Answer:
a contaminant concentration
Explanation:
The concentration of the ingested contaminant determines the toxicity potential of the contaminant. All chemicals are acute toxicants if they are ingested in large amounts. The target organs and mechanism of action of these toxicants may vary but their potential to become toxic depends entirely on their absorption concentration. For example, Ethanol causes CNS depression but may lead to Liver cirrhosis if the concentration in body is very high.
Answer:
28.2%.
Explanation:
Attack rate of any pathogen describes the speed or morbidity by which the new or emerging population is at risk by the attack of the pathogen.
The attack rate can be calculated by the formula:
Attack rate = people affected or at the risk of infection / Total population.
65 people are affected and 72 people also shows the symptoms.
Attack rate = 65 + 72 / 485
Attack rate = 137 / 485
Attack rate = 0.28.
The attack rate percent = 0.28 × 100 = 28%.
Hence, the answer is 28%.
Since pathogens are easily passed from person to person, they need large populations to spread and survive. If they did not have a large population, the pathogens would die out.
