For the most part, the purpose of environmental quality monitoring is to ensure that an organisation is complying with applicable laws and regulations or to reduce the risk of environmental and human health harm.
The development of advanced monitoring functions and devices is critical for improving the precision of environmental monitoring details and the cost-effectiveness of the environmental monitoring procedure such as human population, industrial endeavours, energy consumption, etc.
Overarching objectives, precise strategies, scheduled sampling procedures as well as projects within each strategy and timeframes are all included in a monitoring program. By providing a central data management centre, automatic environmental monitoring alerts, compliance inspection, authentication, quality control and report generation comparing different datasets.
EDMS make it easier for environmental monitoring and assessment programmes to be implemented and monitored.
Soil, air, and water are the three primary environmental monitoring categories. Scanners, sedimentation, electrostatic samples and impingers are just some of the environmental scanning and monitoring processes that are commonly used. A database management system (DBMS) can organise, analyse, and display collected data by various environmental monitoring technologies into actionable insights that aid decision-making.
Inequality in health, well-being and the number of years spent in a healthy state can all be traced back to the environment. Cancer, respiratory and cardiovascular system damage and death have all been linked to poor air quality.
Nonsmokers are more likely to develop heart disease and lung cancer as a result of exposure to secondhand smoke, which contains carcinogens and other harmful chemicals. Approximately 25% of all deaths and the global disease burden are due to environmental factors. People whose health has already been compromised are the most vulnerable to the negative effects of poor environmental quality.
One in every 12 children and adults in the United States suffers from asthma, which is caused, triggered, and exacerbated by environmental factors such as air pollution and secondhand smoke. In 2016, more than 122.5 million people in the United States lived in counties where air quality standards were not met. In 2011-2012, 58 million nonsmokers in the United States were exposed to secondhand smoke.
To maintain a healthy environment, the air, land, and water must be free of pollutants.
A wide range of factors, including secondhand smoking, carbon monoxide, allergies, lead, and toxic compounds, all contribute to disease and other health problems.
Pollution levels and human exposure can be monitored, healthy lifestyles can be established, and pollution threats can be taken into account when making decisions, all of which can help improve health and quality of life.
In order to determine how polluted the air is in a given city, the air quality index (AQI) is used. Shambhavi Shukla, a Senior Research Associate at the Centre for Science and Environment, says that prolonged exposure to 'bad' AQI can cause respiratory problems.
To calculate a sub-index for each of the eight pollutants that are tracked, the concentrations, standards, and estimated health impact are taken into consideration. AQI is determined by the worst sub-index, and the primary pollutant is the pollutant with the worst sub-index.
The AQI is divided into six parts by the CPCB (Central Pollution Control Board) air quality rules.
When the AQI is between 0 and 50, it is considered "good," 51-100, 101-200, 201-300, 301-400, and 401-500, it is considered "moderate," "poor," "very poor," and "severe."
All eight pollutants may not have been accounted for in every location.
The overall AQI can only be calculated using data for at least three pollutants, one of which must be PM2.5 or PM10.
According to Anumita Roy Chowdhury, (Centre of Science and Environment), a minimum of 16 hours of data is required to generate a sub-index.
As the AQI increases, so do the health risks.
When the AQI is adequate, sensitive people may experience some mild breathing problems. However, when the AQI is excessive, healthy people may experience respiratory effects and people with existing respiratory problems may experience serious health problems.
Cloudy water is unappealing to many people.
Wastewater treatment costs will rise because of the increased turbidity. Toxic bacteria may hide under a thick layer of particles, making it more difficult to remove them.
Solids can be suspended or dissolved in water. After passing a water sample via a glass fibre filter, suspended solids will continue to stat at the top of the filter. On the other side, any dissolved substances will pass through the water and remain there.
When trying to figure out how much solids are in a given amount of water, it's common practice to take the total dissolved solids into account.
To find out how much organic matter stays in the water, look at the total dissolved solids. Dissolved solids (TDS) in water can be divided into two categories:
