What is the formula that summarizes pesticide risk, and what do its components represent?
hazard = exposure - toxicity, where exposure is the likelihood of harm and toxicity is the duration of exposure
hazard = toxicity x exposure, where toxicity is the capacity to cause injury and exposure is the means of entry
hazard = toxicity + exposure, where toxicity is the means of entry and exposure is the capacity to cause harm
hazard = toxicity / exposure, where toxicity is the severity of symptoms and exposure is the frequency of contact
2. hazard = toxicity x exposure, where toxicity is the capacity to cause injury and exposure is the means of entry

Toxicity refers to the potential for harm, while hazard refers to the product's chemical composition.
Toxicity is only relevant for acute injuries, while hazard pertains to chronic injuries.
Toxicity is a property of the pesticide itself, whereas hazard is the probability of harm occurring due to exposure.
Toxicity is determined by the method of application, while hazard is determined by the formulation of the pesticide.
