isoprenes contribution to ozon levels in Berlin was greatest in July of both years

july
(Home insulation type versus efficently ) Based on the data in the graph, which of the following insulation options i=s ineffective at insulating a home and greatly contributes to indoor air pollution
mineral fiber batt
Atmospheric deposition is receiving increased attention in the scientific community, and has become the subject of a specific research area in the environmental sciences. Acid rain is detrimental to our ecosystems and can be measured in several ways Which of the following methods would best identify changes from acid deposition in an area over time?
monitoring the long term chemical and biological parameters of an ecosystem
A researcher wants to determin if ponds and lakes downwind of a coal burning power plant are affect by the plants emissions. Which of the following would be the best parameter from water in the ponds and lakes to measure in oder to determine the effect of the plants emissions on the aquatic ecosystems
pH
which of the following points on the graph best illistrates the location where pollutans are most likely to accumulate as a result of a thermal inversion?
point D
Scientists are testing the effect of different scrubber technologies on the removas of pollutants from coal power plants. The scrubbers use a slurry of limestone and water. which of the following best describes the impact of mod
the amount of sulfur dioxide released will decrease
Scientists want to examine the effects of a coal-burning power plant on the pH of a lake that is downwind of the power plant. They take samples from a lake that is not downwind of the power plant to serve as a control. However, they did not realize that the lake they chose as a control group was a geothermal hot spring with acidic water. which of the following best describes how their choice of control group could affect the results of their experiment?
the coal burning power plant would not appear to have a large impact because the pH levels of the two lakes would be similar
Air pollution from a power plant is being monitored for levels of nitrogen dioxide and ground level ozone, The levels are measured daily at the same time. Which of the following best predicts the impact of a dark and couldy day on the reading for the levels of air pillutants measured?
there will be an increase in the level of nitrogen dioxide and a decrease in the level of ground level ozone
(atmospheric layers over a city) In addition to a nearby mountain range, which of the following environmental conditions would be required for the process in the diagram to occur?
A cool sea breeze and a high pressure system
(Effects of noise on wildlife) what is one potential impact of increased noise pollutions in national parks that is supported by the article?
prey populations are likey to increase in national parks because predators have a decreased ability to hear prey sounds
An air pollution expert set up a monitoring program to determine the amount of particulate matter (PM) leaving a farmer's field after crops were harvested and the soil was bare. She set up high-volume air samplers 10 meters from each edge of the square field and collected samples weekly for two months. When she looked at her data, she was surprised by how much the PM levels varied, both from site to site on a given date and over time at each site. which of the following parameters would have been best to measire to help explain the variation in her results
wind direction and speed
An experiment to evaluate the efficiency of wet and dry scrubber networks that filter particulate gas at different flow rates was conducted under different flow rate conditions. The results are shown below. which of the following best desribes the efficiencey of dry srubbers at removing particles that are less than 2 micrometers in diameter?
Dry scrubbers are less than 10% efficient at removing particles less than 1μm in size.
(Effects of noise on wildlife) which of the following clains is best supported by the evidence provided by the article?
Frog populaions may decrease in size as a result of males changing the pitch of their calls
(atmospheric layers over a city) which of the following best describes the process shown above?
Less dense, warm air creates a temperature inversion between more dense layers, trapping pollutants near the ground
which of the following best describes hwo a scientist could have accuratly study the effects of soil buffering on plant growth in a region that is affected by acid deposition downwind of a coal burning power plant?
Measure the changes in a plant height over a year in two different groups of trees the same distance from the power plant; one group is in topsoil and one group is in topsoil with limestone added
(Effects of noise on wildlife) Based on the authors claim in the article, which of the following statements best describes the effect of noise pollution on wildlife?
Noise pollution has a negative effect on wildlife activites such as mating, establishing territories, and predator prey interations
