Summary Introduction
To analyze:
The phase in which the urine of the children contains the maximum level of chlorpyrifos metabolite in the following experiment.
Given:
Levels of metabolites (breakdown products) of malathion and chlorpyrifos in the urine of children taking part in a study of effects of an organic diet:
Malathion metabolite Chlorpyrifos metabolite |
Study phase | No. of samples | Mean (µg/L) | Maximum (µg/L) | Mean (µg/L) | Maximum (µg/L) |
Nonorganic | 87 | 2.9 | 96.5 | 7.2 | 31.1 |
Organic | 116 | 0.3 | 7.4 | 1.7 | 17.1 |
Nonorganic | 156 | 4.4 | 263.1 | 5.8 | 25.3 |
Introduction:
The food substances that are produced as a result of the practice of organic farming is referred to as organic foods. These are beneficial for the human consumption, as these food substances do not tend to accumulate the toxic substances in the human body.

A patient with a rash gets a combination prescription from his physician to help alleviate the itching and moisturize the skin. The prescription is for 60% ingredient A and 40% of ingredient B for a total of 155 g (in a single tube). The patient has 3 refills on this prescription and wants to pick up the entire amount today: how much in g is that? Hint: 3 refills includes an original prescription so the total amount to be picked up is 4 tubes)
