost all pesticides are controlled by the pest regulatory management agency of Canada, multiple studies need to completed to assess whether the pesticide is safe for the Canadian consumer, almost 200 screenings are done by scientist that observe the pesticide's effectiveness and behavior. Once the product is in stores it must still need to be re evaluated by the pest regulatory management agency of Canada. In order for a product to be regulated the records of the pesticides must be shared by the federal, municipal, territorial and provincial government.
Alternatives to pesticides
An alternative to using pesticides would be the use of hormones,when the hormones are spread in the air near an area outside of the specific crop zone, the male insects will be confused and will search for the females they feel are near due to the hormones. This prevents both male and female insects in destroying crops because both are occupied and confused due to the false hormone signals.
