“…Once pesticides have been volatilized, they can be carried on air currents away from the treated surface [31]. Some important factors determine the volatilization level of the pesticide [72], including vapor pressure, temperature, humidity, air movement [86], and soil conditions such as texture, organic matter content, and moisture [87]. The higher the vapor pressure, the more volatile the insecticide will be.…”

Pesticides are indispensable in agricultural production. They have been used by farmers to control weeds and insects, and their remarkable increases in agricultural products have been reported. The increase in the world’s population in the 20th century could not have been possible without a parallel increase in food production. About one-third of agricultural products are produced depending on the application of pesticides. Without the use of pesticides, there would be a 78% loss of fruit production, a 54% loss of vegetable production, and a 32% loss of cereal production. Therefore, pesticides play a critical role in reducing diseases and increasing crop yields worldwide. Thus, it is essential to discuss the agricultural development process; the historical perspective, types and specific uses of pesticides; and pesticide behavior, its contamination, and adverse effects on the natural environment. The review study indicates that agricultural development has a long history in many places around the world. The history of pesticide use can be divided into three periods of time. Pesticides are classified by different classification terms such as chemical classes, functional groups, modes of action, and toxicity. Pesticides are used to kill pests and control weeds using chemical ingredients; hence, they can also be toxic to other organisms, including birds, fish, beneficial insects, and non-target plants, as well as air, water, soil, and crops. Moreover, pesticide contamination moves away from the target plants, resulting in environmental pollution. Such chemical residues impact human health through environmental and food contamination. In addition, climate change-related factors also impact on pesticide application and result in increased pesticide usage and pesticide pollution. Therefore, this review will provide the scientific information necessary for pesticide application and management in the future.

“…Runoff and drift are two main pathways to cause pesticide pollution in water [86]. The parcel's slope, soil type, texture, and structure combined with crop growth, row directionality, and climatic factors are the main aspects that strongly affect the runoff rate [157].…”

“…The following uncertainties limit the validity of the results of this research work. (1) the concentrations of pesticides across the different rice growing seasons are different (Zhu et al, 2017), but seasonal variation of pesticides were not investigated. Thus, the exposure and potential risk level of Pymetrozine may not present the real situation in this study.…”

Pymetrozine is one of the most common insecticides used in China. This study was conducted to analyse Pymetrozine's potential exposures through various environmental routes beyond the treatment area. The aim was to estimate the potential health risk for communities due to non-dietary exposure to Pymetrozine in soil and paddy water. Data on registration of pesticides in China, government reports, questionnaires, interviews, literature reviews as well as toxicological health investigations were evaluated to determine the hazard and dose-response characteristics of Pymetrozine. These were based on the US EPA exposure and human health risk assessment methods using exposure from soil and paddy water samples collected between 10 to 20 meters around the resident's location.The potential exposures from dermal contact through soil and paddy water were estimated.The potential cancer risk from the following routes was evaluated: the ingestion through soil; dermal contact exposure through soil; dermal contact exposure through paddy water; and the potential total cancer risk for residents was less than 1*10 -6 . These were within the acceptable risk levels. The potential hazard quotient (HQ) from acute and lifetime exposure by dermal contact through paddy water and soil; acute and lifetime exposure by soil ingestion for residents were less than 1, indicating an acceptable risk level, thus both potential cancer risk and hazard quotient (HQ) were relatively low. Potential human health risk assessment of Pymetrozine in soil and paddy water suggested that negligible cancer risk and non-cancer risk based on ingestion and dermal contact are the main potential routes of exposure to residents.

Pesticides are applied to protect crops from insects, weeds, and bacterial or fungal diseases during the growth. There would be a 78 percent loss of fruit output, a 54 percent loss of vegetable production, and a 32 percent loss of cereal production if pesticides were not used. When pesticides are applied to a target plant, they have the potential to enter the environment where they can affect non target organisms. Concerns have also been raised about pesticide currently uses and its impact on the environment with the possibility for hazardous or carcinogenic residues. This review paper provides basic information about the general types of pesticide in use and the role of pesticides in agriculture with its impact in environmental components. Int. J. Appl. Sci. Biotechnol. Vol 10(2): 75-83.
