Environmental monitoring in tourism

Environmental monitoring in tourism

A 11th grade student in her research work on ecology "Monitoring the ecological state of the air in the village" set a goal to evaluate the properties and characteristics of the air through the quantitative and qualitative determination of the content of various gases using test systems, indicator tubes and the lichen indication method. >

More about work:

The topic of the student's research and environmental project is relevant today, since recently the problems of environmental pollution have taken on a global character. Scientific and technological progress, consumer attitude towards nature and natural resources, ecological illiteracy have led to severe pollution of all natural environments, which means that humanity is in danger that must be prevented.

The project on ecology "Monitoring the ecological state of the air environment in the village" contains tables that present the results of the air study conducted by the author and the qualitative assessment of air pollution in the village using the lichen indication method.

Introduction

The most important pollutants are nitrogen oxides, sulfur dioxide, carbon monoxide, ozone, hydrocarbons, aldehydes, heavy metals (Pb, Cu, Zn, Cd, Cr), ammonia, atmospheric dust, radioactive isotopes, etc. Sulfur dioxide (SO2) is mainly used in the production of sulfuric acid, as well as a reducing agent, bleach, preservative, antioxidant, and is also one of the main air pollutants.

When studying the degree of environmental pollution with industrial gases, it is important to study the reaction of biological objects to pollutants - pollutants. Environmental monitoring is a system for monitoring the response of biological objects to the effects of pollutants. Environmental monitoring is the observation, assessment and forecast of measurements of the state of ecosystems and their elements caused by anthropogenic impact.

There are many sources of anthropogenic nature that cause air pollution, which leads to serious disruptions in the ecological balance in the biosphere. The chemical industry pollutes the air with a mixture of hazardous gases. Vehicle exhaust contains carbon monoxide, unburned volatile hydrocarbons, and nitrogen oxide. Of unstable impurities, sulfur dioxide escaping from factory pipes is very harmful to plants. During precipitation, it dissolves in water droplets and acid rain falls on the ground.

Acid rain is harmful to plants, leaves traces on them in the form of spots; for some soil inhabitants, worsens conditions for plant growth. Sulphurous gas is especially destructive for such conifers as common spruce and fir. Polluted air causes great harm to all living things. Lichens are very susceptible to sulfur dioxide.

In this regard, it is almost impossible to find lichens on tree trunks in large cities. A lot of harmful exhaust gases get into the air that is adjacent to the territory of busy motorways. Trees perceive this in different ways. In the crowns of some, the buds are damaged and wither, and below the shoots grow in bunches, as many buds awaken at once.
