OPs have replaced the banned organochlorine compounds and are a major cause of animal poisoning. Organochlorine pesticides (OCPs) - Trade or common use names. Based on acute toxicity, pesticides are assigned to a Toxicity Class. Many have been developed for plant and animal protection, and in general, they offer a distinct advantage by … In this study, we monitored the organochlorine contaminants in common swifts (Apus apus) in the years 2016 to 2018. Some pesticides are considered too hazardous for sale to the general public and are designated restricted use pesticides. Chapter 4 discussed organochlorine pesticides, a group of chemicals that was widely used in the past, but had many problems including broad spectrum toxicity that affected both target pests and nontarget species along with a very long persistence in the environment. Organochlorine pesticides (OCPs) are a type of synthetic pesticide known to be highly toxic, slow to degrade, and prone to building up in the environment. Dimethoate is a monocarboxylic acid amide that is N-methylacetamide in which one of the hydrogens of the methyl group attached to the carbonyl moiety is replaced by a (dimethoxyphosphorothioyl)sulfanediyl group. Therefore, people who use pesticides or regularly come in contact with them must understand the relative toxicity, potential health effects, and preventative measures to reduce exposure to the products they use. pesticides are used according to the label directions, toxic effects are not likely to occur because the amount of pesticide that people and pets may be exposed to is low compared to the doses fed to laboratory animals. Pesticides and human health: Pesticides can cause short-term adverse health effects, called acute effects, as well as chronic adverse effects that can occur months or years after exposure. 1997. A survey was conducted to examine the influence of pesticides on aquatic community in West Bengal, India. Acute, high-level toxicity is well characterized – acute effects after high-level exposure have been described for some of the organochlorine pesticides (e.g. Pesticide is a general word that describes numerous groups of insecticides, fungicides, herbicides, garden chemicals, household disinfectants and rodenticides that are operated to both destroy and protect from pests (He, 1994, Eldridge, 2008, El Nemr et al., 2012, El Nemr et al., 2012, El Nemr et al., 2012).These pesticides vary in their chemical and physical properties from one class to another.

Many organic compounds are produced by plants for the purpose of defending the host plant from predation. Because pesticides are toxic, they are also potentially hazardous to humans, animals, other organisms, and the environment. An organochloride, organochlorine compound, chlorocarbon, or chlorinated hydrocarbon is an organic compound containing at least one covalently bonded atom of chlorine that has an effect on the chemical behavior of the molecule.The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) provides common examples.

Pesticides and human health: Pesticides can cause short-term adverse health effects, called acute effects, as well as chronic adverse effects that can occur months or years after exposure. LD50/LC50: A common measure of toxicity is the lethal dose (LD50) or lethal concentration (LC50) Occupational and other domiciliary exposures are also possible. PCBs have caused well-documented episodes of mass poisoning called "Yusho" and "Yu Cheng“, that occurred in China, Province of Taiwan, and in Japan. Pesticides and TPs could be grouped into:(a) Hydrophobic, persistent, and bioaccumulable pesticides that are strongly bound to soil.

Many fragrances, e.g. Organochlorine pesticides are known to be one of the most persistent organic pollutants present in the environment. A survey was conducted to examine the influence of pesticides on aquatic community in West Bengal, India. A pesticide poisoning occurs when pesticides, chemicals intended to control a pest, affect non-target organisms such as humans, wildlife, plant, or bees.There are three types of pesticide poisoning.
