Environmental monitoring is much needed to help protect the public and the environment from the contaminants and pathogens. They are used to prepare environmental impacts and assessments to help establish the circumstances that can have a negative impact on the natural environment. There are many different types of monitoring carried out, which include air, water, and soil, which can help establish the right status of the environment. The different types of monitoring are conducted on different types of contaminations.

Air pollutants originate from vehicle emissions, refineries, power plants, and industrial processes. These pollutants include sulfur dioxide, nitrogen dioxide, carbon monoxide, etc. Soil and water can include microbiological, radioactive, synthetic, and volatile organic compounds. There are pesticides and herbicides, which can also be harmful. Heavy metal and organic contaminants are increasing in the parts of the environment due to excessive use. The metal contaminants have an increased presence in the aquatic food chain. For different pollutions there is different type of monitoring and sensors which is effective.

Air pollution: Air pollution is a constantly growing problem and is done via air sampling. The sampling can be passive, diffusive, and can be done by biomonitoring. Air pollution is done via air sampling. The samples can be passive, diffusive, and can have bioaccumulated air pollutants. Air pollutions can concentrate heavily influenced by the wind, and others can be taken into account.

Air pollution

Soil Monitoring: This is done through soil sampling, which includes soil erosion, salinity, and contaminations. The key here is to ensure that you have food contamination, which can regenerate forests and jungles and keep the air clean.

Water monitoring: This is a wide range of sampling methods that can depend on the environment and the types of material used for analysis. This type of water sampling is easy, which requires you to obtain the right samples and check the toxicity of the water.

There are numerous types of environmental sensors that depend on the monitoring specifications: the sensitivity and the size. Sensors can easily be divided into three main types, which include environmental factors.

Water monitoring

Trace metal sensors: This is Laser-induced breakdown spectroscopy, nanoelectrode, and miniature chemical flow probe sensor.

Radioisotopic sensors: With this sensor, one can easily understand the radiation effect, cadmium zinc, telluride detectors, and other low energy pin diabase spectrometer.

Volatile organic compound sensors: With Evanescent fiber-optic chemical senor, grating light reflection spectroscopy, miniature chemical flow probe sensor, and others can help you understand the number of toxins present in any organic compound.

Biological sensors: There are many compounds that are present, and with the right sensors, one can find the fatty acid methyl esters, which can allow you to understand the toxins present in the environment.
