Chemistry and physics are the principle measures of pollution , not biological (impact on plants and animals) or organoleptic (tasting, smelling , feeling and seeing) The advantages are that the hard science methods are simple, quicker and reproducible. Living systems are driven by complex considerations (sex, age, season, species etc.) that may not be fully anticipated in reviewing the response.Hard science tests include such things as:
- filtration of air for particulate weight and observation
- gas chromatography (airborne organics)
- light spectrophotometry (hydrogen sulphide etc)
- chemical indicators (sulphur dioxide)
- cabon absorption (organics)

How living indicators measure pollutants?
Living indicators, such as certain species of plants and aquatic organisms, measure pollutants by responding to changes in their environment. For example, some plants may exhibit stunted growth or discoloration in response to soil contaminants, while aquatic organisms can show altered behavior or reproductive patterns in polluted water. These biological responses provide insights into the level and impact of pollutants, allowing for effective environmental monitoring and assessment. By studying these indicators, scientists can gauge ecosystem health and identify areas needing remediation.
What are the non living indicators that demonstrate environmental changes?
Non-living indicators of environmental changes include temperature variations, precipitation patterns, and soil composition shifts. These factors can reflect broader climate trends, such as global warming or drought conditions. Additionally, changes in water quality, such as pH levels and pollutant concentrations, can signal alterations in ecosystems. Monitoring these indicators helps assess the health of the environment and the impacts of human activities.

What are 3 living pollution indicators?
The aim of the second phase of the Pollution Atmosphérique et Affections Respiratoires Chroniques (PAARC) study, started in 1974, was to compare the long-term mortality between populations living in areas with different air pollution levels. In Bordeaux (France), four different areas were concerned by the study. The black smoke measures were realized between 1974 and 1981. After 1981, the stations set specifically for the study were not used any more. The purpose of this study was to estimate the evolution of air pollution in those areas between 1982 and 1997 using the measures of 12 Association de Prévention de la Pollution Atmosphérique (APPA) stations located in Bordeaux city but not in the PAARC areas. The method used was divided in three phases: a correlation study between the stations of the different networks, a selection of the pertinent stations and the setting up of indicators using the arithmetic means method. Monthly means concentrations were estimated from January 1982 to December 1997. Models showed a decrease in black smoke levels whatever the area. The difference in level from one area to another, existing between the areas in 1974, was still with predicted values in 1997, but less important. Black smoke mean concentration for 1982-1997 was, respectively, 16.4 and 16.2 microg/m3, in areas 1 and 2. It was a little bit higher in area 3 with 18.9 microg/m3. Area 4 still has the highest level with 26.3 microg/m3. To conclude, this method enabled to assess different air pollution levels at different times in the four areas of the PAARC study in Bordeaux. Those levels could be used to study the impact of the air pollution on long-term mortality on populations living in the areas considered.
Has pollution altered living things?
Yes, pollution has significantly altered living things in various ways. It can lead to genetic mutations, reproductive issues, and reduced populations of species. Pollution can also impact ecosystems and food chains, affecting the overall biodiversity and health of the environment.
How can living and non living indicators can measure levels if pollution?
A living indicator of pollution would be organisms dying or getting sick from the pollutants. A non-living indicator could be a high amount of smog or other pollutants in the air or on buildings.

Get you a hypothesis about air pollution?
Increased levels of air pollution are positively correlated with higher rates of respiratory illnesses and allergies in urban areas. This hypothesis suggests that individuals living in areas with high air pollution are more likely to experience adverse respiratory health effects compared to those in areas with lower pollution levels.
What was used as a measure of the standard of living during the 1920s?
During the 1920s, the standard of living was often measured by indicators such as income levels, consumption patterns, and access to consumer goods. The rise of mass production made items like automobiles, radios, and household appliances more accessible, reflecting improved living conditions. Additionally, changes in employment and wages contributed to a growing middle class, further indicating an elevated standard of living during this decade. Overall, economic indicators like GDP growth and consumer spending also played a crucial role in assessing living standards during this period.

What stats can be used to determine whether or not a place has a high standard of living?
Stats such as average income, cost of living index, employment rate, education level, healthcare access, crime rate, and pollution levels can be used to determine whether a place has a high standard of living. Additionally, factors like housing affordability, infrastructure quality, access to amenities, and overall quality of life indicators can also contribute to assessing the standard of living in a particular place.
