Question

1. causes of sick building syndrome include all of the following except (a) radon and asbestos (b) chemical contaminants from indoor sources (c) chemical contaminants from outdoor sources (d) biological contaminants (e) inadequate ventilation 81. examine the following food web: which organism in the food web accumulates the highest concentration of a fat - soluble pollutant? (a) grass (b) grasshopper (c) sparrow (d) spider (e) hawk

Explanation:

• For question 80: Sick - building syndrome is caused by indoor pollutants like radon, asbestos, chemical and biological contaminants from indoor sources, and inadequate ventilation. Chemical contaminants from outdoor sources are less likely to cause sick - building syndrome directly as the building acts as a barrier.
• For question 81: Biomagnification causes fat - soluble pollutants to accumulate at higher levels in organisms at higher trophic levels. The hawk is at the top of the food web, so it will accumulate the highest concentration of a fat - soluble pollutant.
