The most common exposure scenarios for<unk>  cases are accidental or suicidal poisonings, occupational exposure, by-stander exposure to off-target drift, and the general public who are exposed through environmental contamination. Accidental or suicidal Share of suicide deaths from<unk>  Self-poisoning with agricultural<unk> s represents a major hidden public health problem accounting for approximately one-third of all suicides worldwide. It is one of the most common forms of self-injury in the Global South. The World Health Organization estimates that 300,000 people die from self-harm each year in the Asia-Pacific region alone. Most cases of intentional<unk>  appear to be impulsive acts undertaken during stressful events, and the availability of<unk> s strongly influences the incidence of self poisoning.<unk> s are the agents most frequently used by farmers and students in India to commit suicide. Occupational<unk>  is an important occupational health issue because<unk> s are used in a large number of industries, which puts many different categories of workers at risk. Extensive use puts agricultural workers in particular at increased risk for<unk>  illnesses. Exposure can occur through inhalation of<unk>  fumes, and often occurs in settings including greenhouse spraying operations and other closed environments like tractor cabs or while operating rotary fan mist sprayers in facilities or locations with poor ventilation systems. Workers in other industries are at risk for exposure as well. For example, commercial availability of<unk> s in stores puts retail workers at risk for exposure and illness when they handle<unk>  products. The ubiquity of<unk> s puts emergency responders such as fire-fighters and police officers at risk, because they are often the first responders to emergency events and may be unaware of the presence of a poisoning hazard. The process of aircraft disinsection, in which<unk> s are used on inbound international flights for insect and disease control, can also make flight attendants sick. Different job functions can lead to different levels of exposure. Most occupational exposures are caused by absorption through exposed skin such as the face, hands, forearms, neck, and chest. This exposure is sometimes enhanced by inhalation in settings including spraying operations in greenhouses and other closed environments, tractor cabs, and the operation of rotary fan mist sprayers. Residential The majority of households in Canada use<unk> s while taking part in activities such as gardening. In Canada, 96 percent of households report having a lawn or a garden. 56 percent of the households who have a lawn or a garden utilize fertilizer or<unk> . This form of<unk>  use may contribute to the third type of poisoning, which is caused by long-term low-level exposure. As mentioned before, long-term low-level exposure affects individuals from sources such as<unk>  residues in food as well as contact with<unk>  residues in the air, water, soil, sediment, food materials, plants and animals.
